Bimodal indoor positioning method and device based on whale algorithm

Abstract

The invention relates to a bimodal indoor positioning method and device based on a whale algorithm, electronic equipment and a storage medium. The method comprises the steps: acquiring first modal connection information of a user based on first modal connection, and judging a first probability area of the user; searching a preset number of optimal second modal emission points containing the first probability region; acquiring second modal connection information of the user based on second modal connection, and judging a second probability area of the user; adjusting the reference signal intensity value of the second modal emission point based on the whale algorithm, and pre-judging and fitting the motion position of the user; and when the pre-judged user motion position vector is consistent with the user motion position vector, completing positioning of the user position. According to the invention, the indoor position of the user is determined through double modes, the user motion position fitting based on the whale algorithm is realized, and the indoor position of the user can be quickly and accurately positioned by using less equipment.

Description

technical field [0001] The present disclosure relates to the field of indoor positioning, and in particular, relates to a dual-mode indoor positioning method, device, electronic device and computer-readable storage medium based on a whale algorithm. Background technique [0002] Indoor positioning, as the name suggests, is to achieve positioning in an indoor environment. In a hospital, even if there are floor maps and guidance signs, most of the time when seeing a doctor will still be wasted looking for departments. In the parking lot, there are many people who can't find a parking space and wander around. Under the increasingly urgent demand, indoor positioning has attracted a lot of attention in recent years. Indoor positioning has a wide range of applications, such as shopping guides in shopping malls, reverse car search in parking lots, anti-scattering family members, crowd monitoring and analysis, smart manufacturing, emergency rescue, and personnel asset management. ...

Problems solved by technology

However, due to the influence of multipath effects, the indoor environment is variable and complex, and there is no universal solution; therefore, how to improve accuracy, real-time performance, security, improve scalability, and reduce costs is still a research hotspot, making people no matter In the living or working environment, you can obtain location information anytime and anywhere, and enjoy the convenience brought by location-based services

[0004] Most of the existing technologies use a single-mode wireless signal transmission source to locate the user's indoor location. Since the commonly used wireless signal transmission sources cannot take into account the requirements of accuracy and breadth, in order to achieve accurate positioning indoors, it is necessary to arrange a large number of wireless signals. Signal transmission source, high cost

At the same time, in the existing technology, the positioning of the user through the signal strength value requires the user to connect to a large number of high-precision wireless signal transmission sources at the same time, which will inevitably lead to a decrease in the immediacy of positioning
