我正在尝试使用openCV在图像中的对象周围绘制最小边界矩形,
cv2.minAreaRect返回正确大小的矩形,但其方向已关闭
以下是我的代码片段
以下屏幕截图显示了我正在处理的图像
在下一个屏幕截图中,它显示带有检测到的边框的图像
根据此处链接的opencv文档:https://docs.opencv.org/3.4/dd/d49/tutorial_py_contour_features.html
这应该工作 
np.where()以正常数组索引(行,列)的顺序返回内容,但是OpenCV期望点以(x,y)顺序与(行,列)相反。这样的效果是您正在翻转图像对角线周围的点。
只需交换两列即可反转点。更好的是对变量更明确,而不是一味地做所有事情:
y,x = np.where(二进制== 0)
坐标= np.column_stack((x,y))
