Research on measurement method of aircraft rivet dimension based on distortion compensation

针对目前飞机铆钉尺寸测量效率和测量精度低,不能满足现代工业快速、精密测量要求的问题,本文提出了一种基于机器视觉的飞机铆钉尺寸测量方法.该方法以面阵工业CCD相机作为光学传感器,配置合适的照明条件,利用畸变补偿技术克服面阵相机的非线性失真,并通过Radon变换方法实现了飞机铆钉尺寸的精确测量.实验结果表明:该方法能够实现飞机铆钉的在线快速、高精度测量.

Aiming at the problem of low efticiency and accuracy of dimension measurement for aircraft rivet, which did not meet the requirements of modern industry quick and precise measurement,this paper put forward a kind of aircraft rivet dimension measurement way based on machine vision. This method takes theCCD-array as optical sensors, designs suitable lighting conditions, uses the distortion compensation technology and combines the Radon transform to realize accurate measurement for the aircraft rivet dimenmental results showthatthe method can realize the aircraft rivetonline fast, highprecisionmeasurement.
