Abstract

A real time processing system and a white line following algorithm used for high speed ALV navigation on structural road are described in this paper. The real time image processing system includes a color video camera, several processors with special functions and a general purpose processing unit based on TMS 320C30 microprocessor. Each special processor performs a standard image processing operation such as image thresholding, color look-up-table, histogram statistics, morphology operation, and so on. A general purpose unit performs some algorithms at high speed. There are two buses in the system. Each processor can communicate with each other through image data bus and communicate with the host computer through extended PC-bus as well. The system is more convenient for programming and can
