Abstract

The invention discloses a municipal engineering measurement positioning method and system, and the method comprises the steps: obtaining urban geographic information data, building a GIS electronic map, building a BIM model of a building and a structure to be built based on the urban geographic information data, uploading the GIS electronic map and the BIM model to an AR measurement platform for position information marking, and performing simulation measurement and positioning on the BIM model according to a position marking result, determining position coordinates of buildings and structures, and performing field marking based on the position coordinates. The system comprises a data acquisition module, a GIS database, a BIM model generation module and an AR measurement positioning module. According to the municipal engineering measurement positioning method and system, the BIM technology and the AR technology are combined through the AR measurement platform, the standard points and the coordinate control points are marked on the electronic map of the AR measurement platform, the building is positioned in combination with the BIM information model, and finally the result is put into the scene, so that the process is more efficient and refined.

Description

technical field [0001] The invention belongs to the technical field of engineering survey, and in particular relates to a municipal engineering survey and positioning method and system. Background technique [0002] With the development of my country's economy, the process of urbanization is accelerating, and the construction of municipal infrastructure is becoming more and more intense. We refer to the measurement work required in the design, construction, completion and operation management stages of various public facilities in the city as municipal engineering measurement. At present, the measurement of individual municipal projects is mostly carried out on the basis of urban survey control network and large-scale topographic maps of the city. The main axis points of various municipal projects adopt the unified coordinate and elevation system of the city. The urban road network is the skeleton of the city's plane layout, and the land use scope of urban projects is often...
