摘   要 ：针对裂缝红外微弱目标识别效果差，像素点灰度值具备突变性，存在背景杂波的问题，提出装配 式工程易变形结构裂缝红外微弱目标识别方法。分析装配式工程易变形结构裂缝的类别，采用反演可见光图像方法，获取装配式工程易变形结构裂缝红外微弱目标，抑制图像背景杂波的同时，采用光谱匹配方法，二次定位与确认红外微弱目标真实位置，实现装配式工程易变形结构裂缝红外微弱目标识别。试验结果表明，该方法的应用下，虚检率 、平均 FPS 、识别率皆较高，图像滤波效果较为明显，保证实际应用过程的可靠性。

Abstract: In view of the poor recognition effect of infrared weak targets in cracks, the abrupt gray value of pixel points and the existence of background clutter, an infrared weak target recognition method for cracks in prefabricated engineering deformable structures is proposed. Analyze the category of the cracks in the easily deformable structure of the assembly engineering, use the inversion visible light image method to obtain the infrared weak target of the cracks in the easily deformable structure of the assembly engineering, suppress the background clutter of the image, and use the spectral matching method to locate and confirm the true position of the infrared weak target twice, so as to realize the infrared weak target recognition of the cracks in the easily deformable structure of the assembly engineering. The experimental results show that under the application of this method, the false detection rate, average FPS and recognition rate are higher, and the image filtering effect is obvious, which ensures the reliability of the actual application process.

Keywords: Easy-deformable structural cracks in prefabricated engineering; weak infrared target; identification method; image preprocessing;
