Depth sensors compatible with Luxonis DepthAI library are supported through OpenCV Graph API (or G-API) module. RGB image and some other formats of output can be retrieved by using familiar interface of G-API module.

In order to use DepthAI sensor with OpenCV you should do the following preliminary steps:
-#  Install Intel DepthAI library/depthai-core (from here <https://github.com/luxonis/depthai-core>).

-#  Configure OpenCV with DepthAI library support by setting WITH_OAK flag in CMake. If DepthAI library is found in install folders OpenCV will be built with depthai-core  (see a status WITH_OAK in CMake log).

-#  Build OpenCV.

Source code
-----------

You can find source code how to process heterogeneous graphs in the `modules/gapi/samples/oak_basic_infer.cpp` of the OpenCV source code library.
