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:

  1. Install Luxonis DepthAI library depthai-core.
  2. 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).
  3. 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.
