openvino Can't find the camera cam

woff

在openvino 下用CAM時，下了指令

1. interactive_face_detection_demo.exe -i cam -m C:\Program Files (x86)\Intel\openvino_2021.4.689\deployment_tools\open_model_zoo\tools\downloader\intel\face-detection-adas-0001\FP32\face-detection-adas-0001.xml

複製代碼

出現錯誤訊息

1. [ ERROR ] Can't find the image by cam
   
2. Can't find the dir by cam
   
3. Can't open the video from cam
   
4. Can't find the camera cam

複製代碼

在WIN10下，攝影機是有編號的指令改成

1. interactive_face_detection_demo.exe -i 0 -m C:\Program Files (x86)\Intel\openvino_2021.4.689\deployment_tools\open_model_zoo\tools\downloader\intel\face-detection-adas-0001\FP32\face-detection-adas-0001.xml

複製代碼

這樣就可以了
