Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.
Fig. 1 is a flowchart of steps of a method for identifying a coded image according to an embodiment of the present invention, where as shown in fig. 1, the method may be applied to a mobile terminal, and the method may include:
In the embodiment of the invention, when a user of the mobile terminal needs to identify the coded image, the user can perform operations such as clicking or double clicking on the coded image identification icon, so that the coded image scanning function of the mobile terminal is started, then, the user can control the camera of the mobile terminal to collect the first coded image, so that the first coded image is input into the mobile terminal, and accordingly, the mobile terminal can identify the input first coded image, namely, information in the first coded image is acquired, and corresponding target operation is executed based on the information. The first encoded image may be an encoded image provided on the target device for performing a target operation on the target device, for example, a two-dimensional code image provided on a sharing bicycle for turning on the bicycle.
And 102, if the first coded image is failed to be identified, storing the first coded image, and identifying a second coded image input within a preset time length.
In practical applications, a first encoded image set on a target device may be damaged, for example, damaged by human malice, damaged due to scratch in a using process, and the like, so that the first encoded image may have a problem of information loss and insufficient information, that is, an information amount of information included in the first encoded image is smaller than an information amount of information required for performing a target operation, which may cause a failure of an operation of identifying the first encoded image by a mobile terminal, that is, the mobile terminal may not perform the target operation on the target device based on the information included in the first encoded image. Accordingly, in order to improve the probability that the target operation can be performed, in the case that the identification of the first encoded image fails, if the user wants to continue to implement the target operation, the user often continues to input the second encoded image within a preset time, and therefore, in this step, the mobile terminal may identify the encoded image input by the user within a preset time length as the second encoded image for the target operation, where the preset time length may be a maximum time interval time length of the scanning operation when the user implements the target operation by continuously scanning multiple encoded images, where the maximum time interval time length may be obtained by testing multiple users in advance. Specifically, the second encoded image may be an encoded image having the same content as the first encoded image and different position, for example, two encoded images respectively disposed at a head and a tail of a shared bicycle, where the encoded image input by the user first is the first encoded image and the encoded image input by the user later is the second encoded image. Further, in order to avoid the problem that the target operation cannot be executed due to failure of identification of the second encoded image, in this step, the mobile terminal may store the first encoded image when identification of the first encoded image fails, so as to save part of information carried in the first encoded image.
And 103, if the second coded image is failed to be identified, storing the second coded image.
In practical applications, the second encoded image set on the target device may also be damaged, for example, damaged by human malice, damaged due to scratch in the using process, and the like, so that the second encoded image may also have a problem of information loss and insufficient information, that is, the information amount of the information included in the second two-dimensional code image is smaller than the information amount of the information required for executing the target operation, and thus, the identification operation of the mobile terminal on the second encoded image may be failed, that is, the mobile terminal cannot execute the target operation on the target device based on the second encoded image. Further, since the damaged area of the first coded image may be different from the damaged area of the second coded image, the information missing from the first coded image is different from the information missing from the second coded image, that is, the first coded image may include the information missing from the second coded image, and the second coded image may include the information missing from the first coded image, in this step, the mobile terminal may store the second coded image when the identification of the second coded image fails, so as to save part of the information carried in the second coded image.
And 104, generating a target coded image based on the stored second coded image and the first coded image.
In this step, the mobile terminal may combine the second encoded image and the first encoded image to generate the target encoded image, so as to integrate the information contained in the first encoded image and the information contained in the second encoded image, and maximally enrich the amount of information that can be used to perform the target operation.
In the embodiment of the present invention, since the target encoded image is generated by combining the second encoded image and the first encoded image, information contained in the target encoded image is often richer and more complete, and thus, the information contained in the target encoded image can more probably satisfy information required for performing the target operation, and in this step, the mobile terminal can perform the target operation based on the target encoded image, so as to further improve the probability that the target encoding operation can be performed.
In summary, according to the code image identification method provided by the embodiment of the present invention, the mobile terminal may identify an input first code image, store the first code image if the first code image fails to be identified, identify a second code image input within a preset time duration, and improve the probability that the target operation can be performed by identifying the second code image, further, if the second code image fails to be identified, store the second code image, generate the target code image based on the stored second code image and the first code image, and finally perform the target operation based on the target code image, so that the target code image can be generated to combine information in the first code image and the second code image, thereby further improving the probability that the target operation can be performed.
Fig. 2-1 is a flowchart illustrating steps of another method for encoding pictures according to an embodiment of the present invention, which may be applied to a mobile terminal, as shown in fig. 2-1, and which may include:
Specifically, the implementation manner of this step is similar to that of step 101, and accordingly, reference may be made to step 101, which is not described herein again in this embodiment of the present invention.
In order to facilitate a user to know that the information contained in the first coded image is insufficient in time, the first coded image is failed to be identified, and then the second coded image is input to the mobile terminal in time, in the embodiment of the invention, the mobile terminal can also display second reminding information after the first coded image is stored and before the second coded image is identified; the second reminding information may be, for example, text-type information whose content is "target operation cannot be executed through the encoded image, please scan other available encoded images", or other types of information of other contents, such as voice-type information and video-type information, which is not limited in the embodiment of the present invention.
And 203, if the second coded image is failed to be identified, storing the second coded image.
Specifically, the implementation manner of this step is similar to that of step 103, and accordingly, reference may be made to step 103, which is not described herein again in this embodiment of the present invention.
Specifically, this step can be realized by the following substeps (1) to (4):
substep (1): and adjusting the shape of the first coded image and the shape of the second coded image to a preset shape by using a preset image correction algorithm.
In this step, the preset image correction algorithm may be affine transformation, where the affine transformation is composed of a non-singular linear transformation followed by a translation transformation, and in the case of a finite dimension, an affine transformation may correspond to multiplication of a matrix and a vector, which is a linear transformation from a two-dimensional coordinate to a two-dimensional coordinate, and the affine transformation may maintain straightness of a two-dimensional figure, that is, a straight line still becomes a straight line after the affine transformation, and parallelism of the two-dimensional image, that is, a relative positional relationship between straight lines remains unchanged, a parallel line still becomes a parallel line after the affine transformation, and a positional order of points on the straight line does not change, and three pairs of non-collinear corresponding points may determine a unique affine transformation. When performing the correction, the first encoded image and the second encoded image may be respectively subjected to operations such as translation, scaling, and rotation based on affine transformation to achieve adjustment of the shape of the first encoded image and the shape of the second encoded image into preset shapes, where the preset shapes may be squares that are set in advance for convenience of processing the images in subsequent steps, and of course, the preset shapes may also be other shapes.
Substep (2): and respectively determining a first effective region in the first coded image and a second effective region in the second coded image by using a preset image detection algorithm.
In this step, a first effective region in the first encoded image indicates that the first encoded image still carries an information region without being damaged, and a second effective region in the second encoded image indicates that the second encoded image still carries an information region without being damaged. In practical application, after the coded image is damaged, the content of the damaged area tends to become fuzzy, so in this step, the mobile terminal can obtain a first effective area by detecting a clear edge regular area in the first coded image, and obtain a second effective area by detecting a clear edge regular area in the second coded image.
Specifically, the grayscale image corresponding to the first encoded image and the grayscale image corresponding to the second encoded image can be obtained by performing a graying process on the first encoded image and the second encoded image, where the graying process is a process of converting a color image into a grayscale image, and the grayscale image obtained after the graying process can reflect the distribution and characteristics of the overall and local chromaticity and luminance levels of the whole image. In the embodiment of the invention, the gray processing is carried out, so that the calculation amount for the subsequent processing of the first coded image and the second coded image is reduced, and the consumption of terminal system resources is reduced. Then, the edge maps of the first encoded image and the second encoded image may be respectively calculated based on a preset edge operator, where the preset edge operator may be a Sobel operator or a laplacian operator, and further, the valid regions in the first encoded image and the second encoded image may be respectively determined based on the edge map of the first encoded image and the edge map of the second encoded image. Of course, in practical applications, the effective region may also be determined based on other manners, for example, because the content of the damaged region tends to become blurred, and therefore, the texture features of the image in the undamaged region in the encoded image and the texture features of the image in the damaged region tend to have a large difference, so the mobile terminal may also determine the second effective region in the second encoded image based on the extracted texture features by extracting the texture features of various positions in the first encoded image, determining the first effective region in the first encoded image based on the extracted texture features, and extracting the texture features of various positions in the second encoded image.
Substep (3): and setting the pixel value of each pixel point in the first coding image except the first effective region as a preset value to obtain the first effective region image.
In this step, the preset value may be preset according to actual requirements, for example, the preset value may be 0, and the preset value may also be 255, which is not limited in the embodiment of the present invention. Fig. 2-2 is a schematic diagram of a first encoded image according to an embodiment of the present invention, and as shown in fig. 2-2, an area a covered by oblique lines represents a first effective area, so that the mobile terminal may set a pixel value of each pixel point in an area other than the area a, that is, an area b, to a preset value, and after the setting is completed, the first effective area image may be obtained.
Substep (4): and setting the pixel value of each pixel point in the second coding image except the second effective region as the preset value to obtain the second effective region image.
For example, fig. 2 to 3 are schematic diagrams of a second encoded image according to an embodiment of the present invention, as shown in fig. 2 to 3, a region c covered by oblique lines represents a second effective region, so that the mobile terminal may set a pixel value of each pixel point in a region other than the region c, that is, the region d, to a preset value, and after the setting is completed, a second effective region image may be obtained.
And step 205, combining the first effective area image and the second effective area image to generate a target coded image.
Specifically, this step can be realized by the following substeps (5) to (7):
substep (5): and determining one of the first effective area image and the second effective area image as a reference image, and determining the other image as a contrast image.
Specifically, the mobile terminal may use the first effective area image as a reference image and the second effective area image as a comparison image, or may use the second effective area image as a reference image and the first effective area image as a comparison image, which is not limited in this embodiment of the present invention.
Substep (6): and for each reference pixel point in the reference image, if the pixel value of the reference pixel point is different from the pixel value of the comparison pixel point at the same position in the comparison image, and the pixel value of the reference pixel point is a preset value, adjusting the pixel value of the reference pixel point to be the pixel value of the comparison pixel point at the same position in the comparison image.
In this step, the pixel points included in the reference image are reference pixel points, and the pixel points included in the comparison image are comparison pixel points, specifically, the mobile terminal can compare each reference pixel point in the reference image with the pixel values of the comparison pixel points at the same position in the comparison image in sequence, and if the pixel value of the reference pixel point in the reference image is the same as the pixel value of the comparison pixel point at the same position in the comparison image, it can be determined that both the reference pixel point in the reference image and the comparison pixel point at the same position in the comparison image carry information, or both the reference pixel point in the reference image and the comparison pixel point at the same position in the comparison image are damaged pixel points which do not carry information, and therefore, the reference pixel point can not be processed.
Further, if the pixel value of the reference pixel point in the reference image is different from the pixel value of the comparison pixel point at the same position in the comparison image, at this time, whether the pixel value of the reference pixel point is a preset value can be further judged, if the pixel value of the reference pixel point is not the preset value, it can be determined that the reference pixel point in the reference image carries information, and therefore, the reference pixel point may not be processed, and further, if the pixel value of the reference pixel point is a preset value, the reference pixel point in the reference image can be determined as a damaged pixel point which does not carry information, and the contrast pixel points at the same position in the contrast image carry information, and at the moment, the pixel value of the reference pixel point can be adjusted to the pixel value of the contrast pixel point at the same position in the contrast image so as to enrich the information carried in the reference image.
Substep (7): and determining the adjusted reference image as a target coding image.
Correspondingly, after all the reference pixel points are traversed and all the reference pixel points needing to be adjusted are adjusted, the adjusted reference image can be determined as a target coded image, and information carried in the target coded image is all information carried in the first coded image and the second coded image.
Specifically, in this step, the mobile terminal may first analyze the target encoded image to obtain information included in the target encoded image, for example, the black lattice in the target encoded image may be analyzed to be 1, the white lattice may be analyzed to be 0, and the information is sorted according to a preset sequence, so as to obtain a character string in the target encoded image, where the character string is the information included in the target encoded image. Then, if the information amount of the information contained in the target encoded image is not less than the information amount of the information required to perform the target operation, the mobile terminal may perform the target operation according to the information contained in the target encoded image.
For example, the mobile terminal may determine whether the length of the parsed character string matches a preset length, and if the length of the character string is not less than the preset length, it may be considered that the information included in the target encoded image is sufficient, and at this time, the target operation may be performed according to the information included in the target encoded image. It should be noted that, in an actual application scenario, a plurality of encoded images may be set for a target operation, that is, a plurality of second encoded images exist, and therefore, in the embodiment of the present invention, when the target operation cannot be executed based on the target encoded image, another second encoded image input by a user may be identified, and if the identification fails, the other second encoded image and the target encoded image may be combined to continue the synthesis by the above method, so as to improve the probability that the target operation can be executed.
In summary, in another encoded image recognition method provided by the embodiments of the present invention, a mobile terminal may recognize an input first encoded image, store the first encoded image if the first encoded image is failed to be recognized, recognize a second encoded image input within a preset time duration, and increase a probability that a target operation can be performed by recognizing the second encoded image, and further, if the second encoded image is failed to be recognized, the mobile terminal may determine a first valid region image based on the first encoded image, determine a second valid region image based on the second encoded image, combine the first valid region image and the second valid region image to generate a target encoded image, so that all information carried in the first encoded image and the second encoded image can be carried in the target encoded image, and finally perform the target operation based on the target encoded image, further increasing the probability that the target operation can be performed.
