US 11,700,061 B1 · Apparatus for synchronizing operation of optical sensors and a method for using same

Abstract

A central unit is provided which is operative in a system that comprises a plurality of moveable devices, each comprising an optical depth sensor. The central unit comprises a processor adapted to: divide the moveable devices into a plurality of groups, wherein each of the groups is characterized by a specific wavelength range at which all projecting modules associated with the optical depth sensors of the moveable devices belonging to that group, are operative; establish a time frame within which each of the optical depth sensors of the moveable devices will operate, wherein the time frame comprises a plurality of time slots; and associate at least two of the moveable devices with a single time slot, wherein each of the at least two moveable devices belongs to a different group than the other.
