Screen region division method considering visual characteristics

The invention provides a screen region division method and system considering visual characteristics, and belongs to the technical field of alarm devices, and the method specifically comprises the steps: obtaining coordinate distances between the center positions of different sub-regions and the center position of a screen, determining comprehensive evaluation factors of the different sub-regions by combining the region uniformity of the different sub-regions and the texture features of the test image, and determining the number of secondary division regions of the different sub-regions through the comprehensive evaluation factors when secondary region division of the sub-regions needs to be carried out based on the comprehensive evaluation factors; and the chromaticity uniformity of the screen is determined according to the feature points of the different secondary division regions and the comprehensive evaluation factors, so that accurate evaluation of the chromaticity uniformity is realized. 本发明提供一种考虑视觉特性的
