Abstract

The invention discloses a brightness and chrominance data extraction method and device, and a computer readable storage medium, and the method comprises the steps: correcting initial image data corresponding to a target display panel, so as to overcome the distortion caused by a photographing angle and the reasons of a camera, and precisely locate a display region from a photographed image; further obtaining the coordinate positions of the effective light-emitting units by accurately detecting and positioning the light-emitting units in the display area; and finally, performing corresponding calculation through the standard brightness and chrominance data and the effective bright spot coordinates to obtain respective brightness and chrominance data of all the light emitting units, so that automatic and efficient extraction of the brightness and chrominance data is realized, and tedious point-by-point brightness and chrominance data test operation is avoided. Therefore, the technical problem of low extraction efficiency of the brightness and chrominance data in an existing correction mode is solved. The method is easy to integrate on an industrial production line, data extraction is rapid and accurate, and industrial full-automatic processing is convenient to realize.

Description

technical field [0001] The present invention relates to the technical field of display image processing, and in particular, to a method, device and computer-readable storage medium for extracting luminance and chrominance data. Background technique [0002] The LED display is composed of numerous LED lights arranged in a matrix. Different LED lights will cause differences in the brightness and chromaticity of the LED display due to their luminous characteristics, brightness attenuation and heat dissipation, which will affect the LED display. The viewing quality of the display screen's display. [0003] In order to improve the uniformity and color fidelity of LED display brightness and chromaticity, point-by-point correction technology is the most effective method currently available. There are generally two existing calibration methods. The first is to obtain the real brightness and color information of each LED lamp bead in the LED display screen, and specifically measure ...
