WILSONVILLE, Ore. — According to the 2020 State Farm annual study, nearly two million collisions between vehicles and large animals occur every year in the United States alone, representing approximately five percent of all reported motor vehicle collisions. These wildlife vehicle collisions (WVCs) result in 26,000 injuries to motorists each year.

Thermal cameras see an entirely different wavelength of energy, known as long-wave infrared (LWIR) radiation or heat energy, which radiates, absorbs, or is reflected by everything on earth. With the ability to see heat without visible light, they offer a unique capability to significantly reduce the number of WVCs.

Seeing Beyond Headlights

Thermal cameras are currently offered as an option on several vehicle models as a driver-warning system, but recent developments and testing have shown the potential for thermal cameras to be a valuable part of the automotive sensor suite for functions such as automatic emergency braking (AEB).

Thermal cameras from Teledyne FLIR can see significantly farther than headlights and detect large animals in challenging driving conditions including through darkness, headlight or sun glare, and most types of fog.

Particularly adept at detecting body heat and distinguishing wildlife far down a dark road, thermal imaging can help reduce WVCs, which mainly occur at dusk, night, and dawn when animals are most active, and visibility is limited.

Convolutional neural networks (CNNs) are used to analyze images for certain characteristics and can be trained to detect and classify wildlife. Thermal cameras can be combined with a CNN just like visible cameras, creating a robust method for artificial intelligence to identify and mitigate animal collisions that often occur in challenging lighting conditions.

To support further development, Teledyne FLIR expanded their CNN to detect large animals in addition to its current capacity to detect pedestrians, vehicles, bikes, cars, and multiple other classes of road objects.
