This paper presents an approach for detecting primitive geometric objects in point clouds captured from 3D cameras. Our permu- In the fields of 3D modeling, analysis of discontinuities and engineering calculation, surface extraction is of great importance. Primitive objects are objects that are well defined with … Our proposed technique is robust to noise and outliers and can … The need for fast and robust feature extraction from 3D data is nowadays fostered by the widespread availability of cheap … The method is robust to noise in … In typical mobile perception scenarios, 3D LiDARs output a large streaming volume of raw scans in the form of unorganized point clouds. Edge Highlights • A simple and effective ridge valley point recognition method is present, which greatly reduces the number of potential feature points and improves the robustness of the recognition. Two specific neighborhood reconstruction strategies are designed for these two types of points to generate a neighborhood clear of sharp features. Furthermore, we demonstrate the robustness of our approach in the noisier real-world datasets. PPFNet learns local descriptors on pure geome-try and is highly aware of the global context, an impor-tant cue in deep learning. Fast and Robust Edge Extraction in Unorganized Point Clouds @article{Bazazian2015FastAR, title={Fast and Robust Edge … Source code and the dataset of this paper: Fast and Robust Edge Extraction in … As the three typical cases illustrated in Figure 1, the k-neighborhood and PCA-based method (KNN–PCA), which is the most popular normal-estimation method for 3D point-cloud data, always outputs smoothed normals for some edge points of the roofs (Case 1), unreliable normals for noisy ground points (Case 2), and scattered normals for all tree points (Case 3).
