摘要
随着移动通信与无线网络等技术的发展,室内可见光定位技术越来越受到人们的关注。文章针对室内可见光定位原理,基于信号到达时间的距离的测量方法,给出了以STM32F103ZET6为核心处理器来实现室内可见光定位的设计方案,并对在80 cm×80 cm×80 cm定位空间内采用呈网格分布的多个点进行了测试,对于实测的平均定位误差为10 cm以内,验证了方案的可行性及有效性。
With the development of technologies such as mobile communication and wireless network, indoor visible light positioning technology has drawn more and more attention. In this paper, aiming at the principle of indoor visible light positioning and the method of measuring the distance based on the signal time of arrival, a design scheme of indoor visible light positioning based on STM32FI03ZET6 is given. In the space of 80 cm × 80 cm × 80 cm several points distributed in the grid are tested, and the average positioning error is less than 10 cm, which verified the feasibility and effectiveness of the scheme.
