Embodiment Construction

[0037] The measurement process of the present invention will be described in detail below in conjunction with the accompanying drawings. These descriptions are only illustrative and are not intended to limit the protection scope of the present invention.

[0038] figure 1 Schematic diagram of the layout of the precise measurement method for the assembly of the satellite antenna deployment system. A four-digital camera dynamic photogrammetry system is set up. The table 3 rotates, slides up and down on the camera bracket 2 through the slide rail 4, and moves 1 through the AGV trolley.

[0039] Four digital cameras 5 are respectively placed next to the two long sides of the satellite antenna deployment system to be tested, two are placed on each side, so that the field of view of the four digital cameras 5 covers the satellite antenna deployment system, and every two digital cameras 5 There are overlapping fields of view. Wherein the satellite antenna deployment system includes...

Abstract

The invention relates to an assembling precision measurement method and device of a satellite antenna unfolding system. A four-camera photogrammetric system measures point-like coding signs in a panel, a hinge and a rod system of the satellite antenna unfolding system, digital images with the point-like coding signs of the panel, hinge and rod system in different positions are obtained, the flatness of the panel and the axis positions of the hinge and the rod system are calculated via computer image processing and least square fitting, and the assembling precision of the satellite antenna unfolding system is determined. Thus, the positions of the linkage and the rod system of the satellite antenna unfolding system can be measured automatically and rapidly in high precision, the flatness ofthe panel within the range of 10m*2.5m is <=0.1mm, the axis measuring precision of the hinge within the range of 2.5m*0.5m is <=0.1mm, the measuring precision of the rod system whose length is lowerthan 1m is <=0.1mm, and the measuring precision of the rod system whose length is greater than 4m is <=0.3mm.

Description

technical field [0001] The invention belongs to the technical field of industrial measurement, and in particular relates to a precision measurement method and device for assembling a satellite antenna deployment system. Background technique [0002] Large-scale satellite antenna is an important part of a satellite and an important physical platform that directly performs satellite functions. It is a new type of space structure that has emerged with the rapid development of aerospace science and technology in recent years. It is widely used in communications, measurement and control, deep space exploration, and Many fields such as earth observation and military reconnaissance. [0003] The satellite antenna deployment system is a key component of the satellite. The antenna deployment system consists of a set of complex deployable space truss mechanisms. The size coupling of each antenna rod system is high, and the interface matching degree between the antenna rod system and t...
