Fusion of Terrestrial Laser Scanning and Digital Photogrammetry
نویسنده
چکیده
Terrestrial laser scanners are introduced in the market in various construction forms, dispose of various measuring principles and are used in the most different areas of application. Combining the information of the gray-scaled point cloud with the geometry informations of rgb-colored images results in improved possibilities of object interpretation and measurement. The coalescence of both data springs under special consideration of the metric of the measuring image offers possibilities of an enlarged use. The article refers to the hybrid measuring system consisting of 3-D scanner and digital camera, which in the following will be characterized by the expression “image scanner”. A systematic view of market-current systems, their functions and designs will be given. This includes consequences concerning data quality, geo-referencing and in the end object recognition and evaluation process.

متن کاملA field investigation of application of digital terrestrial photogrammetry to characterize geometric properties of discontinuities in open-pit slopes
In order to analyze the slope stability in open-pit mines, the structural parameters of rock mass such as persistence and spatial orientation of discontinuities are characterized through field surveys, which involve spending high costs and times as well as posing high risks of rock toppling and rock fall. In the present work, a new application of terrestrial digital photogrammetry is introduced...
