摘　　要：为提升多台高速相机同时观测多个弹丸落点的布站合理性,以获取高精度落点参数,基于观测场景特点,提出了一种采用蝙蝠算法进行高速相机布站的方法。以双目测量机理分析为基础,构建多相机观测基础模型。通过确定相邻2台相机观测角度和相机与落点间距离为基础变量参数,构建目标函数和约束条件,采用蝙蝠算法对布站模型进行优化计算。仿真结果表明,与常规布站需要6台相机相比,本方法只需4台相机就能够完成全部落点观测,有效提高了资源利用率。本方法考虑了像素约束对布站的影响,优化时间平均为2.3 s;在满足像素要求的前提下,能够节省布站设备,且优化时间能够满足日常布站要求。In order to improve the rationality of multiple high-speed cameras observing multiple projectile landing points at the same time to obtain high-precision landing point parameters,based on the characteristics of the observation scene,this paper proposes a high-speed camera layout method using bat algorithm.The basic model of multi-camera observation is constructed based on the analysis of binocular measurement mechanism.By determining the observation angle of two adjacent cameras and the distance between the camera and the landing point as the basic variable parameters,the objective function and constraint conditions are constructed,and the bat algorithm is used to optimize the station model.The simulation results show that in comparison with the six cameras required for conventional station arrangement,the proposed method can observe all landing points with only four cameras,which improves the resource utilization.In addition,the proposed method incorporates the pixel constraints on station arrangement in the optimization process,and the average optimization time is 2.3 seconds.Basically,the proposed method can save the station equipment on the premise of satisfying the pixel requirement,and the optimization time can meet the daily station layout requirements.
