Abstract

近年,個人による 3DCG アニメーションの製作が盛んになってきているが,ユーザの前に立ちはだがる壁として,キャラクタのモーション作成が難しいという問題がある.本稿では, 2 次元映像を入力とし,映像に映っている人物の動作を推定。モーションデータを出力するシステムを提案する.人物の動作推定は,人物の特徴点 (関節位置) をトラッキングし,その結果と動画像から得られる情報を用いて 3 次元空間における特徴点の座標値を求め,得た座標値から各関節の回転角度を計算することで行う.本システムを用いることで,3DCG アニメーション作成の難しさを軽減することができると考えられる.Recently it becomes much more active to make 3DCG animations. But there is a problem that it is not so easy to make motion of human characters. In this paper, we propose the human motion estimation system. The input of the system is markerless 2D monocular video data, and the output is 3D motion data with a standard format. The human motion estimation process is carried out by tracking feature points (joint positions) of the human body, getting 3D coordinates of the feature points using the results of tracking information of video images, and calculating angle of rotation at each joint using 3D coordinates of the feature points. This motion estimation system makes it easier to produce 3DCG animation.
