A Measuring Benchmark Applicable to Establishing a Coordinate System

Abstract

A measuring reference device that can be used to establish a coordinate system belongs to the technical field of optical and precision mechanical adjustment, and solves the problems of low efficiency, inconvenient operation, and insufficient precision in establishing a cubic prism measuring coordinate system. The benchmark includes: a module base, a cube prism mounting base, a cube prism, a corner cube mounting base and a corner cube; the cube prism is installed on the module base through the cube prism mounting base, and the corner cube is mounted on the On the module base, the cube prism and the corner cube prism are arranged at the two ends of the module base, so that the relative pose relationship between the cube prism and the corner cube prism is kept constant, and the normal line of the surface of the cube prism except the mounting surface is not blocked; the present invention Using the theodolite and laser tracker to aim at the standard, without fitting and calculation, the orientation of the coordinate axis and the position of the origin of the coordinate can be obtained directly at the same time, and then the coordinate system can be established, which greatly improves the accuracy and efficiency of assembly and adjustment.

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,...
