python边缘检测透视变换

在Python中实现边缘检测和透视变换的代码可以如下所示：

import cv2
import numpy as np

# 读取原始图像
img = cv2.imread("image.jpg")

# 进行边缘检测
edges = cv2.Canny(img, 100, 200)

# 定义原始图像四个坐标点
pts1 = np.float32([[141, 131], [480, 159], [493, 630], [64, 601]])

# 定义变换后图像四个坐标点
pts2 = np.float32([[0, 0], [0, img.shape<span class="em">1</span><span class="em">2</span><span class="em">3</span>
