AUTOMATED BUILDING DETECTION IN DENSE POINT CLOUD AND UPDATE OF OPEN SOURCE DATA BASES
Dense matching, Building detection Classification Digital Terrain Model openstreetmap point cloud
2018/11/9
In this paper a method of detecting buildings in dense populated city areas using a three-dimensional model, produced by aerial images, is described. Further to the detection of the outline of the bui...

The GEO-ICT is an institutional cooperation project aiming at improving the quality and societal relevance of geospatial and ICT research and education at the Universities of Dar es Salaam (UDSM), Ard...
TARGET GRAPH MATCHING FOR BUILDING RECONSTRUCTION
3D Reconstruction data fusion laser scanner data buildingsz
2016/2/29
We present a building reconstruction approach, which is based on a target graph matching algorithm to relate laser data with building
models. Establishing this relation is important for adding build...

Spatial Data Infrastructure Spatial Database Interoperability
2015/12/11
Croatia is on its way to join the European Union as well as European information society what means that policies, technical standards and operational facilities should be harmonized with European sta...
DATA FUSION FOR BUILDING RECONSTRUCTION FROM MULTI-ASPECT INSAR DATA
InSAR, Multi-Aspect MASAR 3D Reconstruction Building Reconstruction Urban Areas Probabilistic Graphical Model Data Fusion Radargrammetry Compressive Sensing Sparsity
2014/4/24
In this paper we present a novel approach for 3D reconstruction of point clouds based on single baseline Multi-Aspect InSAR (MASAR) data. The point clouds represent an intermediate result to achieve a...
PRIMITIVE-BASED 3D BUILDING RECONSTRUCTION METHOD TESTED BY REFERENCE AIRBORNE DATA
Building Reconstruction LiDAR Optical Imagery Primitive-based Accuracy Evaluation
2014/4/28
Airborne LiDAR data and optical imagery are two datasets used for 3D building reconstruction. By study of the complementarities of these two datasets, we proposed a primitive-based 3D building reconst...
FINDING CUBOID-BASED BUILDING MODELS IN POINT CLOUDS
Point Cloud Segmentation Surface Detection Building Recognition Building Reconstruction
2014/4/28
In this paper, we present an automatic approach for the derivation of 3D building models of level-of-detail 1 (LOD 1) from point clouds obtained from (dense) image matching or, for comparison only, fr...

Pair-Wise Visual Word Tree Efficient Image Re-ranking
2010/12/21
Bag-of-visual Words (BoW) image representation is getting popular in computer vision and multimedia communities.However, experiments show that the traditional BoW representation is not as effective as...
ERMSCT: MPEG-7 Based Didactical AV Courseware Building Tool for Heterogeneous Terminals
MPEG-7 Didactical AV Courseware Heterogeneous Terminals
2010/12/14
Now video courseware is not adaptive to heterogeneous terminals, and its description metadata is too much simple to efficiently and effectively search, store,and evaluate the teaching quality. For muc...
