Extracting Plücker Line and Their Relations for 3D Reconstruction
using indoor structural line and their relations for 3D reconstruction. Second, for the first time, a new strategy from ceiling to floor is applied to overcome the occlusion on the floor. Third, Pl¨ucker coordinate is used to represent indoor structural line and reason the relations of spatial lines to simplify the calculation processes.At present, researches on extracting buildings based on point clouds are still insufficient. To address the issues raised from the state-of-the-art of the classification of laser scanning data, in this paper, instead of directly using low-level features, we carefully investigate the influence of several different feature sets on semantic labeling for Semantic-Based Building Extraction from LiDAR Point Clouds

Building Boundary Point Extraction from LiDAR Point Cloud
Abstract and Figures. Building boundary extraction from LiDAR point cloud data is important for urban planning and 3D modelling. Due to the uneven point distribution, missing data, and occlusionLayout reconstruction is the task of retrieving the layout from a metric representation of the building and can be performed at room or at floor level, starting from 2D grid maps [ 4] or from 3D point clouds [ 5, 6 ]. In this paper, we propose a method that reconstructs the layouts of buildings starting from 2D metric maps.Extracting Structure of Buildings Using Layout Reconstruction

A GIS Pipeline for LIDAR Point Cloud Feature Extraction
To realize that there are two main steps as in [1]: Classification: assign a class to each point in the point cloud dataset. One way is using the PointCNN neural network given that there is sufficient training data. The output is a class for each data point. GIS pipeline: extracting relevant features from classified point cloud data in a usableTo address this issue, this paper proposes to extract structural lines and analyze their relations to obtain the structure lines, which are continuous, anti-occlusion, able to reconstruct indoor space.
