摘要
研究了针对红外热波序列图像的图像分割和三维显示方法。红外热波无损检测只能得到被测工件表面温度变化的时间序列图像,无法直观到检测缺陷,利用三维显示技术可以产生深度三维立体图,方便技术人员更直观、精确地进行无损检测。三维显示效果的好坏直接取决于图像分割的效果。为此提出了基于局部极小值的区域生长分割算法,成功地提取出红外热波图像中缺陷成分的目标图像,并进行了三维显示,取得了较好的效果。
The segmentation and 3D display method of infrared thermal image were studied. Infrared thermal detecting can not be implemented well because it can only get thermal sequence images, so it is needed to produce three-dimensional images of depth using 3D display technology. 3D display has a direct effect on image segmentation results, so a new algorithm of the region growing segmentation based on the minimization. It successfully extracted the target image of the defect elements and achieved a better result i...
