Applied Research on Digitalized Identification Procedure of Ground Vehicle Profile in Infrared Image

面向车辆装备的红外线隐身特性评价问题,进行了红外线图像中地面车辆目标轮廓的数字化识别方法应用研究.首先,在对红外线图像的人工观察基础上,辅以图像放大处理,对地面车辆装备几何轮廓在红外线图像中的清晰程度进行判定;然后,综合运用、比较边缘检测算子、图像增强和图像分割等数字图像处理技术,研究确定了针对不同清晰程度的红外线图像处理、车辆轮廓提取的有效方法集,形成了一种进行红外线图像中地面车辆轮廓的数字化识别分析流程.

An applied research on the digitalized identification procedure of a ground vehicle profile in infrared image is carried out in order to evaluate its infrared stealth characteristics for the vehicle equipment. Through enlarging and observing the infrared image of the equipment, a clearity classification of its profile is defined in the infrared image. A series of digital image processing methods, such as the edge detection algorithm, the image enhancement and the image segmentation, are used comprehensively for several existing infrared photos. A set of effective methods for extracting the vehicle profile image is suggested on the different definition levels. A procedure of the digital identification and analysis is presented for the ground vehicle profile in infrared image.
