According to the imagebased visual servoing(IBVS) method, a virtual camera is constructed to express image moments of the tracking target.展开更多
文摘Visual C＋＋6.0是由 Microsoft 公司推出的一款面向对象的计算机程序开发工具，是编程入门的良好编译工具，在 Windows 环境下很常用，是使用最广的开发工具。AOS 是高级在轨系统（Advanced Orbiting Systems）的缩略词，主要用来达成航天器与地面站之间的双向传送。本文中应用 Visual C＋＋6.0程序设计软件，根据 AOS 空间包提取的方法，给出实验仿真结果。
文摘介绍在Visual C＋＋6．0环境下的两种Oracle开发接口：ADO（ActiveX Data Objects，AetiveX数据对象）与Pro＊C／C＋＋，其中ADO是一组由微软提供的COM组件，它通过使用OLEDB这一新技术实现了以相同方式可以快捷、便利地访问多种类型数据库数据，扩大了应用程序中可使用的数据源范围，Pro＊C／C＋＋是利用在C／C＋＋内嵌入的SQL语句来访问数据库数据，使用它可以开发出满足各种复杂程度的应用程序，并可有效提高应用程序的执行速度。通过设计实验，分别采用这两种方式完成数据库初始化、数据录入等工作，通过对比两种方式的实现分析两种方式的特点，并最终总结出两种方式各自的优缺点与适用范围。
