AI-based recognition of car brands and years of manufacture using synthetic data

Expertise

As part of several research and development projects, including the "FeinSyn" project funded by the state of Baden-Württemberg, an approach has been developed to train AI-based VMMRs on simulated, i.e. synthetic, training data. New or specific vehicle models can thus be added "on demand" with just a few mouse clicks.

With »Synset Boulevard« (https://synset.de/) the first large synthetic data set for VMMR worldwide was created, evaluated and made available as an open data set as part of the "FeinSyn" project. The dataset was used to show that the approach achieves equivalent results to training on real data - but with considerably less effort and significantly greater timeliness.

Added value

The approach developed combines state-of-the-art AI methods for "Vehicle Make and Model Recognition" with tools for the synthetic generation of training data. This enables the reliable and flexible recognition of vehicles with full transparency and control over the data sets. New models can be added even before they are used in traffic, as can any country-specific models.

In particular, the approach enables a very high specificity of recognition, right down to specific facelift versions or equipment variants.

The methods were tested in use with the Videmo 360 software for merging and evaluating data from a wide variety of camera data streams. In conjunction with the Ternica VES camera system, the data can be captured flexibly from the emergency vehicle and the information can be merged via the cloud.
