Title: Timestamping and latency analysis for multi-sensor perception systems
Abstract: This paper describes methods and tools for the analysis of measurement timestamps and time delays of different environmental perception sensors for Advanced Driver Assistance Systems (ADAS) in order to allow a proper sensor data interpretation. These sensors are classified according to the way they timestamp their measurements. Thereby, three classes are defined: sensors with global timestamps, sensors with relative timestamps and sensors without measurement timestamps. This paper describes the concept and tools for analyzing and setting the timestamp of sensors from class I and II. For the classI, a global UTC <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> -master time generator allows the creation of a relationship between the measurement and the acquisition timestamps. For the class II, a synchronization signal is periodically sent to the sensors which timestamp their data relative to this reference signal. The used tools for this analysis were thoroughly analyzed and verified.
