Hardware System Design And Implementation Of Real-Time Dual-Spectrum Image Fusion System Based On DSP

In the last 20 years, along with the development of sensor technology and the enhancement of computer's computational ability, the usage of multi-sensors image fusion technology becoms widespread. It was widely used in the fields of military, remote sensing, medicne imaging, network security and so on. For inspect ultraviolet information, a new dual-channel real time video image fusion system based on high performance Digital Signals Processor TMS320DM642 is proposed, use the solar blind filter characteristic of mid-ultraviolet in ultraviolet detection in this paper.In this paper, the demonstration of whole system, the design concept, the component structure and the characteristic of the used core has been described in detail. The characteristic of various functions module, the principia of select chip and the method of design were given, that used for picture gathering, picture processing and fusion, picture storage and display. Introduced the BootLoader design and the FlashBurn transplant method for sure that the system can run independently. Simultaneously the system was optimized by using kinds of optimized design hardware architecture, the algorithm of fast fusion and the system optimization with the embed real-time operating system DSP/BIOS. Finally some questions and the solution were summarized and analyzed, that lay in the system design and debugging. This system could be used in real-time observation of the ultraviolet target signal and the back ground visible light picture, and the picture quality good, the speed of response quick, the range coverage was far.This system had broad application prospect in dual-channel real-time image fusion processing aspect, it can be used in other high speed, complex image signal gathering and processing situation with a few changes.
