Abstract
Systems and methods to improve safety and more efficient Advanced Driver Assistance Systems (ADAS) and autonomous vehicle (AV) systems for vehicular operation through the application of multiple thermal sensors arranged in systems where the resolution, Field Of View (FOV), and aiming angle of individual sensors are varied. In particular two configurations are discussed in detail, a three-sensor arrangement for forward and forward off angle data acquisition, and a two or three sensor arrangement for blind spot and pinch point awareness for towing applications. In some forward-looking three-sensor embodiments, the center sensor may provide a high-quality narrow field of view of radiometric data for use with tracking algorithms to identify pedestrian and large animal targets for long range driver identification. The side sensors may provide radiometric data for peripheral vision on short/medium range approaching targets for situational awareness at crosswalks and turning corners.
