High Precision Georeferencing using GPS/INS and Image Matching

چکیده
The registration and geometric recti cation of airborne scanner imagery is an essential prerequisite for the processing and analysis of this type of images. The Digital Photogrammetric Assembly (DPA) is an airborne camera consisting of three pan-chromatic line arrays for stereo imaging and four line arrays for multi-spectral imaging. For georeferencing the sensor system is completed by a module consisting of a di erential GPS receiver con guration and an Inertial Navigation System (INS). Additionally, due to the along-track stereo capability of the camera error terms for position and attitude can be estimated by photogrammetric constraints utilizing ground control points and corresponding image points. In order to get a high accuracy position and attitude are determined by integrating all available information (GPS, INS and stereo image data). Within the article the geometric processing of the high precision and high resolution scanner imagery will be described and results of the performed test ight in October 1996 will be presented.

Image Orientation by Gps and Ins
This paper deals with GPS and INS for georeferencing data collected by airborne imaging sensors. It goes through the basic features of GPS and INS and how they can be integrated to give positions and attitudes with higher precision and reliability than either system can achieve alone. Some simulations using GPS/INS orientation and aerial images have been done. The result shows that GPS and INS ...

Over the past decade, airborne hyperspectral systems have shown remarkable performance in identifying and classifying a variety of ground objects, such as differentiating between minerals, vegetations, artificial materials, water, etc. Though the hyperspectral imaging market is still relatively small, yet it is steadily growing. Currently, most of the high performance systems are of the pushbro...
متن کاملAutomatic Georeferencing of Aerial Images Using High- Resolution Stereo Satellite Images
For airborne surveys, direct georeferencing has become the primary source for EOPs (Exterior Orientation Parameters) determination since integrated GPS/INS (Global Positioning System/Inertial Navigation System) systems were introduced. However, there is still need for alternative indirect georeferencing since there are remote, inaccessible areas that lack a geodetic infrastructure and thus GPS/...
متن کاملAn Automated Real-time Image Georeferencing System
To provide rapid analysis for the ongoing status of emergency, the captured aerial images must be georeferenced to the same coordinate system as the existing spatial data in real-time. This study presents a development of an automated real-time image georeferencing which involves a novel image matching and simultaneous AT. We implemented a reliable fast-and-automated image matching based on the...
