-oT-Sim (dynamic scenarios of Optical Brightness Simulation) is a road traffic driving environment simulation (Unreal Engine-based) for autonomous driving verification and advanced safety lamp function verification, incorporating our optical expertise and verification processes. oT-Sim can be used standalone or in combination with our oT-Analyser to perform optical verification and visibility/ readability verification of lighting equipment, such as headlights, taillights, and interior displays. Based on over 20 years of practical experience in high-standard road design, we also possess unique real world road generation know-how that offers excellent cost-effectiveness, and provide real-road 3D models for verification purposes. We can also provide nighttime driving road scenes that are optically verifiable, with dynamic range over those captured by in-vehicle cameras.

• Virtual Reality Related

Measurement at 60 Fps or higher and 4K or higher resolution, allowing accurate luminance data to be obtained, including daytime, nighttime, backlighting, and rainy conditions. By inputting the data recorded into our HALDIS system, the scene can be dynamically displayed indoors with the same brightness as outdoors.

• Optical Measuring Instruments

-HALDiS-C [Luminance Simulator] dedicated to very high contrast scenes (Features) ・Accurate luminance display ・High brightness and ultra-high contrast (contrast ratio of 1 : 5,000,000 or higher) - closed loop real time operation ・Fully automatic calibration function ・Enables not only logic verification but also performance verification for automotive embedded cameras such as ADAS cameras, etc ・Supports LED lighted tunnel scenes, tunnel entrances/ exits, underpasses, variable road traffic signs, and more (Representative application examples) • Camera OTA HILS test bench (HDR cameras also verifiable) • AI algorithm verification • Glare reproduction and night scene compatibility (high brightness + ultra-high contrast) • Wide-angle camera compatibility (using converter lenses)

• Other inspection equipment and devices

HALDiS　Luminance Simulator features two display functions: (1) reproducing outdoor colors and brightness indoors, and (2) outputting the brightness and color values of input data as absolute values. It reproduces outdoor driving data or simulation input results on a 1:1 basis. By inputting lamp design data, users can verify brightness and color, thereby reducing prototype manufacturing costs.
