Method for correcting RGB GAMMA curve of reinforced display

The invention belongs to the technical field of ruggedized displays, and particularly relates to a ruggedized display RGB GAMMA curve correction method, which comprises the following steps of: respectively acquiring 256-level tristimulus values under red, green and blue pure color pictures; 256-level tristimulus values measured by the three pure color pictures are marked as RX < 0-255 >, RY < 0-255 > and RZ < 0-255 >; gX is 0 to 255, GY is 0 to 255, and GZ is 0 to 255; rX is 0-255, GY is 0-255, BZ is 0-255, RX is 0-255, GY is 0-255, BZ is 0-255, RX is 0-255, GY is 0-255, and BZ is 0-255; calculating required RX and GY according to the required gamma, and recording the required RX and GY and BZ as RXS0-255, GYS0-255 and BZS0-255; according to the RXS0-255, the GYS0-255 and the BZS0-255, table look-up is carried out to obtain the required series of the gamma in the original test data after calculation, and the series are marked as RI0-255, GI0-255 and BI0-255. According to the method, the RX, GY and BZ values o
