Background
With the rapid development of scientific technology, laser projectors are well known and widely used in various aspects of daily life, such as teaching, meeting, home theater, etc. At present, in order to improve the visual experience of a user, a projector manufacturer gradually adopts a wall-mounted hard screen with a special optical microstructure to replace a roller shutter screen or a hanging screen in places with higher requirements on projection effects, such as a market or a home theater, and in the process of installing a laser projector, the requirements on the relative position between the projector and the wall-mounted hard screen matched with the projector are higher, otherwise, the projection image of the projector cannot completely correspond to the screen area of the wall-mounted hard screen, and the subsequent adjustment is difficult. Therefore, how to properly position the projector and the wall-mounted hard screen is a key factor for mounting the projector.
Because the projector and the projection screen have a fixed horizontal distance, and the lower edge of the projection screen has a vertical distance with the mounting table of the projector. Therefore, the existing projector positioning and mounting method is mainly realized through the following steps that firstly, the wall hanging height of the wall hanging hard screen is determined according to the vertical distance between the lower edge of the projection screen and the mounting desktop of the projector, the wall hanging hard screen is mounted, and then the projector is placed according to the fixed horizontal distance between the projector and the projection screen. Because the laser projector is composed of a plurality of subsystems, each subsystem is combined by a plurality of lenses to realize the propagation and imaging of light, and the manufacturing and assembly of each lens have tolerance, and the tolerance is accumulated to ensure that the projection heights between the laser projectors of the same model and different individuals have certain range difference, so the positioning heights of the wall-mounted hard screens are inconsistent, therefore, after the wall-mounted hard screens are installed and the projectors are placed, a user is required to finely adjust the projectors according to the position relation between the projection images of the projectors and the wall-mounted hard screens so as to ensure that the projection images of the projectors are completely matched with the screen areas of the wall-mounted hard screens.
However, since the laser projector is a precision optical device, when one parameter is adjusted, the next parameter is adjusted to affect the adjusted parameter, so that the projected image of the projector can be completely matched with the screen area of the wall-mounted hard screen after multiple adjustments, and if the adjustment range of the projector cannot cover the projection height difference range caused by the accumulated tolerance of each subsystem, no matter how the projector is adjusted, the projected image of the projector cannot be completely matched with the screen area of the wall-mounted hard screen, thereby increasing the debugging difficulty and complexity of the projector, reducing the installation efficiency, and having poor user experience.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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, but 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.
The laser projector is a high-precision device for transmitting pictures through laser beams, and mainly comprises a red-green-blue three-color light valve, a beam combining X prism, a projection lens, a driving light valve and other optical components. After the laser beams are expanded by corresponding optical elements and processing chips in the projector, the laser beams are transmitted to the beam combining X prism to integrate the three beams of laser, and then the integrated laser is transmitted to the projection screen by the projection lens, thereby completing the display process of the whole laser projector.
For the positioning installation of the projector and the wall-mounted hard screen matched with the projector, the existing positioning installation mode is that the installation positions of the projector and the wall-mounted hard screen are determined by superposing the projection image center of the projector and the center of the wall-mounted hard screen according to the specified distance between the projector and the wall to be hung and the height and the punching position of the wall-mounted hard screen and the installation desktop of the projector, and the installation sequence is as follows: the wall-mounted screen is installed first, and then the projector is installed.
In view of the problem of the characteristics of the projector itself, that is, the projector is composed of a plurality of subsystems, each subsystem includes a plurality of lenses, each lens has manufacturing tolerance and assembly tolerance, and the matching between the subsystems has assembly tolerance, so that the whole projector system has large accumulated tolerance. The cumulative tolerances cause differences in the range of projection heights for different projectors. Therefore, if the projector and the wall-mounted hard screen are installed according to the positioning installation method of the existing projector by adopting the theoretical size, the projected image of the projector is not matched with the wall-mounted hard screen.
Specifically, if the vertical distance between the projector and the lower edge of the wall-mounted hard screen is the theoretical design value, that is, if the adjustment support leg of the projector is located at the theoretical design position, due to the accumulated tolerance of the projector system, if the adjustment support leg is installed according to the existing method, the lower edge of the actual projection image of the projector will deviate from the vertical distance. At this time, the height difference of the projected image caused by the accumulated tolerance is compensated only by adjusting the height of the support legs on the projector or the height of the projected image on the wall surface to be hung. Due to the limitation of the adjustment range of the projection image of the projector equipment, the actual projection image still cannot be matched with the hung wall-mounted hard screen after long-time and multiple times of debugging.
In addition, the projector as a precision optical instrument should avoid the change of the original parameters, otherwise, the efficiency of the projection light path and the quality of the projected image may be affected. If the installer has insufficient debugging experience, it is time consuming for them to debug the projector multiple times, adding to the installation complexity. If the adjustment range of the projection image of the projector cannot cover the error between the actual projection height and the theoretical height value, the wall-mounted hard screen needs to be installed again. Therefore, the projector and the wall-mounted hard screen need to be adjusted repeatedly in the existing projector positioning and mounting mode, the debugging difficulty and complexity of the projector are increased, the mounting efficiency is reduced, and the customer experience is influenced.
The invention provides a projector positioning and mounting method and device, aiming at the defects of the existing projector positioning and mounting method, and solving the problems of high installation and debugging difficulty, complex installation process and low installation efficiency of the existing projector.
Fig. 1 is a schematic flow chart of a first embodiment of a projector positioning and mounting method provided by the present invention. The projector positioning and mounting method provided by the embodiment of the invention is suitable for positioning and mounting a projector system, and the projector system comprises the following steps: the projector and the wall-mounted hard screen matched with the projector. As shown in fig. 1, a projector positioning and mounting method provided in an embodiment of the present invention includes:
step 11: and manufacturing a positioning graphic card, wherein the positioning graphic card is used for determining the position of the wall hanging hard screen on the wall to be hung, and the positioning graphic card comprises a positioning reference point.
Alternatively, the positioning card may be produced by a production device integrated in the projector or by a function carried by the projector. The positioning graphic card needs to be manufactured according to the shape and the size of the wall-mounted hard screen, the theoretical shape and the size of the positioning graphic card need to be consistent with those of the wall-mounted hard screen, and the positioning graphic card also comprises a reference point for fixing or hanging the wall-mounted hard screen.
Step 12: and projecting the positioning chart card onto the wall surface to be hung through a projector.
Optionally, the positioning graphic card manufactured as above may be projected onto a wall surface to be hung by a projector, that is, a projection image having a shape and size consistent with the theoretical shape and size of the positioning graphic card may be projected onto the wall surface to be hung, and the projection image may have a shape and size adjustable consistent with a wall-mounted hard screen matched with the projector, and the projection image includes a positioning reference point of the wall-mounted hard screen.
Step 13: and adjusting the projection image of the positioning chart by adjusting the projector so that the shape and the size of the projection image are consistent with those of the wall-mounted hard screen.
Specifically, because reasons such as the projector locating position or the setting of the internal parameters of the projector can all influence the shape and the size of the projected image of the positioning chart card, the projected image of the positioning chart card projected by the projector can be adjusted by adjusting the internal parameters of the projector or calculating the position of the projector, and the shape and the size of the projected image are consistent with those of the wall hanging hard screen, so that the accurate position of the wall hanging hard screen on the wall to be hung can be determined, and the positioning reference points such as the punching point for installing the wall hanging hard screen or the hanging point for hanging the wall hanging hard screen can be accurately determined.
Step 14: recording the horizontal distance between the projector and the wall to be hung and the position of the positioning reference point on the wall to be hung so as to determine the mounting positions of the projector and the wall-mounted hard screen and realize the positioning and mounting of the projector and the wall-mounted hard screen.
After determining the accurate position of the wall hanging hard screen on the wall to be hung, recording the horizontal distance between the projector and the wall to be hung at the moment through the recording module, and the position of each positioning reference point on the wall to be hung, and further enabling the user to utilize the determined horizontal distance and the position of each positioning reference point, determining the installation position of the projector and the wall hanging hard screen matched with the projector, and further enabling the user to punch holes or install the hanging support at the reference positioning point, thereby fixing the projector on the mounting desktop of the projector, and fixing the wall hanging hard screen matched with the projector on the wall to be hung, and further completing the positioning and installation of the projector and the wall hanging hard screen.
According to the projector positioning and mounting method provided by the embodiment of the invention, the positioning graphic card is manufactured, the projector is used for projecting the positioning graphic card onto the wall surface to be hung, the projector is adjusted to adjust the projection image of the positioning graphic card, so that the shape and the size of the projection image are consistent with those of the wall-mounted hard screen, the horizontal distance between the projector and the wall surface to be hung and the position of a positioning reference point on the wall surface to be hung are further recorded, the mounting positions of the projector and the wall-mounted hard screen are determined, and the positioning and mounting of the projector and the wall-mounted hard screen are realized. According to the technical scheme, the projector and the mounting position of the wall-mounted hard screen matched with the projector can be quickly positioned through the manufactured positioning graphic card, the influence of accumulated tolerance inside the projector is avoided, the mounting complexity of the projector system is simplified, and the mounting efficiency is improved.
Fig. 2 is a schematic flow chart of a second embodiment of the projector positioning and mounting method provided by the present invention. The embodiment of the invention is further explained for the positioning and mounting method of the projector on the basis of the above embodiment. As shown in fig. 2, in the projector positioning and mounting method according to the embodiment of the present invention, step 13, namely, adjusting the projection image of the positioning card by adjusting the projector so that the shape and size of the projection image are consistent with those of the wall-mounted hard screen, specifically includes:
step 21: and (3) according to the shape of the wall-mounted hard screen, adjusting the projector to enable the shape of the projected image of the positioning graphic card to be consistent with the shape of the wall-mounted hard screen.
Specifically, after the projector is placed, the shape and the size of the positioning graphic card are projected onto the wall to be hung, theoretically, the shape of the projected image should be consistent with the shape of the wall-mounted hard screen, but the shape of the projected image of the positioning graphic card projected by the projector is not consistent with the shape of the wall-mounted hard screen due to the problem of parameter setting inside the projector, so that the shape of the projected image of the positioning graphic card can be consistent with the shape of the wall-mounted hard screen by adjusting the parameters of the projector.
For example, if the wall-mounted hard screen is rectangular, the positioning chart card should be made rectangular, the projection image projected on the wall to be mounted should also be rectangular, and if the projection image is not rectangular, but parallelogram or trapezoid, it indicates that the projection image is distorted, and the projector should be adjusted to make the projection image rectangular. Similarly, if the wall-mounted hard screen is hexagonal or otherwise shaped, then the projector should be adjusted so that the projected image shape of the alignment chart is the same as the shape of the wall-mounted hard screen.
In fact, this step can also be implemented by the built-in software of the projector, and the automatic correction of the projected image is implemented by the vertical keystone correction function provided in the projector, but at this time, the definition of the projected image may be reduced, which may affect the user experience.
Step 22: by adjusting the focal length of the projector, the size of the projected image of the positioning graphic card is consistent with that of the wall-mounted hard screen, and the focal length change of the projector is recorded.
Specifically, due to different accumulated tolerances in the individual projectors, the projected image size of different projectors at the same theoretical position may have a certain difference, so that for a certain projector, the projected image size of the positioning graphic card obtained by using the projector may not be consistent with the size of the wall-mounted hard screen. As is well known, the size of the projected image can be affected by the distance of the placement position of the projector and the size of the focal length, so that the size of the projected image of the positioning graphic card can be adjusted by the adjusting module in the projector by adjusting the focal length of the projector, so that the size of the projected image is consistent with the size of the wall-mounted hard screen, and the change of the focal length of the projector is recorded in the adjusting process.
Step 23: according to the focal length change of the projector, when the initial focal length of the projector is kept unchanged and the size of the projected image of the positioning graphic card is consistent with the size of the wall-mounted hard screen, the horizontal distance between the projector and the wall to be hung is calculated, so that a user can adjust the horizontal distance between the projector and the wall to be hung according to the horizontal distance, and the size of the projected image of the positioning graphic card is consistent with the size of the wall-mounted hard screen.
The method comprises the steps that the relation between focal length change and projected image size change and the corresponding relation between the projected image size and the horizontal distance between the projector and the wall surface to be hung can be set in a positioning and mounting device corresponding to the projector positioning and mounting method, when the focal length of the projector changes, the positioning and mounting device can calculate the size change of a projected image of a positioning graphic card according to the focal length change of the projector and the relation between the focal length change and the projected image size change, and further calculate the changed amount of the horizontal distance between the projector and the wall surface to be hung when the initial focal length of the projector is unchanged, and further determine the horizontal distance between the projector and the wall surface to be hung at the moment.
When the positioning and mounting device calculates that the initial focal length of the projector is kept unchanged and the size of the projected image of the positioning graphic card is consistent with the size of the wall-mounted hard screen, the horizontal distance between the projector and the wall to be hung is informed to a user through a voice mode or other communication modes, and then the user adjusts the horizontal distance between the projector and the wall to be hung according to the horizontal distance, so that the size of the projected image of the positioning graphic card is completely consistent with the size of the wall-mounted hard screen.
The projector positioning and mounting method provided by the embodiment of the invention can make the shape of the projected image of the positioning graphic card consistent with the shape of the wall hanging hard screen by adjusting the projector according to the shape of the wall hanging hard screen, make the size of the projected image of the positioning graphic card consistent with the size of the wall hanging hard screen by adjusting the focal length of the projector, record the focal length change of the projector, further calculate the horizontal distance between the projector and the wall to be hung according to the focal length change of the projector when the initial focal length of the projector is kept unchanged and the size of the projected image of the positioning graphic card is consistent with the size of the wall hanging hard screen, further ensure that the size of the projected image of the positioning graphic card is completely consistent with the size of the wall hanging hard screen, is convenient to adjust and accurate to position, does not need repeated adjustment by an installer, the positioning installation method is simplified, and the installation efficiency is high.
Fig. 3 is a schematic flow chart of a third embodiment of a projector positioning and mounting method provided by the present invention. The embodiment of the invention is further explained for the positioning and mounting method of the projector on the basis of the above embodiment. As shown in fig. 3, in the method for positioning and installing a projector according to the embodiment of the present invention, if the wall-mounted hard screen has a rectangular shape, the step 21 is to adjust the projector to make the projected image shape of the positioning card consistent with the shape of the wall-mounted hard screen by referring to the shape of the wall-mounted hard screen, and specifically includes:
step 31: in the process of adjusting the projector, whether the included angle between two adjacent edges of the projection image of the positioning chart is a right angle or not is monitored through the laser level meter.
At this stage, in a projector system used in home theater or shop displays, the wall-mounted hard screen matched with the projector is mainly rectangular, for example, the ratio of the length to the height of the wall-mounted hard screen is 16: 9. The embodiment of the invention is mainly explained by taking the shape of the wall-mounted hard screen as a rectangle as an example. In the embodiment, in order to make the shape of the projected image of the positioning graphic card consistent with the shape of the wall-mounted hard screen, that is, in order to ensure that the shape of the projected image of the positioning graphic card is rectangular, a laser level meter can be used for monitoring in the process of adjusting the projector, and then the included angle between two adjacent edges of the projected image of the positioning graphic card is kept to be a right angle.
Specifically, the laser level appearance can be selected to be the infrared ray level appearance, and it can form level and two vertically lines, and then forms an infrared ray right angle contained angle, utilizes this infrared ray right angle contained angle can be used to monitor whether the contained angle between the two adjacent limits of projection image is the right angle.
Step 32: and when the included angle between two adjacent edges of the projected image of the positioning graphic card is a right angle, determining that the shape of the projected image of the positioning graphic card is consistent with that of the wall-mounted hard screen.
Optionally, whether the shape of the projected image of the positioning card is rectangular is determined by determining whether an infrared right-angle included angle formed by the infrared level meter coincides with an included angle between two adjacent sides of the projected image, so that when the included angle between two adjacent sides of the projected image of the positioning card is a right angle, it can be directly determined that the shape of the projected image of the positioning card is consistent with the shape of the wall-mounted hard screen.
According to the projector positioning and mounting method provided by the embodiment of the invention, in the process of adjusting the projector, whether the included angle between two adjacent sides of the projection image of the positioning chart card is a right angle is monitored through the laser level meter, and when the included angle between two adjacent sides of the projection image of the positioning chart card is a right angle, the shape of the projection image of the positioning chart card is determined to be consistent with the shape of the wall-mounted hard screen. According to the technical scheme, the situation that the shape of the projection image of the positioning graphic card is consistent with that of the wall-mounted hard screen is detected through the laser level meter, the monitoring method is simple, convenient and reliable, the efficiency is high, and a foundation is laid for subsequently determining the installation positions of the projector and the wall-mounted hard screen matched with the projector.
