Abstract
This paper deal with the problem of executing a vision-based task in an unknown environment. During such a task, two unexpected events may occur: the image data loss due to a camera occlusion and the robot collision with obstacles. We first propose a method allowing to compute the visual data when they are totally lost, before addressing the obstacle avoidance problem. Then, we design a sensor-based control strategy to perform safely vision-based tasks despite complete loss of the image. Simulation and experimental results validate our work.

Abstract
In this article, we address the problem of computing the image features when they become temporarily unavailable during a vision-based navigation task. The method consists in analytically integrating the relation between the visual features motion in the image and the camera motion. Then, we use this approach to design sensor-based control laws that are able to tolerate the complete loss of the visual data during a vision-based navigation task in an unknown environment. Simulation and experimentation results demonstrate the validity and the interest of our method.
