HiFi Visual Target—Methods for Measuring Optical and Geometrical Characteristics of Soft Car Targets for ADAS and AD

Advanced Driver-Assistance Systems (ADAS) and Automated Driving (AD) vehicles rely on a variety of sensors and among them optical sensors. Extensive testing of functions using optical sensors is required and typically performed at proving grounds like AstaZero. Soft surrogate targets are used for safety reasons but the optical and geometrical characteristics of soft car targets may differ considerably from that of real vehicles. During tests the quality of the soft car targets deteriorates due to repeated impacts and reassembly of the targets, and there is a need of methods for securing the quality of the soft car targets over time. One of the main goals of the HiFi Visual Target project is to develop and validate accurate and repeatable measurement methods of the optical and geometric characteristics of soft car targets.
