Application Of 3D Laser Scanner In Spacecraft Assembly

Spacecraft equipment layout is complex, and there are often many differences between real product and three-dimensional design models because of flexible components and sampling parts, some spacecraft components which have high assembly precision can't be installed due to component interference or small safety distance in assembly and integration process of spacecraft. The traditional method using the ruler is not easy to measure the spatial distance of interested place, so 3D laser scanner can be used in many situations which is a key detection step in AIT Process of Spacecraft. The 2 typical applications in this paper show that these detection method extracting redundant mounting holes with large span improve the assembly efficiency. (paper)
