遥感图像真彩色融合问题中的彩色约束方程

The Color Constraint Equations Adopted in True Color Fusion of Remote Sensing Image

根据遥感真彩色融合的物理机制,推导出RGB彩色模型中的约束方程,引入YVC彩色模型,提出不同分辨率遥感图像彩色融合必须满足的独立彩色约束方程,应用一次和二次多项式展开导出相应的近似解。通过进行计算机模拟和遥感实际试验,结果表明,二次多项式近似解可明显改善对道路地物的融合效果。

Firstly a color constraint equation in the RGB color model was formulated in the paper based on the physical mechanism of color fusion for remote sensing image. Then the independent color constraint equation was proposed by introducing the YVC color model that must be suitable to color fusion of remote sensing images with different resolution. And the approximate solutions of the color constraint equations might be obtained by adopting the linear and quadratic equations. The computer simulation and the actual remote sensing experiment results showed that the color fusion effect could be significantly improved by using the approximate solution by applying the quadratic equations.
