An Autonomous Ultra-Wide Band-Based Attitude and Position Determination Technique for Indoor Mobile Laser Scanning [PDF]

open access: yesISPRS International Journal of Geo-Information, 2018
Mobile laser scanning (MLS) has been widely used in three-dimensional (3D) city modelling data collection, such as Google cars for Google Map/Earth. Building Information Modelling (BIM) has recently emerged and become prominent.

Urban accessibility diagnosis from mobile laser scanning data [PDF]

open access: yesISPRS Journal of Photogrammetry and Remote Sensing, 2013
In this paper we present an approach for automatic analysis of urban acessibility 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.

A Railway Lidar Point Cloud Reconstruction Based on Target Detection and Trajectory Filtering

open access: yesRemote Sensing, 2022
The traditional railway survey adopts a manual observation method, such as a total station measuring system. This method has high precision, but the amount of data is small, and the measurement efficiency is low.

A Study of Scan Patterns for Mobile Mapping [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
Mobile terrestrial scanning systems automate terrestrial laser scanning. Continous scanning mobile terrestrial systems constantly spin the terrestrial laser scanner and thus combine terrestrial scanning with kinematic laser scanning.

MOBILE LASER SCANNING FOR DETAILED DIGITAL TOPOGRAPHIC MAPPING

open access: yesContemporary Theory and Practice in Construction, 2021
<jats:p>Mobile Laser Scanning (MLS) is a technique characterized by high data acquisition efficiency and level of detail. However, a lot of information contained in the LiDAR point cloud is only implicitly available. Therefore, in order to create a digital topographic map from a large quantity of MLS survey data, it is ...

Freehand Laser Scanning Using Mobile Phone [PDF]

open access: yesProcedings of the British Machine Vision Conference 2015, 2015
3D scanners are growing in their popularity as many new applications and products are becoming a commodity. These applications are often tethered to a computer and/or require expensive and specialized hardware. In this note we demonstrate that it is possible to achieve good 3D reconstruction on a mobile device.

Semi-Automatic Road/Pavement Modeling using Mobile Laser Scanning [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
Scene analysis, in urban environments, deals with street modeling and understanding. A street mainly consists of roadways, pavements (i.e., walking areas), facades, still and moving obstacles.
