Embodiments are generally directed to identification of objects for three-dimensional depth imaging. An embodiment of an apparatus includes one or more processors to process image data and control operation of the apparatus; an image sensor to collect image data; and a receiver and transmitter for communication of data, wherein the apparatus is to receive a notification of a first device entering a physical space, transmit a request to the device for a light signal to identify the device, detect the light signal from the device, determine a location of the device, and store an identification for the first device and the determined location of the first device in a database.
