本文从分析多光谱假彩色形成原理的基础上提出了假彩色的一般判别式,用地物目标的光谱特性曲线结合判别式的运算能预知假彩色的规律性。通过相应的标准密度级的合成,可得到地物目标的标准假彩色,以提供判读依据。文中提出了利用摄影处理过程中的非线性转换,达到增强假彩色的效果。并对当前普遍争议的问题进行了讨论。
Based on the analysis of the formation principle of multi-spectrum false color, this paper presents the general discriminant of false color, and predicts the regularity of false color by combining the spectral characteristics of object with discriminant. Through the corresponding synthesis of standard density level, we can get the standard false color of the object of the object to provide the basis of interpretation. The paper proposes the use of non-linear transformation in photographic processing to enhance the effect of false color. And discussed the issues that are currently widely disputed.
