如何在Python OpenCV中获取轮廓的x,y位置

我试图从下图中获取轮廓的 x 和 y 位置，但我搞砸了。图片

我只需要找到轮廓的 x 和 y 位置或轮廓的中心。

当我从 GIMP 手动查找它们的位置时，结果将类似于以下内容。

290, 210 982, 190 570, 478

我相信可以用 cv2.findContours 方法来完成，但我现在真的没有想法。

-无关-

我将使用这些值使用 win32api.SetCursorPos((xposition,yposition)) 设置光标位置

Thanks

# ( black and white only image).

        i = i + 1

# Showing the final image. 
cv2.imshow('image2', img2) 

# Exiting the window if 'q' is pressed on the keyboard. 
if cv2.waitKey(0) & 0xFF == ord('q'): 
    cv2.destroyAllWindows()
