Abstract

The invention discloses a color brightness recognition method and device, electronic equipment and a computer storage medium, relates to the technical field of automatic detection, and aims to solve the problems of low recognition precision and low recognition efficiency. The method comprises the following steps: collecting a sampling image of to-be-tested equipment placed in a closed box; carrying out white balance adjustment on the sampling image to obtain a sampling image after white balance processing; filtering the sampled image after white balance processing, and calculating the main color of the sampled image through a PCA algorithm; and storing or reporting the main color of the sampled image.

Description

technical field [0001] The invention relates to the technical field of automatic detection, in particular to a color brightness recognition method, device, equipment and medium. Background technique [0002] During the testing and calibration of smart colored lights, their color and brightness need to be precisely adjusted. The traditional method is to adjust by directly observing the color and brightness of the lamp with the human eye. Although the traditional method is simple to implement, it is inefficient and not suitable for large-scale testing. And because each person's sensitivity to color and brightness is different, and the color and brightness of the lamp are also easily affected by external environmental factors (such as external light, etc.), the recognition accuracy is low, resulting in unstable subsequent calibration results. Not very accurate. [0003] Aiming at the problems of low recognition efficiency and low recognition accuracy of traditional methods, ...
