Abstract :
Triggered vision systems show several difficulties mainly concerning adaptation to varying lighting conditions. This paper presents a novel technique that makes possible that asynchronous triggered vision systems perform in outdoor environments. We propose to use an adaptive PID controller to adjust the exposition time of a LinLog sensor, together with an adaptive background estimation algorithm followed by an image restoration.
