Abstract: In view of problem that it is easy to produce interference between objects with the similar colors while using traditional Camshift algorithm for drill tracking, a drill counting method based on improved Camshift algorithm was proposed. Improved Camshift algorithm was used to capture drill targets real timely, and then drill counting was realized by setting anchor and determining time interval. The improved Camshift algorithm uses template matching method to locate tracking target, intelligently selects appropriate method to extract color histogram, meanwhile introduces particle filters to get exact location of the tracking target in the next frame by combining texture features through certain mechanisms. Experimental results show that the improved algorithm solves the interference problem of similar colors, and is still able to accurately track the target in conditions of partial cover, consequently achieves accurate drill counting.
