It is one of the easiest and most established ways to calculate the optical flow. ARK Flow ARK Flow is a DroneCAN optical flow sensor, distance sensor, and IMU.
WebTo calculate optical flow, we used the Lucas-Kanade Method. The Lucas-Kanade Method uses the assumption that all neighboring pixels will have similar motion to extract optical flow. Their method assigns a weight function to the pixels and then uses the Weighted Least Squares method to formulate an equation to derive motion [2]. Extracting Motion WebOptical Flow Sensor Testing and Setup Testing the sensor With the sensor connected to the autopilot, connect to the autopilot with the Mission Planner and open the Flight Data screen's Status tab. If the sensor is operating you should see non-zero opt_m_x, opt_m_y and opt_qua values. Calibrating the sensor
