Abstract
Nowadays, more than in the past, research is focused on the study and development of enabling technologies to achieve the goal of autonomous navigation. The investigations cover all industrial fields: automotive, aerospace, and maritime. The first level to be developed to achieve the goal of autonomous vehicles is obstacle detection and consecutively object tracking in real-time. The most important results were obtained in the automotive sector, where the available financial resources are more significant than the others. Indeed, several methods based on trained neural networks are used to detect the obstacles. Usually, the neural networks are trained by using large datasets of LiDAR point clouds and images. Unfortunately, it is impossible to emulate this approach in the marine sector because there are no large datasets for training a neural network. For such a reason, this paper aims to present multi-object tracking based on unsupervised learning. The proposed method is tailored for the challenging marine environment, and it is suitable for the detection and tracking of both fixed and moving obstacles. This paper presents a low-computational method for multi-object tracking based on unsupervised learning, and it is discussed and analysed step by step, indicating the pros and weaknesses. Moreover, the tracking has been tested on both experimental LiDAR point clouds and virtual LiDAR point clouds created employing a tailored virtual scenario. The results are reported and discussed.File | Dimensione | Formato | |
