경량모델 기반 플랜트 구조물에 대한 동일 형상 판별 방법

초록

Lightweight models are widely used for visualizing and sharing large data in ships and plants. To minimize the file size and increase visibility, this model is mainly composed of triangular elements. Generally, ships and plants are composed of numerous thin metal plates, pipes and beams. These structures contain a large number of identical shapes. In this paper, we propose a method that can exactly determine identical shapes based on a lightweight model. The area and volume are compared for each part. Then, the boundary edges are extracted using triangular elements. The feature points are generated based on edge vertexes, bounding box, principle axis and secondary axis. Finally, the ICP (iterative closest point) is used to determine if thee feature points are in the same position.
