CMOS-SPAD Camera Prototype for Single-Sensor 2D/3D Imaging

Abstract

One of the research lines explored in project ‘iCaveats’ has been the combined capture of 2D and 3D visual information. With the objective of power-efficient feature learning/extraction, combined 2D/3D imaging is a useful tool to work on a lightweight but rich description of the scene. Single-sensor capture of both modalities is a potential improvement in cost and efficiency. In this demo, we present the performance and features of a CMOS-SPAD camera prototype that realizes photon counting and direct time-offlight (d-ToF). The central elements of the camera module are a 64×64 SPAD imager and a FPGA board for real time histograming and image reconstruction at 1kfps
