The invention relates to a method for generating a ship track curve based on voluntary observation ship (VOS) data, in particular to a method for generating the ship track curve with a large number of discrete points. The method comprises the following steps: reading VOS; recognizing the voyage according to the VOS track points; arranging the VOS track point data; connecting the VOS track curves; correcting the connection of the track curves according to the obstacle-avoiding path design; generating the VOS track curve. Through adoption of the method, the problem that the ship track curve or ship route is extracted a little can be solved; the ship track curve generation method is provided; a large number of discrete VOS point data can be used for generating into a continuous ship track curve which is beneficial for mastering the regional marine traffic distribution conditions and monitor ship behavior so as to ensure the marine traffic security as well as providing decision-making reference for the marine administrative authority; the method is of great significance on protecting the life and property of people, protecting the marine environment and ensuring the national core strategic interests.
