Extraction of Weld Pool Feature Based on Visual Sensing during High-power Fiber Laser Welding

摘要：

　　In the process of the high-power fiber laser welding,the weld pool feature is related to welding quality.Here,a near infrared image acquisition system was used to acquire the weld pool information.After acquiring the weld pool regional image,the methods such as filtering image denoising,image enhancement,morphological processing and image segmentation were applied to analyze the weld pool feature information.It offered a reliable visual information method for monitoring of welding quality.
