Abstract

The invention relates to a thickness measurement platform based on laser beam emission. The thickness measurement platform comprises a data combined device, a low-frequency filtering device, a threshold segmenting device, and a smoothness recognition device, wherein the data combined device is connected with a partition filtering device and is used for receiving each filtering grayscale value of each pixel in each image partition area and combining based on all filtering grayscale values of all pixels in all image partition areas so as to obtain a filtering image corresponding to a HR square image, the low-frequency filtering device is used for filtering low-frequency components in the filtering image so as to acquire a corresponding high-frequency remaining image, the threshold segmentingdevice is connected with the low-frequency filtering device and is used for recognizing each convex pixel in the high-frequency remaining image based on a preset convex brightness threshold range andremoving an isolated point in each convex pixel to obtain and output a convex area, and the smoothness recognition device is used for determining surface smoothness of a glass square based on the area of the convex area. Through adoption of the thickness measurement platform, image processing efficiency and effect are improved.
