Indoor Positioning Data Obstacle Avoidance and Visualization Framework Based on A* Algorithm

Currently the research on the map visualization and GIS visualization is relatively mature. But in the indoor environment, Indoor positioning system requires monitoring the location which is on vector map of positioning data and display positioning data trajectory. At the same time, Indoor positioning environment is complex, and has many obstacles such as walls. The connection between two positioning data point which are in the trajectory of positioning data always pass through the obstacles. To solve this problem, in this paper, we combine A* map routing algorithm and vector map visualization technology to propose a Obstacle Avoidance And Visualization Method of indoor positioning data trajectory which is on the vector map. And we introduce an indoor positioning data Obstacle Avoidance And Visualization Framework based on the method. The implementation of the framework is also discussed.
