Marine target infrared detection method and device

The invention relates to a marine target infrared detection method and device and relates to the field of infrared detection technologies. The marine target detection method comprises the steps that amarine target and infrared radiation luminance of a corresponding background of the marine target are acquired; and an infrared contrast ratio of the marine target to the corresponding background ofthe marine target is obtained according to the marine target and the infrared radiation luminance of the corresponding background of the marine target. According to the marine target infrared detection method and device, by obtaining infrared radiation characteristic information of the marine target and the corresponding background thereof, infrared characteristics of the marine target are recognized quickly and accurately. 本申请涉及一种海上目标红外检测方法及装置，涉及红外检测技术领域，所述海上目标检测方法包括获取海上目标及所述海上目标的对应背景的红外辐射亮度；根据所述海上目标及所述海上目标的对应背景的红外辐射亮度获得所述海上目标与所述海上目标的对应背景的红外对比度。本申请通过获得海上目标红和其对应背景的红外辐射特征信息，快速准确识别海上目标的红外特征。
