FLIR European Regional Thermal Dataset for Algorithm Training

The FLIR Enhanced European Thermal Dataset is available for sale to automotive developers. It enables developers to start training convolutional neural networks (CNN), empowering the automotive community to create the next generation of safer and more efficient ADAS and driverless vehicle systems using cost-effective thermal cameras from FLIR.

The dataset was acquired via a thermal camera mounted on a vehicle. It contains a total of 14,353 annotated thermal images with 3,554 images sampled from short videos and 10,799 images from a continuous 360-second video. Videos were taken at a variety of locations, light conditions, and weather conditions (see "extra_info" in the images section of the annotations json).

The videos were captured at the following locations London (England); Paris (France);  Madrid, Toledo, Granada, Malaga (Spain)




Why Use FLIR Thermal Sensing for ADAS?

The ability to sense thermal infrared radiation, or heat, within the ADAS context provides both complementary and distinct advantages to existing sensor technologies such as visible cameras, Lidar and radar systems:

  • With over 15 years of experience working with Veoneer to make the only automotive-qualified thermal camera, FLIR’s thermal sensors are deployed in over 600,000 cars today for driver warning systems.
  • The FLIR thermal cameras can be used to detect and classify objects in challenging conditions including total darkness, fog, smoke, inclement weather and glare, providing a supplemental dataset beyond LiDAR, radar and visible cameras. 
  • When combined with visible-light data and distance scanning data from LiDAR and radar, thermal data paired with machine learning creates a more comprehensive detection and classification system.
