在OpenCV中绘制平面的法向量

import cv2
import numpy as np

image = np.zeros((400, 400, 3), dtype=np.uint8)

start_point = (100, 100)
end_point = (300, 300)

normal_vector = np.array([end_point[1] - start_point[1], start_point[0] - end_point[0]])

cv2.arrowedLine(image, start_point, (start_point[0] + normal_vector[0], start_point[1] + normal_vector[1]), (0, 255, 0), 2)

cv2.imshow("Plane with Normal Vector", image)
cv2.waitKey(0)
cv2.destroyAllWindows()
