【Abstract】 In order to improve the performance of indoor visible light localization system, an indoor visible light fingerprint localization method based on Genetic Algorithm-Convolutional Neural Network(GACNN) training is proposed. The algorithm introduces a one-dimensional convolutional neural network learning model, uses the genetic algorithm to train the convolutional neural network according to the hyperparameter setting of the convolutional neural network, binars the hyperparameters and then uses the elite genetic algorithm to train the CNN to solve the process of relying on experience and fuzzy optimization of the parameter adjustment of the convolutional neural network model. The experiment results show that in the indoor positioning scenario of 4 m×4 m×2.5 m, the positioning accuracy of the average positioning error of 4.1 cm can be obtained by using the proposed positioning algorithm. Through simulation experiments, compared with the convolutional neural network positioning algorithm, the average positioning error is reduced by 25%. The performance of different indoor visible light positioning algorithms is compared and analyzed, and the technical advantages of this algorithm are verified.更多还原
