辐射度学 meaning in English

radiometry

Atmospheric attenuation of scene contrast is studied theoretically on the basis of radiometric principles , and the relationships between the measured maximal detection range for a target and visibility distance under two possible conditions are obtained
根据辐射度学原理，从理论上研究景物对比度在大气传输中的衰减，得到了在两种可能的条件下所测得的目标最大探测距离与能见距离的关系。
First , this thesis studied the performance of the image processing system , such as the color principle of ccd camera , the radiation transfer principle of system , geometry optics model of system and so on . then the system hardware frame was established
首先，本文充分研究了火焰图像处理系统中彩色ccd的工作原理、色度学原理、成像系统的辐射度学原理、几何光学模型以及数字化成像原理，并建立了燃烧可视化监控系统的硬件框架。
