Example Embodiment

[0059] Example one:

[0060] figure 1 Is a flowchart of a topographic map surveying and mapping method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0061] Step S12: Determine a survey area of ​​the terrain to be surveyed and mapped, where the survey area is a built road within the terrain to be surveyed and mapped;

[0062] In the embodiment of the present invention, in order to perform topographic mapping of the terrain to be surveyed and mapped, the survey area of ​​the terrain to be surveyed and mapped must first be confirmed. In the present invention, the built roads in the terrain to be surveyed and mapped are used as the survey area.

[0063] Step S14, using the vehicle-mounted three-dimensional laser scanning measurement system, surveying and mapping equipment and field repair survey operation methods to carry out topographic map surveying and mapping of the survey area to determine the topographic map...

Abstract

The invention provides a topomap surveying and mapping method and device, and relates to the technical field of geographic information measurement. The method comprises the steps that a measuring areaof a to-be-surveyed and mapped terrain is determined, wherein the measuring area is a constructed road in the to-be-surveyed and mapped terrain; and the measuring area is subjected to topomap surveying and mapping by adopting a vehicle-mounted three-dimensional laser scanning measuring system, surveying and mapping equipment and a work mode of field work repair measuring, and a topomap of the measuring area is determined. According to the topomap surveying and mapping method, the vehicle-mounted three-dimensional laser scanning measuring system is mainly used to scan the measuring area, internal work personnel process data obtained by scanning to obtain a topomap sketch, and field work personnel perform repair measuring; the method realizes that most of work of topomap surveying and mapping is converted into internal work from field work, so that the field work cost is greatly reduced; and the three-dimensional laser scanning measuring system takes a vehicle as a platform, so that themeasuring area is convenient to enter, work conditions are loose, and the technical problems that an existing large-scale topomap production mode is high in cost and work is affected by various factors are relieved.

Description

technical field [0001] The invention relates to the technical field of geographic information measurement, in particular to a topographic map surveying and mapping method and device. Background technique [0002] At present, the production methods of large-scale topographic maps mainly include all-field digital mapping and aerial photogrammetry. Although these two production methods have their own advantages, they also have some disadvantages: all-field digital mapping mainly relies on a large number of manual work in the field. In the field, the work intensity is high, the operation cost is high, and the efficiency of manual collection is low; aerial photogrammetry is greatly affected by factors such as weather and terrain, and equipment rental costs are expensive. [0003] To sum up, the existing production methods of large-scale topographic maps have the technical problems of high cost and the operation is affected by many factors.
