Control for image fusion at real time implemented with programmable devices

With the characteristics of flexible function and simple design of Complex Programmable Logic Device (CPLD), the control unit of a double-channel real-time image fusion system in the pixel level is developed. Multiple functions such as frame access control, bus switching and registration are implemented with two pieces of CPLD, respectively. This simplifies the design of the whole system and improves the reliability and stability of the system. Good effects are achieved for the application of the double-channel fusion system in IR and visible bands.
