Laser scanning is the latest method to collect 3D spatial data and modelling. It becomes more and more popular in engineering applications such as 3D modeling, deformation analysis, reverse engineering and urban planning. However, laser scanners are not sufficient on their own for 3D surveying and modeling. It should be used together with the photogrammetric data especially in the orientation o...

[ABSTRACT] Photogrammetry is a current method of the data acquisition. However, as a matter of fact, a large manpower and expenditure for making detailed 3D spatial information is required especially in urban areas where various buildings exist. There are no photogrammetric systems which can automatic a process of spatial information acquisition completely. On the other hand, laser range finder...

Imagine a 3D Television system where the user can freely choose his point of view in real-time during watching three-dimensional movies or documentaries. Clearly, one key component to 3D movie making will be the 3D model acquisition process for background models where the actors can be put to life in 3D. In this paper we present a new mobile 3D model acquisition platform to reach this dream. Th...

This article describes an electric vehicle equipped with a laser scanner and a highly accurate absolute positioning system aimed at surveying the geometry of roads. The main advantages of the proposed system with respect to conventional topographic procedures are the possibility of achieving a much higher density of surveyed points and its efficiency while keeping almost the same accuracy—a sta...

Terrestrial laser scanning method is widely used in three-dimensional (3-D) modeling projects. Nevertheless it usually requires measurement data from other sources for full measurement of the shapes. In this study a 3-D model of the historical Mevlana Museum (Mevlana Mausoleum) in Konya, Turkey was created using state-of-the art measurement techniques. The building was measured by terrestrial l...

The high spatial resolution of photogrammetric imaging and the excellent capability of measuring the 3D space by laser scanning bear a great potential if combined for both data acquisition and data compilation. One field of the Christian Doppler Research Laboratory at I.P.F. for “Spatial Data from Laser Scanning and Remote Sensing” focuses on exploiting this potential, in particular in terrestr...

Abstract In this paper, a three-dimensional laser scanner was used to monitor the displacement of retaining structures for excavation, including ring beam and reinforced soil mixing wall (SMW) at an open excavation site. Eight scans were taken before after excavation. Three-dimensional point clouds produced with these are registered analyzed determine displacements structures. Cloud Mesh (C2M) ...

We have developed a new concept of empirical calibration scheme for airborne laser scanner (ALS) intensity by means of portable brightness calibration targets, which can be laid out in the flight target area. The accurate radiometric calibration of these targets is based on laboratory measurements with CCD-based laser backscatter instrument and terrestrial laser scanner reference measurements i...

Laser scanners are widely used in mobile robotics localization systems but, despite the enormous potential of its use, their high price tag is amajor drawback, mainly for hobbyist and educational robotics practitioners that usually have a reduced budget. This paper presentes the modeling and simulation of a hacked Neato XV-11 Laser Scanner, having as motivation the fact that it is a very low co...

The filtering of a digital situation model (DSM) containing points located on vegetation and buildings to a digital height model (DHM) is depending upon the structure of the objects not belonging to the bare ground. The limitation of an automatic global filtering of a DSM as a compromise between the different object classes is shown. Based on an automatic segmentation for each different class t...
