Method, system and equipment for monitoring mining output in open-pit mines based on remote sensing images

Abstract

The present application provides a method, system and equipment for monitoring the mining volume of an open-pit mine based on remote sensing images, and belongs to the field of mining area monitoring technology. The method can generate a digital elevation model of the working area based on multiple stereo image pairs of working areas and a preset DEM generation tool, and determine the geo-referenced image group of different preset monitoring periods according to the working area reference image and the specified remote sensing image. Based on each selected same-name point obtained by the user operation, the horizontal registration error information of the geo-referenced image group is determined to perform a first registration processing on the digital elevation model of the working area. Based on each preset control point, the vertical registration error information of the digital elevation model of the working area is determined to perform a second registration processing on the corresponding digital elevation models of each working area; based on the digital elevation models of each working area after the second registration processing, the fill and excavation volume of the monitoring working area between each preset monitoring period is determined, and the fill and excavation volume of the monitoring working area is sent to the user terminal.
