摘要
本文对机器人电弧焊接的视觉传感及图象信息采样进行了研究，阐述了一个实用的弧焊机器人气体保护焊接视觉采样系统。
In this paper,the essentiality of the vision tracking system for robot arc welding is discussed. The image of the welding molten pool and its front joint gap is studied firstly. Thenear arc area would be imaged rather by using visible light than by using infrared ray thoughit is normally the latter that is used in this field. The crux of the method is what kind of narrowband filter should be chosen. Through experiments corresponding optical windows are determmed. For Ar arc welding it is 4064±20 A and for CO2 arc welding it is 6010±20A. Inorder to avoid the interference of arc and ensure the quality of image,a set of compound filters is designed. This approach leads to high quality of the near arc area picture which canmeet the reguirements of image processing.
