Stereo Event Lifetime and Disparity Estimation for Dynamic Vision Sensors [PDF]

2019 European Conference on Mobile Robots (ECMR), 2019
Event-based cameras are biologically inspired sensors that output asynchronous pixel-wise brightness changes in the scene called events. They have a high dynamic range and temporal resolution of a microsecond, opposed to standard cameras that output frames at fixed frame rates and suffer from motion blur.
