The invention provides a ship load capacity calculation method based on target detection and a semantic segmentation algorithm. The ship load capacity calculation method comprises the steps of obtaining a draught video stream of a ship; obtaining one frame of draft image in the draft video stream, and extracting a water gauge mark area and scale character information from the draft image based on a preset target detection algorithm; determining waterline information of the ship from the water gauge mark area based on a preset pyramid scene analysis network PSPNet semantic segmentation algorithm and an edge detection algorithm; determining a draught value of the ship in the draught image based on the waterline information and the scale character information; obtaining a draught value of each frame of draught image in the draught video stream, constructing a draught value set, processing the draught value set, and obtaining a target draught value of the ship; and calculating the load capacity of the ship based
