Method for identifying ship type based on adaptive chain code

The invention provides a method for identifying a ship type based on a self-adaptive chain code. The method comprises the following steps: S1, acquiring a ship picture of a ship to be identified; s2, extracting an outer contour line of a to-be-identified ship in the ship picture; s3, calculating a s...

description	The invention provides a method for identifying a ship type based on a self-adaptive chain code. The method comprises the following steps: S1, acquiring a ship picture of a ship to be identified; s2, extracting an outer contour line of a to-be-identified ship in the ship picture; s3, calculating a self-adaptive chain code of the outer contour line of the ship to be identified, and recording the self-adaptive chain code as a first self-adaptive chain code; s4, respectively calculating the similarity between the first adaptive chain code and each adaptive chain code in a preset ship type library, marking the adaptive chain code in the ship database as a second adaptive chain code, and taking the second adaptive chain code with the highest similarity as a target chain code, and S5, obtaining a corresponding ship type in the ship type library according to the target chain code, and taking the obtained ship type as the ship type of the ship to be identified. The method can effectively improve the recognition rate,
