可见光云图 meaning in English
visible cloud imagery
visual cloud pictures
visual-light cloud picture
Examples
- The dynamic threshold algorithm is based on a fact that measurements at the chosen channels are in different scopes between the different observation objectives ( here as earth surface and cloud )
双通道动态阈值法的依据是，在可见光云图和红外云图上，云和地物的值域是不同的。 - Solar eclipse happens occasionally so that an obvious shadow appears on the satellite vis imagery . thus , the information on the imagery could not be analyzed and used . for this reason , it is necessary to correct the region of solar eclipse shadow on the cloud image
日食时有发生，在受其影响的区域，卫星可见光云图上会出现明显的阴影，使得云图上的信息无法得到分析和利用，这就需要对云图进行订正处理。 - The infrared radiative fluxes emitted by earth - atmosphere system comes from the infreared pictures and the solar radiative fluxes reflected by earth - atmosphere system comes from the visible pictures , then the relationship between the surface net radiation and the satellite retrieval radiation is statistically discussed in this paper
由红外云图反演出地气系统发射红外辐射，可见光云图反演出地气系统反射的太阳辐射，然后采用多元统计的方法讨论了地表净辐射与卫星反演出的辐射值之间的关系。 - This paper is composed of two parts including 5 chapters . in the first part ( including chapter 2 ^ 3 ) , this paper explains an improved geometry - model method to eliminating eclipse shadow , using satellite imaging theory and projection theory to convert plane rectangular coordinates into rectangular spherical coordinates . otherwise , through studying eclipse ' s shape and size , this paper uses a math - function - model to eliminating eclipse shadow
本文共有五章，主要内容分为两部分；第一部分包括第二、三章的内容，利用可见光云图成像原理以及点的投影法，将平面云图投影到三维直角坐标的球面上，对用于云图阴影订正的原几何模型法加以改进，得到改进的几何模型法，并进行日食阴影订正实验；本文还利用数学函数模型法，通过研究月球在地球表面投射阴影的形状及其受影响程度，从另一方面进行可见光云图日食阴影的订正实验研究。
