Using “silicon retina” event cameras for quick visual robots

ETH Zürich, Switzerland Abstract

Dynamic vision sensor (DVS) event cameras output a sparse asynchronous stream of brightness change events. They could offer a solution to the latency versus power tradeoff faced by conventional cameras, which must burn more power to get less latency. The local gain control and active feedback in DVS logarithmic photoreceptors allows >100dB DR and kHz closed loop robot bandwidth. This talk will show examples of using DVS for quick visual feedback robots. Recently, we have also been developing DNN accelerators using similar sparsity principles as DVS. I will do a live demonstration of some of these principles
