Abstract: A kind of multispectrum image fusion application system is introduced for detecting and locating ultraviolet corona. A visible CCD and an ultraviolet CCD are used for input in the system. Two CCDs have the same visual field, so the processor can easily fuse two input videos, and then display the realtime fusion image on LCD for user easy to observe and locate corona. RF5 provided from TI Company recently is used as starterware for developing digital signal processing (DSP) applications. Since common elements such as memorymanagement, device drivers, and channel encapsulation arepreconfigured in RF5, developers can focus on their system’s unique needs and achieve better overall productivity. Basic data elements of RF5 are specially discussed, and the software in the image processing board based on them is built up for the system achieving multispectrum image fusion.

Key words: image fusion, ultraviolet corona, RF5, digital signal processing
