Abstract

An embodiment of the invention discloses a three-dimensional object surveying and mapping route planning method, a three-dimensional object surveying and mapping route planning device, remote controlequipment, a surveying and mapping unmanned aerial vehicle and a medium. The three-dimensional object surveying and mapping route planning method comprises the steps of: determining an approximate shooting model corresponding to a three-dimensional object to be surveyed and mapped according to plane information and height information of the three-dimensional object; generating a plane expansion diagram matched with the approximate shooting model, and determining a plane surveying and mapping route matched with the three-dimensional object in the plane expansion diagram; and mapping each planeroute point in the plane surveying and mapping route to a geographic coordinate system to obtain an actual surveying and mapping route matched with the three-dimensional object, wherein the actual surveying and mapping route is used for performing three-dimensional surveying and mapping on the three-dimensional object. The three-dimensional object surveying and mapping route planning method and the three-dimensional object surveying and mapping route planning device can reduce the cost of three-dimensional surveying and mapping and improve the efficiency of three-dimensional surveying and mapping.

Description

technical field [0001] The embodiments of the present invention relate to the field of route planning, in particular to a route planning method, device, remote control device, surveying and mapping drone and storage medium for three-dimensional object surveying and mapping. Background technique [0002] With the development of science and technology, aerial photography technology is widely used in all walks of life. For example, aerial photography technology can be applied in engineering surveying and mapping, which can help staff obtain reliable and clear data sources, and become an indispensable technology in future space surveying and mapping. [0003] At present, aerial photography and measurement is not limited to the surveying and mapping of the plane area, more is to survey and map the space objects, and finally build the three-dimensional model of the space objects. Specifically, a plurality of photos covering the appearance of the space object are obtained, and the...
