Earthwork calculation method and system based on unmanned aerial vehicle oblique photography and storage medium

The invention discloses an earthwork calculation method and system based on unmanned aerial vehicle oblique photography and a storage medium, and relates to the technical field of unmanned aerial vehicle surveying and mapping, and the method comprises the following steps: building a ground surface model based on obtained aerial photography information; identifying a vegetation cluster area in the earth surface model; dividing each vegetation cluster area into an edge area and an internal area based on a preset division rule, and obtaining an edge vegetation height; matching each internal area with an adjacent edge area with the same vegetation type; executing different preset methods to obtain the regional vegetation height of the corresponding internal region; removing a vegetation cluster area on the ground surface model to form a ground surface model; and calculating the earthwork volume according to the ground model. The vegetation height of the internal area can be calculated according to the rule by cal
