Abstract: Provided are a method and apparatus for determining a positioning parameter, a computer device and a storage medium. The method includes: determining Time of Flight (ToF) spectrum data of a positioning signal according to the positioning signal sent via multi-channels by a terminal to be positioned; correcting an ideal spatial manifold matrix according to a preset antenna array deviation function, so as to obtain a corrected spatial manifold matrix; and determining a positioning parameter of Line Of Sight (LOS) of the positioning signal according to the ToF spectrum data and the corrected spatial manifold matrix, wherein the LOS is the shortest path from the terminal to be positioned to the antenna array.

Abstract: Provided are a positioning calibration system and method, and a storage medium. The positioning calibration system includes a movable platform (100) and a background processing device (200). The movable platform (100) includes a movable apparatus (110), and a positioning component (120) and a data processing apparatus (130); the positioning module (120) includes at least two different types of positioning sensors (121); the data processing apparatus (130) is configured to acquire wireless positioning information of the movable platform (100) in real time and acquire the original calibration information; the wireless positioning information and the original calibration information both include a position coordinate of the movable platform (100) with a corresponding time stamp when the position coordinate is acquired; the background processing device (200) includes a storage module (210) and a positioning trajectory demonstration module (220).
