Fast Georeferencing Images Throuth Generalized Photogrammetric Algorithms
نویسنده
چکیده
Traditional photogrammeric workstations for georeferencing images are usually timeand human resource-consuming, input dat a source specific, and lack of flexibility to use in a generalized triangulation problem. These characteristics have made them inadequate to be used in case of emergency. The approach presented in this paper started after Chi-Chi Earthquake of Richter Magnitude 7.3 struck central Taiwan on September 11th, 1999, in response to the situation that we did not have a proper tool to deal as soon and easy as possible with the problem that the Earth surface had been changed, and acceptable data of what it was is still not available even a few months later. In responding the need of a proper tool to deal with, generalized photogrammetic algorithms are developed totally based on geometry to reduce the computing overheads needed to calculate space resection and relative orientation. A hexagonal approach to pattern matching is also provided in this paper to reduce the intensive time spent in the process of feature extraction.

Photogrammetric Application of Spherical Imaging
Spherical imaging is a technical approach of collecting scenery by viewing it through a single perspective. A typical realization of spherical imaging is a panoramic mosaic covering a part of the hemisphere. According to a photogrammetric definition, we introduce here, spherical imaging is an exact central projection explicitly determined by its projection center. They are linear images without...

متن کاملIndirect Georeferencing of Airborne Multi-line Array Sensors: a Simulated Case Study
Multi-line array sensors, carried on airborne or satellite, acquire images with along or across track stereo viewing and are used for photogrammetric mapping at different scales. The main characteristic of the imagery provided by this kind of sensors is that each image line is independently acquired with a different sensor external orientation (position, attitude). If positioning instruments (G...
