Fishpond recognition method and system based on high-resolution satellite remote sensing image and medium

The invention provides a fishpond recognition method and system based on a high-resolution satellite remote sensing image and a medium. The method comprises the steps that the high-resolution satellite remote sensing image is preprocessed to obtain reflectivity data including geometric positioning; based on the reflectivity data, performing processing by using bilateral filtering, OTSU algorithm segmentation and an opening operation image processing method to obtain an initial fishpond vector result; extracting a vegetation coverage vector result, an initial fishpond vector result and a vegetation coverage vector result by utilizing the NDVI based on the reflectivity data, and performing vector erasure operation; and carrying out smooth surface operation on the candidate fishpond vectors,and carrying out manual intervention to obtain a final fishpond extraction result. A high-resolution satellite remote sensing image is adopted, a series of image processing methods are adopted, a fishpond automatic extraction
