Large large field of view global measurement method using coordinates tracking control board

Abstract

This invention provides a large field of view global measurement method using a coordinates tracking control board, belonging to the visual measurement field. The method employs a coordinates tracking control board installed on an adapter bracket, effectively integrates a visual measuring device and a laser tracker under the condition of not sharing a same field of view, and separates and calibrates internal and external parameters of left and right cameras to build an overall coordination system of a measurement scene so as to complete overall measurement based on a large field of view. The method can realize rapid and highly accurate measurement of large parts under a complex operating condition in a large field of view scope, is a measurement mode combining a plurality of types of optical components. The measurement method has the characteristics of large field of view and high efficiency, and can conveniently measure covered parts of target components, and rapidly complete large field of view global measurement in the industrial field.

Description

technical field [0001] The invention belongs to the field of visual measurement, and relates to a large field of view global measurement method using a coordinate tracking control board. A measurement method for optical components. Background technique [0002] With the continuous growth of the country's comprehensive strength, the application of large aircraft is becoming more and more extensive. The large parts used in the aircraft manufacturing process put forward high requirements for its manufacturing, molding and assembly testing. At this stage, there are mainly the following methods at home and abroad for the measurement of large parts in the aviation field: machine vision method, laser tracker measurement method, indoor GPS measurement method, laser radar measurement method and three-coordinate measurement method. The traditional machine vision method is to obtain the image information of the measured object through machine vision products, and complete the measurem...
