Abstract
A method implemented by a first time of flight (ToF) sensor includes generating, by the first ToF sensor, a first depth map in accordance with measurements of reflections of an optical signal emitted by the first ToF sensor; communicating, by the first sensor with a second ToF sensor, the first depth map and a second depth map, the second depth map generated by the second ToF sensor; and determining, by the first ToF sensor, a relative location of the first ToF sensor relative to the second ToF sensor in accordance with the first depth map and the second depth map.

A method implemented by a first time of flight (ToF) sensor, the method comprising:
- generating, by the first ToF sensor, a first depth map in accordance with measurements of reflections of an optical signal emitted by the first ToF sensor;
- communicating, by the first ToF sensor with a second ToF sensor, the first depth map and a second depth map, the second depth map generated by the second ToF sensor;
- and
- determining, by the first ToF sensor, a relative location of the first ToF sensor relative to the second ToF sensor in accordance with the first depth map and the second depth map.
A method implemented by a first device having a first time of flight (ToF) sensor, the method comprising:
- obtaining, by the first device from the first ToF sensor, a first depth map generated from measurements of reflections of an optical signal emitted by the first ToF sensor;
- communicating, by the first device with a second device having a second ToF sensor, the first depth map and a second depth map, the second depth map generated by the second device;
- determining, by the first device, a relative location of the first device to the second device in accordance with the first depth map and the second depth map;
- and
- adjusting, by the first device, a location of the first device in accordance with the relative location of the first device.
A first device, comprising:
- a time of flight (ToF) sensor configured to emit an optical signal and measure reflections of the optical signal;
- one or more processors;
- and
- a non-transitory memory storage comprising instructions that, when executed by the one or more processors, cause the first device to:
- obtain, from the ToF sensor, a first depth map generated from the measurements of the reflections of the optical signal emitted by the ToF sensor;
- communicate, with a second device having a ToF sensor, the first depth map and a second depth map, the second depth map generated by the second device;
- determine a relative location of the first device to the second device in accordance with the first depth map and the second depth map;
- and
- adjust a location of the first device in accordance with the relative location of the first device.
