| 摘 要： | 焊缝跟踪是实现焊接自动化的前提条件.间隙的变化会影响基于熔化极气体保护焊（metal active gas,MAG）的管道自动打底焊的焊接质量,为此设计了基于电荷耦合器件（charge-coupled device,CCD）视觉传感的MAG打底焊焊接过程监控系统.但从CCD获取的焊接过程的图像通常具有很大噪声,亟需设计...

| Abstract: | Seam tracking is a prerequisite of implementing automatic welding process.Gap variance has an important impact on the welding quality of MAG for pipe-line backing welding.A welding process monitoring system based on CCD is designed.However,the images obtained from CCD with MAG welding often have much noise.Therefore,accurate and high efficient image processing methods for extracting seam location are urgently needed.A new seam location extracting method is presented,the molten welding pool area is obtained ... |
