We are developing high-performance bumper components capable of achieving a high level of both aesthetic quality and sufficient millimeter-wave transparency. To efficiently determine the formulation requirements for the metallic bright materials within the coating that attenuate millimeter-wave, this study constructed the numerical calculation model capable of predicting transmission performance with practical accuracy and identified the factors by which metallic bright materials influence transmission performance.

3D Measurement of the Baseline Direction in Stereo Cameras Using Image Magnification Ratio

Hideaki Kido (Hitachi)･Kota Irie (Astemo)

We propose a method for measuring 3D distances in the reference direction for fisheye stereo camera systems. This method estimates distances using image magnification under the assumption of a planar surface. Numerical simulations and experiments using computer graphics demonstrated that, when the angle of incidence is close to 90 degrees, this method achieves higher accuracy compared to conventional parallax-based measurement methods.

This study investigates the feasibility of a laminated-glass-integrated Mini-LED module for automotive lamp applications. A Mini-LED sample was embedded in laminated glass using a conventional automotive lamination process. Luminance comparison before and after lamination and high-temperature reliability tests were conducted to evaluate process compatibility and durability. The embedded module showed limited luminance change after lamination and satisfied predefined evaluation criteria after reliability testing. These results indicate the applicability of laminated-glass-integrated Mini-LED modules to future automotive lamp systems.

This study investigates the effect of high-definition micro-LED (HD) beam control on camera-based lane detection under nighttime driving conditions. Conventional low and high beam was compared with an HD adaptive lighting system across various road environments. Conventional lighting reduced lane recognition accuracy, particularly on curved roads and near reflective structures that induced glare. In contrast, the HD module enhanced lane visibility through precise light distribution control and maintained more stable recognition performance. These findings suggest that HD adaptive lighting may improve vision-based ADAS perception and enhance nighttime driving safety.
