Abstract :
In three-dimensional laser light scanning in Full Degrees of Freedom, the laser stripe profile information of some images is damaged and can´t be detected normally as result of the scanning unit dithering and variations of ambient light. Aiming at this problem, a novel laser image evaluation method is presented. The mathematical model is built to evaluate contrast, luminance and ambiguity respectively. According to weight factor of each evaluation sub-item, the total evaluation score is obtained, and is the basis for whether to process the image or not. Experiment show that this method is consistent with the result of laser stripe profile detection.
