Abstract

The invention relates to a method for horizontal measurement of a guided missile with a laser tracker. The guided missile is put on a fixed position and located under a virtual coordinate system of the laser tracker, coordinates of all points under the virtual coordinate system are calculated by positioning a target ball on all the horizontal measurement points of the guided missile, the horizontal measurement points on a missile body are used for fitting a virtual reference plane, the height difference, relative to the virtual reference plane, of every two points on a pneumatic face is calculated, and then an installation error is determined. High-precision positioning equipment is adopted for horizontal measurement, and high precision of the advanced equipment can be sufficiently utilized for improving the precision and efficiency of horizontal measurement of the guided missile. Meanwhile, traditional horizontal measurement equipment is reduced, and cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to the application of a laser tracker in missile level measurement. Background technique [0002] There are special technical requirements for the relative positions of the components on the missile. Their accuracy relative to the theoretical installation position will directly affect the control performance and flight performance of the missile. It can be seen that level measurement is a very important process to ensure the accuracy of missile installation. [0003] The three-level maintenance of the missile involves the disassembly and assembly of the missile. If the cabin and aerodynamic surface are disassembled during the product maintenance process, after the missile is reassembled, horizontal measurement should be carried out to determine whether the installation accuracy of its cabin and aerodynamic surface still meets the technical specification requirement...
