Rendezvous and docking method of spacecraft based on virtual reality and multimodal man-machine interface

Abstract

A rendezvous and docking method of spacecraft based on virtual reality and multimodal man-machine interface is provided. The invention discloses an aircraft rendezvous and docking method and system based on virtual reality technology and multi-modal man-machine interface, which is characterized in that: the whole cabin three-dimensional data of the docked aircraft and the target aircraft are inputto a shipboard computer to model the two aircraft three-dimensionally; the whole cabin three-dimensional data of the docked aircraft and the target aircraft are inputted to a ship-borne computer; electroencephalogram, electromyogram and hand position parameters are collected. The EEG signal, EMG signal and hand position parameter information are preprocessed. Feature extraction of EEG, EMG and hand position parameters are performed; based on the parameters extracted from the features, corresponding control commands are generated to adjust the position and attitude of the docking vehicle. Thereal-time attitude and position changes of the docking vehicle are calculated and fed back to the astronauts so that the astronauts can feel the changes of the spacecraft position and attitude. Astronauts can be better assisted to complete the manually controlled RVD mission by directly converting the intention information of the brain and limbs into the control information of the vehicle.

Description

technical field [0001] The invention relates to the field of manned spaceflight, and more specifically, relates to a method for rendezvous and docking of an aircraft based on virtual reality technology and a multi-modal man-machine interface. Background technique [0002] Space rendezvous and docking (Rendezvous and Docking, RVD) refers to the meeting of two or more aircraft at a predetermined time and position on the orbit, and after the meeting, they are structurally connected as a whole. The results of RVD often determine the success or failure of advanced space operations such as space assembly and maintenance, on-orbit assembly, recovery of products and waste, refueling and resupply supplies, interstellar lifeboats, and astronaut rotation and rescue. Therefore, with the development of aerospace technology, RVD has become an important space technology. In essence, RVD can be divided into two ways: autonomous RVD and manual RVD. Among them, the United States mainly adopt...

Problems solved by technology

However, in the state of weightlessness, astronauts will encounter the following problems: first, the ability of space-earth proprioception, space perception, space orientation, and direction recognition formed by astronauts on the ground will be significantly reduced; Judging TV camera image information, tracking screen data, hand-eye-brain coordination, and other aspects of ability have also declined, and psychological pressure has increased. Planar target images are used to complete real 3D target docking and aircraft attitude adjustment. The human-computer interaction interface has shortcomings such as non-intuitive and lack of visual stereoscopic effect.

It can be said that the existing human-computer interaction technology of hand-controlled RVD will make the astronauts bear a large workload and psychological load.
