Problems solved by technology

However, based on the traditional geometric measurement method and scene perception method, the accuracy is limited. Second, due to the accuracy and computational complexity, generally only two-dimensional positioning can be realized. If the indoor three-dimensional positioning is to be realized, more complex algorithms and Add hardware

Abstract

The invention relates to the field of indoor positioning, and provides an indoor visible light positioning method based on machine learning. The method comprises the following steps of acquiring a training set that includes at least one set of training data, wherein the set of training data includes a channel estimation matrix parameter set and position information of a receiver corresponding to the channel estimation matrix parameter set, and the channel estimation matrix parameter set includes channel estimation matrix parameters of at least three light sources defining a unit area; calculating the corresponding channel estimation matrix parameter set received by the receiver to be located, and inputting the channel estimation matrix parameter set into a machine learning model trained bythe training set; and outputting the position information of the receiver to be located. Since the channel estimation matrix of each light source is used as a parameter, and the machine learning model is combined, the calculation accuracy is improved.

Description

technical field [0001] The present application relates to the field of positioning, and in particular to a machine learning-based indoor visible light positioning method and device. Background technique [0002] In today's world, with the continuous development of economy and modern technology, people's indoor activity space is becoming larger and more complex, and the demand for navigation and positioning services is also increasing. Wireless technology is used for positioning and navigation to obtain people or objects. location information. A typical positioning technology is the Global Positioning System (GPS), which is widely used in many fields. It has the advantages of wide coverage, high positioning accuracy, complete functions and excellent performance. However, GPS signals cannot penetrate thick walls, coupled with the interference of various wireless electromagnetic wave signals indoors and the influence of multipath transmission effects, resulting in low position...
