AI Technical Summary

Technical Problem

In complex scenarios such as high-rise canyons, it is difficult for mobile devices to achieve precise positioning through the Global Satellite Navigation System (GNSS) and low-precision inertial measurement units (IMUs), which are affected by GNSS signal attenuation and IMU results cumulative errors.

Method used

The GNSS signal strength, number of star searches and carrier phase difference positioning results received by the mobile device determine the environment type, and use the ultra-wideband device to communicate with the ultra-wideband device on the vehicle to obtain position information and distance information, and calculate the mobile device with the triangular positioning method. location.

Benefits of technology

Implementing high-precision positioning of mobile devices in complex environments overcomes the problems of GNSS signal attenuation and IMU error, and improves positioning accuracy.

Abstract

The invention provides a mobile equipment positioning method and device, electronic equipment, a storage medium and a computer program product, and the method comprises the steps: according to the intensity of a global satellite navigation system signal received by the mobile equipment, the number of searched satellites of the mobile equipment, and a carrier phase difference positioning result of the mobile equipment, obtaining a carrier phase difference positioning result of the mobile equipment; the environment type of the mobile device is determined, position information sent by a second ultra wide band device arranged on a vehicle is received through a first ultra wide band device arranged on the mobile device according to the environment type of the mobile device, and the position information is used for indicating the position of the second ultra wide band device. Distance information is obtained, the distance information is used for indicating the distance between the first ultra-wideband device and the second ultra-wideband device, and the position of the mobile device is determined according to the position information and the distance information. According to the scheme, the position of the mobile equipment can be accurately calculated in a complex environment.
