A Study on DB Construction for Error Modification of STL Format and Efficiency by Shape Restoration

STL 포맷의 오류수정을 위한 DB 구축과 형상복구에 의한 효율성 연구

This paper recommends the database construction for STL data and the new method of Delaunay's triangulation method in order to decrease volume errors by verifying STL file errors and modifying hole errors. Each vertex for the boundary coordinates of the verified hole errors was analyzed according to the following cases: planes or slow curves, edges, apexes, and rapid curves. In each case, a different modification process was adopted. With this method, most errors resulting from the conversion into the STL data as well as lots of volume errors arising from error modification were decreased.
