Quality Analysis and Correction of Mobile Backpack Laser Scanning Data
Backpack laser scanning systems have emerged recently enabling fast data collection and flexibility to make measurements also in areas that cannot be reached with, for example, vehicle-based laser scanners. Backpack laser scanning systems have been developed both for indoor and outdoor use. We have developed a quality analysis process in which the quality of backpack laser scanning data is eval...
متن کاملAdaptive Filtering of Aerial Laser Scanning Data
Filtering non-terrain points from raw laser scanning data is the most important goal to improve productivity in DTM generation. Filtering algorithms are built on assumptions about what discriminates terrain points from points on other objects (e.g. buildings and vegetation). In most cases, a single measure is used to accept or reject points. In this paper a three-stage raw data classification a...
متن کاملAutomated road markings extraction from mobile laser scanning data
Road markings are used to provide guidance and instruction to road users for safe and comfortable driving. Enabling rapid, cost-effective and comprehensive approaches to the maintenance of route networks can be greatly improved with detailed information about location, dimension and condition of road markings. Mobile Laser Scanning (MLS) systems provide new opportunities in terms of collecting ...
متن کاملPhotorealistic Building Reconstruction from Mobile Laser Scanning Data
Nowadays, advanced real-time visualization for location-based applications, such as vehicle navigation or mobile phone navigation, requires large scale 3D reconstruction of street scenes. This paper presents methods for generating photorealistic 3D city models from raw mobile laser scanning data, which only contain georeferenced XYZ coordinates of points, to enable the use of photorealistic mod...
متن کاملUrban accessibility diagnosis from mobile laser scanning data
In this paper we present an approach for automatic analysis of urban accessibility using 3D point clouds. Our approach is based on range images and it consists in two main steps: urban objects segmentation and curbs detection. Both of them are required for accessibility diagnosis and itinerary planning. Our method automatically segments facades and urban objects using two hypothesis: facades ar...
