TM_CCOEFF_NORMED是一种模板匹配方法,用于计算归一化相关系数。在使用这种方法时,通过计算模板与目标图像的相关性系数来确定匹配程度。相关性系数的取值范围在-1到1之间,值越接近1表示匹配程度越高。\[3\]
在代码中,使用cv2.matchTemplate函数进行模板匹配,并将方法参数设置为cv2.TM_CCOEFF_NORMED。然后使用cv2.minMaxLoc函数找到结果的最小值和最大值的位置,通过判断方法是否为cv2.TM_SQDIFF或cv2.TM_SQDIFF_NORMED来确定最小值的位置。最后,使用cv2.rectangle函数在目标图像上绘制矩形框来标记匹配的位置。\[3\]
