| Outline of Final Research Achievements |
Photogrammetry technology uses photographs of objects. By verifying the shooting method, camera settings, lighting, etc., we were able to derive the basic data for taking the optimum photo for photogrammetry.
The success or failure of photogrammetry depends not only on the development of applications but also on the photographs prepared. As a result, research results useful for improving photogrammetry were obtained. In order to utilize the obtained 3D data of the human body in the field of expression, I thought that it was necessary to verify the data browsing from the creator's point of view. Optimal speed for rotation and movement by mouse operation, wide-angle and telephoto distortion peculiar to camera eyes. We verified the operation feeling of 4D data by adding the time axis to 3D data, and derived the optimum viewing environment.

| Academic Significance and Societal Importance of the Research Achievements |
人間の動きの一瞬を切り取り、オリジナルのキャラクターに置き換え、それを誇張させ、静止画として描く。そういった創作活動はプロアマ問わず一般化している。しかし、人体の動作の一瞬を立体として捉える技術や環境は未だ発展の途上といえる。本研究では、まず、フォトグラメトリー技術を使って人体の動作の一瞬を３Dデータとして取得する上で、最良の測量結果が得られる写真撮影方法を検証し、アプリケーションに依る事の無い、写真と計測結果の相関関係を導きだせた。
また、そのデータを専門的な知識がなくとも、任意に調整できるWEBブラウザを開発し、創作者がストレスなく利用できる３Dデータ閲覧環境の考察を行った。
