Head-up displays (HUDs) pose unique measurement challenges for manufacturers, who must account for projected image luminance, contrast, and clarity regardless of ambient conditions, virtual image positions, or focal distances on an infinite viewing plane. Comprehensive HUD testing requires both photometric (light data) and dimensional (spatial data) measurement combined to ensure the accuracy of information conveyed to a vehicle operator within a rapidly changing, real-world environment. Part of the Radiant Vision Systems TrueTest™ Software family, the TT-HUD module provides all of the benefits of TrueTest Software to efficiently perform light, color, and dimensional measurements with specific tests used to evaluate the quality of augmented projections, such as those emitted by head-up display (HUD) systems. A comprehensive HUD test solution from Radiant combines the TT-HUD application-specific software module, and a ProMetric® Imaging Colorimeter or Photometer with 200 mm electronically-controlled lens to perform rapid, automated visual inspection of head-up displays. TT-HUD uses a ProMetric imaging system to test all HUD characteristics simultaneously, capturing and processing data much faster and more consistently than a spot measurement device or machine vision system alone or combined. In a single hardware/software system, TT-HUD can be used to evaluate all visual aspects of the HUD system as well as test to the specific parameters documented in automotive standards. Comprehensive HUD Test Suite Tests for HUD quality include photometric measurements used to evaluate properties of light (brightness, contrast) as well as spatial measurements used to evaluate
