Abstract

The invention relates to a positioning calibration system and method and a storage medium. The positioning calibration system comprises a movable platform and background processing equipment, the movable platform comprises a movable device and a data processing device; the calibration module at least comprises two different types of positioning sensors, and the positioning sensors are used for acquiring original calibration information of the movable platform in real time; the data processing device is used for acquiring wireless positioning information of the movable platform in real time and acquiring original calibration information; the wireless positioning information and the original calibration information both comprise position coordinates of the movable platform and corresponding timestamps; the background processing device comprises a storage module and a positioning track demonstration module. The storage module is used for storing the original calibration information and the wireless positioning information; and the positioning track demonstration module is used for generating a dynamic track of the movable platform on the virtual map according to the original calibration information and the wireless positioning information. The positioning calibration system is wide in calibration environment application range for the positioning measurement system.

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...
