Many automated processes in digital photogrammetry such as relative orientation of a stereopair of aerial images or a derivation of a digital terrain model (DTM) are based on image matching. Several approaches to image matching have been developed. In this paper, attention is paid to area based matching. Using of MATLAB in procedures of finding parameters of exterior orientation of an aerial im...
Databases created for various user applications require different types of geometrical and thematic data. The physical shape, volume, and texture of spatial objects are usually requested for objects concerned with such areas as, architecture, archaeology, medicine, or industry. For many years, wide range of close range systems have been used for acqisition of the source data. In the last decade...
The advancement in digital photogrammetry has made photogrammetric technique become simpler, faster and lower cost. Currently, this method is quite popular in covering small and large area. This study examines the use of digital camera of high resolution in capturing aerial photograph based on unmanned aerial vehicle (UAV) as the airborne platform. The study area covered is the area of Universi...
Point based co-linearity is an essential conception in Photogrammetry. But point in photogrammetry means only physical or visible points, such as dots, cross points and corner point etc. Especially in the stage of either analogue or analytical, even digital photogrammetry, the main primitive feature, which can be measured by human operator, is physical point. It can be referred to as Point Phot...
The digital documentation of cultural heritage is receiving much attention in the last few years and 3D modeling of objects or sites is one of the main research topics in this field. Many improvements have been done in the generation of digital models of cultural heritage, concerning range sensors and image based modeling. But there are still a lot of open questions and problems in deciding whi...
ABSTRACT In the last decade, archaeologists have been using human-occupied interactive digital built environments to investigate human agency, settlement, and behavior. To document this evidence, we provide here one method of conducting drone-based photogrammetry GIS mapping from within these spaces based on well-established methods conducted in physical landscapes. Mapping is an integral part ...
Orthoimage and orthomosaic production has traditionally been a sequential process with many steps. With digital photogrammetry a part of the steps have been automated, but still the process requires a lot of operator effort. Now that digital cameras are entering the market and the number of images to be processed is increasing there is a clear need to automate the whole workflow as much as poss...
JET (Joint European Torus) Joint Undertaking is currently planning to install its new Gasbox Divertor remotely. In line with JET’s policy and philosophy, it was decided to survey the divertor structure remotely to confirm its position, shape and integrity prior to installing the new tile configuration. A survey to metrology standards with sub-millimetre accuracy is required. While remote survey...
