AI Technical Summary

Problems solved by technology

However, emitters / sensors require regular maintenance and calibration, thus incurring maintenance costs
In addition, after long-term use of the transmitter / sensor, the signal will be attenuated, resulting in a decrease in positioning accuracy
On the other hand, the traditional indoor positioning technology needs to communicate with the user's mobile device. However, because the signal processing function of each mobile device is different, and the signal strength is not the same, it may cause recognition errors and reduce accuracy.

Abstract

A localization method includes the steps of: capturing a current image by a mobile device; transferring the current image to a remote end; performing image recognition on the current image according to a stored model trained by machine learning at the remote end, the model being generated beforehand by machine learning according to environmental images and corresponding labels, thereby obtaining acorresponding recognized label that includes localization information; and transferring the recognized label to the mobile device.

Description

technical field [0001] The present invention relates to an indoor positioning system and method, in particular to a positioning system and method for image recognition based on machine learning. Background technique [0002] Mobile devices (such as smart phones) generally use a global (satellite) positioning system (global positioning system, GPS) for positioning. However, positioning by the global (satellite) positioning system is not possible because satellite signals cannot be received in indoor spaces. [0003] The current indoor positioning technology is to install many transmitters and / or sensors indoors for indoor positioning. However, emitters / sensors require regular maintenance and calibration, thus incurring maintenance costs. In addition, long-term use of the transmitter / sensor will cause signal attenuation, resulting in a decrease in positioning accuracy. On the other hand, the traditional indoor positioning technology needs to communicate with the mobile devi...
