摘要
舰载光电跟踪系统在导弹武器进行目标打击、预警与拦截中起到至关重要的作用。舰载光电跟踪目标时,目标距离由激光测距仪测量。一旦激光测距仪发生故障,则无法获取打击目标的距离信息,目标的具体坐标也无法确定。针对该问题,利用舰载电视和红外跟踪仪,建立异源双目立体测距系统进行测距,根据视差定位原理,将红外与可见光图像进行配准,获取距离信息。最后对影响测距的因素进行了分析,在设定的条件下进行仿真,理论上可以获取导弹拦截目标的距离,实现目标的定位与跟踪。
Shipborne photoelectric tracking system plays an important role in missile attack,early warning and interception.The shipborne optical-electronic tracking system is a commonly used tracking device on the ship,in which the laser range finder measures the distance information of the target.When the laser range finder fails,the distance information of the target cannot be ob⁃tained,that is,the specific coordinates of the target cannot be determined.Aiming at this problem,a binocular stereo ranging sys⁃tem is established by using shipboard TV tracker and infrared tracker,and the corresponding algorithm is designed to obtain the dis⁃tance information,which mainly includes infrared and visible image matching and parallax positioning.Finally,the factors affecting the ranging are analyzed,and the algorithm is simulated under the set conditions.It is theoretically proved that this algorithm can ob⁃tain the distance of the target,provide the three-dimensional information of the target,and realize the positioning and tracking of the target.
