Abstract: The invention discloses an indoor three-dimensional visible light fingerprint positioning method based on a multi-layer perceptron and a system thereof. The system comprises an LED light emitting modulator, an LED light receiving and photoelectric conversion module, a filter demodulator and a multi-layer perceptron positioning module which are connected in turn. Wherein, the LED light emitting modulator adopts a CDMA modulation mode; the LED light receiving and photoelectric conversion module receives the LED light source and converts the LED light source into an electric signal. The filter demodulator filters the electric signal and obtains the ID information of each LED through demodulation. The multi-layer perceptron positioning module uses ID information of the LED to predict the position of the device. The invention applies the multi-layer perceptron technology to indoor three-dimensional positioning, improves the accuracy of indoor positioning, has strong anti-interference ability and stability, and has broad application prospects.
