摘　　要：提出了一种基于室内可见光定位技术的智能车导航方案。在可见光定位方面,通过快速傅里叶变换(FFT)、最小二乘法、Tolay迭代算法可获得误差在12 cm以下的空间坐标;在智能车导航方面,采用A算法,并通过可见光定位获取当前空间坐标来修正智能车导航路线,使导航误差在15 cm以下,达到更精准的导航。This paper proposes an intelligent car navigation solution based on indoor visible light positioning technology.In terms of visible light positioning,spatial coordinates with errors below 12 cm can be obtained through fast Fourier transform(FFT),least squares method and Tolay iteration algorithm.As for intelligent car navigation,the A algorithm is adopted,and the current spatial coordinates are obtained through visible light positioning to correct the navigation route of the intelligent car,achieving navigation accuracy of below 15 cm for more precise navigation.
