Precision prediction of time-of-flight sensor measurements

Abstract

Systems and techniques are provided for predicting precision of time-of-flight (TOF) sensor measurements. An example process includes receiving depth data associated with a frame, the depth data being captured by a TOF camera by illuminating a modulated signal of the TOF camera and receiving a reflected signal at the TOF camera, wherein the depth data comprises a plurality of correlation samples based on the reflected signal; receiving, from the TOF camera, grayscale image data corresponding to the frame; determining a modulation amplitude of the modulated signal based on the plurality of correlation samples; determining one or more parameters associated with at least one of the depth data and the grayscale image data; and determining a reliability of the depth data based on the modulation amplitude of the modulated signal, the grayscale image data, and the one or more parameters.
