Optical Flow Positioning
The Optical Flow Positioning System
consists of a camera module, which
acquires the position information of the
drone through visual images to ensure
precise positioning of the drone.
The Optical Flow Positioning System is
typically used in an indoor environment
when the GPS signal is weak or unavail-
able. The optimal usage height for Opti-
cal Flow Mode is 1.6-9.8 ft.
- The precision of the Optical Flow Positioning System is easily affected by the light
intensity and features of the surface textures. Once the image sensor is not available,
your drone will switch on the altitude-hold function automatically. Please exercise
utmost caution when operating the drone under these circumstances:
