opencv-python调用摄像头调节分辨率

在使用OpenCV-Python调用摄像头时,可以通过设置摄像头的分辨率来调节图像的质量。要设置摄像头的分辨率,可以使用OpenCV库中的`cv2.VideoCapture()`函数打开摄像头,并在打开摄像头后使用`cv2.VideoCapture().set()`方法来设置分辨率。例如,使用`cv2.VideoCapture(0).set(cv2.CAP_PROP_FRAME_WIDTH, 1280)`和`cv2.VideoCapture(0).set(cv2.CAP_PROP_FRAME_HEIGHT, 720)`来分别设置摄像头的宽度和高度为1280x720像素。这样就可以调节摄像头的分辨率了。你也可以使用fswebcam来调整摄像头的分辨率。安装fswebcam后,可以使用命令`fswebcam --no-banner -r 1280x720 -q img.jpg`来保存一张分辨率为1280x720的图片。这样就可以验证摄像头的分辨率是否调整成功了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
