Research on Satellite Cable Laying and Assembly Guidance Technology Based on Augmented Reality

Spacecraft satellite has the characteristics of large number of cables, many branches and complex layout. The traditional cable-laying task adopts the combination of viewing the two-dimensional electronic assembly process and browsing 3D model, which shows some problems, such as poor understanding, inaccurate assembly accuracy, low efficiency and insufficient assembly-guidance. For this purpose, the application of augmented reality (AR) in the Aerospace Satellite cable-laying assembly was studied, using the SLAM positioning and tracking technology and ORB algorithm to solve the problem of multiple artificial markers and limited field of vision in the satellite cable-laying; The virtual real occlusion processing method based on contour tracking was used to solve the real occlusion relationship between virtual cable and satellite structure; Based on the deployment of Hololens, the AR visual cable laying guidance system was constructed. Through the immersive 3D display and visual process information, the cable-laying assembly-guidance can be realized. Finally, it is applied to a certain type of satellite for application verification, the results show that augmented reality technology has a higher advantage than the traditional way in satellite cable-laying, and can effectively improve the efficiency and assembly quality in the satellite cable-laying assembly.
