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. Contents of the invention [0004] In...
