Research on the Application of Drainage Pipeline Diameter Measurement System Based on Projection Transformation and Space Circle Fitting
In complex environments,it is difficult to obtain the diameter of underground drainage pipelines,and traditional methods have low accuracy.Therefore,a new pipe diameter measurement system is designed,which fully utilizes the characteristics of underground pipelines and adopts a unique structural design.The system effectively compensates for the distortion error of pipe diameter measurement using projec-tion transformation theory,and combines the least squares space circle fitting algorithm based on RANSAC algorithm to filter and fit the meas-urement data,obtain accurate pipe diameter values and evaluate the reliability of the fitting results.The application in actual pipeline measure-ment shows that the diameter measurement system has the advantages of strong practicality,high efficiency,and high accuracy in underground drainage pipeline diameter measurement.
