|Abstract:||A new VLC-based indoor positioning method is proposed, which using four or more LED lamps and a mobile phone connected with a 4*4 photodiode array. The photodiode array is used to receive the three-dimensional coordinates of the LED lamps by means of visible light communication (VLC) and acquire the light spots of the LED lamps, and the front camera of the mobile phone is used to acquire the high resolution image of the LED lamps. The information from the photodiode array and the front camera can be matched using Kuhn-Munkres algorithm. An improved collinearity equation model is proposed to build the mapping relationship between the three-dimensional coordinates of the LED lamps and the image information acquired by the front camera. The mobile phone’s three-dimensional coordinates are calculated using the principle of photogrammetry. Moreover, a hardware-in-loop simulation experiment has been conducted and analyzed. The positioning method is proved to be valid and its positioning accuracy is up to decimeter level.
