Abstract

The invention discloses a positioning method and apparatus based on ultrasonic waves, and a computer readable storage medium. The method includes: determining time differences for receiving ultrasonicsignals broadcasted by beacons when a mobile terminal receives the ultrasonic signals sent by the beacons; determining differences of distances from the beacons to the mobile terminal according to the time differences; and determining the position of the mobile terminal according to the distance differences and position coordinates of the beacons. According to the scheme, a plurality of beacons in different positions are arranged indoors, the differences of the distances from different beacons to the mobile terminal are determined according to the time differences for receiving the ultrasonicwaves broadcasted by the beacons in different positions, the position of the mobile terminal is determined according to the distance differences and the position coordinates of the ultrasonic waves,the positioning of the mobile terminal by a plurality of ultrasonic information points is realized through reception of the ultrasonic signals sent by the beacons in different positions, and the positioning is more accurate.

Description

technical field [0001] The present invention relates to the field of ultrasonic technology, in particular to an ultrasonic-based positioning method, device and computer-readable storage medium. Background technique [0002] With the development of science and technology, the public has higher and higher requirements for positioning and navigation, especially in complex indoor environments, such as supermarkets, underground garages, airports, exhibition halls and other places, it is often necessary to determine the location information of mobile terminals or their holders . Although there are various positioning methods for outdoor environments, the indoor environment is different from the outdoor environment. The indoor environment is complex and the positioning accuracy is poor. The positioning methods for the outdoor environment are not suitable for indoor positioning, and indoor positioning is difficult. Contents of the invention [0003] The main purpose of the presen...
