Three-dimensional geographic information acquisition system

Abstract

The invention discloses a three-dimensional geographic information acquisition system. The system comprises a geographic information public server-side and a mobile measurement terminal; the geographic information public server-side provides the support for a mobile measurement terminal, is responsible for receiving picture and posture information acquired by the terminal to perform the construction and update operation of a three-dimensional model; the mobile measurement terminal is responsible for receiving and displaying the three-dimensional landscape data transmitted by the cloud side, an enhanced realistic display way is used for performing fusion display; and meanwhile, the factor-oriented geographic entity three-dimensional information acquisition work can be performed based on the terminal multisensory. The system realizes the fast, low-cost and efficient update of the disperse geographic entity change, effectively reduces the acquisition cost of the multi-dimension geographic information, can be directly applied to the field classification and quality inspection of the basic surveying, can realize the indoor work and field integrated novel production mode of the multi-dimension geographic information acquisition, the fast update efficiency and quality of the disperse geographic entity change data are promoted, and the application demand on the geographic information by the big data era is satisfied.

Description

technical field [0001] The invention relates to the technical field of information collection, in particular to a three-dimensional geographic information collection system. Background technique [0002] Geographic Information System (Geographic Information System or Geo-Information system, GIS) is sometimes called "geographic information system", which is a specific and very important spatial information system. It is a technical system that collects, stores, manages, calculates, analyzes, displays and describes the relevant geographical distribution data in the entire or part of the earth's surface (including the atmosphere) space with the support of computer hardware and software systems. Location and geographic information are both the core and the foundation of LBS. A simple latitude and longitude coordinate will be recognized and understood by users only after it is placed in specific geographic information and represented as a certain location, sign, or orientation. ...
