Research of indoor location technology based on wireless sensors and video
To increase the indoor location tracking accuracy and extend the location area, the fusion model for location tracking based on wireless sensors and video is constructed. By analyzing the location characteristic of wireless sensors and video, fusion location strategy based on particle filer is defined, which improve the capacity of video detection targets and compensate the location accuracy and blind area ofwireless sensors. Methods of evaluating importance weights of particles based on wireless sensors and video observation model is put forward, which improve the efficiency of particle updating. Simulation analysis demonstrated the feasibility of the model and the effectiveness of the algorithm.
