Abstract (in Japanese) (See Japanese page) 
(in English) Recently it becomes much more popular and active to make character animations. But there is a problem that it's not so easy for novice users to represent reasonable motions of human characters. In this paper, we propose a 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, converting 3D coordinates of the feature points into a sequence of motion blocks, and then calculating 3D motion data. By using the motion blocks, we can easily add some emphasis to the partial motions of a human character, and make expressive and attractive human motion data. Our motion estimation system makes it easier to produce character animations, and leads to increase the number of young people who will support the contents industry in Japan.
