High-Speed Aerial Image Processing System based on DSP

摘要

This paper introduces a high-speed parallel system based on DSP to process aerial image. The system is of the master-slave architecture. The master system is composed of general computer. Its slave system based on high speed DSP TMS320C6201 array can process real time aerial image concurrently. The data communicates between the master system and the slave system through bus interface. In this thesis, on the basis of the fundamental characters of digital image processing, we adopt domain decomposition method suiting digital image processing. The mode can parallelize serial digital image-processing algorithms which process digital images on spatial domain. This algorithm applies in many image algorithms and can be realized easily. At the same time it ensures every DSP load balance in the course of processing aerial image. Experiments show the system is effective, simple and steady.
