摘要：
In order to realize real-time image fusion and improve fusion rate, an infrared and low-light image fusion algorithm based on wavelet transform is proposed, and an uncooled infrared and ICMOS image fusion system based on FPGA is developed on this paper. The system has completed image acquisition, image fusion and video output. Based on the analysis of the implementation of each part, this paper focuses on the study of image fusion algorithm based on FPGA. This algorithm greatly reduces the storage resources. At the same time, the fusion rule based on local energy is adopted to greatly improve the fusion effect of low-frequency images. The system can better retain the characteristics of infrared and low-light images which realize fusion imaging under 9* 10(-4)lx illumination. The experimental results show that the image processed by the proposed image fusion algorithm has good brightness characteristics, high contrast and large amount of information.
