In 3D vision system, using digital signal processor (DSP) to process 3D visual information in real time, it can improve the speed of processing 3D visual information. In the realization of real-time acquisition and processing system, the data communication between signal acquisition subsystem and DSP and the data transmission between real-time acquisition and processing system and PC are also two important factors affecting the information processing speed of 3D vision system . The system uses dual-port RAM and interrupt mode for data transmission, to achieve the signal acquisition subsystem and DSP, real-time acquisition and processing system and PC parallel processing to improve the entire three-dimensional visual system information processing speed
