Although well established, digital photogrammetry continues to change. More sources offer imagery which can be treated photogrammetrically. Users need improved scanner performance as they attempt to offset costs by feeding clusters of workstations or establishing bureau services; increased speed, variable pixel size, use of roll film and “on the fly” dodging are desirable scanner characteristic...

Within the paper the potential of combining terrestrial laser scanning and close range photogrammetry for the documentation of heritage sites is discussed. Besides improving the geometry of the model, the integration aims on supporting the visual quality of the linear features like edges and cracks in the historical scenes. Although the laser scanner gives very rich surface details, it does not...

Environmental monitoring through the method of traditional ship sampling is time consuming and requires a high survey cost. This study uses an empirical model, based on actual water quality of total suspended solids (TSS) measurements from the Prai River estuary Penang, Malaysia, to predict TSS based on optical properties of digital camera imagery. The proposed algorithm is based on the reflect...

Stereo-photogrammetry involves the use of pairs of cameras to extend standard photographic methods by recovering depth information through triangulation (Ayoub et al. 1998). The resulting data consist of a point-cloud of threedimensional observations, providing a digital representation of the surface of the object of interest. The number of observations can typically be many thousands, providin...

This paper presents an efficient and low-cost approach for energy analysis of road accidents using images obtained using consumer-grade digital cameras and smartphones. The developed method could be used by security forces in order to improve the qualitative and quantitative analysis of traffic accidents. This role of the security forces is crucial to settle arguments; consequently, the remote ...

Abstract This paper designed a three-dimensional digital interactive platform, which takes power supply module, image data acquisition control transmission module and ESAM as the main hardware makes it feasible to realize transmission, multiple acquisition, platform process control, encryption decryption, identity authentication. Then, through relative orientation element calculation, model poi...

The internet hype for aerial and satellite images, kicked off by Google (Google Earth), Microsoft (Virtual Earth), and others, is giving the Photogrammetry, Remote Sensing, and GIS markets a tremendous exposure. Making the complete land coverage of Earth in the shortest time could only be achieved by satellite imagery. However, the growing demand for more and ubiquitous details in urban and dev...

The paper describes an application of close-range photogrammetry in the study of the human hand for propulsion in competitive swimming. The study involved the capture of 3-D surface data and modelling of a real and a replica hand. Both real and replica models were used in computer simulation to determine the propulsion parameters for high performance swimming. Custom-made control frame was used...

This paper discusses a quality control system developed to be applied to the digital photogrammetric process for Brazilian spatial data production. The developed quality control system is directed to aerial surveying companies and at same time it can be used as guidelines for specifications for photogrammetric products like aerial triangulation, DTM, orthophoto and mosaic generation, data colle...

Today, 3D models are used in a wide variety of fields. The medical industry uses detailed models of organs. The movie industry uses them as characters and objects for animated and real-life motion pictures. The architecture industry uses them to demonstrate proposed buildings and landscapes. The engineering community uses them as designs of new devices, vehicles and structures as well as a host...
