Multi-channel image acquisition preprocessing system based on TMS320DM642

The TMS320DM642 is taken as the core processor for image acquisition, Harris feature points extracting and transmitting data information to PC through network for next-step processing. The computing burden of PC was reduced by reasonably using the capability of DSP. Designed for four-channel image acquisition and feature point extraction for the system and actualized the relevant function. Finally the system provides the image preprocessing information for the 3-D motion capturing course based on stereoscopic vision.
