Ship berthing control system and control method based on image processing

The invention discloses a ship berthing control system and control method based on image processing, and the control method comprises the following steps: S1, obtaining the image information of a ship; S2, obtaining a course angle correction value of the ship according to the image information, so as to guide the ship to enter a preset channel; S3, obtaining the distance information of the ship according to the image information, judging whether the ship arrives at a berth region or not according to the distance information: carrying out the berthing of the ship if the ship arrives at the berth region, or else returning to step S2. According to the invention, mark objects are set on the ship and at a shore, and a shore image vision system is built for providing the azimuth and distance information of the ship. The image is used for estimating the course, so as to replace the course information provided by TCM2, thereby achieving the automatic sailing control which employs the image processing to provide the navigation information in the whole process of entry and berthing. The method is convenient for control, is small in error angle, and is higher in control precision.
