Abstract

A multifunctional measurement standard device relates to the technical field of optical precision mechanical measurement, solves the problems of tedious process, inconvenient operation, low precision and the like in the prior art, and comprises a standard base, a reflecting mirror surface, a cube-corner prism, a photogrammetry coding identifier and a photogrammetry point, the reference base comprises a mounting surface, a first surface, a second surface and a third surface, and the first surface, the second surface and the third surface are perpendicular to one another; the number of the reflecting mirror surfaces is at least two, the two reflecting mirror surfaces are perpendicular to each other, and the mutually perpendicular reflecting mirror surfaces are used for autocollimation of the theodolite; the cube-corner prism, the reflecting mirror surface, the photogrammetry coding identifier and the photogrammetry point are all arranged on the surface, except the mounting surface, of the reference base, the photogrammetry coding identifier is also arranged on the surface, provided with the photogrammetry point, of the reference base, and the photogrammetry coding identifier is used for identifying the surface where the photogrammetry point is located. The method is high in stability measurement accuracy, convenient in precise installation and adjustment, and simple and convenient in measurement and establishment of a measurement coordinate system.

Description

technical field [0001] The invention relates to the technical field of optical precision mechanical measurement, in particular to a multifunctional measuring reference device. Background technique [0002] As the requirements for imaging resolution continue to increase, the aperture of space cameras is getting larger and larger. However, limited by the space carrying capacity, aerospace high-precision optical systems have to use more lightweight materials to make truss structures. The stability of the large-scale truss structure is an important prerequisite to ensure that high-precision optical-mechanical systems such as space cameras meet the index requirements. Therefore, precise measurements of the stability of large-scale trusses at ground level are required. [0003] At present, spatial coordinate measurement is generally used for the stability measurement of truss structures, including theodolite measurement, laser tracker measurement, photogrammetry, etc. In order ...
