【摘要】 通过对大量民航飞行事故的分析,提出了一种旨在降低进近着陆过程事故率的辅助指挥系统。从1980年至1996年,全世界最大起飞重量5700公斤以上的喷气式和涡轮螺旋浆运输机发生重大死亡事故621起,其中发生在进近着陆阶段的重大死亡事故287起,占46%。因此进近着陆(8分钟)是航空飞行器最容易发生重大事故的阶段之一,民航人将其视为“危险的8分钟”。而在这“危险的8分钟”中,进近阶段占108起,第五边进近占82起,着陆阶段占97起。 本系统在充分考虑目前塔台所能得到的信息的基础之上,着眼于未来的新航行系统,综合运用现代图像处理技术、通信技术和微电子技术的成果,为塔台的指挥和地面调动提供更全面、更准确的实时信息。对于非常情况下的着陆,在专家系统的帮助下,提供最佳的方案选择,以降低危险8分钟的事故率。系统主要由以下几个模块组成:图像处理模块、显示系统、外部数据接口、数据记录系统、中央计算机系统、专家系统、局域网等。 由于时间和专业面的限制,本论文仅就系统中的图像处理模块的关键技术作了较为深入的研究,其中主要包括图像采集系统的设计、图像传输系统、图像处理系统的设计,在解决图像重叠部分的融合时,提出了相关算法、距离判别法,并进行了实验。

【Abstract】 Under the analysis of a great deal of civil aviation accident, This command assistant system is brought forward which aimed to lowed the ratio of approach and landing accident reduction. From 1980 to 1996 , The amount of accident Jet plan and turbine aerotransport which taking off weight exceed 5700kg all over the world is 621 times. In which there were 287 times wretched accident in the approach and landing phase, occupying 46 percent. So approach-and-landing(eight minutes)is one of the most important phase to which aircraft liable occur serious accident, civil aviation people regard them as "dangerous eight minutes".In this system, Taking sufficiently into account the information that tower received, eyeing on new navigation system in the future,using the production of modern image process technology,communication and microelectronics technology,We give the tower full-scale and more accurate real time information . With the assist of the specialist system, even in the extraordinary landings, this system will give optimal scheme to reduce the ratio of accident.This system compose of several modules,the main parts of which as follows:image process modules;disply system;external data I/O ;data recorder system ; central computer system;specialist system;local web etc.Because the limit of time and speciality,in this paper I have only studied the sticking point of the image process modules,it includes the design of image collection system .image transferring system.and image processing system.
