摘　　要：为了实现漫反射激光全向激光告警过程中定位敌方激光源的目的,采用软件方法,结合几何光学原理及机器视觉概念,引入R、α、β、d、θ、φ、ψ、δ等8个未知参量描述典型战场环境下敌方激光源、照射于某平台平面上的漫反射激光光斑以及我方全向激光告警系统鱼眼镜头三者之间的空间几何位置关系,推导像面上光斑轮廓曲线的解析形式,再结合像面上光斑坐标信息,反推得到具体情况下的8个参量,从而可以确定这种空间位置关系,并定位敌方激光源位置,达到激光告警的目的。通过实验验证,结果显示全向激光告警设备能够实现对漫反射激光光斑的告警。To locate the enemy laser source in omni-directional laser warning based on diffuse reflection detection based on geometrical optics principles and machine vision concepts,this paper introduced 8 unknown parameters including R,α,β,d,θ,φ,ψ,δ to describe the spatial position relationships among enemy laser source,the laser spot radiated on one flat plane and our omni-directional laser warning fish-eye lens in typical battlefield environment,deduced the analytic expression of the laser spot contour on image surface,and acquired the 8 parameters from the spot coordinates data on image surface.Thus the spatial position relationships were obtained,the enemy laser source was located,and laser warning was achieved.The experiment result verified the feasibility of the omni-directional laser warning devices.
