Embodiment Construction

[0014] Such as figure 1 As shown, the aircraft level measurement method based on the working space measurement and positioning system includes the following steps:

[0015] (1) Determine the measurement workspace according to the external dimensions of the measured aircraft and the positions of the measurement points, and determine the number of laser scanning base stations to be 9, so that each measurement point is located at the optimal working distance of 6m from the laser emission base station, and two The intersection angle of the laser emitted by the laser transmitting base station is 90°, and the measurement point is guaranteed to be unobstructed, which has good measurability;

[0016] (2) Use the reference ruler to calibrate the external parameters of the measurement workspace formed by all laser scanning base stations, and establish the coordinate system of the workspace measurement and positioning system;

[0017] (3) Select three reference points on the aircraft fu...

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...
