Study And Development Of Data-Processing And 3D Visualization In Industrial Measring System

AS a new applying field in measuring technology, industrial measuring system is more and more being paid attention to by professional. It can survey fleetly the static or dynamic object by means of combining high precision survey and data processing , and determine exactly the figure, dimension, distance , space place and dynamic state of object .This paper research data processing and data visualization aiming at building block industrial measuring system which developed by us own.This paper firstly introduce the directional theory and directional method of building block industrial measuring system, and analyze the factors which impact surveying precision in the course of surveying. Then it expatiates and compares the conversion methods about part surveying coordinate system, surveying coordinate system and work piece coordinate system. It utilizes ADO Data control to realize the storage and display of real time data. Bring forward least-square method to fit the data of rule surface by means of the MathKemel of Mathematica software. It expatiate the method of expressing complex surface by insert arithmetic. Also brings forward a method to display the guideline of precision after data processing by means of MSChart control .Carries out 3D visualization of surveying model using OpenGL. Last this paper introduces the idea of designing and major function of module of data processing and module of 3D figure vision and applying to practice.
