Optical flow lens
The optical flow system is composed of optical flow lens modules. It is an image positioning system
that locating the drone by optical flow images. It ensures the accurate positioning and safe flight of
the drone.
Measurement accuracy to the Optical Flow System (OPS) is easily affected by light intensity
and texture of the surface. If the OPS fails the drone will automatically switch to fixed altitude
mode. Below is a list of conditions that can cause failure to the OPS:
1. Flying fast at low altitude (below 0.5 meters).
2. Flying over monochrome surfaces such as pure black, pure white, pure red etc.
3. Flying over surfaces with strong reflections.
4. Flying over water or transparent surfaces.
