Spacecraft cable network three-dimensional forming system and method based on augmented reality

Abstract

The invention relates to a spacecraft cable network three-dimensional forming system and method based on augmented reality, and belongs to the technical field of digital manufacturing. Aiming at the problems of long preparation period of a non-wood template, inaccurate confirmation of cable network offline and binding points, repeated confirmation of design and process requirements required by field operation and the like, AR glasses are used for superposing a three-dimensional design model containing a satellite structure onto a laying framework tool structure to form a three-dimensional forming operation environment of a cable network entity. According to a key laying feature extraction result in the three-dimensional design model, cable entity rapid wiring and identification are guided,and the accuracy of cable three-dimensional forming is enhanced on a laying framework tool; pushing the key laying features to a real object operation table top in an augmented reality'video stream 'mode by utilizing the display advantages of the augmented reality technology; and through gesture interaction, an operation completion state is quickly fed back, so that the usability of the user is improved.

Description

technical field [0001] The invention relates to a three-dimensional forming system and method for a spacecraft cable net based on augmented reality, and belongs to the technical field of digital manufacturing. Background technique [0002] The cable network is one of the important components of the spacecraft, and it is the link and bridge of each subsystem and cabin. Traditional cable network production mainly uses wooden molds + branch length diagrams for cable assembly and laying, but the wooden mold manufacturing cycle is long, takes up a large operating space, the layout of on-board equipment changes frequently, and the versatility of cross-model platforms is insufficient, so the branch length diagrams cannot be well reflected For space occupation of on-board equipment, key binding points, whole-star assembly, physical cable forming and other requirements, electrical installation workers still need to repeatedly check the contact table, technical requirements, process d...
