Evaluating backlit components—such as illuminated controls, instrument panels, and LED light strips—requires a unique measurement approach. The quality of an illuminated component is determined as much by its photometric qualities (brightness, color) as it is by the overall integrity of its illuminated regions (correct shape, free from defects). Accurate measurement requires precise registration of icons and shapes, ensuring that only the illuminated region is used to quantify photometric values and that defects can be detected. While photometric measurement systems excel at light and color analysis, they have traditionally lacked machine vision functionality that enables consistent registration of unique shapes, as well as overall inspection of shape or text quality.
Part of the Radiant Vision Systems TrueTest™ Software family, the VIP™ (Vision Inspection Pack) software license supplements the standard photometric analysis capabilities of TrueTest Software adding registration functionality for unique illuminated regions (backlit icons and shapes) to enable defect detection and accurate photometric measurement.
-- Automated visual inspection of backlit icons, text, and unique shapes; for example: illuminated indicators, buttons and controls, LED-backlit components (functional, accent), instrument clusters, and panels
-- Used to ensure quality of backlit controls and indicators in automotive assemblies, avionics, medical devices, appliances, and electronics
-- Photometric and colorimetric measurement within a region
-- Location and registration of regions for precise measurement and defect detection
