    Principle of Optical Flow Ranging Integrated Module

    Optical Flow uses a downward facing camera and a downward facing distance sensor for velocity estimation. It can be used to determine speed when navigating without GNSS — in buildings, underground, or in any other GNSS-denied environment. The video below shows PX4 holding position using the Ark. The micolink is a lightweight protocol customized by MicoAir Tech, prepared for developers who are ready to write their own code to read sensor data. MicoAssitant software can used for configure protocol or other parameter of MTF-01. Step1 : Connect the MTF-01 to PC by using the USB to TTL module. It is well known for frame-based cameras, but given this new event-based paradigm, we adopt new approaches to achieve this goal, while preserving the asynchronous. Optical flow is the pattern of apparent motion of image objects between two consecutive frames caused by the movement of object or camera. Consider the image below (Image.
