摘　　要：论文通过分析面阵式激光雷达扫描成像机理,建立飞行目标运动数学模型,采用双切片法对目标模型进行可见点提取,实现面阵式激光雷达对飞行目标的模拟观测扫描。受限于面阵激光雷达分辨率,仅可采集到目标表面部分点云,文中利用凸包算法、灰度图和深度像融合算法对目标点云进行图像增强和滤波处理,以利用缺失点云重构飞行目标轮廓。仿真实验表明,图像增强处理能使导弹弹体和轨迹更加清晰可辨,解决目标飞行速度较快造成的运动模糊和拖尾现象,为后续弹目交会参数解算提供技术支持。In this paper,the motion mathematical model of flying target is established by analyzing the scanning imaging mechanism of planar array lidar,and the visible points of the target model are extracted by the double slice method,so as to realize the simulation observation and scanning of flight target by planar array lidar.Limited by the resolution of the planar array lidar,only part of the target surface point clouds can be collected.In this paper,the convex hull algorithm,gray map and depth image fusion algorithm are used to enhance and filter the target point clouds,so as to reconstruct the flying target contour using the missing point cloud.The simulation results show that the image enhancement processing can make the missile body and trajectory more clearly distinguishable,and solve the motion blur and trailing phenomenon caused by the fast flying speed of the target,which provides technical support for the subsequent calculation of missile-target intersection parameters.
