Double-planar-array three-dimensional plotting system based on minisatellite platform

Abstract

The invention relates to a double-planar-array three-dimensional plotting system, in particular to a double-planar-array three-dimensional plotting system based on a minosatellite platform, and aims to solve the problems that a processing method of an existing plotting system is complicated, requirements for attitude stability of a satellite platform is high, data cannot be transmitted in real time, processing is inconvenient and the like. The plotting system comprises a house-keeping system, a measurement and control system, an attitude and orbit control system, a power supply system, a thermal control system, a first star sensor, a second star sensor, a data transmission system, a three-axis gyroscope, a foresight planar array camera, a rearview planar array camera and a foresight and rearview optical system in-orbit included angle detection system. The foresight planar array camera and the rearview planar array camera share an imaging and focusing controller; the foresight and rearview optical system in-orbit included angle detection system is used for detecting the changes of a foresight and rearview optical system in-orbit included angle in orbit in real time. The system develops a large-scale double-planar-array three-dimensional plotting research based on a minisatellite in combination with satellite-borne integration and low-orbit operation techniques, reduces the requirements for satellite attitude and orbit measurement accuracy and can realize plotting without the aid of control points.

Description

technical field [0001] The invention relates to a double-sided array three-dimensional surveying and mapping system, in particular to a double-sided array three-dimensional surveying and mapping system based on a small satellite platform that can realize large-scale three-dimensional surveying and mapping. Background technique [0002] The main task of transmission-type large-scale three-dimensional surveying and mapping satellites is to obtain three-dimensional image information of the earth's surface, implement precise positioning of targets, and measure and produce digital topographic maps, digital elevation models and digital image maps. With the single line array technology system, it is necessary to construct the same-orbit or different-orbit stereoscopic images through side swing, which requires extremely high mobility of the satellite platform and high requirements for the attitude stability of the platform. The dual-line array photography mode can achieve continuous...
