Augmented Reality Based Guidance System for Spacecraft Propulsion System Final Assembly

Abstract

The invention discloses a spacecraft propulsion system general assembly guidance system based on augmented reality, which comprises a guidance information generation module, a structural cabin plate positioning module, a guidance information visualization module and a guidance state control module. The guidance information generation module is used for reading relevant information to form a propulsion system general assembly process information set. The structural cabin plate positioning module is used for calculating the position and attitude parameters of a satellite structure cabin plate relative to an operator in the working scene and providing the position and attitude parameters to the guidance information visualization module. The guidance information visualization module is used for superimposing and displaying the virtual process guidance information on the spacecraft structure entity. The guidance state control module records the progress of the general assembly implementation so that a user can continue to operate under guidance from the interrupt step after the guidance is interrupted. According to the invention, the assembly efficiency of the propulsion system under the complex spacecraft assembly scene is improved, the probability of erroneous installation of components of the spacecraft propulsion system is reduced, and the predefined process of guiding process information is simplified.
