我试图使用我的计算机上的摄像头实时捕获图像。 我使用虚拟盒子运行Ubuntu,并且我知道我需要设置USB设置才能使用网络摄像头,但是我仍然需要安装网络摄像头驱动程序吗?如果是的,我该怎么做!opencv视频捕获和虚拟机上的摄像头访问
我安装 的VirtualBox 5.0.6 的Ubuntu 14.04.3
,我运行Windows 10的机器
这里是我运行代码,我收到“错误:无法访问相机!” ..
请你帮忙!
// Get access to the webcam.
void initWebcam(VideoCapture &videoCapture, int cameraNumber)
{
// Get access to the default camera.
try {
videoCapture.open(cameraNumber);
} catch (Exception &e) {}
if (!videoCapture.isOpened()) {
cerr << "ERROR: Could not access the camera!" << endl;
exit(1);
}
cout << "Loaded camera " << cameraNumber << "." << endl;
}
int main(int argc, char** argv)
{
const int DESIRED_CAMERA_WIDTH = 640;
const int DESIRED_CAMERA_HEIGHT = 480;
int cameraNumber = 0;
// Get access to the camera.
VideoCapture camera;
initWebcam(camera, cameraNumber);
camera.set(CV_CAP_PROP_FRAME_WIDTH, DESIRED_CAMERA_WIDTH);
camera.set(CV_CAP_PROP_FRAME_HEIGHT, DESIRED_CAMERA_HEIGHT);
while (true) {
// Grab the next camera frame. Note that you can't modify camera frames.
Mat cameraFrame;
camera >> cameraFrame;
if(cameraFrame.empty()) {
cerr << "ERROR: Couldn't grab the next camera frame." << endl;
exit(1);
}
Mat displayedFrame = Mat(cameraFrame.size(), CV_8UC3);
// DO SOME PROCESSING
return 0;
}
这应该回答。我也有同样的问题。 – userXktape
