摘要
剖视图处理能够有助于更好地理解视图,提高三维重建的效率。基于对剖视图自身特点的分析,提出了三维重建中对剖视图的处理算法,即通过剖视图信息的智能提取生成基元体,将基元体同由视图轮廓生成的参照体进行布尔运算,从而得到最终的目标体。算法能够处理包括全剖视图、半剖视图以及平行剖视图在内的剖视图,最后给出了应用算例以验证算法的可行性。
Through providing extra information,cutaway view aids engineering view understanding and accelerates the 3D reconstruction process.This paper proposes a processing algorithm in 3D reconstruction based on the analysis of cutaway view features： to use the cutaway view information to intelligently fetch the basic entity,then to conduct Boolean operation on the basic entity and the reference object generated from view silhouette,and in this way to get the target object.The algorithm can process full cutaway views,half cutaway views and parallel cutaway views.Examples are provided to identify its feasibility in the paper.
