Abstract

L'invention concerne un procédé de traitement d'informations, un véhicule aérien sans pilote et un support de stockage. Le procédé consiste à : obtenir des informations de qualité de signal d'une station de base, les informations de qualité de signal étant mesurées sur la base d'une connexion de communication avec la station de base pendant un processus de vol d'un véhicule aérien sans pilote ; obtenir des informations de position du véhicule aérien sans pilote lors de la mesure des informations de qualité de signal ; et déterminer des informations de distribution de qualité de signal en fonction des informations de qualité de signal et des informations de position. Selon la présente invention, les informations de distribution de qualité de signal sont déterminées en fonction des informations de qualité de signal et des informations de position, et les informations de distribution de qualité de signal peuvent être utilisées pour guider la connexion de communication avec la station de base pendant le processus de vol du véhicule aérien sans pilote, ce qui permet d'améliorer la qualité de communication entre le véhicule aérien sans pilote et la station de base.
