Compressive temporal imaging using a rolling shutter camera array

Compressive temporal imaging using a rolling shutter camera array

Abstract

In this work, we present a novel camera array that exploits the electronic rolling shutter to achieve high speed compressive temporal imaging. Traditional compressive temporal imaging makes use of mechanical coded apertures, despite implementation and calibration challenges. Instead, we propose to model the inherent spatial and temporal coding provided by the distinctive rolling shutter sampling from each camera of the array as a compressive temporal imaging system matrix. Thus, we can recover a high speed video from a set of snapshots from the camera array by using compressive sensing reconstruction algorithms. We present both simulation and experimental results for a 4-camera array system with different orientation angles, reconstructing up to 56 high-speed sub-frames from a set of simultaneously triggered snapshots from the array, achieving a compression rate of up to 14X.
