Abstract

The invention discloses an ultra large geometric parameter measuring system self-calibration method based on the guidance of a wireless sensor network. The method comprises the following calibration steps that: a beacon node electromagnetic wave receiving and transmitting point of a beacon node in a measuring base station is subjected to rough self-calibration; and the calibration result of the rough self-calibration is used for guiding a laser absolute distance measuring system to perform precise self-calibration on an absolute zero datum and the beacon node electromagnetic wave receiving and transmitting point. The method has the advantages that: hardware is simple, calibration can be performed in a measuring process, and the calibration results of all measuring base stations have the same precision.

Description

technical field [0001] The invention relates to a measurement system of super large geometric parameters, in particular to a self-calibration method of the super large geometric parameter measurement system guided by a wireless sensor network. Background technique [0002] With the continuous development of the manufacturing industry, the size of the product has reached tens or even hundreds of meters. This means that the measurement range is also expanded, and realistic requirements are also put forward for the measurement of ultra-large geometric parameters. The measurement of super large geometric parameters can be achieved indirectly by measuring the spatial coordinates of some target points, that is, locating the marker points. In recent years, ultra-large-scale geometric parameter measurement technology has been widely used in industrial manufacturing, such as large aircraft and ship manufacturing. [0003] The ultra-large geometric parameter measurement system guide...
