Advanced Driver Assistance Systems (ADAS) rely on camera sensors to work effectively to provide warning signs to prevent forward and rearward collision, lane departure, pedestrian detection, traffic sign recognition, automatic headlight control and assists for autonomous driving. Generally, vision based ADAS systems have wide angle cameras installed on front, rear and sides of the vehicle. These camera-based vision sensors are subjected to severe thermal environments that can impact its sensing performance and image quality. Hence it is imperative to thermally qualify the camera module to ensure reliable performance without loss in functionality. The thermal environment experienced by these cameras vary based on their mounting location. Intelligent forward view cameras are mounted in windshield region of the vehicle and encounter sun load in order of 1000 W/m2.
