A matter of reality
(2018)
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.

Diese Arbeit beschreibt ein Referenzsystem,
welches die Trajektorie eines Modellfahrzeugs mithilfe einer
Deckenkamera ermittelt.
Hierbei wird die Position eines Fahrzeugs durch die Kombination
von mehreren Bildverarbeitungsverfahren bestimmt.
Anschließend erfolgt die Verbesserung der Messdaten sowie die
Schätzung von nicht direkt messbaren Größen mithilfe eines
Partikelfilters. Die abschließende Zuordnung der Referenzinformationen
zu den On-Board-Messwerten wird durch eine
Zeitsynchronisation zwischen Fahrzeug und Referenzsystem
ermöglicht.
Das entwickelte System stellt somit eine hochgenaue Vergleichsbasis
für die Validation und die Abschätzung der
Genauigkeit von Lokalisationsverfahren bereit und erleichtert
daher die Entwicklung autonomer Fahralgorithmen.
