本研究では，車載カメラ映像を用いた運転者支援に注目する．その際，同じ道路で撮られた過去の映像中の対応するフレームを求める事が可能になれば，様々な用途に使うことができると考えられる．そこで本稿では，高精度な現在と過去の車載カメラ映像中のフレーム間対応付け手法を提案する．同じ道路で撮られた映像同士の対応付けであっても，走行は全く同じ速度・軌跡ではないため，単純な画像照合による対応付けは困難である．そこで，まず現在と過去のフレーム間で対応点を求め，それらからフレーム間の基礎行列を求める．次に，基礎行列から求めたエピポールの位置に基づくフレーム間の距離を定義し，この尺度を用いたDP マッチングにより，フレーム同士を対応付ける．実際の車載カメラ映像を用いた評価実験の結果，提案手法の有効性を確認した．

We propose a visibility estimation method for traffic signs considering temporal environmental changes, as a part of work for the realization of nuisance-free driver assistance systems. Recently, the number of driver assistance systems in a vehicle is increasing. Accordingly, it is becoming important to sort out appropriate information provided from them, because providing too much information may cause driver distraction. To solve such a problem, we focus on a visibility estimation method for controlling the information according to the visibility of a traffic sign. The proposed method sequentially captures a traffic sign by an in-vehicle camera, and estimates its accumulative visibility by integrating a series of instantaneous visibility. By this way, even if the environmental conditions may change temporally and complicatedly, we can still accurately estimate the visibility that the driver perceives in an actual traffic scene. We also investigate the performance of the proposed method and show its effectiveness.

In order to estimate accurate attitude of mobile robots and　vehicles, we propose a hybrid system which combines a lowcost　monocular camera with a gyro sensor. A gyro sensor has　drift errors that accumulate over time. On the other hand, a　camera cannot obtain the rotation continuously in the case　where feature points cannot be extracted from images, although　the accuracy is better than a gyro sensor. To solve　these problems, we propose a method for combining these　sensors based on an Extended Kalman Filter.
