python - 如何在python中使用openCv获取线的坐标

Question

在OpenCV中应用霍夫线法检测线后，我试图获取线的实际坐标。我所说的坐标是指线的端点。这是我用来检测opencv中的行的代码 -

import cv2
import numpy as np
img = cv2.imread('image_name.jpg')
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
edges = cv2.Canny(gray,50,150,apertureSize = 3)
cv2.imshow('edges', edges)
lines = cv2.HoughLinesP(edges,1,np.pi/180,100,minLineLength=100,maxLineGap=10)
for line in lines:
    x1,y1,x2,y2 = line[0]
    cv2.line(img,(x1,y1),(x2,y2),(0,255,0),2)

cv2.imshow('image', img)
k = cv2.waitKey(0)
cv2.destroyAllWindows()
