红外与可见光传感器是目标跟踪识别系统中常用的两种传感器 ,对这两种传感器图像进行有效的融合能大大提高探测识别的准确性和可靠性。快速准确地实现图像配准是图像融合的前提 ,为此提出了一种基于小波变换的快速算法 ,有利于实时准确地实现图像配准 Infrared and visible light sensors are two commonly used sensors in the target tracking recognition system. The effective fusion of the two sensor images can greatly improve the accuracy and reliability of the detection and recognition. Fast and accurate image registration is the premise of image fusion. For this reason, a fast algorithm based on wavelet transform is proposed, which is good for real-time and accurate image registration
