Satellite positioning systems such as GPS and GLONASS have created significant changes not only in terms of spatial information but also in the construction industry. It is possible to execute a suita...
Considerable research attention has been given to close-range videometric systems for vision-based, three-dimensional object measurement over recent years. These systems have to demonstrate high speed...
Modern, integrated GPS/INS-based direct orientation systems, combined with multi-sensor imaging hardware such as digital cameras and laser ranging devices, allow the simultaneous collection of indepen...
A stereo matching algorithm is developed for object surface construction. The matching problems are addressed by the integration of signal and feature matching. The innovative strategy arises within t...
An important step for processing airborne Light Detection And Ranging (LiDAR) data is point cloud filtering. Points striking on vegetation and man-made objects and low points (points significantly l...
A new method is presented here, which allows for the construction of triangular surfaces from three-dimensional data sets, such as 3D image data and/or numerical simulation data that are based on re...
As three-dimensional range scanners make large point clouds a more common initial representa-tion of real world objects, a need arises for algorithms that can efficiently process point sets. In this p...
This paper describes a method for extracting surfaces from multi-material CT (Computed Tomography) data. Most contouring methods such as Marching Cubes algorithm assume that CT data are composed of on...
The data provided by LIDAR systems are presented in a dense, accurate three-dimensional form without point classification, such as buildings, trees roads, terrain, etc. The principal objective of th...
