Design And Implementation Of Positioning Track Tracking System In Complex Scenes

With the growth of positioning requirements in complex scenes,adaptive navigation and positioning technology tends to develop multi-sensor and multitechnology integration.The data generated by positioning technology becomes more and more complex.It is easy to be confused for researchers and they cannot intuitively compare the data differences between different records of the same trajectory.Researchers lack intuitive verification methods and cannot directly judge the reliability of positioning.Based on the background,this project designs and develops a positioning trajectory tracking system in complex scenes.The system compensates for the positioning errors in complex scenes through error correction algorithms,and provides researchers with positioning results,positioning errors,the visual presentation of motion trajectories and other sensor data.It provides scientific researchers with a graphical presentation of the positioning data,which is used to observe the trend of the sensor data and compare differences of different records of the same trajectory.The system also provides the user with a picture of the current position for credibility verification.This dissertation is discussed in accordance with the software engineering method and the principle of using UML.In the requirements analysis,the user roles are divided into two categories:administrators and scientific researchers.The scientific research needs of scientific researchers are fully investigated and summarized.The functional requirements and non-functional requirements are described in detail in the form of use case diagrams and descriptions.In the outline design stage,based on the analysis of system requirements,user requirements are designed into functional modules,including registration and login module,user management module,real-time location tracking module,data transmission and processing module,positioning device management module,Positioning record management module and chart presentation module.The seven modules constitute the functional body of the system.In addition,this paper conducts database analysis and database table design through ER diagram,and performs page style design in the form of prototype diagram.In the detailed design and implementation stage,this paper elaborates the detailed design and implementation process of the system through the combination of class diagram and sequence diagram.In the test stage,the paper tests the function points in detail through test cases and fix them.This paper finally completes the analysis,design,development and test of the system.The system can basically meet the actual needs of researchers in the field of mobile positioning,and can be used as a professional visualization platform.
