Exploiting Event-based Cameras for Enhanced Dynamic Motion Analysis

This work explores the use of novel event-based camera technology to extend camera-based dynamic testing to higher frequencies than achievable with conventional frame-based cameras alone.An asynchronous fusion framework is developed to combine frame-and eventbased measurements, leveraging the high temporal resolution of event cameras and the high spatial resolution of frame cameras to monitor higher frequency component displacements. GOAL• Event cameras capture rapid intensity changes with high temporal resolution, enabling the extraction of temporally dense feature tracks and therefore vision-based measurements of high-frequency motion.
