| 3D scanning and model-based
reconstruction techniques, which can rapidly acquire depth data on a
real object's surface, are prevalently used in 3D computer animation
However, Jittering on scanned models or lack of details on model-based
usually unavoidable. By contrast, photometric techniques, such as
shape-from-shading(SFS), provide more fidelity in details, but they are prone to distortion in
In this project, we plan to develop a more reliable SFS method and take
advantages of the abovementioned methods.
By combining the triangulation positioning and photometric methods, the
accuracy of the 3D reconstruction system can be improved. Furthermore, we also
work on advanced user interfaces for 3D modeling.
