Embodiment Construction
[0024] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0025] The present invention performs point positioning on the collected LED display screen images, and judges whether the number of LED light points found in the row direction and the column direction is consistent with the actual number of light points on the LED display screen, and if they are consistent, it means that the point positioning is correct , Inconsistency means that the point positioning may be wrong. At this time, the collected LED display image and point positioning results will be displayed for the user to check and change the point positioning. After confirming that the point positioning is correct, continue to correct.
[0026] Specifically, a point-by-point correction method for an LED display proposed by an embodim...

The invention relates to a point positioning method and a point positioning device for LED display screen point-by-point correction. The point positioning device comprises a point positioning and detecting module, a judging module, a result display module, a brightness and chrominance information extracting module and a manual calibration point positioning module, wherein the point positioning and detecting module is used for carrying out point positioning on the image of an LED display screen and detecting the number of lamp points in row and column directions; the judging module is used for judging whether the detected number of the lamp points in the row and column directions is the same as that of actual lamp points of the LED display screen; the result display module is used for displaying the image of the LED display screen and a point positing result for a user to check and displaying a plurality of processing mode options for the user to select so that subsequent processing is carried out to obtain a target point positioning result if the judging result is that the detected number of the lamp points in the row and column directions is different from that of the actual lamp points of the LED display screen; the brightness and chrominance information extracting module is used for extracting the original brightness and chrominance information of the LED lamp points according to the target point positioning result; and the manual calibration point positioning module is used for carrying out manual calibration on the displayed point positioning result based on a human-computer interaction manner so as to obtain the target point positioning result. Therefore, the problem that the result after correction is poor can be solved.
Description
technical field [0001] The invention relates to the technical field of LED display screen correction, in particular to a point positioning method for point-by-point correction of an LED display screen and a point positioning device for point-by-point correction of an LED display screen. Background technique [0002] With the rapid development of LED display, its application is becoming more and more extensive, and people's requirements for its display quality are getting higher and higher. Therefore, the use frequency of LED display point-by-point correction technology is also increasing. The calibration environment is also becoming more and more complicated, for example: there is strong ambient light interference around the LED display screen, there are unstable light sources flickering continuously, strong reflected light, and some LED light points are blocked, etc. These situations may cause If the positioning result of the LED light point is wrong, the original brightnes...
