Optical Flow Vision System - SJRC F22S Instructions Manual

9. OPTICAL FLOW VISION SYSTEM

The aircraft is equipped with a downward looking optical flow system, which
is composed of downward looking visual camera sensors, so that the UAV
can hover stably at low altitude without GPS or with weak GPS signals.
Note:
(1) The optical flow vision system can only assist in flight when the
surrounding environment is full of light and rich in texture but cannot
completely replace the user's judgment. Please pay attention to the
aircraft situation and APP tips and please DO NOT rely too much on the
optical flow vision system.
(2) The optical flow vision system is ineffective or ineffective in situations
where the ambient light is too bright or too dark, mirror surface, pure
color smooth ground, water surface, reflective surface, texture sparse
surface, etc.
(3) The best working range of the down view optical flow vision system is
below 0.5-3 meters. If it exceeds this range, the positioning effect of the
down view optical flow vision system may be poor. Please fly with caution.
(4) Please ensure that the lens of the optical flow vision system is clear and
DO NOT block or interfere the optical flow vision system.
(5) The optical flow vision system can only be used in the Alititude Mode
and change to the GPS mode automatically outdoors after GPS satellite
search successfully.
