Teledyne FLIR today announced the release of an expanded free thermal dataset for Advanced Driver
Assistance Systems (ADAS) and self-driving vehicle researchers and developers. The expanded starter
dataset nearly doubles the original, industry-first free dataset and features more than 26,000 annotated
images from the US, England, and France in day and nighttime conditions. It also triples the number of
categories and now includes person, bike, car, motorcycle, bus, train, truck, traffic light, fire hydrant, street
sign, dog, skateboard, stroller scooter, and other vehicle labels. The expanded free starter thermal imaging
dataset allows the automotive and academic community to quickly evaluate the vehicle safety algorithm
performance, neural network testing, and thermal sensors, such as the FLIR ADK™.
“The industry-first free thermal dataset has been used by developers and as a tool in academic research to
explore safety of automated driving technology with thermal imaging,” said Chris Posch, director of
automotive engineering at Teledyne FLIR. “The expanded dataset, with more images and categories, will
further enhance detection and classifications models, especially focused on automatic braking capabilities as
part of a multispectral, sensor-fused system.
”When combined with visible light cameras, LIDAR, and radar, thermal sensors help create a comprehensive
and redundant system to identify and classify roadway objects using sensor fusion data. Testing has
demonstrated that thermal sensors are uniquely capable of seeing pedestrians, large animals, and other
vulnerable road users in conditions where current automatic emergency braking (AEB) systems are
challenged, including win total darkness, most fog, smoke, shadows, inclement weather, and sun or
In an ongoing effort to make roads safer, twenty automakers committed to the U.S. Congress that all newly
manufactured cars and trucks will be equipped with AEB systems by September 1,2022. Furthermore, highprofile
testing and demonstrations from leading organizations including AAA, demonstrate the need for more
effective and intelligent systems to improve vehicle safety, especially in challenging conditions where thermal
cameras excel. With the potential for millions of thermal-enabled AEB on vehicles, Teledyne FLIR anticipates
the cost of its thermal sensor to continue to decrease significantly, which will encourage wide-scale adoption
and ultimately enable safer vehicles and roads.
