Object height measuring method and device based on unmanned aerial vehicle

The invention discloses an object height measurement method and device based on an unmanned aerial vehicle, and the method comprises the steps: controlling the unmanned aerial vehicle to sail to a height measurement region matched with a to-be-measured target when a height measurement instruction for the to-be-measured target is received; based on the height measurement equipment combination of the unmanned aerial vehicle, height measurement data corresponding to the to-be-measured target are collected, the height measurement data comprise boundary point heights corresponding to boundary points of the to-be-measured target, and the boundary points at least comprise upper boundary points of the to-be-measured target; and determining the object height of the to-be-measured target according to the height measurement data. It can be seen that the unmanned aerial vehicle can be controlled to sail to the corresponding height measurement area to measure the object height of the to-be-measured target, so that object
