Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Example one

The shooting method provided by the embodiment of the application is applied to electronic equipment.

Referring to fig. 1, a flowchart illustrating steps of a shooting method provided in an embodiment of the present application is shown.

Step 101, acquiring a shooting preview picture containing the shot object, and determining the color information of the shot object from the shooting preview picture.

In the embodiment of the present application, the electronic device may be an electronic device without a Camera, such as a Personal Computer (PC), a server, and the like, and the electronic device may also be an electronic device with a Camera, such as a Single Lens Reflex Camera (SLR Camera), a non-reflective plate Camera (Mirrorless Camera), a smart phone, and the like.

When the electronic device without a camera is adopted, the electronic device without a camera and other cameras or electronic devices with cameras can jointly form a shooting system. For example, in the embodiment of the present application, the scheme may be applied to a personal computer, and the personal computer and the single lens reflex camera may be connected in a wireless or wired manner to form a shooting system together.

In a process of taking a picture, generally, a camera function needs to be turned on, and then, an image within a view range is captured by an image sensor to generate a shooting preview image, the shooting preview image is an image captured by the image sensor, and a user adjusts camera parameters, a view angle and the like according to the shooting preview image, and then presses a shutter to shoot the image after the adjustment is completed.

In the embodiment of the present application, after the shooting preview screen is acquired, color recognition may be performed on a subject (for example, a vehicle) in the shooting preview screen to determine color information of the subject in the shooting preview screen. The color information may include the main color of the object, or may include the proportion of a plurality of colors, for example, the color information of the object may be red, and the color information of the object may be (20% red +80% blue). It should be noted that the color can be represented by a color code given in the color standard, for example, the color code FF0000 represents positive red, and the color code FFFFFF represents pure white. The real-time example of the application does not specifically limit the color standard, and technicians can select a proper color standard according to actual needs.

Specifically, in an embodiment, since the subject is usually placed at the center of the picture when the picture is taken, that is, the subject is usually in the middle area in the shooting preview picture, in order to improve the efficiency of color information determination and reduce resource consumption, a preset area may be directly set at the center of the shooting preview picture, and the color of the image in the preset area is extracted to obtain the color information of the preset area, and then the color information of the preset area is directly used as the color information of the subject. Furthermore, the preset area can be adjusted according to the requirements of the user, and the user can adjust the size and the position of the preset area in the shooting preview picture according to the size and the position of the shot object in the shooting preview picture.

In another embodiment, in order to improve the accuracy of the color information determination, the object may be actively identified to determine the position of the object in the shooting preview picture and the shape of the object in the shooting preview picture, so as to accurately extract the pixel information of the area in which the object is located in the shooting preview picture, and determine the color information of the object according to the extracted pixel information.

For example, the object in the shooting preview picture can be recognized by the object recognition neural network model and the area where the object is located is determined, so as to obtain the color information of the shooting preview picture in the area as the color information of the object.

And 102, determining shooting parameters aiming at the shot object according to the color information.

In a real shooting scene, a photographer usually needs to set shooting parameters of a camera according to colors of objects to be shot, so as to obtain a better shooting effect for the objects with different colors. For example, in a scene of shooting a vehicle, since white car paint reflects more light, when shooting a white vehicle, it may be necessary to shoot at a higher shutter speed to avoid overexposure; black car paint reflects less light, so when shooting a black car, it may be necessary to shoot at a lower shutter speed to avoid underexposure; red car paints reflect light with a low color temperature (the unit of measure of the color components contained in the light), which causes the ambient light to be warm and needs to be photographed with a corresponding white balance value to obtain an image with the correct color temperature. In order to obtain a good image capturing effect for different color objects, various image capturing parameters may be determined according to the color of the object, including shutter speed (exposure time), white balance, aperture size, and sensitivity (ISO value).

The shutter speed represents the time length of opening a camera shutter when a picture is taken, the longer the time length of opening the shutter is, the more light rays participating in sensitization are, and the higher the brightness of the shot image is under the condition that other shooting parameters are not changed; conversely, the lower the brightness of the captured image.

The white balance setting can correct the color temperature deviation of the image, and the correct white balance setting can better restore the color of the shot object in shooting. If the white balance is deviated, the photographed image may deviate from the color of the subject itself, resulting in a warm or cold image color.

The camera imaging utilizes a pinhole imaging principle, light rays are imaged on an image sensor through a pinhole in a lens, an aperture is a device for controlling the size of the pinhole, the larger the aperture is, the larger the diameter of the formed pinhole is, the more light rays participate in imaging in unit time are, the smaller the aperture is, the smaller the diameter of the formed pinhole is, and the fewer light rays participate in imaging in unit time are.

Sensitivity represents the sensitivity of a negative film (image sensor) used for imaging by a camera to light, and the higher the sensitivity, the more sensitive the image sensor to light, and the higher the brightness of the imaging result with the same light flux.

In this embodiment of the application, a technician or a user may determine, in advance, shooting parameters matched with each color information according to experience or related calculation, set the shooting parameters corresponding to each color information, establish a color-parameter correspondence between the color information and one or more shooting parameters, and after obtaining the color information of a subject, may query the color-parameter correspondence according to the color information of the subject, thereby determining the required shooting parameters, where the color information may include a color code, a color name, a color identification code, or the like.

Further, the color information of the object to be shot can also be input into a preset shooting parameter determination model, so as to obtain the shooting parameters output by the shooting parameter determination model. The shooting parameter determination model can be obtained based on neural network model training, and can also be a mathematical model constructed by technicians. It should be noted that, a skilled person may construct the shooting parameter determination model according to actual needs, and the form and the generation method of the shooting parameter determination model in the embodiment of the present application are not particularly limited.

And 103, shooting the shot object based on the shooting parameters to obtain a target image.

In the embodiment of the present application, after the shooting parameters are obtained, an image may be shot based on the shooting parameters. The user can also adopt the method to shoot a plurality of pictures for the same shot object, in this case, because the color of the same shot object does not change, the shooting parameters can be determined by adopting the method only during the first shooting, and the shooting parameters determined during the first shooting are used in the subsequent shooting process, so that the shooting efficiency is improved, and the calculation resources consumed by image shooting are reduced.

For example, a user shoots a black automobile in a studio, and needs to shoot a plurality of photos to synthesize a panoramic animation of the black automobile, before shooting a first photo, color information of the black automobile can be determined by shooting a preview picture, corresponding shooting parameters are determined according to the color information of the black automobile, the shooting parameters are used for shooting a plurality of photos at different angles of the black automobile, because the light in the studio is constant, a shot object is constant, the shooting parameters are constant, the pictures of the shot photos are uniform, and the panoramic animation of the automobile with a better effect can be synthesized by the photos subsequently.

In summary, the shooting method provided by the present application includes: acquiring a shooting preview picture containing a shot object, and determining color information of the shot object from the shooting preview picture; determining shooting parameters corresponding to the color information; and shooting the shot object based on the shooting parameters to obtain a target image containing the shot object. The method and the device can determine the color information of the shot object in the preview picture by shooting when the picture is shot, determine the shooting parameters matched with the color of the shot object according to the color information of the shot object, shoot the shot object according to the shooting parameters matched with the color of the shot object, and obtain the target image, therefore, the corresponding shooting parameters can be automatically set for the shot objects with different colors, the same shooting parameters can be accurately set for the shot objects with the same color, the shooting consistency for the different shot objects is improved, the method and the device not only contribute to improving the shooting effect for the shot objects with different colors, but also avoid the trouble that the camera needs to be manually adjusted after the shot objects with different colors are switched, and the shooting efficiency is improved.

Example two

Referring to fig. 2, fig. 2 is a flowchart illustrating steps of another shooting method provided in the embodiment of the present application, which may include the following steps:

step 201, acquiring a shooting preview picture containing the shot object, and determining the color information of the shot object from the shooting preview picture.

This step can be referred to as step 101, and is not described in detail in this embodiment of the present application.

In addition, in the embodiment of the present application, the color recognition model may also be used to determine the color category of the subject. Technicians can train the neural network model through a training set formed by the sample images and the color marking information corresponding to the sample images to obtain a color recognition model capable of determining the color codes of the input images.

Optionally, step 201 may include:

in the sub-step 2011, a color recognition model is input to the photographed preview image, and a color code output by the color recognition model is obtained.

In one embodiment, the color recognition model may include two parts, namely, a subject extraction sub-model and a color recognition sub-model, and the color code of the subject in the captured preview picture may be determined by directly inputting the captured preview picture into the color recognition model, recognizing the subject by the subject extraction sub-model and determining the boundary line of the subject, inputting the image part in the boundary line in the captured preview picture into the color recognition sub-model, and performing color recognition on the image part in the boundary line by the color recognition sub-model.

In another embodiment, the color recognition model may not recognize and extract the subject in the photographing preview screen. Before inputting the color recognition model into the shooting preview picture, a preset area corresponding to the shot object is set in the shooting preview picture in an automatic or manual mode, then the color recognition model is input into the shooting preview picture in the preset area, and the color recognition model performs color recognition on the shooting preview picture in the preset area so as to determine the color code of the shot object in the shooting preview picture.

A substep 2012 of determining a color class of the subject based on the color coding.

Millions of color codes are typically included in a color standard library, and a generalized "red" may correspond to tens of thousands of different codes, such as a pink code FFC0CB, a deep red code DC143C, and so on. In the embodiment of the application, based on the cost performance consideration, it may not be necessary to set corresponding shooting parameters for each color code, and only tens or hundreds of small numbers of shooting parameters may be set, so that the shooting requirement may be met. Thus, color codes may be categorized, with multiple color codes corresponding to a color category, where a color category may include red, green, blue, purple, and the like.

For example, the technician may set 14 color categories of black, white, silver, gray, red, blue, green, yellow, orange, brown, purple, gold, powder, champagne, and associate each color code with one of the 14 color categories, thereby determining the color category to which the color code corresponds after obtaining the color code.

In the embodiment of the application, the color code is output by the color recognition model, and then the color code is converted into the color category, so that adjustment operations such as increase, decrease, deletion, modification and the like of the color category can be conveniently performed by technicians. It should be noted that the color recognition model may also be trained as a model capable of directly outputting color classes.

Step 202, obtaining a target parameter corresponding relation, wherein the target parameter corresponding relation comprises a corresponding relation between color information and shooting parameters.

In this embodiment, a technician or a user may determine, in advance, shooting parameters matched with each color information according to experience or related calculation, set the shooting parameters corresponding to each color information, establish a target parameter corresponding relationship between the color information and one or more shooting parameters, and after obtaining the color information of a subject, may query the target parameter corresponding relationship according to the color information of the subject, thereby determining a required shooting parameter, where the color information may include a color category.

Further, according to the object type of the object, even if the color information is the same, different shooting parameters may need to be used for shooting, so as to obtain a better shooting effect for different types of objects. The object type may represent, among other things, the kind of object, such as a vehicle, a person, a building, a plant, etc. Thus, the technician can also set multiple sets of parameter correspondences for different object types, each set corresponding to one object type. Therefore, the corresponding target parameter corresponding relation can be determined according to the object type of the shot object.

Specifically, the target parameter correspondence corresponding to the subject may be determined by the following method of sub-step 2021 to sub-step 2022.

Step 202 may include:

substep 2021, determining an object type of the subject.

In the embodiment of the application, an object type option can be provided for a user, so that the user can select an object type corresponding to a shot object to be shot. The object type determination model can be trained in advance, and the object type determination model can be used for identifying the shot object in the shooting preview picture so as to determine the object type of the shot object. It should be noted that, a skilled person may flexibly select a method for determining an object type of a subject according to actual needs, and this is not particularly limited in the embodiment of the present application.

And substep 2022, determining a corresponding target parameter corresponding relation according to the object type.

In this embodiment of the present application, a correspondence between the object type and the parameter correspondence may also be included, and after the object type of the subject is determined, the target parameter correspondence corresponding to the object type of the subject may be determined according to the correspondence between the object type and the parameter correspondence.

Step 203, determining the shooting parameters corresponding to the color information of the shot object according to the target parameter corresponding relation.

Since the target parameter corresponding relationship includes the corresponding relationship between the color information and the shooting parameter, after the target parameter corresponding relationship of the shot object is obtained, the shooting parameter corresponding to the shot object can be determined according to the color information of the shot object. Therefore, the shot object can be shot through the shooting parameters in the subsequent process, and a better shooting effect is achieved.

And step 204, determining the current size of the object in the shooting preview screen and the target size set for the object.

In a plurality of shooting scenes, a plurality of corresponding pictures are generally required to be shot at a plurality of angles of the same object, so that a plurality of pictures are combined. It is necessary to make the shooting parameters the same between a plurality of images obtained by shooting a plurality of times and also to make the sizes of the objects in the plurality of images the same in order to perform the post-image synthesis. However, in order to capture multiple images, the relative position between the subject and the camera must be adjusted, which may cause the distance between the subject and the camera to change during the adjustment process, thereby affecting the effect

Therefore, in order to further improve convenience in a plurality of shooting scenes, in the embodiment of the present application, before shooting an image each time, the size of the subject in the shooting preview screen may be automatically adjusted so that the size of the subject in the shooting preview screen is the same in the image obtained by shooting each time.

Specifically, the subject in the shooting preview screen may be identified, and the current size of the subject in the shooting preview screen may be determined, and if the current size does not coincide with the target size, the size of the subject in the shooting preview screen may be adjusted to the target size. The size may be a width ratio, a height ratio, an area ratio, or the like of the subject on the shooting preview screen.

The target size may be set by the photographer before photographing, and for example, the target size may be set to 1/2 of the width of the photographing preview screen or the target size may be set to 1/3 of the height of the photographing preview screen. In addition, the size of the object in the first image captured in one multi-field capturing process may be determined as the target size, so that the size of the object in each of the subsequent images is the same as the size of the object in the first image in the multi-field capturing process. For example, a user needs to take a set (10) of vehicle pictures to generate a panoramic animation of the vehicle, and when taking the first picture, the user can directly take the picture without adjusting the size of the object according to the target size, and determine that the size of the object in the first picture obtained by shooting is 1/2 of the width of the shooting preview picture, and when taking the next 9 pictures, the user takes the 1/2 of the width of the shooting preview picture as the target size of the object every time shooting, so that the sizes of the objects in the 10 pictures obtained by shooting at this time are the same.

And step 205, adjusting the size of the shot object to the target size.

In the embodiment of the present application, the camera for photographing the subject may be a camera including a zoom function (optical zoom and/or digital zoom), and the size of the subject in the photographing preview screen may be changed by adjusting the focal length of the camera.

The camera for shooting the shot object can also be a camera mounted on a sliding rail or a mobile device, the camera can change the relative position with the shot object through the sliding rail or the mobile device so as to change the distance between the camera and the shot object, and the size of the shot object in the shooting preview picture can be adjusted based on the principle of big or small.

Optionally, step 205 may comprise:

sub-step 2051, in case the current size is smaller than the target size, increasing the camera focal length.

In the embodiment of the present application, for a shooting device equipped with an auto zoom function, the auto zoom may be directly performed by controlling the shooting device, so as to implement adjustment of the size of a subject, for a shooting device not equipped with an auto zoom function but only equipped with a manual zoom function, for example, a single lens reflex camera equipped with a manual zoom ring, a zoom device (e.g., a caricature zoom device) with a servo motor may be mounted on the zoom ring of the camera, and the zoom ring is rotated by controlling the servo motor to control the focal length of the camera, so as to implement adjustment of the size of a subject in a shooting preview screen. The zoom device can establish wired or wireless communication with the electronic equipment, receive a zoom control instruction sent by the electronic equipment, and drive a driving motor connected with a zoom ring to actuate according to the zoom control instruction, so that the control on the focal length of the camera is realized.

If the current size of the shot object is smaller than the target size, the focal length of the camera needs to be increased, the effect of zooming in the shot object is achieved, and the size of the shot object in the shooting preview picture is increased to the target size.

Sub-step 2052, in case the current size is larger than the target size, reducing the camera focal length.

If the current size of the shot object is larger than the target size, the focal length of the camera needs to be reduced, the effect of pushing away the shot object is achieved, and the size of the shot object in the shooting preview picture is reduced to the target size.

And step 206, shooting the shot object based on the shooting parameters to obtain a target image.

This step can be referred to as step 103, and is not described in detail in this embodiment of the present application.

In sub-step 2061, the viewing angle interval for the subject is acquired.

The user can set the surrounding angle range to be shot and the number of images to be shot, and the viewing angle interval between two adjacent images can be calculated according to the surrounding angle range and the number of the images, for example, the surrounding angle range set by the user is 360 degrees, and the number of the images to be shot is 10, so that the shooting device can be automatically controlled to rotate around the shot object, and the 36 degrees are used as the viewing angle interval to shoot 10 images around the shot object.

And a substep 2062 of controlling the camera to move around the object and shooting the object at the view angle interval to obtain a plurality of target images including the object, wherein the target images are shot based on the shooting parameters.

In the embodiment of the present application, the shooting device may include a shooting device capable of autonomous movement, so as to automatically shoot the object from different angles, for example, the shooting device may be formed by a camera and an annular turntable. Referring to fig. 3, fig. 3 shows a schematic diagram of a shooting device provided in an embodiment of the present application, and as shown in fig. 3, the shooting device may include an electronic device 31, a camera 32 connected (wirelessly or by wire) to the electronic device, and a turntable 33 connected to the electronic device, where the camera 32 is disposed on the turntable 33, and the camera 32 may shoot a subject 34 at different viewing angles under rotation of the turntable 33.

Referring to fig. 4, fig. 4 shows a shooting control Logic diagram provided in an embodiment of the present application, as shown in fig. 4, an electronic device may be connected to a Programmable Logic Controller (PLC) in a wired or wireless manner, and sends a rotation control signal to the PLC through a Modbus protocol, and after receiving the rotation control signal, the PLC sends a driving signal to a servo motor connected to the PLC to control the servo motor to drive a turntable on which a camera is mounted to rotate, so as to adjust a shooting angle of the camera with respect to a subject. The electronic equipment can also be connected with the zoom device in a wired or wireless mode, and sends a zoom control signal to the zoom device to drive the zoom ring of the camera to rotate, so that the focal length of the camera is adjusted. The electronic device may also connect the camera by wired or wireless means to control various functions of the camera, such as acquiring a photographing preview screen from the camera, transmitting photographing parameters to the camera, controlling the camera to photograph an image, and the like.

It should be noted that, in the process of shooting around the object, the shooting parameters may be set and the camera focal length may be adjusted by using the method in the foregoing steps. In addition, technicians may also use other methods to construct a shooting device capable of automatic movement, for example, an unmanned vehicle carrying a camera, which is not specifically limited in the embodiment of the present application.

For example, if the object is made of a mirror surface material or a glossy surface material, the surface gloss is high and the reflectance is high, and if the object is made of a matte material or a matte material, the surface gloss is low and the reflectance is low. In order to capture an image of a subject having a different material, it is generally necessary to set different imaging parameters in order to obtain a good imaging effect.

In the embodiment of the application, the shooting parameters can be determined according to the material information of the shot object, so that the shot objects of different materials can be shot well.

Specifically, the preset material detection model is input into the shooting preview picture, and the material information output by the material detection model is obtained.

Step 303, determining shooting parameters for the object based on the color information and the material information.

In an embodiment, after obtaining the color information and the material information of the object, the shooting parameters corresponding to the color information and the material information of the object may be determined according to the correspondence among the color information, the material information, and the shooting parameters. The correspondence between the three components can be preset by a technician or a user according to actual needs, and the correspondence between the three components is not specifically limited in the application.

In another embodiment, after obtaining the color information and the material information of the object, the method in the above steps may be adopted to determine the shooting parameters corresponding to the object according to the color information of the object, and then correct the shooting parameters corresponding to the object according to the material information of the object. For example, if the material information of the object is a matte material, the exposure time can be prolonged, the sensitivity can be increased, or the aperture size can be increased, so as to increase the exposure amount when the image is captured.

In the embodiment of the application, the shooting parameters for the shot object can be determined according to the color information of the shot object, and the shooting parameters for the shot object can be determined jointly according to the color information and the material information of the shot object, so that the shooting effect and the shooting efficiency for shooting the shot objects with different colors and materials are further improved.

Step 304, determining the current size of the object in the shooting preview picture and the target size set for the object.

This step can be referred to as step 204, and is not described in detail in this embodiment of the present application.

And 305, adjusting the size of the shot object to the target size.

And step 306, shooting the shot object based on the shooting parameters to obtain a target image.

This step can be referred to as step 206, and is not described in detail in this embodiment of the present application.
