According to the calculation method of V groove's offset, width and height to acquire information and realize seam tracking.
根据V型焊缝偏中距离、焊缝宽度和焊缝高度的计算方法提取信息，实现焊缝的自动跟踪。
Therefore the offset between the center of the welding torch and the midline of the seam can be detected by the current variation. By analyzing the variation of welding current, offset information obtained in order to achieve underwater seam tracking.
通过分析焊接电流的变化规律得到偏差信息从而实现水下焊缝跟踪。
The result shows that the seam offset identified method based on PCA_RVM has better performance than traditional methods.
结果表明，基于PCARVM的焊缝偏差识别算法比传统算法有更好的识别结果和更高的运行效率。
