Rapid detection method of abnormal roundness area of large diameter steel cylinder
Large diameter steel cylinders may have one or more roundness anomalies for some reason,during fabrication,transport,installation and operation,which don't not meet the relevant requirements for equipment acceptance and operation.At present,the detection methods for large diameter cylinders are complex and not suitable for rapid detection.In this paper,based on the principle of coordinate measurement,combined with the non-contact automatic measurement mode of high-precision total station,an automatic search procedure is prepared by Matlab program,and a rapid detection method of large diameter steel cylinder roundness anomaly area is proposed.The simulation by AutoCAD and the results of field measurements show that the inspection method is not only fast,but also can significantly improve the detection accuracy by increasing the density of measurement points,providing accurate data for subsequent repair and improvement work.
