A template-based reconstruction of plane-symmetric 3D models from freehand sketches

This paper presents a method for reconstructing a 3D model from a freehand sketch. There are two methods used in sketch-based modeling research: gestural modeling and reconstructional modeling. This research involves the reconstructional modeling method of Mitani, which was originally designed for a box-shaped model using a predefined template. Here, this method is improved by leveraging a relational template and a template matching method that extend the range of categories of the reconstructed objects. Sketch preprocessing details are provided and the template-based reconstructional method then uses the sketch preprocessing results to reconstruct a 3D model from a freehand sketch.
