无法使用Asus Xtion Pro Live从VideoCapture OpenCV抓取图像 [英] Can not grab image from VideoCapture OpenCV with Asus Xtion Pro Live
问题描述
我刚刚安装了 OpenCV 2.4.7 与 OpenNI 和primesense传感器，信息。
I just installed OpenCV 2.4.7 with OpenNI and primesense Sensor as it can be seen in the following build information.
我从 VideoCapture 对象抓取问题。例如，如果我运行openni_capture示例，我得到不能抓图像。但我得到有关深度和RGB摄像机的信息，所以我想我得到 VideoCapture 对象正确打开，但在尝试抓取图像的时候，抓函数返回0。
I have problems grabbing from a VideoCapture object. For instance, if I run the openni_capture example, I get "Can not grab images." but I get info about the depth and RGB cameras, so I think I'm getting the VideoCapture object properly opened, but by the time it tries to grab an image, the grab function returns 0.
我使用的是Asus Xtion Pro Live和OpenNI和Sensor正常工作，因为我可以运行NiViewer等示例。
I am using an Asus Xtion Pro Live and OpenNI and Sensor are working properly since I am able to run examples such as NiViewer.
我非常感谢您对此问题的一些帮助。
I would appreciate some help with this problem.
谢谢！

我实例化视频捕获并尝试抓取图像如下：
I instantiate the videocapture and try to grab an image as follows:
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;
}
推荐答案
是使用kinect openni驱动程序而不是asus openni驱动程序
Based on your code my guess is that will use the kinect openni driver as opposed to the asus openni driver
如何：
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;
}
我过去用opencv设置了两个asus xtion pro传感器，您可以在此处查看代码查看我的测试。
此外，这些是来自 highui types header ，并附加注释：
Also, these are the values from the highui types header, with comments:
CV_CAP_OPENNI =900, // OpenNI (for Kinect)
CV_CAP_OPENNI_ASUS =910, // OpenNI (for Asus Xtion)
