Abstract
An apparatus for localizing a first device includes a time of flight circuit configured to emit a first modulated light signal and receive a reflection of the first modulated light signal from the first device. The apparatus further includes a processing circuit configured to determine, based on the first modulated light signal and the reflection, a position of the first device in a first coordinate system associated with the apparatus. The processing circuit is further configured to determine, based on the position of the first device in the first coordinate system, a position of the apparatus in a second coordinate system and an orientation of the apparatus in the second coordinate system. The apparatus further includes a transmit circuit configured to emit a second modulated signal to the first device, wherein the second modulated signal includes data indicating the position of the first device in the second coordinate system.
