Run Asus Xtion with HighGUI - HOWTO?!
Hi,
I am trying to make the Asus Xtion pro live work with my computer. I am using ubuntu 12.04 with Opencv 2.4.6.1. I have been trying this for quite some time now but I cannot make it work.
I downloaded the the tools from http://www.asus.com/Multimedia/Xtion_PRO_LIVE/#support_Download_5 a. PrimeSense Software Package 20.4.2.20 ： 1. OpenNI Framework (Version 1.5.2.23) 2. Sensor DDK (version 5.1.0.41) 3. NITE (version 1.5.2.21) 4. USB driver (version 3.1.3.1)
Then I followed the installation instructions and tried to run the Xtion in NiViewer, which works fine. After that I wanted to make the example code on http://docs.opencv.org/doc/user_guide/ug_highgui.html run.
But when I try to run the code, I get the the error Message "Can not open a capture object", which is cause by
if( isVideoReading )
capture.open( filename );
else
capture.open(CV_CAP_OPENNI );
cout << "done." << endl;
if( !capture.isOpened() )
{
cout << "Can not open a capture object." << endl;
return -1;
}
This is what is mentioned in 2. on http://docs.opencv.org/doc/user_guide/ug_highgui.html. How can I change the CMake variables in Codeblocks? I have no CMakeLists.txt as I just created an empty project and added a .cpp file.
Thanks!
first, make a quick test, to see if openni support was built into your cv libs:
cout << cv::getBuildInformation() << endl;
if not so, you have to rebuild opencv using cmake. like in 2.
" I have no CMakeLists.txt as I just created an empty project and added a .cpp file."
yea, all that is about rebuilding opencv, not your test-program
Thanks for the quick reply! BuildInformation() gave me the following: with getBuildInformation()
Video I/O: OpenNI: NO OpenNI PrimeSensor Modules: NO
sorry for the stupid question, but does that mean it is not supported or just no activated? And when I reinstall opencv, do I have to uninstall the current version first or can I just rebuild it using cmake?
"does that mean is is not supported or just no activated?" - not activated, you'll have to rebuild.
"do I have to uninstall the current version first ?" if you did not build it yourself, - probably.
thank you very much! It works now :).
hey, cool ;)
