摘要
针对室内复杂环境和室内照明节点拓扑结构对可见光定位精度的影响,基于近似完美三角点测试(APIT)算法设计了一种多LED照明节点的可见光室内定位方法。该方法利用信号传输时间作为节点间距大小的判断凭证,结合APIT定位算法,实现室内可见光定位。仿真结果表明:该定位方法的定位误差在0.24 m左右浮动,在保证了定位精度的基础上,精简了定位设备成本,并提升了定位算法的计算效率,使得定位系统在实际场景中的应用更具稳定性与适用性。
Aiming at the influence of indoor complex environment and indoor lighting node topology on visible light positioning accuracy,a visible light indoor positioning method for multi-LED lighting nodes is designed based on the approximate perfect triangle point test(APIT)algorithm.The method uses the signal transmission time as the judgment voucher of the node spacing size,and combines the APIT positioning algorithm to realize indoor visible light localization.The simulation results show that the positioning error of the positioning method fluctuates around 0.24 m.On the basis of ensuring the positioning accuracy,the layout cost of the positioning device is simplified and the computational efficiency of the positioning algorithm is improved at the same time.The above aspects of improvement make the application of the system more stable and applicable in practical scenarios.
