Real time navigation using event cameras
Event cameras, such as the Dynamic Vision Sensor DVS), are bio-inspired vision sensors that output pixel-level brightness changes instead of standard intensity frames. They offer significant advantages over standard cameras, namely a very high dynamic range, no motion blur, and a latency in the order of microseconds. However, because the output is composed of a sequence of asynchronous events rather than actual intensity images, traditional vision algorithms cannot be applied, so that new algorithms that exploit the high temporal resolution and the asynchronous nature of the sensor are required.
We have recently acquired such a camera and the project will explore this new device and research how they can be used for robotics and especially navigation. As this is a very nascent field, we expect that the student will discover new applications as he/she goes along and this should also become part of the investigation.
