Contour Measurement of Chemical Milling Parts Based on Binocular Vision

In order to measure the contour of the chemical milling area of aircraft skin,a measurement system based on binocular vision is constructed.Using binocular camera as vision sensor,combined with light source system and multi exposure fusion algorithm,the fused image is obtained.Based on Canny algorithm and bicubic interpolation method,the sub-pixel contour is extracted.Through ZNCC stereo matching,the 3D reconstruction of the contour of the chemical milling area is finally realized,and the contour information of the area is obtained.The experimental results show that the proposed system has high measurement accuracy,significantly improves the measurement efficiency,and its stability and accuracy meet the requirements of aircraft skin detection.
