Problems solved by technology

[0003] However, due to the complex indoor environment, the signal will encounter great interference during the propagation process, such as non-line-of-sight problems caused by signal reflection, refraction, and diffraction, which will lead to unstable signal strength. The positioning accuracy is low when the algorithm is used for positioning

Abstract

The embodiment of the invention provides an indoor location method and device, an electronic device and a storage medium. The method comprises the steps of: generating particles in a target scope; determining a target sighting distance signal with strongest signal strength from each received target signal; calculating an upper limit value and a lower limit value of a distance between a current position of a to-be-located object and a target transmission node; determining the generated particles located in the target region as reference particles; for each reference particle, calculating a theoretical signal strength for receiving the signal transmitted by each signal transmission node when the to-be-located object is located at the reference particle; scoring each reference particle; and,determining the position of the reference particle with highest score as the current position of the to-be-located object. By application of the method provided by the embodiment of the invention, thelocation precision is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless positioning, in particular to an indoor positioning method, device, electronic equipment and computer-readable storage medium. Background technique [0002] At present, location-based services are becoming more and more important in people's lives. The current indoor positioning technology can utilize signals such as WiFi and Bluetooth, and use an algorithm based on received signal strength RSSI (Received Signal Strength Indication, received signal strength indication) for positioning. [0003] However, due to the complex indoor environment, the signal will encounter great interference during the propagation process, such as non-line-of-sight problems caused by signal reflection, refraction, and diffraction, which will lead to unstable signal strength. When the algorithm is used for positioning, the positioning accuracy is low. Contents of the invention [0004] The purpose of the emb...
