In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example one
As shown in fig. 1, an embodiment of the present invention provides a method for correcting an LED display screen, where the detection method includes the following steps:
step S110: and respectively carrying out image acquisition on the LED display screen in a left visual area, a front visual area and a right visual area of the LED display screen so as to obtain a corresponding left image, a front image and a right image.
Specifically, to ensure the display consistency of the LED display screen at multiple viewing angles, after the LED display screen is assembled, corresponding correction operations are performed on the left-view picture, the front-view picture and the right-view picture of the LED display screen, respectively, and the first step of performing the corresponding correction operations is to perform corresponding image acquisition, that is, image acquisition is performed on the LED display screen at the left-side visible area, the front-side visible area and the right-side visible area of the LED display screen, respectively, so as to obtain the corresponding left-side image, the front-side image and the right-side image, as shown in fig. 2, the specific process includes:
step S111: and carrying out image acquisition on the LED display screen in a left visual area of the LED display screen through image acquisition equipment to obtain a left image.
Step S112: and carrying out image acquisition on the LED display screen through image acquisition equipment in a front visible area of the LED display screen to obtain a front image.
Step S113: and carrying out image acquisition on the LED display screen in a right visible area of the LED display screen through image acquisition equipment to obtain a right image.
The above-mentioned left visible area of the LED display screen specifically refers to an area where the LED display screen is observed within the left visible area, so that if a left image is desired, the image capturing device needs to be placed within the left visible angle range of the LED display screen to capture the image of the LED display screen, so as to obtain the left image. Similarly, the front-side visible area of the LED display screen mentioned above refers to an area where the LED display screen is viewed directly opposite to the normal of the LED display screen, so that if a front-side image is desired, the image capturing device needs to be placed in a range where the normal of the LED display screen is directly opposite to the LED display screen to capture the image of the LED display screen, so as to obtain the front-side image. Similarly, the right visible area of the LED display screen mentioned above refers to an area where the LED display screen is observed within the right visible area, so that if a right image is desired, the image capturing device needs to be placed within the right visible angle of the LED display screen to capture the image of the LED display screen, so as to obtain the right image.
Step S120: and respectively carrying out primary correction processing on the left-view picture, the front-view picture and the right-view picture of the LED display screen based on the left-side image, the front-side image and the right-side image, and obtaining a corresponding left-side correction coefficient, a front-side correction coefficient and a right-side correction coefficient.
Specifically, after the left image, the front image, and the right image are obtained through the above steps, the left view frame, the front view frame, and the right view frame of the LED display screen may be subjected to the primary correction processing based on the left image, the front image, and the right image, and the corresponding left correction coefficient, front correction coefficient, and right correction coefficient are obtained, as shown in fig. 3, and the specific process is as follows:
step S121: and carrying out primary correction processing on a left view picture of the LED display screen based on the left image, and obtaining a left correction coefficient.
Step S122: performing primary correction processing on the front-view picture of the LED display screen based on the front-view image, and obtaining a front-view correction coefficient;
step S123: and carrying out primary correction processing on a right view picture of the LED display screen based on the right image, and obtaining a right correction coefficient.
When the left-view picture of the LED display screen is primarily corrected based on the left-side image, the pixels in the left-view picture of the LED display screen are primarily corrected based on the left-side image with reference to the preset target value, and a left-side correction coefficient is obtained. Similarly, when the front-view image of the LED display screen is subjected to the primary correction processing based on the front-view image, the primary correction processing is performed on each pixel point in the front-view image of the LED display screen based on the front-view image with reference to the preset target value, so as to obtain the front-view correction coefficient. Similarly, when the primary correction processing is performed on the right-view image of the LED display screen based on the right-side image, the primary correction processing is performed on each pixel point in the right-view image of the LED display screen based on the right-side image with reference to the preset target value, and a right-side correction coefficient is obtained. The preset target values refer to brightness, color temperature and color coordinate values required after correction in an ideal state; after the image acquisition equipment acquires the corresponding image, the computer system can identify the brightness of each pixel point, then the brightness is compared with a preset target value, the difference value is analyzed, and then the adjustment is carried out to obtain the corresponding correction coefficient.
Step S130: and calculating to obtain a first average correction coefficient according to the left correction coefficient and the right correction coefficient, and respectively carrying out secondary correction processing on the left-view picture and the right-view picture through the first average correction coefficient.
Specifically, after the left-view picture, the front-view picture and the right-view picture are respectively subjected to primary correction processing through the steps of the method, and corresponding left-side correction coefficients, front-side correction coefficients and right-side correction coefficients are obtained, because the primary correction processing is performed independently at each azimuth viewing angle, slight deviation is inevitable, and secondary correction processing needs to be performed on the left-view picture and the right-view picture based on the left-side correction coefficients, the front-side correction coefficients and the right-side correction coefficients in order to further ensure the display consistency of the multi-azimuth viewing angles of the LED display screen. Preferably, a first average correction coefficient is obtained by calculating according to the left correction coefficient and the right correction coefficient, and the second correction processing is performed on the left-view picture and the right-view picture respectively through the first average correction coefficient, as shown in fig. 4, the specific process is as follows:
step S131: and averaging the left correction coefficient and the right correction coefficient to obtain a first average correction coefficient.
Step S132: and respectively carrying out secondary correction processing on each pixel point in the left-view picture and each pixel point in the right-view picture through the first mean correction coefficient.
The average value of the left correction coefficient and the right correction coefficient can be obtained by adding and summing the left correction coefficient and the right correction coefficient and dividing by 2, so that the first average value correction coefficient is obtained. And then, carrying out secondary correction processing on each pixel point in the left-view picture and each pixel point in the right-view picture respectively by using the first mean correction coefficient, so that the deviation caused by independent processing of each azimuth viewing angle in the primary correction processing can be avoided, the difference between the left side and the right side is reduced, and the display consistency of the left-view picture and the right-view picture of the LED display screen is ensured.
Step S140: and calculating to obtain a second average correction coefficient according to the first average correction coefficient and the front correction coefficient, and performing secondary correction processing on the front view picture through the second average correction coefficient.
Specifically, as in the above steps, in order to further ensure the display consistency of the multi-directional viewing angles of the LED display, the secondary correction process is performed on the viewing frame based on the left correction coefficient, the front correction coefficient, and the right correction coefficient. Preferably, a second mean correction coefficient is calculated according to the first mean correction coefficient and the front correction coefficient, and the second mean correction coefficient is used to perform the second correction processing on the front view image, as shown in fig. 5, the specific process is as follows:
step S141: and averaging the first average value correction coefficient and the front face correction coefficient to obtain a second average value correction coefficient.
Step S142: and carrying out secondary correction processing on each pixel point in the positive-view picture through the second mean correction coefficient.
The first average correction coefficient and the front correction coefficient are added and summed and then divided by 2, so that the average value of the first average correction coefficient and the front correction coefficient can be obtained, and a second average correction coefficient is obtained. And then, secondary correction processing is carried out on each pixel point in the front-view picture by using the second mean correction coefficient, so that the deviation caused by independent visual angles of all directions in primary correction processing can be avoided, the difference among all directions is reduced, and the display consistency of a left-view picture, a front-view picture and a right-view picture of the LED display screen is ensured.
