Sensor Data Time Alignment

摘要

Techniques for sensor data time alignment are described. According to one or more embodiments, sensor data from different sensor systems is time-aligned to a reference time base. For instance, reference time values may be propagated to sensor systems to enable the sensor systems to mark sensor data based on the reference time values. Sensor data from a sensor system may be time-aligned by applying an alignment policy to the sensor data. An alignment policy, for example, accounts for a difference between a time base of a sensor system and a reference time base. Thus, sensor data from different sensor systems may be aligned to common time values in a variety of different ways.

1. A system comprising:
at least one processor; and one or more computer-readable storage media including instructions stored thereon that, responsive to execution by the at least one processor, cause the system perform operations including:
receiving an instance of sensor data that includes a timestamp from a sensor system;ascertaining an alignment policy for the sensor system;applying the alignment policy to a time value of the timestamp to generate an aligned timestamp; andmarking the instance of sensor data with the aligned timestamp to generate a time-aligned version of the instance of sensor data.
