如何使用OpenCV python绘制平行于最小面积矩形宽度的直线连接相对轮廓点

import cv2
import numpy as np

image = cv2.imread('image.jpg')
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
blur = cv2.GaussianBlur(gray, (5, 5), 0)
edges = cv2.Canny(blur, 50, 150)

contours, _ = cv2.findContours(edges, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)

for contour in contours:
    rect = cv2.minAreaRect(contour)
    box = cv2.boxPoints(rect)
    box = np.int0(box)

width = np.linalg.norm(box[0] - box[1])

start_point = (int(box[0][0]), int(box[0][1] - width))
end_point = (int(box[1][0]), int(box[1][1] - width))

cv2.line(image, start_point, end_point, (0, 255, 0), 2)

cv2.imshow('Result', image)
cv2.waitKey(0)
cv2.destroyAllWindows()
