V2EX atmospheric correction

Atmospheric Correction

释义 Definition

大气校正:在遥感/成像处理中,为了消除或减弱大气(如气溶胶、水汽、散射与吸收)对观测信号的影响,把传感器接收到的“表观辐射/反射”尽量还原为更接近地表真实特性的过程。(常见于卫星影像、航空影像与光谱数据处理;在天文观测中也可指对大气影响的修正。)

发音 Pronunciation (IPA)

/tmsfrk krkn/

例句 Examples

The team performed atmospheric correction before mapping vegetation health.
团队在绘制植被健康状况之前先进行了大气校正。

After atmospheric correction, the satellite reflectance data aligned much better with ground measurements, improving the reliability of the analysis.
进行大气校正后,卫星反射率数据与地面实测值更加一致,从而提高了分析的可靠性。

词源 Etymology

atmospheric 来自 atmosphere(大气),词根与希腊语 atmos(蒸气/气体)相关;correction 来自拉丁语 corrigere(纠正、校正)。合起来即“对大气造成的影响进行校正/修正”,这一术语随着现代遥感与定量光学成像的发展而普及。
