如何使用opencv或python检测两条相交(交叉)的曲线？

import cv2
import numpy as np

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

lines = cv2.HoughLinesP(edges, 1, np.pi/180, threshold=100, minLineLength=20, maxLineGap=10)

intersections = []
for i in range(len(lines)):
    for j in range(i+1, len(lines)):
        line1 = lines[i][0]
        line2 = lines[j][0]
        x1, y1, x2, y2 = line1
        x3, y3, x4, y4 = line2
        intersection = cv2.line(image, (x1, y1), (x2, y2), (0, 255, 0), 2)
        intersections.append(intersection)

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