+
+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 Luxonis DepthAI library [depthai-core](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.
