2、ng the trajectory of planar controllable linkage mechanism based on computervision was presented. Firstly, a visual detection system with camera as the basic part was formed, andthe problem of data lost in the process of image acquiring has been solved. The sequence image ofobject was acquired by th
3、e calibrated camera system, and the trajectory of object was gained by thealgorithms of image processing, object detection and location. The visual detection method for planarcontrollable mechanism has been realized, and the result is satisfactory.Keywords Controllable linkage mechanism, Trajectory
