Multi-spectrum illumination-and-sensor module for head tracking, gesture recognition and spatial mapping

摘要

A device and method use multiple light emitters with a single, multi-spectrum imaging sensor to perform multi-modal infrared light based depth sensing and visible light based Simultaneous Localization and Mapping (SLAM). The multi-modal infrared based depth sensing may include, for example, any combination of infrared-based spatial mapping, infrared based hand tracking and/or infrared based semantic labeling. The visible light based SLAM may include head tracking, for example.
