星载相机拍摄仿真可视化平台设计与实现

Design and Realization of A Spaceborne Camera Simulation Visualization Platform

为了对某星载相机空间拍摄任务进行仿真推演,采用对STK的控件进行二次封装的方法建立了空间飞行器及其相机运行的空间环境可视化仿真平台。该平台采用服务器/客户端结构,服务器模拟相机及其空间环境,客户端模拟地面站,并实时显示相机拍摄的图像。为减少服务器、客户端之间的网络流量,建立了工作副本,在维护工作副本的基础上,实现了客户端实时获取并显示服务器端仿真过程中星载相机拍摄的图像。结果证明,该平台仿真效果形象逼真并能满足实时性的要求。

In order to demonstrate the task of a spaceborne camera shooting,a visual simulative platform was built. It used STK control secondary encapsulation method. The platform can simulate the space environment,in which spacecraft and its camera run. The platform used server / client structure. The server simulate the camera and its space environment. The client simulate station and real-time display camera images.Working copy method was presented to reduce the network traffic between server and client. Based on working copy maintenance,the client can obtain and display real-time images. Images were taken from the spacecraft＇s camera which was simulated on the server. The result shows that the simulation is visual and realistic,and the platform can meet the re-quirement of real-time.
