【摘要】 针对工作原理未知的复杂电路板故障诊断的问题,提出了一种基于红外图像处理技术的通用电路板故障诊断算法。通过引入"广义距离"的概念对电路板不同工作状态下红外图像进行对比,快速定位印刷电路板的故障区域。算法运算简单,实时性好,通用性强。实验结果表明该算法的有效性。更多还原

【Abstract】 For the fault diagnosis problem of complex printed circuit board whose working principle is unknown, a general fault diagnosis algorithm based on infrared image processing is presented.By introducing the concept "generalized distance" to compare infrared images in different working conditions and locate the fault area on the printed circuit board rapidly.The algorithm is simple,real-time and generalized.The result of the experiment shows the validity of this algorithm.更多还原
