The invention discloses a hull profile design method based on a convolutional neural network, and relates to the technical field of ships. The method comprises the following steps: carrying out data standardization processing on ship type geometric data of a sample ship to construct a geometric feature array of the sample ship; using the geometrical characteristic array of the sample ship as input, and using the hydrodynamic performance data as output; performing training based on a convolutional neural network to obtain a ship type performance prediction model; using the ship type performanceprediction model for carrying out hydrodynamic performance data prediction, data mining and sensitivity analysis on a target ship with known ship type geometrical data; optimizing the ship body molded line of the target ship according to the sensitivity analysis result, so that the optimization efficiency can be improved. According to the method, the ship form can be rapidly designed, an effective parameter-free ship geometric expression and analysis method is provided, data difference caused by a parameterization process in ship form line analysis is avoided, and the method is high in universality and suitable for most mainstream ship forms.
