Patent attributes
A system includes a depth sensing device that includes a depth sensor. The depth sensor includes an infrared projector and an infrared camera. The system includes a processor coupled to the depth sensor and a memory accessible to the processor, and programming in the memory. Execution of the programming by the processor configures the system to perform functions, including functions to project, via the infrared projector, a pattern of infrared light on a plurality of objects located in a space that are reached by the projected infrared light. The plurality of objects includes objects of interest and light fixtures in the space. The execution of the programming by the processor further configures the system to determine light fixture location coordinates for each of the light fixtures based on computed distances between the objects of interest and each of the light fixtures based on distortions of the projected infrared light.
