Automotive Imaging for Safer Driving
The Automotive Imaging system provides comprehensive measurements with highest precision for safer automotive driving. Diopter measurements as well as ADAS image analysis are carried out with just the same hard- and software tools.
For diopter measurements the inspected windshield is placed in front of a high-resolution digital camera recording images of a calibration pattern displayed on a wide-screen monitor behind the windshield. The measured displacement field of the pattern through the windshield yields directly the diopter map. The field of view is freely selectable changing the camera position and can cover the whole windscreen or smaller segments like the ADAS viewport. Fully automated diopter measurements are carried out on car glass test benches as well as inspecting already installed windscreens from inside of the car. |

The same imaging system quantifies the image quality of the ADAS camera performance in terms of the Modulation Transfer Function (MTF), image contrast and relative brightness (transmission). Other image quality indicators like secondary-image separation according to ECE R43 can be added to the test sequence as well. |
