想写一个寻找黑色矩形程序出现了如下问题（已解决）
本帖最后由 empty 于 2021-3-23 16:23 编辑请问该如何解决？
内容补充 这让人怎么回，list 列表哪里来的 rect 函数？？？？ 检查返回值的类型吧
你要不就完整的把代码传上来吧

#寻找停机点
black_blobs = img.find_blobs()#寻找黑色区域
max_black = find_max(black_blobs)#寻找最大黑色区域
max_rects = img.find_rects(max_black.rect(),threshold=10000)#寻找区域中的矩形
if max_rects != 0:#找到停机点
img.draw_rectangle(max_rects.rect(),color= (0,255,0),size=80)
max_rects = img.find_rects(max_black.rect(),threshold=10000)#寻找区域中的矩形
把这里的函数和变量全部拿出来调试
tmp = max_black.rect()
max_rects = img.find_rects(tmp,threshold=10000)#寻找区域中的矩形
