Abstract

In this paper, we proved that the correspondence cue focusing on the local angular variance of the structured light field could provide constraint conditions to deal with the phase ambiguity. A novel method of light-field depth estimation directly using wrapped phases was proposed, avoiding system calibration and adapting to the measurement environment and requirements.
