Paper Abstract

Considering the diameter of steel-pipe is from 910mm to 1500mm, the weight is from 1000Kg to 10000Kg, the length is above 6 m and the request of factory, this paper presented the length and weight measuring system for steel-pipe in fieldwork. The relative measuring method with double CCD (Charge Coupled Device) cameras, capturing and processing the images and acquiring the length of steel-pipe with industrial control computer is put foreword. With emphasis on the system structure, measuring principle, demarcating technology and method how to improve the system reliability are investigated. Comprising simple hardware this system is easy to build and demarcate, and the info-benchmark determining and specially the image recognition are depended on software technology, which choosing homologous equivalent image cell weight to convert the length and get higher measuring precision by studying the character of the shape and placement of the pipe termination point image. Via locale run, this system was proved to be firm and the measuring error is less than 10/00.
