Embodiment 1

[0020] This embodiment, as the best embodiment of the present invention, discloses a remote sensing surveying and mapping technology suitable for urban suburbs, which is characterized in that it includes the following steps:

[0021] A. Select multiple coordinate points according to the time of detecting the target, and set the GPS base station at the coordinate point, and plan the surveying and mapping route with the set GPS base station;

[0022] B. Release the surveying and mapping UAV, and command the UAV to carry out flight measurement according to the planned path; at the same time, correct the flight route through the GPS base station;

[0023] C. Turn on the laser mapping radar on the UAV, perform overlay scanning and mapping of the area to be measured, and use the coordinate points in step A as the base point to form a three-dimensional model of the area.

[0024] D. Turn on the panoramic camera on the drone to measure the area, and use the coordinate points in step A...

Embodiment 2

[0028] In this embodiment, as another preferred embodiment of the present invention, the coordinate points in the step A are preferably open places with houses, roads or obvious landmarks.

[0029] The coordinate points are arranged in a W shape, and the longitudinal spacing of the coordinate points is 100m, and the horizontal spacing of the coordinate points is 50m.

[0030] The flying height of the drone is 50m.

Abstract

The invention discloses a remote sensing mapping technology for city suburbs; the method uses a laser mapping radar and a panorama camera to carry out remote sensing mapping on two sides of a mappingregion, defines a mapping path and sets a plurality of coordinate points so as to fast compare two mapping results, thus fast and accurately mapping most mapping points; finally, the method uses a manual mapping mode to supplement-map points with larger errors in the mapping process or points with no mapping data, thus greatly improving the city suburb fast and accurately mapping.

Description

technical field [0001] The invention relates to the technical field of remote sensing surveying and mapping, in particular to a remote sensing surveying and mapping technology suitable for urban suburbs. Background technique [0002] Suburban surveying and mapping is related to urban development planning, which is reasonable enough to provide important data support for urban development decisions. However, compared with urban surveying and mapping, urban suburban surveying and mapping is more affected by natural terrain and vegetation, making its measurement more difficult. , the accuracy of surveying and mapping is lower; therefore, improving the quality of suburban surveying and mapping has important practical guiding significance for the development of suburban planning. Contents of the invention [0003] Aiming at the defects of high measurement difficulty and low precision in the prior art, the present invention discloses a remote sensing surveying and mapping technol...
