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)
