HDマップ更新に向けたMMS-Probe開発における自己位置推定精度と標識認識精度の向上

抄録

The high-definition (HD) map is widely used in autonomous driving to acquire correct road information during driving. At the same time, the HD map also needs to be updated promptly when road changes happen, such as establishing new traffic signs or the expansion of road lanes. Therefore, building a system that automatically detects road change areas is an essential issue need to be solved. In this paper, we had improved the accuracy of road sign detection then investigated change detection methods. We confirmed a proposed method to correct the position and orientation of the vehicle in real-time using road lanes detected from images with other data.
