Abstract

In order to realize the automatic registering system of rotary screen printing based on smart camera, this paper proposes the color printing images segmentation technology based on Mean Shift algorithm and the block matching algorithm based on Harris corner detection. The extended form of the Mean Shift algorithm is used in the segmentation of printing images, and the experiments show that the algorithm is good for the segmentation of printing images. Each chromaticity region is extracted from the segmented standard image,and the feature points on each region are detected by Harris operator. With these feature points as centers, select the standard matching blocks, and find the best matching blocks in the dealt image caught in real time to calculate the register error. The algorithms are proved to be feasible by simulations and experiments, which lays foundation for the closed-loop control of online register detection.
