Metal manufacturing defect repairing method and system

The invention provides a metal manufacturing defect repairing method and system, and relates to the field of image processing and manufacturing. The metal manufacturing defect repairing method comprises the following steps: acquiring an infrared thermogram sequence of a specified frame number; performing compression and reconstruction on the heat map sequence through a heat map sequence compression and reconstruction technology; carrying out image processing to obtain a contrast-enhanced image; after image processing is carried out on the heat image, judging whether hot spot heat exists in the heat image or not, determining the area where the defect is located according to the judgment result, and performing defect repairing on the defect position. The defect information of the product can be quickly evaluated, the defect position is re-melted and subjected to repair welding, and the product rejection rate is reduced. 本发明提出了一种金属制造缺陷修复方法及系统，涉及图像处理及制造领域。一种金属制造缺陷修复方法包括：获取指定帧数的红外热图序列；通过热图序列压缩重建技术对热图序列进行压缩重建；进行图像处
