Modeling of 3D scenes has been the defining subject in photogrammetry or remote sensing for more than 100 years, and it is now for about 30 years one of the main subjects in computer vision. There are recently significant paradigm shifts in both areas. Digital imaging reshaped photogrammetry and remote sensing, and active vision (e.g., integrating laser range finder, SAR, or structured lighting...

An experiment was conducted to examine the validity of freely available photo-based 3D scanning software for generating accurate 3D geometry of a vehicle. Currently, 3D vehicle geometry is routinely captured using total station survey equipment, coordinate measuring machines (CMM), laser scanning, or traditional point-based photogrammetry. While these methods produce sufficiently accurate resul...

In last decade, we have witnessed an increased number of publications related to systems that combine laser scanning and closerange photogrammetry technologies in order to address the challenges posed by application fields as diverse as industrial, automotive, space exploration and cultural heritage to name a few. The need to integrate those technologies is driven by resolution, accuracy, speed...

Although there is an unchanged demand for the recording and documentation of the cultural heritage, modern acquisition and analysis techniques are rarely used. The paper shows results of the application of videogrammetry and CAAD for the architectural restitution, contributing thus to the CIPA test “Wagner-Pavillon”. The images were acquired with a S-VHS camcorder, which today are considered to...

This paper investigates the precision and capability of low cost off-line industrial photogrammetry for determination of deformations in aircraft parts. The study concentrates on deformation analysis of an airplane propeller through standard photogrammetric procedures. In this regard, around 100 targets were fixed on the blades of the propeller and imaged from several stations. The left and rig...

A Digital Elevation Model (DEM) represents the height of a patch of terrain. Accuracies of DEMs vary depending upon the requirements of different applications. DEMs have been applied to a wide range of civil engineering and military planning tasks. Besides the conventional methods of creating DEMs, such as photogrammetry and manual field survey, airborne laser scanning and radar interferometry ...

The orientation of laser scanner point clouds is one of the fundamental steps in the process of creating three-dimensional digital representations of existing objects. Orientation is the task of finding the correct positions of two or more point clouds (that only partially represent the object) obtained from different viewing positions, such that the full object in consideration is correctly de...

by far, many stereo-matching techniques have been successfully proposed and applied in digital aerial photogrammetry. however, due to some problems such as large parallaxes, occlusions, geometric deformations, and repetitive patterns in convergent close range images, these methods may not be applicable to the same level of success as that of aerial imagery. in order to overcome these shortcomin...
