Innovative measurement technology for head-up displays
HUD TESTING SYSTEMS
GEFASOFT has been developing windshield test benches and end-of-line testing systems for Head-Up Displays (HUD) in the automotive industry since 2003. Our vision-based systems support vehicle and windshield manufacturers worldwide in the testing, adjustment, and quality assurance of modern HUD technologies.
Our measurement techniques enable the acquisition of quality-relevant image parameters as well as the automatic correction and calibration of virtual image displays directly in the vehicle or during the windshield production process.

Testing, calibration, and automatic correction
FUNCTIONAL PRINCIPLE
OF HUD TEST BENCHES
GEFASOFT HUD testing systems capture quality-relevant image parameters of the virtual HUD image directly in the vehicle or during windshield production. Using state-of-the-art image processing systems, distortions, positional deviations, and geometric errors are automatically detected and analyzed.
Based on the measurement results, correction values can be transmitted to the HUD projector. This allows both positional deviations and geometric distortions (warping) to be corrected automatically, ensuring a true-to-original display of driver information.
Precision for safety-relevant driver information
ABOUT HEAD-UP DISPLAYS
Head-Up Displays (HUD) project driver-relevant information such as speed, navigation, or warnings directly onto the vehicle’s windshield. In addition to static information, modern systems also display contact-analog augmented reality (AR) content such as lane guidance, distance information, or collision warnings directly within the real environment.
To ensure this information is displayed with precise positioning, the projector, optics, and windshield must be perfectly matched. Even the smallest deviations can lead to distortions, ghost images, or incorrect positioning, thereby affecting perception and driving safety.
GEFASOFT develops high-precision windshield test benches and end-of-line testing systems for this purpose, which automatically detect and correct such deviations and ensure reliable HUD display.
Component testing through to final vehicle end-of-line testing
VARIANTS OF GEFASOFT HUD MEASUREMENT TECHNOLOGY
Windshield test benches for component inspection
Fully automatic testing of HUD components directly at the glass manufacturer. Optical properties and quality-relevant image parameters of the windshield are precisely recorded and tested.
- Integration into production lines or manual operation possible
- Variants for testing AR and static displays
Adapter sets for windshield test benches
Using adapter sets, test benches are flexibly adapted and equipped for different windshield geometries and windshield models.
- Flexible adaptation to different vehicle models
- Switching between different windshield types in one test bench
Integrative vision kits
for end-of-line inspection
Combination of camera system, calibration unit, industrial PC, and software solution for testing and calibrating complete HUD systems directly after vehicle assembly within the production line.
- Testing the interaction between projector and windshield
- Automatic correction of positional deviations
- Detection of distortion effects and optimization via warping
Mobile HUD calibration system smartBEMI
Compact, handheld testing system for flexible HUD measurements and calibrations during end-of-line inspection under industrial conditions.
- Mobile and wireless HUD testing
- Automatic correction of image distortions (warping)
- Flexible measurement and calibration directly on the vehicle
