point_size = 1

point_color = (0, 0, 255) # BGR

thickness = 4 # 可以为 0 、4、8

# 要画的点的坐标

points_list = [(160, 160), (136, 160), (150, 200), (200, 180), (120, 150), (145, 180)]

for point in points_list:

　　cv.circle(img, point, point_size, point_color, thickness)

# 画圆，圆心为：(160, 160)，半径为：60，颜色为：point_color，实心线

cv.circle(img, (160, 160), 60, point_color, 0)
