Firstly , after describing the developing history and systemic characteristic of multi - sensor systems , this thesis sums up several fusion structure and analyses some concerned points of multi - sensor systems . in this thesis , the robot ’ s multi - sensor system is delaminated to three layers and separated into several models , and the design and implementation of these models ’ function is discussed and analyzed in detail 按照灵活性、可重用性、可扩展性、设备无关性等要求,采用自顶向下设计和自底向上开发相结合的设计方法,对整个多传感器系统进行了功能模块划分和结构分层,讨论了各层的功能和各个模块的设计方案。
The implementation of deltafile 3 . 0 can be divided into two modules ? real - time file system module and manage module for both facilities and drives . the real - time file system contains four parts ? system call api layer , file node manage layer , virtual file system layer , concrete file system layer , which perform the abstraction of the facility 实时文件系统模块包含系统调用api层、文件节点管理层、虚拟文件系统层、具体逻辑文件系统层四部分,主要完成与设备无关的数据存取接口抽象和各种文件系统标准的实现;设备与驱动管理模块包含逻辑设备管理层、物理设备管理层、设备缓冲区高速缓存层、设备驱动管理层四部分,主要完成外部存储设备管理及其驱动接口抽象功能。
In the last part , the whole course of the measurement is advanced . chapter three introduced some knowledge of digital image processing , including palette , grayscale and dib , but mainly talk about the structure of the bmp file . also we mainly introduced image transform method that we often use 第三步介绍了数字图像处理的基本知识，包括调色板，灰度图，设备无关位图( dib )等，并主要介绍了bmp文件的结构；以及图像处理中常用的一四川大学硕士论文些操作原理，例如滤波、二值化等等。
