In this paper, gear parameters are measured with the machine vision technology, firstly, gear edge is extracted from the gear image using image processing method, secondly, the gear center is set in gear edge image with random Hough transform, four basic gear geometry parameters are identified by their measurement algorithm. And compare with the measured values by the traditional measurement method,...
Through the practice of profile modeling milling machine by digital transformation, the author analyzes characteristic parameters which influences sample-mold precision of measurement. It not only employs discrete B-spline surface approximation of mathematical model for profile modeling measurements, making measurement of the geometric surface parameters orderly and digital, but also achieves a pattern-lump...
Construction of intelligent transportation system is a necessary requirement for the development of transport, and LPR(License Plate Recognition) is an important part of construction of intelligent transportation system, Therefore, the research of license plate recognition method is of importance. The license plate character is recognized by building BP artificial neural network in this paper, it...
The paper discusses the OPC technology and it brings functions and benefits in monitoring system of the small AS/RS. As an example of the monitoring system of an airport catering company, the paper analyzes the way of data access in this monitoring system according to the typical data access method of OPC. The monitoring system adopts Siemens S7-300 PLC Ethernet communication module and OPC communication...
