Research on Location of Pulse-Diagnosis Point Based on Image Processing

Intelligent pulse diagnosis robot is a research direction of intelligent medical treatment, many researchers in China and abroad have devoted themselves to promoting the modernization of Pulse-diagnosis with the development of modern science and technology. Before the robotic arm reaches the position of pulse diagnosis, the robot needs to detect the initial position of pulse diagnosis point accurately if it wants to complete autonomous localization. In order to detect the position of Pulse-diagnosis point, a method of Pulse-diagnosis point location based on image processing is proposed in this paper. The corresponding position and posture transformation relation is obtained by establishing coordinate system among image acquisition device, robotic arm and finger. The positioning method of “inch”, “close” and “ruler” is proposed, and the recognition of pulse diagnosis point is realized by using gray scale transformation, middle finger positioning algorithm, palm-arm pattern detection algorithm and image coordinate transformation. The results showed that above methods could be used to locate the Pulse-diagnosis point and prepare for the intelligent pulse diagnosis process.
