Machine Vision and Photometry Inspect Automotive Symbols

Critical to the safety of any vehicle are its lighted components. Illuminated gauges, buttons, and icons communicate vital information to the driver and facilitate safe vehicle operation — in any ambient light or environmental condition. These indicators must be clear, legible, and instantly recognizable whether the vehicle is bathed in bright sunlight or surrounded by utter darkness.

Quality of backlit symbols is determined equally by their brightness, color, and uniformity of illumination as it is by their dimensional integrity. Read an article to learn how photometric capabilities (for measuring brightness and color) and computer vision capabilities (for evaluating shape and defects) come together to provide the ultimate visual inspection solution for automotive symbols.
