Acupoint Positioning and Tracking based on Template Matching
Guangyue Du · Bulletin of Science and Technology · 2011
As the movements of the body,it is necessary to get the coordinate acupoint and tracking acupoint when the massage robot is working.An acupoint positioned method based on template matching is proposed,which is combined with human back features and the characteristics of movement.First,making use of fast template matching algorithm to acquire the center coordinates of red artificial mark which put on human back.Second,the world coordinates of acupoint can be get through camera calibration method.Third,camera will track the artificial watchpoint on neck and calculate motion vector which would be added acupoint coordinate.And a cupoint visual tracking can be achieved.Experimental results show that the algorithm has more stability.Template matching is better than HOUGH algorithm in the aspect of error detection.
