MBR (Master Boot Record)-based GPS (Global Position System) track map matching method

Abstract

The invention discloses an MBR (Master Boot Record)-based GPS (Global Position System) track map matching method. Portable GPS equipment is connected with a computer host. The MBR-based GPS track map matching method has the following advantages and active effects: 1, historical information and road network topology information are introduced, and a matching path is judged by using the distance and angle, thus, the matching precision is improved, and errors are reduced; 2, the MBR-based GPS track map matching method is simple and effective, capable of processing larger data volume and good in real-time property, the complexity of matching calculation is lowered, and the time efficiency is increased; 3, the fault tolerance property is better, and incorrect data input is allowed; and 4, error point filtering is realized, and the positioning accuracy is further improved.

Description

Technical field [0001] The present invention relates to new technologies of GPS (Global Positioning System), GIS (Geographic Information System) and computer software, specifically a new MBR-based GPS trajectory map matching method and its example system—the development of security performance assessment and patrol management system . Background technique [0002] At present, the management and supervision of security patrol personnel follow the traditional "management of people" model, and supervise whether the security guards are on duty, whether they are late and leave early without reason, whether they randomly hang around and chat, whether they change the patrol route privately, and whether they follow the time and the number of patrols. The actual operation is easily affected by human factors, so there will inevitably be blanks and loopholes in supervision, empty security patrols and missed inspections in the security patrol management work. In order to prevent the occ...

Problems solved by technology

The reason is: GPS signal receiving equipment is usually affected by weather, satellite conditions and the surrounding environment, especially in cities with high-rise buildings, portable GPS positioning equipment still has obvious measurement errors; track data is usually used GPS samples the location, which is also inaccurate, and its accuracy is affected by the sampling rate

The measurement error caused by GPS accuracy and the sampling error affected by the sampling rate seriously affect the accuracy of positioning and application requirements, resulting in a discrepancy between the actual position and the position recorded in the track data. On the one hand, it affects the display effect of the application, and on the other hand, it affects Data Mining and Extraction of Deep Information
