安全運転支援において，周囲の道路状況を理解することは重要である．自車周囲を走行する他車両の台数の把握は，道路状況の理解に役立つ重要な情報と考えられる．本発表では，車載カメラ画像中から車両の台数を推定するため，車両部位検出を利用した回帰による車両台数推定手法を提案する．車両を検出して台数を数える手法では，車両のオクルージョンにより検出精度が低下する問題がある．この問題を回避するため，提案手法では車両部位を検出して台数を数えるアプローチを用いる．車両の部位数から台数を推定する場合，車両の台数と部位数の関係は複雑であり，部位数から車両台数を一意に求めることは難しい．そこで，回帰を導入することにより，推定誤差の低減を図る．提案手法の有効性を確認するため，実環境で撮影した車載カメラ画像に対して提案手法を適用して車両台数を推定し，推定精度を評価した．評価の結果，提案手法は平均絶対誤差1.11 台の精度で車両台数を推定可能なことを確認した．

Accurate vehicle positioning is important not only for in-car navigation systems but is also a requirement for emerging autonomous driving methods. Consumer level GPS are inaccurate in a number of driving environments such as in tunnels or areas where tall buildings cause satellite shadowing. Current vision-based methods typically rely on the integration of multiple sensors or fundamental matrix calculation which can be unstable when the baseline is small.

In this paper we present a novel visual localization method which uses a visual street map and extracted SURF image features. By monitoring the difference in scale of features matched between input images and the visual street map within a Dynamic Time Warping framework, stable localization in the direction of motion is achieved without calculation of the fundamental or essential matrices.

We present the system performance in real traffic environments. By comparing localization results with a high accuracy GPS ground truth, we demonstrate that accurate vehicle positioning is achieved.

Crowd analysis using cameras has attracted much attention for public safety and marketing. Among techniques of the crowd analysis, we focus on spatial people density estimation which estimates the number of people for each small area in a floor region. However, spatial people density cannot be estimated accurately for an area far from the camera because of the occlusion by people in a closer area. Therefore, we propose a method using a memory based regression method with images captured from cameras from multiple viewpoints. This method is realized by looking up a table that consists of correspondences between people density maps and crowd appearances. Since the crowd appearances include situations where various occlusions occur, an estimation robust to occlusion should be realized. In an experiment, we examined the effectiveness of the proposed method.
