摘　　要：利用中紫外区的"日盲特性",提出一种以高性能数字信号处理器TMS320DM642为核心的双通道实时图像融合处理系统。本系统先通过分光、图像增强和光谱转换实现紫外和可见光信号的采集。然后将紫外信号和可见光背景信号转化为数字信号,并进行融合处理以实现紫外信号的检测与定位。此系统在电力系统电晕检测及森林火灾等紫外信号检测的场合有远大的应用前景。For making use of the solar blind filter characteristic of mid - ultraviolet in ultraviolet detection, a new dual -channel real -time video image fusion system based on high performance Digital Signals Processor TMS320DM642 is introduced. The system can realize UV singal grabbing through UV filter and image intensified device at first. And then UV singal and visualsingal is transformed into digital singal and fused for UV detection and orientation through high integrated encoder, decoder and DSP used for video signal processing. The system will be used widely in public security,electric power,fire of forest and so on.
