Paper Abstract

Georeferenced image, a kind of digital ground image with 3D geographic coordinates, is an important data source of Global Information System (GIS). In constructing georeferenced images and considering its application, the positioning precision of geographic coordinates is a key specification. Remote sensing is a promising method for the data acquisition of georeferenced image. Using an integrated system of airborne remote sensing technique can high efficiently acquire georeferenced image and its geographic coordinates with better precision. In this thesis, that integrated technique and system is introduced first, which consists of laser ranging, whiskbroom imaging, differential global position system, and inertial reference system. Then the effect of each part on the system precision especially elevation precision is analyzed in detail, and the mathematics expression and data result are yielded. Furthermore, for obtaining high positioning precision of georeferenced image, some technical designs and methods are discussed.
