摘　　要：文章针对飞机零件的机器视觉测量方法和机构设计进行了深入研究。首先,借助Matlab软件对被测零件图像进行去噪、二值化、图像分割,以及对分割后图像的再优化;然后,采用Canny算子对边缘像素进行定位;最后,通过图像数据提取与拟合,实现密封垫圈参数的测量。实验结果表明,使用文章方法和数显千分尺对同一零件进行测量,测量平均误差仅为0.005 mm。因此,文章采用的视觉检测方法,可以实现对中小模数密封垫圈快速、高精度测量。This paper focuses on the research of machine vision measurement methods and mechanism design for aircraft parts.Firstly,the denoising,binary,image segmentation of the part to be measured and the re-optimization of the segmented image is carried out with the help of Matlab software;then,the canny operator is used to locate the edge pixels;finally,the image data ex⁃traction and fitting are carried out to realize the measurement of the sealing washer parameters.The results show that the average measurement error using the method in this paper and a micrometer on the same part is only 0.005 mm.Therefore,the visual in⁃spection method used in this paper can achieve rapid and high-precision measurements of small and medium-sized sealing wash⁃ers.
