A recently granted patent (Publication Number: US11915512B2) discloses a three-dimensional sensing system that utilizes a plurality of scanners to capture depth information of a scene. Each scanner in the system consists of a transmitter, a receiver, and a controller. The scanners operate in a coordinated manner, with only one scanner transmitting and receiving light signals at a time. The system can employ structured light or time-of-flight techniques to capture depth information by projecting patterns onto the scene or measuring the round trip time of reflected light signals.

Furthermore, the patent describes the activation of the scanners through trigger signals, with configurations involving a master-slave relationship or a host-guest setup. Trigger signals are generated and received by controllers or receivers of the scanners, ensuring synchronized operation. The system also includes a host component that issues trigger signals to activate the scanners sequentially. This innovative three-dimensional sensing system offers a sophisticated approach to capturing depth information efficiently and accurately, with potential applications in various fields requiring precise spatial data collection.
