现有基于机器视觉的智能检测技术是实现其生产质量快速、自动检测与控制的新型重要手段。在此基础上，本文介绍了基于HALCON机器视觉软件的检测系统和针对化妆品瓶底批号的图像处理关键技术，包括灰度值调整、形态学运算、字符分割及识别数字对象-Existing machine vision based intelligent detection technology is to achieve its production quality fast, automatic detection and con

主要编写的图像预处理步骤的代码，包括灰度化，二值化，高斯模糊，图像增强(The main preparation of the image preprocessing steps of the code, including grayscale, binary, Gaussian blur, image enhancement.)

将一副灰度图像进行傅里叶变换，产生变换后的图像(Fourier transform of a gray image is used to generate transformed images.)
