Various versions of LIDAR scanners (satellite-borne, airborne, and terrestrial) are perceived as fast and reliable technologies for direct acquisition of spatial data about the objects of interest. Compared to other measurement methods (e.g., photogrammetric manipulation of imagery), the equipment used for such scanners is still multi-part, bulky, and expensive. Moreover, ground-based LIDAR sca...

Mobile mapping system is a close range photogrammetric system proved to be useful in many GIS applications. Whenever an area needs to be surveyed, a van equipped with all the necessary instruments and sensors travels into that area and takes a series of images of the objects and collects other information related to each images. The data is displayed on the workstation monitor. Through the inte...

nowadays, the subject of vision metrology network design is local enhancement of the existing network. in the other words, it has changed from first to third order design concept. to improve the network, locally, some new camera stations should be added to the network in drawback areas. the accuracy of weak points is enhanced by the new images, if the related vision constraints are satisfied si...

This paper is a summary of a student internship with English Heritage's Photogrammetric Unit. During this placement affordable solutions for heritage close-range photogrammetric measurement were examined. Topcon's Image Surveying Station PI-3000 photogrammetric software was used on a project to record carvings found on one of the stones at Stonehenge. Analysis of this carving (and others) is es...

The use of non-metric digital cameras in close-range photogrammetric applications and machine vision has become a popular research agenda. Being an essential component of photogrammetric evaluation, camera calibration is a crucial stage for non-metric cameras. Therefore, accurate camera calibration and orientation procedures have become prerequisites for the extraction of precise and reliable 3...

Current Multi-View Stereo (MVS) algorithms are tools for high-quality 3D model reconstruction, strongly depending on image spatial resolution. In this context, the combination of Super-Resolution (SR) with image-based reconstruction is turning into an interesting research topic in photogrammetry, around which however only a few works have been reported so far literature. Here, thorough study ca...

Nowadays, optical sensors are used to digitize sculptural artworks by exploiting various contactless technologies. Cultural Heritage applications may concern 3D reconstructions of sculptural shapes distinguished by small details distributed over large surfaces. These applications require robust multi-view procedures based on aligning several high resolution 3D measurements. In this paper, the i...

This work describes the use of genetic algorithms in the design of photogrammetric networks. A system made for this purpose EPOCA (Evolving POsitions of CAmeras) is presented. With the system, a photogrammetric network can be designed using three-dimensional CAD-models of the object. The system provides the attitude of each camera in the network, taking into account the imaging geometry of the ...
