基于图像传感器的焊缝偏差信息提取方法

A method of the welding seam declination abstraction based on the image sensor

介绍了焊接图像传感器的传感原理及其利用CCD摄像机获得的焊接温度场图像,叙述了小波变换方法用于边缘检测的原理,论述了利用三次样条小波函数对温度场图像进行变换得到焊缝位置和焊炬位置的算法,最后给出小波变换对图像的处理结果以及焊缝偏差量。

The principle of the image sensor and the welding temperature field image got from CCD sensor are introduced.Then the principle of the image edge detection based on wavelet transform method is narrated and the algorithm is discussed that how to use the cubic spline wavelet function to transform the image of temperature field and recognize the position of welding seam and welding torch, eventually the declination of welding seam and the processing results of the image based on wavelet transformation are provided.
