Abstract :
A multi-channel image superimposition system is designed in this paper. It can superimpose white-light image on infrared thermal image to generate mixture image. The system is realized on a FPGA chip and is mainly composed of multi-channel DMA controller and image superimposition module. Multi-channel DMA controller can realize data exchange between image superimpositon module and memory independent of vehicle-loaded CPU. Image superimposition module adopts Alpha channel mixture algrithm to mix two-channel images. Equations of algrithm are modified to forms that can be easily designed on a FPGA chip. Due to using programmable chips and parallel processing technology, the system has high integration, good maintenance, quick image processing speed and strong real-time capability.
