Detailed Description
The present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
The embodiment of the invention provides a method for correcting an arc-shaped screen, which is suitable for correcting optical characteristics such as brightness or chromaticity of a non-planar display screen by adopting a plurality of cameras and can be realized by a correcting device of the arc-shaped screen. Fig. 1 is a schematic flowchart of a method for correcting an arc-shaped screen according to an embodiment of the present invention, and fig. 2 is a schematic diagram of a positional relationship between the arc-shaped screen and a camera according to an embodiment of the present invention. Referring to fig. 1 and 2, the method for correcting the arc screen includes:
s110, controlling at least two cameras to be placed on a light-emitting surface of the arc-shaped screen according to preset positions; the at least two cameras are equidistant from the arc-shaped screen.
The distance between the camera and the arc screen 10 may be a vertical distance from a side of the camera away from the light exit surface to the light exit surface 11; as shown in fig. 2, the vertical distance from the bottom of the first camera 20-1 to the light-emitting surface 11 is L1, the vertical distance from the bottom of the second camera 20-2 to the light-emitting surface 11 is L2, and the vertical distance from the bottom of the third camera 20-3 to the light-emitting surface 11 is L3; wherein L1= L2= L3. Alternatively, the distance between the camera and the arc-shaped screen 10 may be a vertical distance from the geometric center of the camera to the light emitting surface 11, and the like, as long as the calculation rule of the distance between each camera and the arc-shaped screen 10 is the same. The distance between each camera and the arc-shaped screen 10 is equal, which is equivalent to the fact that the radian of a connecting line of the central points of each camera is equal to the radian of the light-emitting surface 11, so that the resolution of pictures shot by each camera can be ensured to be consistent, and the subsequent data fusion and other processing processes can be simplified; and the shooting parameters such as the aperture of each camera can be uniformly adjusted, so that the correction process is further simplified. For example, multiple cameras may be manually placed by an operator in preset positions; alternatively, the camera may be placed on a moving track, and the controller controls the camera to move to a preset position.
S120, controlling at least two cameras to shoot display pictures of the arc-shaped screen; wherein the area shot by the at least two cameras covers all pixels of the arc-shaped screen.
Wherein, all cameras can be controlled to shoot the display pictures of the arc screen 10 at the same time to shorten the correction time. The areas shot by adjacent cameras may or may not overlap, but the shooting areas of all cameras need to cover all pixels of the arc-shaped screen 10 to ensure the correction effect.
S130, carrying out data fusion processing on image data shot by at least two cameras to obtain actual display data of the arc-shaped screen, and calculating correction parameters of the arc-shaped screen according to the actual display data.
The correction parameters of the arc-shaped screen 10 may include correction data of all pixels in the arc-shaped screen 10, so as to ensure the accuracy of the correction result. The pixels of the arc-shaped screen 10 can be understood as the smallest light-emitting units constituting the arc-shaped screen 10. For example, the arc screen 10 is an LED display screen, and then the LED lamp beads forming the display screen are pixels of the arc screen 10.
In the method for correcting the arc-shaped screen, which is provided by the embodiment of the invention, a multi-camera correction mode is adopted, all the pixels of the arc-shaped screen can be covered by controlling the shooting areas of all the cameras, so that the problems of long time consumption, large error, chromatic aberration, moire fringes and the like in the whole screen after correction caused by repeatedly moving the positions of the cameras during correction of a single camera are effectively avoided, and the correction efficiency and precision are improved. Moreover, the distance between each camera and the arc-shaped screen is set to be equal, so that the resolution of the pictures shot by each camera can be ensured to be consistent, and the processing processes of data fusion and the like can be simplified; and the shooting parameters such as the aperture of each camera can be uniformly adjusted, so that the correction process is further simplified, and the correction time is saved. Therefore, the embodiment of the invention can improve the correction efficiency and the correction precision of the arc screen.
Fig. 3 is a schematic diagram of a positional relationship between an arc-shaped screen and a camera according to another embodiment of the present invention. Fig. 3 can be viewed as a flattened schematic view of the structure of fig. 2 from a bottom-up perspective. Referring to fig. 2 and 3, on the basis of the above embodiments, optionally, there is an overlap between the shooting areas of adjacent cameras; and selecting image data of the middle area of the shot image of each camera for data fusion processing. In the following, referring to fig. 2 and fig. 3, taking three cameras provided in the correction system as an example, the shooting area division of the cameras and the area division of the arc-shaped screen 10 are explained in detail. It should be noted that, the area division of the arc-shaped screen 10 herein means to specify the actual position of the effective area for data fusion processing in the shooting area of each camera on the arc-shaped screen 10, and the arc-shaped screen 10 is not physically divided, and the arc-shaped screen 10 still displays a complete picture as a whole.
In fig. 2, a first camera 20-1, a second camera 20-2 and a third camera 20-3 are arranged in sequence from left to right. In fig. 2, dotted lines represent the edges of the shooting angles of the cameras, and the range between two dotted lines corresponding to the same camera and the light-emitting surface 11 or the intersection point of the extension lines (dot-dash lines) of the light-emitting surface 11 is the shooting area of the camera; the first photographing region A1, the second photographing region A2, and the third photographing region A3 are sequentially from left to right. Referring to fig. 2 and 3, the light emitting surface 11 of the arc-shaped screen 10 is divided into three display sub-regions, namely, a first display sub-region D1, a second display sub-region D2 and a third display sub-region D3 from left to right. The shooting area of each camera correspondingly covers one display sub-area, and the display sub-area is located in the middle area of the shooting area; then, the image data of the middle area of the shot image of each camera is selected for data fusion processing, which is to select and process the image data of the shot image showing the sub-area part in the shot image of each camera. Illustratively, the width of the photographing region may be greater than the width of the display sub-region by 20 pixels or more.
By the arrangement, the edge parts which are acquired more are removed from the data acquired by each camera, so that the integrity of the actual display data of the arc-shaped screen 10 obtained by fusion can be ensured; moreover, the influence of the edge distortion problem of the shot picture of the camera on the actual display data can be reduced, the integral uniformity can be improved, and the correction precision is improved.
With continued reference to fig. 3, on the basis of the above embodiments, optionally, the preset position of the camera may correspond to the central position of the display sub-area; therefore, the accuracy of the picture can be further ensured, and the influence of the picture distortion on the actual display data is reduced; and Moire can be processed uniformly, so that the display effect after correction is optimal. For example, each display sub-region may be formed by equally dividing the light emitting surface 11, that is, the area of each display sub-region is the same, so as to simplify the step of data processing.
It should be noted that, the foregoing embodiments exemplarily show a scheme for performing correction by using three cameras, but the present invention is not limited thereto, and in practical applications, the number of the cameras may be selected according to practical situations, such as the size of the arc-shaped screen.
The above embodiments exemplarily show the arc-shaped screen 10 as an inner arc-shaped display screen, but the invention is not limited thereto. In other embodiments, as shown in fig. 4, the arc-shaped screen 10 may also be an outer arc-shaped display screen, and the camera 20 is still disposed around the light emitting surface 11.

s210, controlling at least two cameras to be placed on a light-emitting surface of the arc-shaped screen according to preset positions; the at least two cameras are equidistant from the arc-shaped screen.
Wherein this step corresponds to a preliminary determination of the camera position. If the arc screen is a large LED display screen, the initial distance between the camera and the arc screen can be preliminarily determined according to empirical values, for example, between 8 and 15 meters.
And S220, controlling all pixels in the arc-shaped screen to display the same set color.
In a color display screen, each pixel can usually display multiple colors; the embodiment can control all the pixels in the arc-shaped screen to display the same set color in one correction cycle to obtain the correction data of all the pixels for the set color; and different set colors are set in a plurality of correction cycles to obtain correction data for all pixels for the different set colors. Illustratively, the set colors include red, blue, and green.

Whether the shot picture is qualified or not can be judged according to the number of pixels of the shot picture of the camera occupied by a single pixel in the arc-shaped screen and/or the brightness of the shot picture. For example, if a single pixel in the arc screen occupies too few pixels of the captured image of the camera, such as less than 30 pixels, the captured image may be considered to be rejected.
And S250, adjusting the shooting parameters of the camera according to the shooting picture.
Wherein, the shooting parameter of camera includes: aperture and/or exposure time. When the shot picture is unqualified, the aperture and/or the exposure time of the camera can be adjusted according to the number of pixels of the shot picture of the camera occupied by the single pixel in the arc-shaped screen and/or the brightness of the shot picture. For example, the exposure time is reduced when the photographed picture is too bright.
S260, judging whether the adjustment times of the shooting parameters exceed a threshold value; if so, perform S270, otherwise perform S230.
If the shooting parameters are adjusted for multiple times, the shot picture is still not qualified, the adjustment of the shooting parameters can be considered invalid, and the distance between the camera and the arc-shaped screen can be adjusted.
And S270, adjusting the distance between the at least two cameras and the arc-shaped screen, and resetting the adjustment times of the shooting parameters.
Wherein, each camera can wholly adjust, and in the adjustment process, the distance that keeps each camera and arc screen is unanimous throughout. And, in the adjusting process, the maximum shooting angle of view (such as the maximum shooting angle of view Arc in fig. 4) of the camera can be always controlled to be less than 120 ° to ensure the quality of the shot picture. At this time, the adjustment times of the shooting parameters are reset, which is equivalent to zero clearing of the adjustment times, so that the adjustment of the next round can be smoothly performed after the distance is changed.
And S280, carrying out data fusion processing on image data shot by at least two cameras to obtain actual display data of the arc-shaped screen, and calculating correction parameters of the arc-shaped screen according to the actual display data.
And S290, correcting the arc screen according to the correction parameters, and controlling the arc screen to display the corrected picture.
S2A0, judging whether the corrected display picture meets the requirements or not; if yes, executing S2B0; otherwise, S220 is performed.
Wherein the step is actually determining whether the corrected picture is an expected display picture; specifically, the corrected actual display frame may be compared with the expected display frame, and if the error is within the allowable range, the corrected frame is considered to be the expected display frame, which meets the requirement. And if the corrected display picture does not meet the requirements, performing a new round of correction on the arc-shaped screen.
And S2B0, storing the correction parameters.
The correction parameters can be saved in a memory in a processor configured in the arc screen so as to be called when the processor controls the arc screen to normally display the picture.
