Lake sand dredger remote sensing identification method

Abstract

The embodiment of the invention provides a lake sand dredger remote sensing identification method which comprises the following steps: firstly, acquiring a remote sensing image of a working area, andextracting a lake area of the working area based on the remote sensing image; then obtaining a non-sand-mining area in the lake area, and determining a mobile facility area in a remaining area obtained after the non-sand-mining area is removed from the lake area; and finally, determining a sand mining area in the lake area, and determining a sand mining ship in the working area based on the sand mining area and the mobile facility area. The identification of the sand dredger can be accurately realized to facilitate analyzing and research of the sand dredger information of lakes.

Description

technical field [0001] The invention relates to the technical field of water environment research, in particular to a remote sensing recognition method for a lake sand mining ship. Background technique [0002] Sand mining in lakes has always been the most concerned issue in the academic circles and related management departments. The ecological environment of lakes involves many aspects such as water environment, animals and plants in rivers, etc. At present, due to the rigid demand for production and construction such as roads and building facilities, a large amount of sediment needs to be obtained, thus creating more sand pits. [0003] Since the sand mining process or after sand mining will inevitably have a certain impact on the water area or the near-shore ecological environment, the sand mining field must be licensed for mining. However, due to the large number of lakes, it is impossible to effectively monitor and manage sand mining sites. In addition, due to the re...

AI Technical Summary

Problems solved by technology

However, sand mining, especially for the sand mining information of lakes, because the lake has a wide water surface and is also an important channel or place for freight, fishing, etc., it is difficult to distinguish freight, fishing boats and sand mining ships by conventional methods
