Projecting speed, navigation, and situational data onto the car windshield within the operator’s field of view offers safety and design advantages that have given HUD technology the highest expected growth rate in the automotive market (Source: Mordor Intelligence, Automotive Head-up Display Market – Analysis of Growth, Trends, and Forecast (2018 – 2023)). Introduced in several new vehicles, HUDs are evolving rapidly. With the rise of virtual and augmented reality (VR, AR) in consumer electronics, user expectations regarding projection and holographic displays have set a high bar for HUD design and quality. The opportunity for automakers to gain a competitive advantage by offering fixed-depth, two-dimensional HUDs may be brief. Anticipation is building for next-generation 3D and AR systems, even prior to a widespread commercial rollout of the first integrated HUDs.
With the advent of new HUD systems, equipment used to ensure HUD optical quality (the accuracy and visibility of projected images on the windshield) is likewise facing new demands. HUD measurement must adapt with the incorporation of 3D and AR-HUD systems, which project new types of virtual images, across larger fields of view, and at a range of depths. Responding to these demands, manufacturers are challenged to find measurement systems that can address the evolution of HUD technology.
Having contributed to the development of optical metrology parameters for new international HUD measurement standards (SAE J1757-2 “Optical System HUD for Automotive”), the automotive team at Radiant Vision Systems has adapted solutions for HUD testing to meet the measurement criteria of automotive OEMs and Tier I suppliers, whose products incorporate a range of technologies for traditional and AR HUD including TFT, DLP, and laser-based systems. Radiant ProMetric® imaging colorimeters and photometers feature an electronically-controlled lens that is highly effective at identifying and focusing on an image projected into infinity. This capability enables ProMetric analysis software to provide accurate luminance and chromaticity measurements at any working distance—from traditional HUD projections at two to five meters, to AR-HUD projections as far as 20 meters.
During the upcoming webinar, Radiant International Senior Business Advisor for Automotive applications, Matt Scholz, will present the measurement challenges posed new HUD technology from traditional fixed-depth, two-dimensional projections to AR-HUD and 3D images, and camera-based solutions that are adaptive to imaging requirements for simplified quality testing of HUD optical systems. Scholz will introduce Radiant’s photometric HUD measurement system, review imaging specifications that are beneficial for measurement across HUD systems, and demonstrate HUD image quality tests in Radiant’s new TT-HUD software module.
