Research of Indoor Visible Light Positioning Based on Barometric Pressure Sensor

可见光通信定位技术是利用白光LED同时实现照明和通信的新型通信技术,为室内定位技术提供了新的可能.针对目前室内光通信定位方法过于复杂、计算量大的问题,基于接收信号强度定位技术,提出一种结合MS5611高精度气压传感器室内定位的方法,该方法引入室内高度差因素.通过MS5611高精度气压传感器测得接收端与发射端的高度差,利用LED朗博传输模型既可得到接收端的定位坐标,该方法具有计算量小,易于在单片机系统上实现等特点.

Visible light communieation technology is a new communieation technology which uses white LED to realize lighting and communieation, it provides new possibilities for indoor location. As the indoor visible light positioning is too complex and large calculation, a high precision indoor location way is proposed, it is combined with high accurate sensors of MS5611,and it is also consider the height ditterenee taetor. Through the measure of MS5611 barometrie pressure sensor to obtain the height ditterenee of IRX and TX end, and the location coordinate is obtained by use of LED lambertian model, The method has advantages of small computation amount, and easy to inlplement in MCU system.
