rect = cv2. minAreaRect (cnt) box = cv2. boxPoints (rect) box = np. int0 (box) im = cv2. drawContours (im,[box], 0,(0, 0, 255), 2) 同一画像上に二つの外接矩形を描画します．緑の長方形が外接矩形，赤い長方形が回転を考慮した外接矩形にです． Here are the examples of the python api cv2.MORPH_RECT taken from open source projects. By voting up you can indicate which examples are most useful and appropriate.

Though, in your algorithms you may count x and y from the bottom-left corner. Rectangle width and height. desenha um retângulo em torno dessa área usando cv2.minAreaRect ; A ideia era que o cv2.minAreaRect também retornasse o ângulo, o que eu poderia usar para compensar a imagem. No entanto, no meu caso, é de -90 °. Você pode ver uma amostra de imagem de input . Você pode ver o resultado que recebo .

This is a default interpretation of Rect_::x and Rect_::y in OpenCV. Though, in your algorithms you may count x and y from the bottom-left corner. Rectangle width and height. Here, bounding rectangle is drawn with minimum area, so it considers the rotation also. The function used is cv.minAreaRect(). It returns a Box2D structure which contains following details - ( center (x,y), (width, height), angle of rotation ).
