Unmanned Aerial Vehicles (UAVs) have become an essential photogrammetric measurement as they are affordable, easily accessible and versatile. images captured from UAVs applications in small large scale texture mapping, 3D modelling, object detection tasks, Digital Terrain Model (DTM) Surface (DSM) generation etc. Photogrammetric techniques routinely used for reconstruction UAV where multiple of...

Scanners are necessary for retrieving digital information from analogue imagery. This paper discusses their geometric and radiometric performance, as input devices for softcopy photogrammetric systems. A classification and overview of scanners, their major technical characteristics, and their development over the last years are given. Some important scanner aspects, including illumination, dyna...

Recent technology developments provide new solutions for high-resolution image acquisition for photogrammetric applications. These cameras are based on large CCD-matrices as well as CCD-line sensors and fulfill both: large field of view and high spatial resolution. Singleor multi-line cameras have been designed for spaceborne, airborne and terrestrial scanners to provide high-resolution wide an...

Network orientation is a fundamental step in image-based 3D measurement. This paper aims to offer insights into network orientation by considering developments in analytical close-range photogrammetry during its evolution from a film-based to digital image-based measurement technology suited to full process automation. A brief mathematical background to orientation models derived via perspectiv...

One of the important stages in the implementation of a GIS is referred to preparation of data to be entered to the system. To produce spatial data for entering to GIS using photogrammetric techniques, common and current method is to utilize photogrammetric and GIS systems individually (off-line procedure). Preparing spatial data on the basis of the mentioned method has a lot of problems, such a...

The consequent way to complete the digital line in photogrammetric processing is to perform digital data acquisition. Since digital frame cameras for photogrammetric purposes will not be available within the next years, digital line scanners will not only fill this gap, they have several advantages, as there is the permanent nadir viewing geometry. At the Institute of Planetary Exploration of t...

Tangible objects are actual that can be touched and have a physical form. Therefore, the existence of tangible cannot separated from potential damage even disappearance. At same time, an essential source research historical needs to preserved. With development technology, recorded in digital forms, 2D Documentation, such as photos videos, increasingly sophisticated technology makes object recor...

Creating virtual environment models often requires geometric data from range sensors as well as photometric data from CCD cameras. The model must be geometrically correct, visually realistic, and small enough in size to allow real-time rendering. We present an approach based on 3D range sensor data, multiple CCD cameras, and a colour high-resolution digital still camera. The multiple CCD camera...

The present study investigated double sampling with regression estimators as a quest for efficiency and effectiveness in forest inventory in Namibian woodlands. Auxiliary data used were obtained from Standard QuickBird satellite scenes (phase 1) for Hans Kanyinga Community Forest from October and November 2004 covering an area of 12,107 hectares, amplified with terrestric data (phase 2) of 2002...
