hi, i have intel realsense camera. i want to interface its depth and infrared with opencv. opencv 2.4.10 have sample of intel camera inteface but its not working properly. can any one guide me in interfacing intel reaslense camera using opencv.

Have you tried the cv::VideoCapture cap(0); (if you have just that camera connected) and then in a for cap >> frame ... etc?

it only accesses rgb camera, i am not able to access depth and ir stream using this

You will need to start for sure with the following option.

VideoCapture cap(0 + CV_CAP_INTELPERC)

This will force the capture interface to use the intel interface. Then it is kind of a wasteland out there. Multiple cap interfaces which are poorly documented. I would take a closer look at the sourcecode found here. I notice that there is a get and set method and that there are parameters CV_CAP_INTELPERC_IMAGE and CV_CAP_INTELPERC_DEPTHMAP so it will be possible to retrieve them there I think.

Especially look at this code line! It seems that you can specify which frame you want to retrieve using the interface!

hi, thanks for your response. i find that in your given link the code is written to interface intel perceptual sdk. and now it is upgraded to intel realsense sdk. i run this it says that cannot open capture object. mean it is not capable to capture image from intel realsense camera.

Ow sorry for the mistake. Then you will have to use the intel API for grabbing the camera data and then push it into a Mat element for opencv by accessing the data pointer.

do you know how to do it. i am stucked into it from last 10 days. i am not getting any solution

I have no experience with the intel SDK, but I am guessing there should be a C or C++ API available right? Can you retrieve the image data using their own framework?

the image data i am getting from sdk is pxcimage and when i am converting to mat image the error occurs that memory access violation.

here is the working code of interfacing intel realsense camera SDK + opencv

Auch, you are including C++ headers but C - API function. I would avoid that. The latest 3.0 branch doesn't even support that anymore. You should get rid of all cvBlaBla functions and replace them by their C++ variant.
