What is an optical flow camera?

The PX4FLOW (Optical Flow) Sensor is a specialized high resolution downward pointing camera module and a 3-axis gyro that uses the ground texture and visible features to determine aircraft ground velocity.

What is an optical flow camera on a drone?

“Optic flow is the apparent motion of objects caused by your own motion; as you descend to the ground a downward-pointing camera will see objects on the ground looming larger as it approaches them,” he explained.

What is optic flow used for?

Optical flow was used by robotics researchers in many areas such as: object detection and tracking, image dominant plane extraction, movement detection, robot navigation and visual odometry. Optical flow information has been recognized as being useful for controlling micro air vehicles.

What is optic flow example?

Essentially, optic flow is the apparent visual motion that you experience as you move through the world. Suppose you sitting in a car or a train, and are looking out the window. You see trees, the ground, buildings, etc., appear to move backwards. This motion is optic flow.
