Abstract
This paper proposes a reconstruction method of the as-built model of plant piping, where the port point of the fitting is used as the secondary reference point, which represents a connection point between the fitting and its connected pipeline. The connection point between a fitting and a pipeline is a critical point of reference in the as-built model. In this study, a fitting model is registered to the point clouds first by using the state-of-the-art technique, which is based on an iterative closest point (ICP) algorithm and also considers the alignment of the port direction with the connected pipelines. Then, the port points of the registered fitting are considered as connection points, and the nozzle points of the connected pipelines are adjusted along its axis based on the information. After the registration process, which uses the detailed shape of fitting and the directions of adjacent pipelines at the same time, the port point on the registered fitting becomes a better estimate of the connection point compared with the nozzle point of a pipeline detected.

基于点云和端口信息的工厂管道系统建成模型的3D重建

摘要
本文提出了一种工厂管道建成模型的重建方法,该方法将配件的端口点用作次要参考点,该参考点表示配件与其相连管道之间的连接点。配件和管道之间的连接点是竣工模型中的关键参考点。在这项研究中,首先使用最新技术将拟合模型注册到点云,该技术基于迭代最近点(ICP)算法,并且还考虑了端口方向与连接点的对齐方式管道。然后,将已注册配件的端口点视为连接点,并根据该信息沿其轴线调整所连接管道的喷嘴点。完成注册过程后,
