摘 要：Small targets detection is one of the key technical problems in these fields such as maritime surveillance and disaster *** order to find the target as early as possible,the small target detection algorithm based on sea-sky line extraction is generally adopted,and the accurate extraction of the sea-sky line becomes the basis of the small target detection in the *** the panoramic sea images acquired by the catadioptric panoramic vision system,the sea-sky line extraction algorithm is studied in this *** specificity of panoramic vision system creating images makes sea-sky line in a panoramic image an approximate circle.A detection algorithm based on gradient direction is proposed to extract accurately the circular sea-sky *** results show the efficiency and superiority of the proposed method in this paper.
