Reduced spatiotemporal bandwidth of motion stabilized event-based imaging sensors: experimental demonstration

Abstract

This work investigates event-based sensor (EBS) imaging system’s read-out bandwidth performance under linear motion, with and without hardware stabilization techniques. We implement three image stabilization methods using hardware rotation to cancel the sensor platform’s linear motion and recapture lost EBS performance. We successfully demonstrated the methods, showing a bandwidth reduction of over an order of magnitude in two scenes, 10 scene variations, and five EBS velocities. This work demonstrates the benefits of stabilization with EBS to reduce bandwidth requirements versus unstabilized EBS systems.
