如何在Google Colab中使用cap = cv2.VideoCapture(0) [英] How to use cap = cv2.VideoCapture(0) in Google Colab

问题描述

cap = cv2.在Google Colab中执行命令时，VideoCapture(0)没有打开网络摄像机.

cap = cv2.VideoCapture(0) is not opening web camera when executing the command in Google Colab.

推荐答案

由于Colab在您的浏览器中运行，因此您需要使用Web API来访问本地硬件，例如摄像机.

Since Colab is running in your browser, you'll want to use web APIs to access local hardware like a camera.
