Ship Target Recognition Method from Low and Low and Medium Resolution Satellite Images
At present,low and medium resolution imaging reconnaissance satellites have become one of the impor-tant means of long-range intelligence assurance.However,the reconnaissance of maritime mobile ships by low and medium resolution imaging reconnaissance satellites suffers from the problems of target detection and identification,which greatly affects the effectiveness of intelligence usage.To address the above problems,this paper proposes a ship Kelvin wake extraction method based on Hoff transform for matching and identifying ship models.The average distance of Kelvin wake spike wave of different types of ships was obtained through simulation,which can effectively i-dentify the ship attributes in real remote sensing images,and the comparative analysis with the actual image data proves that the algorithm has certain feasibility.Therefore,the Kelvin wake extraction method based on Hough trans-form can basically achieve the recognition of target ship type under certain conditions and improve the recognition ac-curacy of maneuvering ship targets at sea by low and medium resolution imaging reconnaissance satellites.
