Architectural heritage must be conserved by using contemporary approaches. Conserving the historical buildings depend on appropriate measurements and data related to their life history. At this stage, digital photogrammetric techniques and GIS (Geographical Information System) integration would be one of the best solutions. GIS has a capability to integrate and update graphic and non-graphic da...

The United States Geological Survey (USGS) in cooperation with The Ohio State University (OSU) and Calgary University (CU) have developed procedures and software for the efficient calibration of metric quality aerial cameras; both filmand CCD-based sensors. With the advent of the Global Positioning System (GPS), and its efficient use to position the exposure station of the aerial camera, it bec...

The interdisciplinary work presented here deals with the management of diverse types of information collected during an archaeological excavation, and organized as an XML based data management system. The approach is global, from the consultation of three-dimensional data to simple textual data, and to additional data captured by a digital photogrammetry system called ARPENTEUR, which is now fu...

Airborne photogrammetry is a fundamental technique for producing reliable, geometrically accurate, high-resolution geospatial information. Passive and active digital imaging is rapidly replacing film imaging in photogrammetric data capture. Optimal use of this new technology enables fast data capture, high accuracy, a high level of automation, and a huge increase in applications. The reliabilit...

The paper discusses the use of geometric constraints in a CAD model-based photogrammetric system. The CAD models are represented by CSG (Constructive Solid Geometry) models. The geometric primitives that make up the CSG model are parameterized by their pose and shape parameters. Geometric relations, or constraints, between these primitives are expressed using these parameters. Constraints can b...

This paper is focused on integration between laser scanning data, CAD modelling and photogrammetric data collected during the survey of one façade of the monument called “Quattro Canti” in the historic centre of Palermo. The investigation has been directed to the production of a 3D photorealistic model of the monument. The “Quattro Canti” monument is formed by four cylindrical façades facing th...

For many applications it is important to know how two adjacent parts of a system are located. Measuring outer parameters of parts is relatively simple task. But it is a problem to determine relative attitude of inner surfaces of adjacent parts and to measure given parameters of conjunction. Such applications as manufacturing, dentistry have a need for a solution this problem. A photogrammetric ...
