Abstract:
The present disclosure relates to systems and methods that provide information about a scene based on a time-of-flight (ToF) sensor and a structured light pattern. In an example embodiment, a sensor system could include at least one ToF sensor configured to receive light from a scene. The sensor system could also include at least one light source configured to emit a structured light pattern and a controller that carries out operations. The operations include causing the at least one light source to illuminate at least a portion of the scene with the structured light pattern and causing the at least one ToF sensor to provide information indicative of a depth map of the scene based on the structured light pattern.
