OpenCV + GPU functionality with L515

Follow
Anadig

I am using OpenCV to render frames from the depth camera of the L515. I would like to use the GPU capabilities of OpenCV. Is it possible to do this with the pre-built OpenCV that is provided by Intel? It seems like this OpenCV hasn't been built with GPU capabilities. If this is the case, can you provide steps to add an OpenCV built with GPU capabilities to the existing projects?

    Hello Anadig,

    The Intel RealSense SDK does not come with a pre-built OpenCV distribution. OpenCV must be installed separately. OpenCV has the capability to take advantage of GPUs using CUDA or OpenCL.

    Here is some information for using RealSense cameras with NVidia Jetson devices using CUDA.

    For more specific questions on using OpenCV, you can post questions on the following relevant forums:

    Hello Anadig,

    I misunderstood your question. You are using the binary installation of the RealSense SDK which does come with OpenCV. If you build the RealSense SDK from source you can use whichever version of OpenCV you'd like.

    Follow these instructions to build the RealSense SDK with your own OpenCV distribution.
