在Python OpenCV中检测线条而不应用高斯模糊

import cv2
import numpy as np

image = cv2.imread('image.jpg')
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)

edges = cv2.Canny(gray, threshold1, threshold2)

lines = cv2.HoughLinesP(edges, rho, theta, threshold, minLineLength, maxLineGap)

for line in lines:
    x1, y1, x2, y2 = line[0]
    cv2.line(image, (x1, y1), (x2, y2), (0, 255, 0), 2)

cv2.imshow('Detected Lines', image)
cv2.waitKey(0)
cv2.destroyAllWindows()
