Realization of a small real-time DSP-based platform for infrared and visual image fusion

For preserving and processing in real time all salient complementary information of infrared and visual image,a new embedded hardware platform is proposed which is based on TMS320DM642,a fixed-point DSP with video and imaging integration for high performance applications.On this platform many dual-band image fusion algorithms can be programmed.The structure design and work flow of the solution,the function and principle of key components,the calculation of power dissipation and the design of high-speed printed circuit board are presented.The software flow is introduced,which includes the programs of initialization,device driver and fusion application.The results show that the high-performance,small-size and low-power hardware platform can be used in portable stand-alone dual-band image fusion instruments.
