大气对迷彩颜色混色影响研究

摘要

The formula of watching color stimulation about the painting is reasoned out from the object col-or stimulation by considering the effect of atmospheric attenuate and atmospheric color. The watching color stim-ulation of four kinds of basic paintings in different distance is calculated under the best atmospheric vantage tak-ing no account of size. The results show that with the increasing of observation distance, the watching chromatic aberration of four kinds of paintings decreases rapidly and the decreasing extent also decreases rapidly. The watching chromatic aberrations of four kinds of paintings are all less than 3 L*a*b* at 16 km observation distance to produce color mixture.%综合考虑大气对可见光传输的衰减和大气气幕颜色的影响，根据物体颜色三刺激值计算公式推导出迷彩色的视在颜色三刺激值计算公式，在不考虑斑点尺寸影响，只考虑大气因素的情况下，选取最有利的观察条件，计算四种基本迷彩颜色不同观察距离的视在颜色三刺激值。结果表明，随着观察距离增大，四种迷彩颜色视在色差迅速减小，减小幅度也迅速减小，当观察距离为16 km时四种迷彩颜色视在色差全部小于3 L*a*b*色差单位，产生混色。
