Diese Arbeit beschreibt die Aufstellung einer Trajektorie für ein autonomes Fahrzeug. Als Basis dient eine Vorarbeit, bei der ein neuronales Netz das Bild einer Frontkamera eines Autos in Fahrspur und Nicht-Fahrspur segmentiert. Darauf aufbauend wird das Bild zunächst in die Vogelperspektive transformiert. Anschließend folgen eine Detektion der Fahrspurkanten sowie ein Clustering-Verfahren, um linke und rechte Kantenabschnitte zu separieren. Weiter wird die Trajektorie diskret in Form von Parametern des Kreisbogenmodells aufgenommen. Die Prädiktion dieser Parameter erfolgt mittels eines Extended Kalman-Filters. Die abschließende Validierung der Algorithmen erfolgt durch eine synthetisch generierte Fahrspur.
A matter of reality

Due to the increasing relevance of data, more and more data from various sources is accumulated for a variety of purposes. At the same time, however, there is a shortage of data in areas where it is urgently needed. Particularly in the field of machine learning, there is a lack of good and usable training data. Therefore, this research paper is concerned with the virtual data acquisition for the training of neural networks. For this purpose, first an application was developed that aims to generate virtual, automatically labeled data. Subsequently, a neural network was trained on the generated virtual data and tested on real data.
