Abstract
Methods, apparatus, systems, and computer-readable media for assigning a real-time clock domain timestamp to sensor frames from a sensor component that operates in a non-real-time time-domain. In some implementations, a real-time component receives capture instances that each indicate capturing of a corresponding sensor data frame by the sensor component. In response to a capture output instance, the real-time component or an additional real-time component assigns a real-time timestamp to the capture output instance, where the real-time timestamp is based on the real-time clock domain. Separately, a non-real-time component receives the corresponding sensor data frames captured by the sensor component, along with corresponding metadata. For each sensor data frame, it is determined whether there is a real-time timestamp that corresponds to the data frame and, if so, the real-time timestamp is assigned to the sensor data frame.
