Ship moving target detection method and system based on efficient space-time characterization and alignment

The invention belongs to the technical field of image processing, and discloses a ship moving target detection method and system based on efficient space-time representation and alignment. The method comprises the following steps: firstly, inputting a single-scene multispectral image, and segmenting the single-scene multispectral image into slice images; and then, inputting the slice image into a trained moving target detection network model based on efficient space-time representation and feature alignment, and during processing, processing through a local motion feature alignment module, a multi-level space-time convolution self-attention backbone network, a double-feature pyramid, a detection head and other modules in sequence to obtain a large ship moving target detection result. The method provided by the invention can improve the distinguishability between the ship moving target and similar interferents such as broken clouds, islands and the like by mining the spatio-temporal information contained in th
