Label information system capable of gathering geographic position using label terminal and information acquisition method

Abstract

The invention discloses a system using marking terminal to collect geography marking information and an information acquisition method, the system comprises one or more geography marking information servers, and the geography marking information servers are connected with at least a marking terminal through wired or wireless network. The marking terminal comprises a central processing unit, a communication control unit, a position information acquisition unit and a storage unit, wherein the marking terminal obtains a position of a marking object, position information is sent to the geography marking information servers, the geography marking information servers store and manage the position information of the marking object, which is reported by the marking terminal, and a query interface of the marking information is provided for users or location-based service application. Using the geography marking information acquisition system, the position information of the masking object is obtained not through mapping on the spot, and the system can provide basic data for the location-based service application of electronic maps and vehicle navigation.

Description

technical field [0001] The invention relates to a geographic labeling information collection system, in particular to a geographic location labeling information collection system and an information collection method using a labeling terminal. Background technique [0002] The maps used in daily use contain a large amount of labeling information. The content of the labeling information includes the name and location of the labeling object. Manual analysis and labeling are used to complete the production of maps. Maps require a lot of manpower and take a long time to complete. Even today, when electronic maps are becoming more and more common, this situation has not been fundamentally changed. This labeling method There are the following defects: [0003] 1. The cost of geographic information collection is high. According to statistics, 70% or more of the cost of an electronic map is used for surveying and mapping to obtain information such as the location of marked objects t...

Problems solved by technology

[0003] 1. The cost of geographic information collection is high. According to statistics, 70% or more of the cost of an electronic map is used for surveying and mapping to obtain information such as the location of marked objects to establish a geographic database, especially in the application of satellite, aerial photography and other technologies. In some cases, the information needs to rely on on-site surveying and mapping, and the input of manpower and material resources is more considerable, and the cost is more expensive;

[0004] 2. Geographic information is not updated in time. my country is in the stage of large-scale construction. A large number of roads and buildings are completed and delivered every year. It is estimated that 30% to 40% of the information in the electronic map needs to be updated every year. It is necessary to keep the electronic map markers in line with the actual consistency is difficult

Because the electronic map is not updated in time, people's judgment will be misled by the outdated electronic map;
