质量控制、成本降低以及最重要的人类和环境安全是刺激自动检测等技术投资的重要原因。由于储罐目前用于储存有害产品，因此储罐中焊接线的自动检测具有特殊意义。为了进行可靠的检测，必须精确地检测熔接线位置。本文提出了一种储罐焊缝检测系统的开发。实现了基于视觉信息的系统并进行了测试。该系统采用了基于α-β滤波器的容错估计过程和本文提出的基于模型的故障检测方法。
Quality control, cost reduction and above all, human and environmental safety are great reasons that stimulate the investments in technologies such as automatic inspection. The automatic inspection of weld lines in storage tanks is of special interest due to the fact that such tanks are currently used to store harmful products. For a reliable inspection it is necessary to accurately detect the weld line position. In this paper the development of a system to perform weld line detection in storage tanks is proposed. The system based on visual information is implemented and tested. Such system makes use of a fault-tolerant estimation process based on the α-β filter and a model-based fault detection method, proposed in this paper.
