【摘要】 室内定位技术作为室外定位技术的延展,近年来室内定位技术用处愈加明显。设计了一套应用于室内的可见光定位系统,采用广角镜头的摄像头作为传感器,摄像头对空间顶部的光信息进行采集并处理,采用STC15F2K60S2单片机作为传感器及测量电路的处理器,采用msp430单片机作为LED控制电路的处理器,通过传感器自身的坐标和灯光信息的数据拟合准确得到自身位置。实验结果表明:通过采用广角摄像头作为传感器来定位,系统结构更简单,可以使室内定位应用更加广泛。更多还原

【Abstract】 Indoor positioning technology is the development of the outdoor positioning technology, recently, indoor positioning technology is used frequently. The purpose of this paper is to design a practical visible light positioning system for indoor, the system uses wide angle lens camera as a sensor to collect and process the optical information from the top of space, the system uses STC15 F2 K60 S2 Single-chip Microcomputer as the processor of the sensor and the measurement circuit, msp430 Single-chip Microcomputer as the processor of the LED circuit and the information transfer circuit, the system uses the coordinate of the sensor and the data of visible light to get its location accurately by fitting, the results show that the advantages of using wide angle camera as the sensor to design indoor positioning of visible light system is simpler system construction and it can make indoor positioning application wider.更多还原
