1. A method for collection and correction of a display unit, comprising the following steps:
step I: placing a camera in front of the display unit to be corrected, such that a center normal of the display unit to be corrected coincides with an optical axis of the camera;
step II: collecting RGB brightness data of the display unit to be corrected to obtain an original brightness matrix; placing a standard brightness plane in front of a lens of the camera, and keeping a center normal of the standard brightness plane coincident with the optical axis of the camera; collecting RGB brightness data of the standard brightness plane, and obtaining a final brightness correction matrix of the camera according to the RGB brightness data of the standard brightness plane;
step III: multiplying the original brightness matrix by the final brightness correction matrix of the camera to obtain a restored real brightness matrix without curved surface distortion of the camera; and
step IV: performing brightness correction on the real brightness matrix to obtain a corrected brightness matrix, thereby completing on-site collection and correction of the display unit.
