Research on auto-sorting system based on fusion semantics of regular expression

In order to solve the problem of low rate of automatic sorting, according to the identified physical characteristics of the object contour and color and relative distance and the different characteristics of vibration, using the library contains colors. lines. locations and vibration, the match feature of packing box can be constructed by using regular expression. Experiment results showed that the recognition rate was 92.5% under constant perspective and average recognition time was 50.3ms. Compared with the Scale Invariant Feature Transform(SIFT) and Speeded Up Robust Feature(SURF), the proposed method achieved a significant improvement for automatic sorting and identification under constant perspective.
