摘要
在讨论了常用的各种光刀中心提取法的基础上 ,提出了一种光刀中心自适应阈值提取法。该方法结合了极值法、阈值法和重心法 ,避开了它们各自的缺点 ,消除了噪声干扰 ,从而实现了光刀中心的精确定位。该方法具有稳定性好、精度高、速度快等特点。
The paper discusses several common methods used to acquire the light-knife center, and analyzes their defects. A new adaptive threshold method is proposed, which combines the extremum method with the threshold method and the barycenter method. The new method eliminates the disadvantages of the previous methods such as the noise and realizes the precise orientation. The method is characterized by good stability, high precision and high speed, etc.
