An Approach to Building Grouping Based on Hierarchical Constraints
Building generalization building grouping hierarchical constraints Gestalt factors minimum spanning tree
2015/12/2
Building generalization is one of the difficult operations in automated map generalization. It usually consists of two consecutive steps, i.e. dividing buildings into groups (also called building grou...
A Database Approach to Very Large LIDAR Data Management
LiDAR data Octree Quadtree Local KD tree Display precision
2015/11/20
This paper presents an approach to realizing LiDAR data management in DBMS. We use octree to partition data space, and build a local KD tree at each octree’s node. In data organization, we take precis...
Bayesian Model Updating Approach for Systematic Damage Detection of Plate Type Structures
Autonomous Landslide Monitoring System based Wireless Sensor Networks
2015/6/30
This paper presents a model-based monitoring framework for the detection of fatigue-related crack damages in plate-type structures commonly seen in aluminum ship hulls. The monitoring framework involv...
