| Abstract: | A high precision infrared light spot motion analysis and measurement system based on a new type position sensitive detector(PSD)and stereo measurement was developed.This system can detect three dimensional information of moving point rapidly and accurately.Based on it,analysis and calculation were carried out,providing three dimensional coordinates,and also characteristics curves and parameters for concrete applications.This system can be used to detect human body movement for surgical navigation,and so on. |
