随着传感器性能的不断提高和计算机图像处理技术的不断发展,现代焊接的自动实时控制技术达到了一个更高的水平,利用视觉传感技术获取实时焊缝图像,并利用图像处理技术对焊缝位置进行实时跟踪已经成为现代化焊接设备不可缺少的关键技术。视觉传感技术具有非接触、反映速度快、抗干扰能力强等特点,使其在焊接图像的应用中得到广泛关注。本文首先以CCD摄像机为例介绍了视觉传感器的工作原理以及通过传感器进行焊接图像信息的收集过程,最后重点地针对基于视觉传感的焊缝图像采集过程中可能遇到的干扰问题和焊缝图像特点进行了具体的分析和总结。
With the continuous improvement of sensor performance and the continuous development of computer image processing technology, the automatic real-time control technology of modern welding has reached a higher level. The visual sensing technology is used to obtain the real-time weld image and the image processing technology is used to weld Real-time tracking of location has become an indispensable key technology in modern welding equipment. Visual sensing technology with non-contact, reflecting the speed, anti-interference ability and other characteristics, to make it widely used in the welding image applications. In this paper, the working principle of the visual sensor and the process of collecting the welding image information are introduced by taking the CCD camera as an example. At last, the interference problems that may occur in the process of image acquisition based on visual sensing and the image of the weld Characteristics of a specific analysis and summary.
