从工程应用观点出发研究单平台多传感器数据融合系统(Data Fusion System ,DFS) 设计和实现。首先通过分析此类型DFS 的功能需求, 提出一种具有一定可伸缩性的系统结构; 然后运用面向对象的方法, 进行系统设计, 以确保系统本身的可扩充性及系统中所采用的算法和模块的可移植性; 同时也给出了一种确保系统实时性的多线程实现方案。 关键词: 数据融合;OO 设计; 多线程 Abstract: In th is paper, the design and imp lem en tat ion of one2p latfo rm m u lt i2sen so r Data Fu sion Sys2 tem are studied f rom engineering perspect ive.
