我正在使用RPi-cam-web-interface,并且从pi照相机中,rasperry pi不断将图像扔到链接上,我想在计算机上使用opencv处理该图像。
这是senddex建议使用的link软件。
这是senddex视频的link。
流URL以从中提取图像 看起来像是要从中提取图像的URL。
答案 0 :(得分:0)
您是否尝试过如下所示在VideoCapture中传递您的网址:
cap = cv2.VideoCapture()
cap.opne("Your_URL")
答案 1 :(得分:0)
如果您可以将RPI链接放入VLC播放器中,则该链接应适用于此小部件。您可以使用cv2.videoCapture()
从URL流式传输。将rtsp_stream_link
更改为您的RPI网址。
