地基可见光/红外全天空成像仪数据融合
Data Fusion for Base Ground Visible/Infrared Whole Sky Imager
摘要
Abstract
Using 60 m base-line binocular visible imager and scanning infrared imager,a dual-band whole sky cloud measurement and control system was built.According to the principle of binocular distance measurement,the binocular visible imager can accurately obtain the height of cloud base,and through comprehensive three-dimensional scanning the whole sky visible light cloud pictures were obtained.The scanning infrared imager can measure the temperature of cloud base and inverse the height of cloud base on the basis of the principle of atmospheric radiation transmission,and through comprehensive three-dimen-sional scanning,the whole sky infrared cloud pictures were obtained.Combined with the height of cloud base and the real-time correction of atmospheric temperature vertical decline rate,the binocular visible im-ager could measure the height of cloud base,improve the accuracy of inversion the height of cloud base of the scanning infrared imager,achieving the height of cloud base data fusion.Based on image fusion tech-nology of wavelet multi-resolution analysis,the whole sky visible light and infrared cloud image are fused, improving cloud computing accuracy under the fog-haze conditions.Thus,cloud base height and cloud cov-er could be observed day and night.关键词
