Abstract:The future complex working environment requires the space manipulator of automatic equipments whichmust have accurate terminal accuracy and space attitude control. However，some reasons，for example，the manipulator assembling gap and the bearing deformation cause deviations between the real positionand the theoretical calculation of the terminal actuators. Therefore，to achieve the trajectory trackingmeasurement of manipulator becomes a will － be solved problem. This paper which combines the charac-teristics of the photo sensitive positioning detector and principles of binocular visual measurement devel-ops a non - contact three － dimensional measuring system based on double PSDs( position sensitive de-tector) which can measure the trace of a space motion target point light source and is used in the angledisplacement and axial displacement test on the machining center and ATC. The job which has beendone is an exploring which includes real － time on － line measurement of motion trajectory of a point tar-get on the complex mechanism，rapid measurement of space position and attitude of robot’s terminal ac-tuator.
