Live Demonstration: a Trimodal Time-of-Flight Camera Featuring Material Sensing

Abstract

Time-of-Flight (ToF) cameras are active sensors able to capture both the light intensity reflected by each observed point in the scene and the distance between these points and the camera. In this live demonstration we present a ToF camera endowed with a third modality: material. The different surface and subsurface scattering characteristics among materials lead to different time-domain responses that are used to effectively distinguish one material from another.
