Abstract

The invention provides an optical remote sensing satellite rigorous imaging geometrical model building method. The optical remote sensing satellite rigorous imaging geometrical model building method comprises the following steps that the geometrical relationship between the image point coordinates of an optical remote sensing satellite and the satellite is determined according to design parameters and on-orbit calibration parameters of an optical remote sensing satellite camera and the installation relation of the camera and the satellite; the shooting position of a satellite image is determined according to the GPS carried by the optical remote sensing satellite, the observation data of a laser corner reflector and the installation relation of the laser corner reflector and the satellite; the shooting angle of the satellite image is determined according to a star sensor carried by the optical remote sensing satellite and the observation data of a gyroscope and the installation relation of the gyroscope and the optical remote sensing satellite, a collinearity equation of all image points of the optical remote sensing satellite is built, and a rigorous imaging geometrical model of optical remote sensing satellite images is formed. The optical remote sensing satellite rigorous imaging geometrical model building method is the basis of optical remote sensing satellite follow-up geometrical imaging processing and application.

Description

technical field [0001] The invention belongs to the technical field of photographic imaging measurement, in particular to a method for constructing a precise imaging geometric model of an optical remote sensing satellite. Background technique [0002] In photogrammetry technology, the rigorous imaging geometric model is closely related to the sensor, and different imaging models are required for different types of sensors. With the emergence of various new aviation and aerospace sensors, from an application point of view, in order to process the data of these new sensors, users need to change their software or add new sensor imaging models to their systems, which brings many problems to users. inconvenient. In addition, rigorous imaging models are not always available because their establishment requires knowledge of sensor physics and imaging mechanisms of airborne and aerospace sensor images. In particular, it is difficult to construct a rigorous imaging geometric model ...
