| 摘 要： | 根据某型固体火箭发动机钢壳体/橡胶绝热层的实际结构特点,制作了含6个脱粘缺陷的壳状实验样本,基于脉冲式红外热渡方法进行了检测研究.针对实验获取的红外热图存在"非均匀受热、表面反射、噪音大、对比度低"等问题,采用去除背景和高频强调滤波等方法对原始热图进行非均匀性校正和图像增强处理,基于数学形态学的分水岭方法实现了缺陷位置...

| Abstract: | According to the actual shell structure characteristic of Solid Rocket Motor(SRM),a specimen with shell shape including 6 debond defects was manufactured,which was detected by pulse infrared thermography.For the problem of non-uniformity,surface reflection,high noise and low contrast of the infrared images acquired by the infrared thermal camera,image correction,enhancement and segmentation algorithms were used to enhance the image quality and segment the defect from the background.Finally,the defect locati... |
