摘要：地面远距离运动目标检测是红外成像防御中的关键技术之一。地面远距离运动目标检测指利用红外探测器对远距离运动目标实现自动探测和捕获。由于目标距离较远，在红外探测器上成像面积较小，同时远距离运动目标容易被遮挡，很难将目标从复杂的地面背景中提取出来。提出了一种能够在面阵红外探测器转动的条件下实现远距离地面运动目标检测方法。首先利用图像信息计算红外探测器的运动补偿参数并通过背景更新获取目标一次检测结果，然后采用光流法获取背景和目标的运动信息，通过计算背景和目标之间的运动信息相关性实现目标最终检测。实验采用多种场景对文中算法进行验证，结果表明该方法通过转动红外探测器可以扩大目标搜索区域，利用背景和目标之间运动信息的相关性有效地克服了目标遮挡、目标重叠和视差等问题。

Abstract:The ground remote motion target detection is one of key techniques in infrared imaging defense.The ground remote motion target detection is a method which can automatic detection and capture the remote motion target by Infrared detector.It is difficult to extract the target from the complex background,because the target is distance,imaged area is small on infrared detector and easily blocked.

A method can realize detect the ground remote motion target by rolling the area array infrared detector

was presented.First,the motion compensation parameters were calculated through the image information and target first detection result was obtained through background update,then background and target motion information were obtained through the optical flow and target final detection result was obtained through calculating the relationship between background and target motion information.Experiments validate the proposed algorithm using a variety of scenarios;the results show that this method can expand the target search area by the rotating infrared https://www.360docs.net/doc/757340498.html,ing the relevance of the movement information
