At present, GOCI satellite is the only means to monitor the drift of sea ice in a wide range. The high temporal resolution makes it fit for monitoring Marine phenomenon and process in time series. It improves the possibility of obtaining a high quality image in a short period of time. GOCI satellite is with great applied potentiality and value. In order to use the information of GOCI satellite image effectively, Harris algorithm and SIFT algorithm are combined to extract the feature points of image of sea ice and match images. Extraction of drift direction and speed of sea ice of the Huanghai and Bohai Sea is realized in this paper.
