Design of Automatic Positioning System Based on Multi-Sensor for Big Crane-Form Pipeline

摘要

Automatic positioning system for big crane-form pipeline is mainly to achieve the precise positioning of circular opening and big crane-form, pipeline, and it's also the auxiliary system of achieving automatic loading. In order to speed up the positioning and improve its precision, the system is designed to use a combined method of infrared and machine vision; infra-red is used to quickly positioning, while template matching and circle center detection are used to precise positioning. The system transmits the data of position of circular opening to PLC through serial port. And then, the big crane-form pipeline is controlled to backward, forward, lower and transport oil by PLC. The positioning of the system is precise and express.
