A Missile Level Measuring Method Based on 3D Coordinate Transformation Principle

Abstract

The invention belongs to the field of technologies for horizontally measuring missiles, and particularly relates to a method for horizontally measuring missiles on the basis of a three-dimensional coordinate transformation principle. The method has the advantages that a digital measuring technology and the three-dimensional coordinate transformation principle are combined with each other and are integrally applied to horizontally measuring the missiles, so that the missiles can be precisely, efficiently, digitally and horizontally measured, spatial three-dimensional coordinates of various measuring points of the full-size missiles in the same coordinate system can be acquired, technological parts of the missiles can be segmentally measured under the condition that components where measuring bases are located cannot be horizontally measured in final assembly procedures, coordinate positions of the measuring points can be ultimately evaluated and comparatively analyzed under the condition of the same bases by the aid of a process for transforming and computing the coordinates, accordingly, horizontal and symmetrical planes of missile bodies can be established according to the horizontal measuring points, and deformation of the various measuring points and deformation degrees of positions such as the missile bodies and missile wings can be acquired.

Description

technical field [0001] The invention belongs to the technical field of missile level measurement, in particular to a missile level measurement method based on the principle of three-dimensional coordinate conversion. Background technique [0002] Horizontal measurement is the process of checking and adjusting the relative position accuracy of missile parts (groups) during missile assembly and maintenance. It is the final detection of relative position and main geometric dimensions or parameter errors of missile parts (groups). [0003] Missile level measurement is generally required by the designer to mark the measurement points during component design. The measurement points are processed during the component manufacturing process. After the docking and assembly of the missile components are completed, the assembler will level the missile body according to several reference points determined by the design. , by measuring the positions of other measurement points relative to...

Problems solved by technology

This measurement method needs to place the product under test on the front and rear support snap rings in the center of the measurement platform, and be located in the measurement area of ​​the measurement platform. For large-scale products, such as about 10m and multi-cabin docking products, it is necessary to use about 10m The platform is used to measure the full-scale state missile, the platform construction cost is high, the measurement accuracy is low, and the measurement efficiency and safety are difficult to guarantee.
