Autonomous Tracking Measurement Technology for Aircraft Skin Seam Based on Structured Light
Aiming at the automation measurement problem of aircraft skin seam gaps and step differences,a skin seam autonomous tracking method is studied based on line structured light visual detection technology.By combining traditional image morphology based processing methods with optical flow methods,real-time tracking of skin seam features is achieved,thereby determining the measurement positions of gaps and step differences.The accuracy of seam tracking was improved by correcting the eye-in-hand calibration parameters based on measured data.The experimental results show that when the tracking speed is 7 mm/s,the position accuracy of seam tracking is higher than 0.500 mm,and the attitude accuracy of seam tracking is higher than 0.5°.This tracking system has good accuracy and stability and can meet the requirements of aircraft skin seam tracking.
