  • Patent number: 12066539
    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.

  • Publication number: 20240201383
    Abstract: A method includes estimating first distance values associated with a plurality of first pixels, based on light pulses of a first light pulse train having a first period, estimating second distance values associated with a plurality of second pixels, the second distance values being estimated for each second pixel based on a second light pulse train having a second period different from the first period, for each of the first pixels being adjacent to one of the second pixels, validating or invalidating the first distance values, based on a comparison between the estimations of the first distance value and at least one of the second distance values of at least one second adjacent pixel, and storing an indication of the first pixels having been validated and/or invalidated.
