VECTORIZATION OF ROAD DATA EXTRACTED FROM AERIAL AND UAV IMAGERY
Curvature Classification Road datbases Thinning Topology Vectorization
2016/7/27
Road databases are essential instances of urban infrastructure. Therefore, automatic road detection from sensor data has been an important research activity during many decades. Given aerial images in...
Vectorization, Edge Preserving Smoothing and Dimensioning of Profiles in Laser Scanner Point Clouds
Laser scanning Edge preserving smoothing Profile
2015/12/16
The 3D geometry of an object can be captured very efficiently using a terrestrial laser scanner. By modelling and visualisation of
these 3D data, it is possible to obtain vectorized geometric informa...
ROAD CENTERLINE VECTORIZATION BY SELF-ORGANIZED MAPPING
Semi-Automated Extraction Self-Organization Cluster Analysis Minimum Spanning Tree
2014/12/31
A novel approach to semi-automated road centerline extraction from remotely sensed imagery is introduced. Providing inspiration is Kohonen’s self-organizing map (SOM) algorithm. With IFOV < 2m, road f...
VECTORIZATION OF LINEAR FEATURES IN SCANNED TOPOGRAPHIC MAPS USING ADAPTIVE IMAGE SEGMENTATION AND SEQUENTIAL LINE TRACKING
