| Abstract(in English) | The primary education of graphics for visually impaired students is important. However, the students do not have sufficient educational materials. This paper proposes an image-based recognition method of triangles drawn by Lensen Drawing kit, which is composed of a hook-and-loop fastener board and a pen equipped with woolen yarns on a reel. First, by use of the RANSAC technique, triangles are roughly fitted to feature points coming from woolen yarns on the fastener board. Then, the triangles are precisely fitted to the feature points on the basis of evaluation of the fitting errors and the areas of the triangles. Several experimental results are shown. |
