Abstract
(EN) Embodiments of the present invention provide a positioning processing method, a positioning processing apparatus, and a movable platform. The positioning processing method comprises: acquiring first indication information, and determining a working state of a first antenna according to the first indication information; and when it is determined that the first antenna is in a first state, controlling to establish a connection between a positioning module and a second antenna, so that the positioning module receives a signal transmitted by the second antenna. In view of the above, the embodiments of the present invention provide a positioning processing method based on multiple antennas. A positioning strategy can be switched depending on an antenna state, thereby better ensuring the precision of positioning for the movable platform in various environments.
(FR) L'invention concerne, selon des modes de réalisation, un procédé de traitement de positionnement, un appareil de traitement de positionnement et une plateforme mobile. Le procédé de traitement de positionnement comprend : l'acquisition de premières informations d'indication, et la détermination d'un état de fonctionnement d'une première antenne en fonction des premières informations d'indication ; et lorsqu'il est déterminé que la première antenne est dans un premier état, la commande de l'établissement d'une connexion entre un module de positionnement et une seconde antenne, de sorte que le module de positionnement reçoive un signal émis par la seconde antenne. Compte tenu de ce qui précède, les modes de réalisation de la présente invention concernent un procédé de traitement de positionnement basé sur de multiples antennes. Une stratégie de positionnement peut être commutée en fonction d'un état d'antenne, ce qui permet de mieux garantir la précision de positionnement pour la plateforme mobile dans divers environnements.
(ZH) 本发明实施例提供一种定位处理方法、定位处理装置及可移动平台。其中,定位处理方法包括:获取第一指示信息,并根据第一指示信息确定第一天线的工作状态,当判定第一天线处于第一状态时,控制建立定位模块与第二天线的连接,使得定位模块接收第二天线传输的信号。可见,本发明实施例提供了一种基于多天线的定位处理方法,可以根据天线状态切换定位策略,进而较好地保证可移动平台在各种环境下的定位精度。
