摘　　要：针对复合材料冲击损伤的快速检测问题,提出了使用热风作为激励源的红外成像检测方法,并实现了缺陷位置的自动识别,对于检测图像首先进行背景差分处理,然后累加背景差分后的图像以增强信噪比,最后采用阈值分割进行二值化处理,分割出冲击损伤位置。试验表明,本文方法设备操作简单、容易搭建,检测结果直观明了,可应用于航空航天复合材料损伤检测等领域。In order to estimate the impact damage of composite materials,the infrared imaging method based on hot wind heating is proposed. Firstly,the background difference is carried out for infrared images of composite materials.Then,all difference images are added to enhance SNR. At last,the threshold segmentation is adopted for binarization processing of the image,and then the position of the impact damage is segmented. The experiment results show that,this method has many advantages,for example,simple equipment,easily seen result and so on. This method can be applied for the damage detection in aerospace composite materials.
