主要围绕涡轮叶片红外热波无损检测系统硬件、软件、实验结果和图像处理等关键问题进行阐述。提出涡轮叶片内部通道异物红外热波无损检测方案,完成检测系统的设计;并完成具体实验,采集到标记区域不同温度、插入异物不同长度下的热图像。对热图像进行matlab图像处理,实现缺陷部位图像重构。 Mainly around the turbine blade infrared thermal wave non-destructive testing system hardware, software, experimental results and image processing and other key issues are described. The scheme of non-destructive testing of infrared thermal wave in the internal channel of turbine blade was put forward. The design of the testing system was completed. And the specific experiment was completed. The thermal images were collected at different temperatures in the marked area and different lengths of foreign matter. The thermal image matlab image processing to achieve defect image reconstruction.
