River channel sand mining recognition method and device, electronic equipment and storage medium

Abstract

The invention provides a river channel sand mining recognition method and device, electronic equipment and a storage medium. The method comprises the steps: determining a water system buffer area of ato-be-recognized region based on the water system data of the to-be-recognized region; based on the multi-source remote sensing data of the to-be-recognized area, determining the river channel type of each river channel in the water system buffer area; and if the riverway type of any riverway in the water system buffer area is a seasonal dry riverway, determining a riverway sand mining recognition result of the riverway based on an recognition method corresponding to the background type of the riverway. According to the riverway sand mining recognition method and device, the electronic equipment and the storage medium, the dynamic change characteristic of the seasonal riverway underlying surface is fully considered, different recognition methods are adopted for riverways of different background categories in a targeted mode for seasonal dry riverways, and then the riverway sand mining recognition accuracy is improved.

Description

technical field [0001] The invention relates to the technical fields of water environment science and remote sensing, in particular to a method, device, electronic equipment and storage medium for identifying sand mining in river channels. Background technique [0002] The ecological environment of the river channel involves many aspects such as the water environment and the animals and plants in the river. At present, due to the impact of unreasonable water use, river channel management and global changes, a large number of seasonal dry channels continue to appear, which in turn breeds more sand mining area. [0003] Because sand mining fields are generally distributed along with water systems, and each water system is relatively developed, and generally distributed widely in space, it brings great difficulties to the monitoring and management of sand mining fields. Remote sensing technology can dynamically acquire and detect the change information of the underlying surfac...
