A new road map visualization method at window shield display for vehicle driver is proposed. Road structure ahead of a vehicle is shown by CG line segments at the upper area of driver view in augmented reality fashion. Road line segments are virtually placed as if they are lifted up in the sky. By our new visualization method, the rendered CG does not occlude objects and roads that are crucial for drivers. Yet the drivers can easily understand the road map because the road line segments in the sky has vertical correspondence with the road on the ground.

This paper proposes a new visual aid for a driver who is searching a vacant parking space in a congested parking lot. In such a situation, the driver may want to know the states of parking spaces and behaviors of other vehicles. However, this information may not be easily obtained because of the blind spots caused by parking vehicles. In our method, this information is presented on Wind-Shield Display (WSD) in mirrored style in the sky, i.e. the driver can see the information in the upper part of his sight.

We propose a new method for three dimensional localization of vehicle headlights in surveillance camera images at night time. It is impossible to estimate the three dimensional position of a vehicle headlight only by using the position of the headlight in images. We have previously proposed to estimate its three dimensional position based on the spatial constraint of the headlight and its reflection on road surface. Since this method requires an assumption that the reflection on the road is constant, it cannot be applied to the road surface where the reflection property is not constant. To overcome this problem, we propose a method of detecting the reflection position by scanning the images spatio-temporally.

This paper proposes a method to avoid car accidents such as running off the lane or hitting objects by projection-based AR technique that visualizes blind regions in front of a driving vehicle. As the result, smooth passing each other even on a narrow road might be realized.In order to visualize the blind region, our method sees-through the dashboard of a vehicle by using projection-based diminished reality technique, and superimposes the virtual wheel trajectories by using AR fashion.
