چکیده

The proposed approach consists of the following steps: 1. Retrieve the 3D positions of the scatterers from SAR images, i.e. a tomographic SAR inversion. 2. Co-register the 3D point cloud of the SAR scatterers with a reference 3D airborne LiDAR surface model, due to the relative position of the SAR point cloud to the reference point. 3. Co-register high resolution optical image with the reference 3D model, so that each scatterer can be traced in the optical image. 4. Classify the optical image pixels based on its semantic meaning, e.g. geometry, material, and so on. 5. Analyzing 3-D objects in the point cloud based on their semantic class.

Feature Relevance Assessment for the Semantic Interpretation of 3d Point Cloud Data

The automatic analysis of large 3D point clouds represents a crucial task in photogrammetry, remote sensing and computer vision. In this paper, we propose a new methodology for the semantic interpretation of such point clouds which involves feature relevance assessment in order to reduce both processing time and memory consumption. Given a standard benchmark dataset with 1.3 million 3D points, ...

Knowledge-based Object Detection in Laser Scanning Point Clouds

Object identification and object processing in 3D point clouds have always posed challenges in terms of effectiveness and efficiency. In practice, this process is highly dependent on human interpretation of the scene represented by the point cloud data, as well as the set of modeling tools available for use. Such modeling algorithms are data-driven and concentrate on specific features of the ob...

Web-based Framework for Ps-insar Data Interpretation Assisted by Geo-spatial Information Fusion

This study investigates the options of information mining to enhance interpretation of PS-InSAR results of land subsidence analysis. Persistent Scatterer (PS) Interferometric Synthetic Aperture Radar (InSAR) is one of the latest applications of SAR time series data analysis. The detection of coherent point target measurements i.e, persistent scatterers gives an opportunity of measuring sub-cm d...

A novel method for locating the local terrestrial laser scans in a global aerial point cloud

In addition to the heterogeneity of aerial and terrestrial views, the small scale terrestrial point clouds are hardly comparable with large scale and overhead aerial point clouds. A hierarchical method is proposed for automatic locating of terrestrial scans in aerial point cloud. The proposed method begins with detecting the candidate positions for the deployment of the terrestrial laser scanne...

Interpretation of Urban Scenes based on Geometric Features

In this paper we investigate the acquisition of 3D functional object maps for outdoor urban scenes from point cloud data, using techniques which worked reliably for indoor household environments in our previous work[1]. By employing 3D geometry reasoning methods, our approach can successfully segment the important parts of the environment and give semantic annotations to the underlying data poi...
