Abstract

The invention discloses an indoor positioning and navigation method combined with voice recognition, and relates to the technical field of indoor positioning. Including: adopting the method of converting the sound signal collected by the device terminal into a position signal, and at the same time correcting and marking the basic positioning results, and using deep learning algorithms to assist in training basic positioning and correcting abnormal positioning areas, specifically including the following steps: (1) Extract the position signal from the sound signal; (2) Judge the validity of the position signal; (3) Use the position signal to correct and mark the basic positioning results; (4) Use the deep learning algorithm to analyze the basic positioning results Offline data is used for training and applied to the basic positioning in the later stage. The method of the present invention can not only correct the basic positioning, but also mark and train the offline data of the basic positioning, so as to improve the accuracy of the basic positioning when there is no sound information.

Description

technical field [0001] The invention relates to the technical field of indoor positioning, in particular to an indoor positioning and navigation method combined with voice recognition. Background technique [0002] With the advancement and development of network technology, positioning technology based on indoor spatial signals has also received more and more attention. Indoor spatial signals generally include, for example, WiFi, Bluetooth, BLE, geomagnetism, barometer, and the like. The principle of indoor positioning is to generate a spatial fingerprint based on the distribution of the above signals in the whole space, match the spatial signal of the user's current location, find the position with the greatest similarity, and realize the positioning capability. But in the actual process, as the environment changes, the spatial signal will change. The local positioning accuracy will decrease. The cost of re-acquisition of spatial signals is relatively high, and it is dif...
