Measurement reference device capable of being used for establishing a coordinate system

Abstract

The invention discloses a measurement reference device capable of being used for establishing a coordinate system, belongs to the technical field of optical and precision machinery adjustment, and solves the problems of low efficiency, inconvenience in operation, insufficient precision and the like in establishing a cubic prism measurement coordinate system. The reference device comprises a modulebase, a cubic prism mounting base, a cubic prism, a pyramid prism mounting base and a pyramid prism, the cubic prism is mounted on the module base through the cubic prism mounting base; the pyramidprism is installed on the module base through the pyramid prism mounting base, the cubic prism and the pyramid prism are arranged at the two ends of the module base, the relative pose relation betweenthe cubic prism and the pyramid prism is kept constant, and the normal of the surface, except the installation surface, of the cubic prism is not shielded; a theodolite and a laser tracker are used for aiming at the reference device, fitting and calculation are not needed, the coordinate axis orientation and the coordinate origin position can be directly obtained at the same time, then a coordinate system is established, and the installation and adjustment precision and efficiency are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of optics and precision machinery adjustment, and in particular relates to a measuring reference device which can be used to establish a coordinate system. Background technique [0002] For precision systems in the fields of aerospace, remote sensing, and astronomy, in addition to processing and manufacturing high-precision optical and mechanical components, it is also necessary to use effective methods to adjust each optical and mechanical components to their respective theoretical positions, so that the overall system Meet the expected design indicators. The accuracy and efficiency of the adjustment method directly determine the target realization and development cycle of the entire system. [0003] During the assembly and adjustment process of high-precision optomechanical systems, it is usually necessary to measure the spatial pose relationship between the reference coordinate systems of each component,...
