如何通过Qt c++ gui应用程序访问USB摄像头

Question

I am new to Qt GUI development. I have installed Qt GUI on windows platform. I need to setup a Qt C++ based GUI application to run connected USB camera. I tried to find out the related example but mostly based on webcam application. Is there any suggested example for accessing USB camera via Qt C++ GUI, I can go through?

Answer 1

There is no essential difference between "webcam" and "usb camera". A webcam is a video camera that feeds or streams an image or video in real time. This means that your USB camera can be a webcam if it supports such a function.

To accomplish your task, use the qt documentation and it's perfect examples, like this camera example .
