Abstract
(EN)
Disclosed are a location method and device, an aircraft and a computer-readable storage medium, the method comprising: determining a position deviation value between the center of a location module (124) on an aircraft (12) and the center of a load (123) on the aircraft (S201); acquiring an aircraft attitude (S202); according to the position deviation value and the aircraft attitude, determining a position compensation value of the load (123) (S203); and according to the position compensation value, determining actual position information of the load (123) (S204). In this way, automated and intelligent location is realized and location accuracy is improved.

L'invention concerne un procédé et un dispositif de localisation, un aéronef et un support d'informations lisible par ordinateur, le procédé consistant : à déterminer une valeur d'écart de position entre le centre d'un module de localisation (124) sur un aéronef (12) et le centre d'une charge (123) sur l'aéronef (S201); à acquérir une assiette d'aéronef (S202); en fonction de la valeur d'écart de position et de l'assiette d'aéronef, à déterminer une valeur de compensation de position de la charge (123) (S203); et en fonction de la valeur de compensation de position, à déterminer des informations de position réelle de la charge (123) (S204). Ainsi, une localisation automatisée et intelligente est réalisée et la précision de localisation est améliorée.
