半自動的室內(nèi)定位與導航
[Abstract]:In order to adapt to the increasing population density and the process of high speed modernization, the modern architecture is not only multifunctional, but also has complex internal structure. When people move in large buildings with complex interior environment, it takes a long time to locate their own position and find the target position. Although the satellite positioning system using GPS for real time outdoor navigation has been widely used, it is restricted by the fact that the satellite signal can not penetrate the buildings. The same navigation method can not be directly migrated to indoor environment navigation applications. Therefore, in recent years, experts and scholars have studied many indoor positioning and navigation technology and solutions, but the current feasible indoor positioning technology still has high material cost or limited positioning scope. In order to facilitate people to find their destination quickly in large buildings, this paper presents a feasible alternative method for indoor positioning and navigation. The method is based on mobile devices such as smart phones with built-in accelerometers. The application of this navigation method mainly includes the following steps: 1. A three-dimensional nodal arc network model representing the internal structure and layout of a building is constructed as a spatial reference for location and navigation. The network includes the spatial position information of the point element and the line element, the attribute information and the topological relation between the points and line elements. 2. Based on the shortest path algorithm, the user input the current position as the starting position of navigation, the target position as the terminal position of navigation and the path restriction condition to adjust the impedance value of the path, so as to obtain the initial shortest path; 3. When the user travels according to the navigation information, the displacement of the user is calculated based on the principle of the pedometer, and the current position of the user is calculated according to the coordinates of the displacement and the initial position of the section and displayed on the road map in real time. Through the above steps, the method realizes the real-time tracking of the user's position in the indoor environment and provides the navigation information to the user in good time. In order to verify the feasibility and effectiveness of this semi-automatic indoor positioning and navigation method, a Android mobile phone application for indoor navigation is designed and implemented in this paper. Taking the data of the main building of the college as an example, the three-dimensional network model of the main building is constructed, and the information of the self-defined positioning point is stored and obtained by combining the two-dimensional code coding technology and the recognition technology, and then the above methods are applied. Navigation from the current position to the target position is implemented inside the building. The experimental results show that the proposed method is simple and feasible, and the navigation path is accurate and the navigation information is easy to understand.
