The non-contact ocean wave observation based on shore station could be impacted on high accuracy of surf crest 2D coordinate in wave images. Focus on previous disadvantages such as lower speed and accuracy, a novel surf crest tracking algorithm is represented with crest collapse function which could terminate the tracking process through end point adjustment. The algorithm could not only process the concerned part of the wave image automatically with higher speed, but also record 2D coordinate of every point on the concerned surf crest and the connection between every two contiguous points accurately, which are very practicable in the non-contact ocean wave observation.
