DEPTH MEASUREMENT USING MULTIPLE PULSED STRUCTURED LIGHT PROJECTORS
First Claim
1. A depth measurement assembly (DMA) comprising:
- a pulsed illuminator assembly comprising at least two structured light projectors, wherein each of the structured light projectors are configured to project pulses of structured light at a pulse rate into a local area at different times in accordance with depth instructions;
a depth camera assembly configured to capture image data of a portion of the local area illuminated with the pulses of structured light in accordance with depth instructions and, wherein an exposure interval of the depth camera is pulsed and synchronized to the projected pulses;
a controller configured to;
generate the depth instructions;
provide the depth instructions to the depth camera and the structure light source, anddetermine depth information of an object in the local area based in part on the image data.

Abstract
A depth measurement assembly (DMA) includes a pulsed illuminator assembly, a depth camera assembly, and a controller. The pulsed illuminator assembly has a structured light projector that projects pulses of structured light at a pulse rate into a local area. The depth camera assembly captures images data of an object in the local area illuminated with the pulses of structured light. An exposure interval of the depth camera assembly is pulsed and synchronized to the pulses projected by the pulsed illuminator assembly. The controller controls the pulsed illuminator assembly and the depth camera assembly so that they are synchronized. The controller also determine depth and/or tracking information of the object based on the captured image data. In some embodiments, the pulsed illuminator assembly have a plurality of structured light projectors that projects pulses of structured light at different times.
