摘要
为应对机场航站楼日益严峻的安防形势,本文分析了航站楼重点防护目标及主要的威胁类型,并结合威胁发生的主要地点确定航站楼内的重点目标及重点防护区域。针对重点目标及重点区域进行图像质量的量化分析,并综合安装位置、安装高度、安装角度、视野宽度等安装要求及镜头焦距等参数选择进行视野分析,进而得出满足要求的视野要求及图像质量要求。通过采用IP Video System Design Tool视频监控系统设计工具,并以航站楼安检通道为例进行分析,结论表明,上述设计方法能够设计出合理的摄像头布置及满足要求的视野,以有效应对航站楼安防威胁。
In order to deal with the increasingly severe security situation of the airport terminal,this paper analyzes the key protection objectives and main threat types of the terminal,and determines the key objectives and key protection areas in the terminal combined with the main location of the threat.The quantitative analysis of image quality is carried out for the key objectives and areas,and the field of view(FOV) is analyzed based on the installation requirements such as installation position,installation height,installation angle,view field width etc.and camera parameters such as lens focal length,so as to obtain the required FOV with an accepted image quality.Through the use of IP Video System Design Tool,and take a typical terminal security screening channel as an example for analysis,the result shows that the above design method is favorable in designing a reasonable camera layout and acceptable FOV,it can effectively respond to the terminal security threats.
