摘要
实时、精细化的海表流场测量对海洋学研究有着重要意义。在简要对比各类海表流场测量方法的基础上,详细介绍了利用水色遥感图像测量海表流场的最大相关系数法(MCC),并利用亚像素方法对该算法进行了有效改进,同时利用本文算法对东海黑潮海域的海表流场进行了分析,验证了本文算法的可靠性。
Accurate and real-time measurement of sea surface currents is significant for the study of physical oceanography.The block matching algorithm of maximum cross-correlation （MCC） is presented in detail in the paper,and sea surface currents can be obtained by analyzing ocean color remote sensing images with MCC algorithm.To improve the accuracy,the sub-pixel operation is applied to the MCC results.The reliability can be verified by the measurement of the Tsushima Strait sea area.
