WebFeb 1, 2024 · This work proposes a novel direct visual-inertial odometry method for stereo cameras that outperforms not only vision-only or loosely coupled approaches, but also can achieve more accurate results than state-of-the-art keypoint-based methods on different datasets, including rapid motion and significant illumination changes. 201 PDF Webthe first published event-based stereo visual-inertial odome-try (ESVIO). Our contributions are summarized as follows: 1)In order to achieve robust state estimation under ag-gressive motion and low-light scenarios, we propose the first purely event-based stereo VIO (ESIO) pipeline with sliding windows graph-based optimization, and

WebMar 25, 2024 · Event-based cameras are bioinspired vision sensors whose pixels work independently from each other and respond asynchronously to brightness changes, with microsecond resolution. Their advantages... WebThe main contributions can be summarized as follows: 1) We demonstrate that the monoc- ular VO problem can be enhanced with the use of event- 1 streams. 2) We show a fusion based strategy that can help learn good geometrical representations, an inherent need for the VO pipeline using CNNs. full year翻译

WebSep 29, 2014 · Low-latency event-based visual odometry. The agility of a robotic system is ultimately limited by the speed of its processing pipeline. The use of a Dynamic Vision Sensors (DVS), a sensor producing asynchronous events as luminance changes are perceived by its pixels, makes it possible to have a sensing pipeline of a theoretical … WebAn event-based image sensor addresses these drawbacks by mimicking a biological retina. Instead of measuring the intensity of every pixel in a fixed time-interval, it reports events of significant pixel intensity changes. Every such event is represented by its position, sign of change, and timestamp, accurate to the microsecond. WebNov 30, 2013 · Abstract. This paper introduces a new methodology to compute dense visual flow using the precise timings of spikes from an asynchronous event-based retina.
