【摘要】 STL文件因其简单和通用性好 ,一直作为快速成型领域的准标准。但是由于其本身的缺陷 ,造成切片之后的轮廓信息数据有大量的冗余数据甚至错误。文章针对切片轮廓的不封闭 ,给出了有效的修正算法 ;通过对轮廓信息中冗余数据的分析 ,提出了一种冗余数据的滤除算法。该算法高效简单 ,提高了后续数据处理的效率和成型件的加工质量更多还原

【Abstract】 STL is the criterion in rapid prototyping field because of its simpleness and currency. But for its defection, there are large number of redundancy and error in slice profile data. In this paper an effective modification algorithm is proposed for non-closed slice profile. After analyzing the redundancy of profile data, a filtering algorithm is introduced. This algorithm is simple and effective, it advances the efficiency of later data process and machine quality of part.更多还原
