SVM-Based Classification of Segmented Airborne LiDAR Point Clouds in Urban Areas

Object-based point cloud analysis (OBPA) is useful for information extraction from airborne LiDAR point clouds. An object-based classification method is proposed for classifying the airborne LiDAR point clouds in urban areas herein. In the process of classification, the surface growing algorithm is employed to make clustering of the point clouds without outliers, thirteen features of the geomet...

Conditional Random Fields for Airborne Lidar Point Cloud Classification in Urban Area

Over the past decades, urban growth has been known as a worldwide phenomenon that includes widening process and expanding pattern. While the cities are changing rapidly, their quantitative analysis as well as decision making in urban planning can benefit from two-dimensional (2D) and three-dimensional (3D) digital models. The recent developments in imaging and non-imaging sensor technologies, s...

Object-based Classification of Urban Airborne Lidar Point Clouds with Multiple Echoes Using Svm

Airborne LiDAR point clouds classification is meaningful for various applications. In this paper, an object-based analysis method is proposed to classify the point clouds in urban areas. In the process of classification, outliers in the point clouds are first removed. Second, surface growing algorithm is employed to segment the point clouds into different clusters. The above point cloud segment...

Integrated Change Detection and Classification in Urban Areas Based on Airborne Laser Scanning Point Clouds

This paper suggests a new approach for change detection (CD) in 3D point clouds. It combines classification and CD in one step using machine learning. The point cloud data of both epochs are merged for computing features of four types: features describing the point distribution, a feature relating to relative terrain elevation, features specific for the multi-target capability of laser scanning...

Urban Landscape Classification System Using Airborne LiDAR

The classification of urban landscape in aerial LiDAR point clouds can potentially improve the quality of largescale 3D urban models, as well as increase the breadth of objects that can be detected and recognized in urban environments. In this paper, we introduce a multi-category classification system for aerial LiDAR point clouds. We propose the use of a cascade of binary classifiers for label...
