摘要

焊缝位置检测一直是埋弧焊管生产中的难题，为此，在小波分析理论及其边沿检测技术的基础上，提出了一种焊缝位置检测的新方法，该方法主要涉及到焊缝图象信号的预处理，三阶梯条小波函数及其小波变换，尺度参数对变换结果的影响，检测结果的相关分析等内容，仿真结果表明，该方法检测精度高，抗干扰性能好，计算复杂度小，可靠性高，可以应用到实时控制中去。

Abstract

The detecting welding seam has been a difficulty problem in pipe manufacture for a long time

this paper proposed a new method for it based on the wavelet transform theory and its technology of edge detection. The method mainly relates to the pretreatment of the seam image

the wavelet transform based on three order spine function

the scale parameter effect on the transform results and the correlation analysis on the ultimate results. By the analysis on the theory and the simulation on computer

the method shows higher estimated precision and better capability of anti disturb. In the other hand

its complication is not high. So it can be used into real time control system.
