我刚刚安装了带有OpenNI和Primesense Sensor的OpenCV 2.4.7,可以在以下构建信息中看到.
我在从VideoCapture对象获取图像时遇到问题.例如,如果我运行openni_capture示例,则会显示“无法获取图像”.但是我得到有关深度和RGB摄像机的信息,所以我认为我已经正确打开了VideoCapture对象,但是当它尝试捕获图像时,grab函数返回0.
我正在使用Asus Xtion Pro Live,并且OpenNI和Sensor可以正常运行,因为我可以运行诸如NiViewer之类的示例.
我希望对这个问题有所帮助.
谢谢！

我实例化了视频捕获,并尝试捕获图像,如下所示：
VideoCapture capture;
capture.open(CV_CAP_OPENNI);
if ( !capture.isOpened() )
{
cout << "Error opening capture" << endl;
return -1;
}
if( !capture.grab() )
{
cout << "Can not grab image" << endl;
}
解决方法:
根据您的代码,我的猜测是将使用kinect openni驱动程序而不是华硕openni驱动程序
这个怎么样：
VideoCapture capture;
capture.open(CV_CAP_OPENNI_ASUS);
if ( !capture.isOpened() )
{
cout << "Error opening capture" << endl;
return -1;
}
if( !capture.grab() )
{
cout << "Can not grab image" << endl;
}
过去我曾经在opencv上使用过两个asus xtion pro传感器,可以看到我的测试code here.
另外,这些是highui types header中的值,并带有注释：
CV_CAP_OPENNI =900, // OpenNI (for Kinect)
CV_CAP_OPENNI_ASUS =910, // OpenNI (for Asus Xtion)
