cv::Mat img = cv::Mat::zeros(100, 100, CV_8UC3);

python
def simple_full_screen(img, window_name):
cv2.namedWindow(window_name, cv2.WND_PROP_FULLSCREEN)
cv2.moveWindow(window_name, 0,0)
cv2.setWindowProperty(window_name,cv2.WND_PROP_FULLSCREEN,cv2.WINDOW_FULLSCREEN)
cv2.imshow(window_name, img)
cv2.waitKey(0)
效果
/全屏，其实啥也看不出来/
- cv::namedWindow():这个函数的定义，opencv头文件解释
- cv::setWindowProperty()这个函数定义，注意后面两个参数的枚举类型，这个最关键
3、枚举类型，不要用错
