本論文では、複数の視点位置から見た被写体の奥行情報を利用して、仮想的な視点位置から撮像したような画像を生成する方法について提案する。まず、ある視点位置での奥行マップを変換して、仮想視点から見た被写体の奥行マップを生成する。次に、別の視点位置での奥行マップを利用して、仮想視点興行マップのオクルージョン領域を補い、その奥行値を補正する。これに奥行値の補間や平滑化処理をして、実写画像を適切に用いることで仮想視点画像を生成する。本手法により、実際のカメラ位置から離れた視点位置においても、オクルージ...

視線の方向に対応して表示映像が変化する指向性スクリーンを用い, スクリーンを通して対話しているにもかかわらず同一場所で対話している自然な感覚が得られる双方向映像通信用表示撮像装置を実現した。表示映像の視域を制御する技術は大画面化や高精細化の表示技術とは異なり, 自然な感覚を表示映像に取り入れようとする新しい技術である。本論文では, この基本になる指向性拡散板の特質, 指向性スクリーン上の多重映像分離性, 分離性向上のための集光レンズ構造, 投射映像のひずみ補正方法, 多方向撮像方法について...

マルチメディア時代を迎え映像サービスの高度化が期待されている。例えば映像制作の分野では、競技場の中でカメラを設置できない場所など、自由な位置から見た映像を生成したいという要求がある。この要求に対しては従来より、多視点画像を用い、3次元計測技術と画像の射影変換技術を組み合わせた仮想視点画像生成技術が検討されてきた。このような仮想視点画像を生成する場合、仮想視点が被写体に近づくと解像度低下などにより画像が劣化する問題がある。今回我々は、画質評価関数を用い、被写体面の各領域ごとに多視点画像から最...
