TBBR Raw Images: Hyperspectral Drone Imagery of Karlsruhe Building Rooftops

March 19, 2019 from 7 a.m. to 8 a.m. is the temporal coverage for this collection of 5,696 raw drone images (2,848 RGB and 2,848 thermal) of building rooftops in Karlsruhe, Germany. The data was recorded by J. Kahn of the Karlsruhe Institute of Technology using a DJI M600 drone equipped with RGB and FLIR-XT2 thermal cameras. Images show six large building blocks with high overlap, capturing each building from multiple angles.

Use Cases

• Training thermal bridge detection models based on paired RGB and thermal imagery.
• Developing image registration or fusion algorithms for hyperspectral drone data.
• Analyzing urban heat patterns on building rooftops based on thermal data captured under specific environmental conditions.
• Creating 3D reconstructions or building models based on the high-overlap RGB images.

Strengths

• Contains 5,696 precisely paired images (2,848 RGB and 2,848 thermal), providing a substantial multimodal corpus.
• Images were captured under controlled, documented environmental conditions (temperature, humidity, radiation).
• High image overlap provides approximately 20 different angles per building, useful for 3D analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Data is limited to a single one-hour flight on a specific day, which may not represent seasonal or weather variations.
