2D-3D data linked display method and system

Abstract

The invention relates to a 2D-3D data linked display method and system. The method comprises the steps that 1) map data and target object information are obtained, the target object information comprises coordinate information of a target object, and the coordinate information of the target object corresponds to a calibration coordination point in the map data; 2) a 3D map and a 2D map matching each other are generated according to the map data, and according to the coordinate information of the target object, the target object is displayed in a position corresponding to the calibration coordination point in the 3D map in the form of a 3D model, and is displayed in a position corresponding to the calibration coordination point in the 2D map in the form of a 2D model; and 3) the 3D map including the 3D model and the 3D map including the 2D model are displayed in calibration display areas respectively. According to technical schemes of the invention, the background can display target object information in the front environment with better effect, the target object information is processed more accurately according to a real-scene environment, and waste of labor and material resourcesis avoided.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a two-dimensional and three-dimensional data linkage display method and system. Background technique [0002] With the development of GIS (Geographic Information System) technology, more and more fields use GIS to realize the information linkage between front and rear. In fields such as security monitoring, multiple monitoring devices and alarm devices may be arranged on the front site, and the display interface of the rear host usually displays the relative position and real-time status of each device in the form of a two-dimensional map. With the further expansion of GIS application scenarios, due to the fact that the actual geographical environment of the front site may be more complex, the influence of the geographical environment on the monitoring device and other devices cannot be fully considered through a single form of map display, which may cause false ala...

AI Technical Summary

Problems solved by technology

With the further expansion of GIS application scenarios, due to the fact that the actual geographical environment of the front site may be more complex, the influence of the geographical environment on the monitoring device and other devices cannot be fully considered through a single form of map display, which may cause false alarms, etc. happened

Directly entering the front site without conducting preliminary analysis based on the actual environment may cause waste of manpower and material resources
