Mehdi-Souzani1,3, J. Digne2, N. Audfray1, C. Lartigue1,4 and J.-M. Morel3 LURPA, ENS de Cachan, Univ. Our method is designed to cope with line segment extraction for large-scale unorganized point clouds from the real word. A line segment here is defined as the intersection of two half-planes. To extract the line segment, we take into account the point region that is near the straight linear structure. The size characteristics of space debris are an important factor that affects the capturing method. yhexie MIT. INTRODUCTION Edge extraction has attracted a lot of attention … robust Because the accuracy of the segmentation affects the results of the final extraction of the road information, segmentation with high accuracy is required. O12 is the central point of line segment O1O2.Three selected planes T1,T2 and T12, respectively passing through points O1, O2 and O12, are vertical with the line segment O1O2, and d1, d2 … We introduce a fast deterministic technique for plane detection in unorganized point clouds that is robust to noise and virtually independent of parameter tuning.
