深入研究适合该图像的预处理、二值分割、边缘提取和几何形状判断方法，重点研究针尖倒装、弯曲和倒刺等不合格针尖的自动检

测方法，并基于C++ Builder平台使用C++面向对象技术实现上述图像处理过程。

-Depth for the image preprocessing, binary segmentation, edge detection and geometric methods of shape judgments, focusing on needle flip, bend and barb tips automatic detection and other methods failed, and based on C++ Builder platform using C++ object-oriented The image processing technology.
