Synset Signset Germany: 105,500 Synthetic Images of 211 Traffic Signs

FraunhoferIOSB developed this collection of 105,500 synthetic images covering 211 German traffic sign classes. It includes rare signs from the 2020 German traffic regulations and provides a synthetic counterpart to the GTSRB benchmark.

Use Cases

• Training image classification models to recognize 211 German traffic sign classes
• Benchmarking synthetic-to-real transfer learning using the 43-class GTSRB synthetic twin
• Testing detection robustness on rare 2020 traffic sign categories

Strengths

• 105,500 total images
• 211 distinct traffic sign classes
• Includes rare 2020 German traffic sign updates

Limitations

• Synthetic data origin may require domain adaptation for real-world deployment
• Potential class imbalance for rare 2020 sign categories
