Altitude & Attitude Estimation For UAVs In Dark Environment

Abstract—This work presents a system dedicated to the realtime

estimation of attitude and altitude for unmanned aerial

vehicles (UAV) under low light and dark environment. This

system consists in a fisheye camera, which allows to cover a

large field of view (FOV), and a laser circle projector mounted

on a fixed baseline. The approach, close to structured light

systems, uses the geometrical information obtained by the projection

of the laser circle onto the ground plane and perceived

by the camera. We present a theoretical study of the system in

which the camera is modelled as a sphere and show that the

estimation of a conic on this sphere allows to obtain the attitude

and the altitude of the robot. We propose some experiments

based on simulated data but also real sequences. The estimated

attitude and altitude from our method are comparable with

commercial sensors according to its accuracy and correctness.

The results also prove its suitability for autonomous take-off

and landing as well as in the case of low altitude manoeuvres in

dark environments. It also provides room for additional payload

to be used for different applications due to use of lighter single

micro-camera and laser system.
