摘要
空间视觉测量的覆盖特性可以用视场和作用距离两项指标来描述。文中从空间几何的角度,建立了视场指向固定、视场以一定的周期变化规律和以目标为指向的3种覆盖模型,并利用MATLAB软件进行仿真分析。结果显示,视场指向固定时和以一定的周期变化规律时的覆盖率低于以目标为指向的覆盖率,以目标为指向时的覆盖率与相机和探测光标的相对距离有关,不受视场的限制。
Coverage performance of space visual measurement can be marked by field of view（FOV） and working distance.In this paper,three overlay models not only are put forward based on space geometry,which are differentiated with fixed FOV,periodic FOV and targeted FOV,but also are simulated based on MATLAB software.Simulation results indicate that coverage rates with fixed FOV and periodic FOV are lower than targeted FOV,and coverage rate with targeted FOV is not related to FOV but the working distance.
