The invention discloses a ship resistance forecasting method based on image learning, and belongs to the technical field of ship equipment, and the method comprises the steps: taking a ship form as a sample which comprises a ship form image and a label; a ship type image is used as input to express ship type features, the content of the ship type image is a side view of a ship type, and the color or gray level of pixel points represents width information of ship body curved surface type value points at the corresponding positions; labels in the samples are resistance data corresponding to corresponding ship types; constructing a convolutional neural network model by adopting a deep learning framework; and inputting the ship type image of the ship type sample and the corresponding label into a convolutional neural network model for training to obtain parameters of the convolutional neural network model so as to input the ship type image of the new ship into the convolutional neural network model to obtain a resistance forecasting result when the resistance of the new ship is forecasted. According to the method, the images are used as input to express the ship shape features, and the defects that a previous approximate model method is not high in universality and expansibility are effectively overcome.
