The reconstruction of the textured 3D models seems to be very important in almost all the industrial and the engineering fields. These models will aid in defining the problems and consequently finding suitable solutions. In some cases, the final solution could be also simulated on the computer before the applying on the real site. Recently, the laser scanning technology is widely used in captur...

The paper describes a fully autonomous relative navigation solution for urban environments (indoor and outdoor). The navigation solution is derived by combining measurements from a two-dimensional (2D) laser scanner with measurements from inertial sensors. This derivation relies on the availability of structures (lines and surfaces) within the scan range (80 m depth, typically). Navigation here...

The article introduces two three-dimensional rebuilding methods in the Roman necropolis of the Ponte della Lama in Canosa di Puglia, constituted by a cemetery complex with characteristics which do not find any match in other Apulian funeral contexts: the articulation in open sky structures and underground rooms made up by catacombs and small hypogea, with continuity of usage for at least five c...

Accurate vehicle localization in forest environments is still an unresolved problem. GPS has obvious limitations in dense forest, and has to be mixed with other techniques to provide satisfying solutions. One possible way is to localize the vehicle relative to trees detected around the vehicle. The rst step to implement this method is is to nd reliable methods to detect trees, and also to match...

In this paper, we explore the potential capabilities of new laser scanning-based method for direction determination. The method for fully coherent beams is extended to the case when interference pattern is produced in the turbulent atmosphere by two partially coherent sources. The performed theoretical analysis identified the conditions under which stable pattern may form on extended paths of 0...

This article discusses ways of measuring accuracy of a laser range finder (LRF) using a specially designed calibration cube (with 3D calibration marks) in the context of a particular application (i.e., measuring volumes). We also compare (by means of experiments) two alternative volume estimation methods.

The use of robotic systems, especially multi-rotor aerial vehicles, in the documentation historical buildings and cultural heritage monuments has become common recent years. However, teleoperated systems have significant limitations encouraging ongoing development autonomous unmanned vehicles (UAVs). platforms provide a more accurate safe measurement distant difficult to access areas than their...

For several years, our research group has been developing methods for automated modeling of 3D environments. In September, 2002, we were given the opportunity to demonstrate our mapping capability in an underground coal mine. The opportunity arose as a result of the Quecreek mine accident, in which an inaccurate map caused miners to breach an abandoned, water-filled mine, trapping them for seve...
