Novel topographic map surveying and mapping method

Abstract

The invention relates to a novel topographic map surveying and mapping method, a ground robot is adopted to be combined with an unmanned aerial vehicle for surveying and mapping, communication connection is conducted between the ground robot and the unmanned aerial vehicle, the method comprises the steps of unmanned aerial vehicle measurement and ground robot measurement, and the unmanned aerial vehicle measurement comprises the following steps that a ground reference signal station is established; an unmanned aerial vehicle airborne positioning system and a ground reference signal station arecalibrated; the unmanned aerial vehicle flies to a fixed point, and measurement is prepared to be started; the unmanned aerial vehicle carries out flying shooting sampling in an up-down fluctuation mode; real-time corresponding storage on the shot sampling data and unmanned aerial vehicle positioning data of the airborne positioning system is performed, and the data is transmitted to a ground reference signal station to obtain an unmanned aerial vehicle measurement image; the measurement of the ground robot is completed, and a ground robot measurement view is obtained; and the unmanned aerialvehicle measurement view is combined with the ground measurement view to obtain a measurement view of the topographic map.

Description

technical field [0001] The invention belongs to the technical field of surveying, in particular to a method for surveying and mapping topographic maps. Background technique [0002] Topographic map refers to the projection map of surface relief and geographical location and shape on the horizontal plane. Specifically, the method of horizontally projecting the objects and landforms on the ground (projecting along the vertical line onto the horizontal plane), and shrinking them onto the drawings according to a certain scale, this kind of map is called a topographic map. [0003] It is quite complicated for people to see topographic maps that reflect the shape and appearance of the earth's surface. Whether it is a mountainous area with undulating topography or a watery plain with dense rivers, lakes and ponds, the various landforms and feature symbols on the map accurately reflect the actual situation on the ground. How are they mapped out? [0004] This begins with clearly ...

Problems solved by technology

[0005] Most of the existing topographic map measurements are completed by artificial height measurement. With the popularization of UAV technology, there are also a small number of UAVs that cooperate with humans to measure. However, UAVs measure at high altitudes, resulting in ground The description of the situation is not objective, only two-dimensional images can be presented, and a large amount of surveying is still required by manpower. Therefore, in order to improve work efficiency, it is necessary to provide a new topographic map measurement method that combines robots with drones, so that Reach the environment that humans cannot reach, and draw topographic maps
