Python语言读取图像

import cv2
import numpy as np

width = 640  # 图像宽度
height = 480  # 图像高度
channels = 3  # 颜色通道数
imgEmpty = np.empty((height, width, channels), np.uint8)  # 创建空白数组
imgBlack = np.zeros((height, width, channels), np.uint8)  # 创建黑色图像 RGB=0
imgWhite = np.ones((height, width, channels), np.uint8) * 255  # 创建白色图像 RGB=255

# 读取图像文件
image = cv2.imread('F:\\MYOpenCV\\xihuduanqiao.jpg')

if image is None:
    print('Image not found!!!')
else:
    # 显示图像
    cv2.imshow('Loaded Image', image)
    cv2.waitKey()
    cv2.destroyAllWindows()
