Dual-modal indoor positioning method and device based on whale algorithm

Abstract

The present disclosure relates to a dual-modal indoor positioning method, device, electronic device and storage medium based on the whale algorithm. Wherein, the method includes: acquiring first modal connection information of the user based on the first modal connection and judging the user's first probability area; searching for a preset number of optimal second modal emission points including the first probability area Obtain the second modal connection information of the user based on the second modal connection, and determine the second probability area of ​​the user; adjust the reference signal strength value of the second modal emission point based on the whale algorithm, and predict the user's movement position. When the predicted user motion position vector is consistent with the user motion position vector, the positioning of the user position is completed. The present disclosure realizes the determination of the indoor position of the user through dual modes, and the fitting of the user's motion position based on the whale algorithm, and realizes the fast and accurate indoor position positioning of the user with less equipment.

Description

technical field [0001] The present disclosure relates to the field of indoor positioning, and in particular, to a dual-modal 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 the indoor environment. In a hospital, even if there are floor maps and guide signs, most of the time in seeing a doctor is still wasted on finding departments. In the parking lot, there are also many people who can't find a parking space and wander around. Under the increasingly urgent demand, indoor positioning has attracted great 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, family separation prevention, crowd monitoring and analysis, intelligent 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
