Abstract

The invention relates to a positioning calibration system, method and storage medium, including a movable platform and background processing equipment; the movable platform includes a movable device and a data processing device; the calibration module includes at least two different types of positioning sensors, the positioning sensor It is used to obtain the original calibration information of the movable platform in real time; the data processing device is used to obtain the wireless positioning information of the movable platform in real time and obtain the original calibration information; both the wireless positioning information and the original calibration information include the position coordinates of the movable platform and the corresponding Timestamp; the background processing equipment includes a storage module and a positioning trajectory demonstration module; the storage module is used to store the original calibration information and the wireless positioning information; the positioning trajectory demonstration module is used to generate a mobile platform based on the original calibration information and wireless positioning information. Dynamic tracks on the map. The above-mentioned positioning calibration system is applicable to a wide range of calibration environments of positioning measurement systems.

Description

technical field [0001] The present invention relates to the field of positioning technology, in particular to a positioning calibration method, system and storage medium. Background technique [0002] High-precision positioning service is a key support service in emerging information industries such as Internet of Vehicles, Internet of Things, and Industrial Internet. For example, driverless cars, vehicle management, location information query, intelligent handling robots, location friends, navigation, etc. In the future, there will be a large number of intelligent network terminals that need real-time and reliable precise positioning to realize their functions. [0003] In open outdoor areas, satellite navigation systems represented by GPS and Beidou and their enhancement technologies provide accurate and pervasive navigation and positioning services. However, in indoor and urban environments, the performance of satellite navigation systems is significantly degraded due to...
