Abstract

Meteorological satellite is using landmarks in remote sensing images for automatic navigation.Coastline detection is an important step in the process.Through matching the detection result with the corresponding region of global standard landmark library,the offset is obtained to adjust the posture of satellite.Considering the characteristics of meteorological satellite image navigation process,a new method is proposed to detect coastline in the infrared channel.Cloud detection is made first,and a C-V model which is initialized by information in standard landmark library is used to promote the evolution of the curve.Experimental results show that the method fits meteorological infrared channel well and has advantages in efficiency,stability and accuracy.

地球同步卫星遥感影像中的海岸线检测

气象卫星利用遥感影像中的地标进行自动导航。海岸线探测是这一过程中的重要步骤。将检测结果与全球标准地标库对应区域进行匹配，得到偏移量，用于调整卫星姿态。针对气象卫星图像导航过程的特点，提出了一种红外通道中海岸线探测的新方法。首先进行云检测，利用标准地标库中的信息初始化C-V模型，促进曲线的演化。实验结果表明，该方法较好地适应气象红外通道，具有高效、稳定、准确等优点。

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
