| 摘 要： | 熟练焊工能够通过观察熔池表面的凸凹信息获取熔池的成形,在机器人智能化焊接过程中,采用视觉传感方式模拟焊工视觉获取熔池的形状信息。图像的灰度值决定于光源特性、物体表面形状、反射特性和摄像机特性。熔池图像隐含熔池的形状信息,为了从图像中提取熔池的形状信息,分析了铝合金脉冲GTAW焊的熔池表面反射特性,熔池表面由漫反射表面、镜面反射表面和互反射表面组成,建立了熔池表面反射模型。

| Abstract: | The skilled welder can acquire the shape information of welding pool by welding pool surface.The visual sensing can be used to simulate the skilled welder to acquire the information of welding pool.The shade of gray in image depends on illumination,shape,reflection and CCD camera.The image of welding pool embodies the information of shape.In order to acquire shape information from image,the reflection characteristics of aluminum alloy pulse GTAW welding pool are analyzed and the reflectance model of welding pool is built. |
