摘　　要：针对相关跟踪算法,研究了灰度畸变对它的影响。首先,对相关算法进行了分析,选取归一化互相关积算法作为研究对象。然后,选取调制对比度描述灰度畸变的剧烈程度,分析了引起对比度变化的因素。再次,利用M atlab软件仿真计算,详细分析了对比度、相关度和图像畸变面积之间的关系。最后,实验证明了理论分析的正确性。The effect of grayscale distortion on the correlation tracking algorithm was studied. First, the principle of the correlation tracking algorithm was analyzed, and the normalized cross-correlation algorithm was taken as the research object. Then, the modulation contrast was selected to describe the intensity of grayscale distortion, and the factors of the contrast change were analyzed. Finally, the relationship among contrast, correlation and grayscale distortion area were analyzed in detail through simulation with Matlab. Experimental result proved the correctness of the theoretical analysis.
