OAK-FFC-pToF
Overview :The OAK-FFC-pToF is a carrier board for the Sunny MTP006 pTOF camera module, and is designed to be compatible with OAK-FFC-3P, OAK-FFC-4P, and DepthAI RPi HAT baseboards. It’s currenty in beta stage so you have to use a custom version of the depthai library to communicate with this FFC module.
Getting started :To get started with OAK-FFC-pToF, you first need to install the correct version: checkout to branch tof_rgb_mono in depthai-python and execute python3 examples/install_requirements.py. After installing the library, you can run the cam_test.py demo by executing python3 tests/cam_test.py.It shows colorized depth by default, and you can add -tofcm argument for the pixels to show a value in centimeters (capped to 255). This allows you to easily check depth from an OpenCV window, as it’s displayed in the bottom-left corner when hovering with the mouse.The out output of the ToF node sends ImgFrame message of 224x172 size, and the data type is U16 - depth in millimeters.
