STRUCTURED LIGHT CODE OVERLAY

Abstract:

Techniques and systems are provided for generating one or more depth maps. For example, a process can include transmitting a pattern of light using a structured light source, the pattern of light including at least a first sub-pattern group of a primitive pattern and a second sub-pattern group of the primitive pattern. The process can include generating an overlapped pattern of light, the overlapped pattern of light including at least the first sub-pattern group of the primitive pattern overlapped with the second sub-pattern group of the primitive pattern. The process can include receiving one or more return signals based on the overlapped pattern of light. The process can include generating a depth map based on the one or more return signals.
