      @kidswong999 程序只能识别第一位的0，是逻辑错误吗

      0

    • 你的逻辑很奇怪，遍历区域直接for循环就行。那个a加来加去没意义。

      rois = [(5, 50, 25, 35),(30, 50, 25, 35),(55, 50, 25, 35),(80, 50, 25, 35),(105, 50, 25, 35)]
for roi in rois:
    for t in templates:
         template = image.Image(t)
         r = img.find_template(template, 0.70, step=4, search=SEARCH_EX, roi=roi)
         if r:
             img.draw_rectangle(r)
             print(t)
