Development of a synchronisation subsystem for a LIDAR system
| Resumo: | Advanced driver assistance systems (ADAS) promise to reduce the number of deaths, relieve driver stress, minimise pollution and traffic problems and develop improved public transport. New technological advances, such as the implementation of multiple cameras, LiDARs, radars and ultrasonic sensors, in addition to conventional sensors in cars, have enabled the development of ADAS systemsusing fusion of data from multiple sensors, known as sensor fusion. In order to carry out data fusion, it was necessary to start exploring network protocols to connect all the car’s systems. Furthermore, as a requirement for time-sensitive automotive applications, particularly safety-critical ones, it is necessary for all systems to have a precise and common time scale. In this context, the main objective of this dissertation was to design and develop a system capable of synchronising an automotive system with multiple Sensor Heads, each composed of a LiDAR sensor, this system being called System-in-Package LiDAR. This dissertation presents the development and implementation of a clock synchronisation module capable of satisfying the requirements of System-in-Package LiDAR systems, as well as the methods for adapting it to the chosen evaluation boards. Finally, the effectiveness of the System-in-Package LiDAR synchronisation system was tested under different network and load topologies. |
