  • Patent number: 10771669
    Abstract: Sensor data produced in a multi-sensor environment is time synchronized, such as using a master time. A component that derives the master time transmits a signal to a first sensor of the multi-sensor environment, which signal indicates the master time. The component subsequently receives a signal from the first sensor, which signal indicates a first time determined by the first sensor based on the master time and a latency associated with the first sensor. The first time indicates a time of an event associated with the first sensor data. A determination is then made that the first sensor data corresponds to second sensor data produced using a second sensor of the multi-sensor environment based on the first time and a second time indicating a time of an event associated with the second sensor data.
