Lake sediment deposition amount monitoring method and device, electronic equipment and storage medium

The invention provides a lake sediment deposition amount monitoring method and device, electronic equipment and a storage medium. The lake sediment deposition amount monitoring method comprises the steps that vector data and remote sensing image data of a research area are acquired; screening out remote sensing image data with the cloud cover smaller than a first set value from the remote sensing image data, and screening out remote sensing image data in a target time period from the remote sensing image data in combination with vector data; calculating an improved normalized difference water body index of each pixel in the remote sensing image data to obtain a ratio enhanced image; calculating a normalized segmentation threshold by adopting an Otsu method so as to distinguish a water body and a non-water body in the ratio enhanced image and obtain remote sensing image data; the water body area in the remote sensing image data is calculated, visualization and data analysis processing are carried out on the wa
