Method and system for building information modeling (bim) reconstruction for a piping system

Abstract

A method of BIM reconstruction for a piping system is provided. The method includes: obtaining a point cloud patch with respect to a seed point for the point cloud patch from point cloud data obtained with respect to the piping system, the point cloud patch including the seed point and a first plurality of neighbor points with respect to the seed point; embedding, for each of the first plurality of neighbor points, neighborhood features with respect to the neighbor point to the neighbor point to form a neighborhood feature embedded point cloud patch; generating a point cloud sub-patch including a second plurality of neighbor points from the first plurality of neighbor points of the neighborhood feature embedded point cloud patch, each of the second plurality of neighbor points being determined to belong to a same pipe segment as the seed point using a first machine learning model; determining whether the seed point is a pipe point based on the point cloud sub-patch using a second machine learning model; and determining a pipe centerline point associated with the seed point based on the point cloud sub-patch and based on determining that the seed point is a pipe point. There is also provided a corresponding system for BIM reconstruction for a piping system.
