Operating environment
Forward, backward, left and right:
Surface with clear patterns and adequate lighting
(> 15 lux, indoor fluorescent lamp, environment with
normal light exposure)
Upward: surface built from special materials that can
reflects light diffusely and diffuse reflection > 20%
(such as walls, trees. and persons)
Downwards: the ground has a rich texture and
sufficient light.
