Design and Implementation of Edge-Fog-Cloud System through HD Map Generation from LiDAR Data of Autonomous Vehicles

Abstract: Self-driving cars, autonomous vehicles (AVs), and connected cars combine the Internet of Things (IoT) and automobile technologies, thus contributing to the development of society. However, processing the big data generated by AVs is a challenge due to overloading issues. Additionally, near real-time/real-time IoT services play a significant role in vehicle safety. Therefore, the architecture of an IoT system that collects and processes data, and provides services for vehicle driving, is an important considerat… Show more

“…Their neural network predicted the map elements observed in a bird's-eye view into a vectorized map. Meanwhile, Junwon et al [27] introduced the Edge-Fog-Cloud architecture to generate HD maps from vehicle sensor data. The Fog server performed the normal distribution transform-simultaneous localization and mapping (NDT-SLAM) to generate an HD map from the LiDAR point cloud, while the cloud server converted the generated HD map to a global coordinate frame for compilation.…”

“…However, the database does not directly store and process point cloud data about buildings but only stores two-dimensional (2D) information in a top-view format, making it challenging to apply to the dynamic autonomous driving environments considered in the present study. Lee et al proposed a fog computing server model that applied the normal distributions transform-simultaneous localization and mapping (NDT-SLAM) technique to LiDAR data generated from vehicles to create an HD (high-definition) map [12]. This study was significant, as it used Hadoop to store large amounts of point cloud data and created precision maps using SLAM techniques.…”

“…Connected Vehicles: In future autonomous vehicles, an object detection task can be performed collaboratively using distributed computing or joint training and inference [18], [20]. Methods proposed in this category include deploying AI models through edge computing, fog computing, cloud computing or their respective combinations [3], [22], [31], [33], [36]. As the AI model, such as DNN, can be dense in size and may require high computational resources, it is practically challenging to deploy them on Edge devices.…”
