Three-Dimensional Reconstruction of Ancient Chinese Architecture

This paper started with a two-dimensional image of ancient Chinese architecture. Firstly, it detected edge of target to obtain the contour and detected its corner points, which would be used to get contour curve equation. Then a rotating body reconstruction method based on the cross-sectional radius was proposed. It realizes the modeling of 3D rotation. What's more, non-photorealistic rendering of the three-dimensional model was also achieved.
