Full-airplane horizontal measurement method based on work space measurement location system

Abstract

The invention provides a full-airplane horizontal measurement method based on a work space measurement location system. The method comprises first determining the number of measured work spaces and laser scanning base stations according to appearance dimensions and positions of measuring points; then using a standard ruler to calibrate external parameters of the measured work spaces formed by all the laser scanning base stations, and building a work space measurement location system coordinate system; then unifying the work space measurement location system coordinate system and an airplane coordinate system; using vector rods of the work space measurement location system to respectively perform contact measurement on each measuring point; and finally enabling measured coordinate values of each measuring point to be led into a data processor of the work space measurement location system, and comparing the actually-measured coordinate values with a theoretical value so as to judge whether airplane deformation is within an allowed range. The full-airplane horizontal measurement method solves the problems that a traditional airplane horizontal measurement method is poor in measurement precision, large in workload and low in measurement efficiency and is subjected to influences of operator's proficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of large-scale three-dimensional coordinate measurement on the aircraft industry site, and in particular relates to a high-precision aircraft digital full-aircraft level measurement method based on a workspace measurement and positioning system. Background technique [0002] Workspace Measurement Positioning System (wMPS: Workspace Measurement Positioning System) is a large-scale networked measurement system developed to meet the needs of global measurement and control on the industrial site. Its advantage is that it can realize the networking of large-scale spatial coordinates High-precision automatic measurement. The system forms a measurement network through multiple rotating laser emitting devices (transmitting stations), and uses the automatic measurement method of spatial angle intersection based on photoelectric scanning to locate a single receiver. The transmitting station emits an optical signal wit...
