POLE-LIKE OBJECT EXTRACTION FROM MOBILE LIDAR DATA
LiDAR Point Clouds Local Roughness Graph Cuts based segmentation Pole-like object detection DBSCAN based point clustering
2016/7/5
Object detection and recognition from LiDAR (Light Detection And Ranging) data has been a research topic in the fields of photogrammetry and computer vision. Unlike point clouds collected in well-cont...
EXTRACTION OF OPTIMAL SKELETON OF POLYGON BASED ON HIERARCHICAL ANALYSIS
Optimal Skeleton Algorithm Hierarchical Structure
2016/3/17
Skeleton is an important 1-D descriptor of polygon and a useful tool for advanced geometric algorithms. However the skeleton that most existing algorithms investigated is the longest one, which is not...
STRAIGHT ROADS EXTRACTION BY FUSION OF SPOKE WHEEL AND REGION GROWING
Semi-automatic road extraction spoke wheel region growing
2016/3/17
Semi-automatic methods are regarded as more practical than automatic methods to obtain and/or update the vector road data. But road tracking methods lose their efficiencies when they are applied to tr...
EXTRACTION OF HORIZONTAL VANISHING LINE USING SHAPES AND STATISTICAL ERROR PROPAGATION
geometrical scene analysis error propagation video processing Hough transformation
2015/8/31
In this paper we address the problem of estimating the horizontal vanishing line, making use of motion statistics derived from a video sequence. The computation requires the satisfying of a number of ...
