In view of the present problem of the LED display brightness not uniformity, the text puts forward a kind of LED light assembly angle automatic detection system. First, make use of stepping motor drive the LED display module rotation. In the process of LED rotation, use CCD camera get each image of LED display module with Angles of each step; And then by using the template matching principle pinpoint positions of leds in LED display module. Finally, detect the brightness of the led, and according to the step motor’s stepping Angles to calculate the deflection Angles of leds.
