The invention provides a sea wave height detection method, medium and system based on semantic segmentation, and belongs to the technical field of sea wave height detection.The sea wave height detection method comprises the steps that a near-shore camera obtains multiple pieces of sea wave image data, and a training data set is formed after preprocessing; a GS-SegFormer semantic segmentation model is utilized, and the model adopts an improved self-attention mechanism, a Ghost module and a SimAM attention mechanism to segment a sea wave image to be detected to obtain a pixel level boundary of sea waves. Gaussian filtering smoothing processing is carried out on the segmented image, noise is reduced, pixel information is converted into an actual distance according to camera parameters, and finally the actual height of each sea wave pixel is calculated. According to the method, sea wave features are identified through a deep learning model, and the actual height is calculated by combining camera parameters. The invention solves the technical problem that the precision of subsequent height calculation is influenced because the real contour of the sea wave cannot be accurately segmented by the existing sea wave height detection method.
