Realization And Compensation Optimization Of Tracking System Based On Internet Of Things

With the continuous development of Internet of Things, more and more sensor detection equipments step into people's vision, some sensors can monitor the temperature and humidity of the environment; some sensors can detect long-range mobile targets; some sensors can see the real-time image of the real world. The information acquired is limited if a sensor is used alone, but people can complete a very complex monitor and detection requirement when a variety of sensors work together. This thesis researches and implements a multi-sensor linkage system based on Internet of Things technology above mentioned, as well as this thesis innovatively makes some improvements on tracking inaccurate problems generated in the linkage system.This thesis focuses on the research and implementation of the multi-sensor linkage system by using the traditional Internet of Things technology. And on this basis, the technology of data access platform is utilized to replace the gateway access in order to unify the access of sensors'data. Because data access platform can isolate the difference of underlying data protocol, and has a horizontal extension function; Meanwhile this thesis explores how to use the data distribution architecture to solve a large number of video data transmission problems among photoelectric sensors,which specifically uses the Java -Applet technology for the transmission of video data between the sensor and the client. The method of coordinate transformation in data fusion is first time used to solve the problem of inconsistency in multi-sensor coordinate system and error result from the installation position difference. The temporal alignment algorithm is first time used to calculate the time delay of multi-sensor cooperative linkage process. And the spacial alignment algorithm is first time used to solve the problem of tracking compensation in multi - sensor cooperative system.This system uses a loosely coupled module design to make it can carry most sensors detection system, has a certain universality.At last,we implemented a multi-sensor linkage system designed in the thesis, as well as verified the usability and tracking accuracy of the system through field test and simulation.
