The application of image processing in the automatic inspection of the assembly holes of crossbeams
图像处理技术在大梁装配孔自动检测中的应用
For inspecting the assembly holes of crossbeams on an industrial spot , a method based on computer image processing is adopted , many images were collected by a ccd industrial camera , holes were inspected and recognized automatically by using proper disposing and analyzing algorithms such as image matching , threshold segmentation , feature extraction , pattern recognition and so forth
摘要采用一种基于计算机图像处理的方法，对由ccd摄像机采集到的多幅图像，结合图像拼接、阈值分割、特征提取和模式识别等算法进行处理和分析，最终实现了对大梁装配孔质量的自动识别。
