Abstract
A sensor calibration target includes dark markings on a light substrate. The dark markings absorb more heat from a heat source than the light substrate, and are visually distinguishable from the light substrate. Thus, the dark markings are discernable by the both a camera and an infrared sensor of a vehicle during vehicle sensor calibration. The sensor calibration target may otherwise non-metallic but include a metallic feature for calibrating a radio detection and ranging (RADAR) sensor. The sensor calibration target may also include one or more apertures in the substrate for calibrating a light detection and ranging (LIDAR) sensor.
