摘要
根据光电系统点目标探测概率、虚警概率公式,从信号和噪声的统计特性出发,推导了可见光相机对点源目标的作用距离公式。并综合考虑人眼的目标发现能力、目标的亮度对比度、观察等级和探测概率的要求,计算出面源目标的作用距离。为了便于计算,编制了相应的软件,并以高分辨率可见光相机为例,通过计算实现了对高分辨率可见光相机点源、面源目标的作用距离的估算。
By the formula of spot target detection probability, false alarm probability for photoelectric system, statistical characteris tics of signal and noise, the formula of visible light camera operating range for spot target is deduced. The operating range for extended arget is calculated by considering of the target finding ability of eyes, contrast of target luminance, discrimination level and detection probability. A software is developed for convenience calculation. Take high resolution visible light camera for example, the operating range of high resolution visible light camera for spot target and extended target by calculation are realized.
