Abstract

The invention discloses a method and system for realizing inertial space scanning imaging. The method for realizing inertial space scanning imaging comprises the following steps of: obtaining a real-time three-axis attitude of an optical bench relative to an inertial space through gyro integration, error analysis and compensation; establishing an Euler coordinate transformation matrix according to the obtained real-time three-axis attitude of the optical bench relative to the inertial space; and according to an inertial space scanning baseline and a scanning speed requirement, decomposing an inertial space scanning speed vector, and performing decoupling through the established Euler coordinate transformation matrix so as to drive an electromechanical shafting system to move cooperatively . According to the method and the system for realizing inertial space scanning imaging provided by the invention, the search scanning of the inertial space stable baseline is realized, a gyroscopic drift is small, and the gyroscopic speed control is stable.

Description

technical field [0001] The invention relates to the technical field of photoelectric imaging, and in particular discloses a method and system for realizing inertial space scanning imaging. Background technique [0002] Inertial space can be understood as cosmic space. Since the universe is infinite, it is meaningful to describe the movement relative to inertial space with specific reference objects. That is to find objects in the cosmic space with no force or force and the resultant force is zero. They remain absolutely static or move in a straight line at a uniform speed in the inertial space. The frame of reference constituted by them is the inertial frame of reference. [0003] In the prior art, to achieve inertial space scanning and imaging, a three-axis fiber optic gyro is generally used to control a three-axis servo turntable to achieve stable scanning in inertial space, but the core problems are: 1. Signal amplification and transformation in complex noise environments...
