Embedded Horopter Machine Vision Platform Based on DM642

This paper introduces the structure and key technology of embedded horoper stereo vision platform based on DM642 and video driver chip implementation, This system takes full advantage of the excellent performance in image processing chip- DM642. It gets over the shortcomings such as the poor real-time image processing system to handle low precision, low confiden- tiality and poor scalability of the traditional PC-based data acquisition card. The DSP takes the main responsibility of image processing work and can communicate with PC via various channels and thus reduce the burden on the computer. The hardware of the platform is designed by using the design idea of object-oriented software for hardware reuse.
