采用可编程器件实现图像实时融合系统的控制

Control for image fusion at real time implemented with programmable devices

利用可编程逻辑器件CPLD(Complex Programmable Logic Device)功能灵活、设计简捷的特点,开发了双通道图像像素层实时融合系统的控制单元。两片CPLD中分别实现了帧存控制、总线切换、配准等多种功能,由此简化了整个系统的设计,并且提高了系统的可靠性和稳定性,在红外和可见光双通道融合系统中应用取得了良好效果。

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.
