Abstract
(EN) A positioning method and apparatus, an electronic device (900, 1900), a storage medium (904, 1932), and a computer program product. The positioning method comprises: obtaining at least one positioning signal and an environmental image of an environment where the electronic device (900, 1900) is located (S21); performing signal positioning according to the at least one positioning signal to obtain first position information of the electronic device (900, 1900) (S22); according to a positioning network corresponding to the first position information and the first position information, determining at least one target preset image matching the environmental image (S23); and performing visual positioning by means of the positioning network according to the environmental image and the at least one target preset image to obtain second position information of the electronic device (900, 1900) (S24).
(FR) La présente invention concerne un procédé et un appareil de positionnement, un dispositif électronique (900, 1900), un support de stockage (904, 1932) et un produit de programme informatique. Le procédé de positionnement comprend les étapes consistant à : obtenir au moins un signal de positionnement et une image d'environnement d'un environnement où le dispositif électronique (900, 1900) est situé (S21) ; effectuer un positionnement de signal en fonction du ou des signaux de positionnement pour obtenir des premières informations de position du dispositif électronique (900, 1900) (S22) ; en fonction d'un réseau de positionnement correspondant aux premières informations de position et des premières informations de position, déterminer au moins une image prédéfinie cible correspondant à l'image d'environnement (S23) ; et effectuer un positionnement visuel au moyen du réseau de positionnement en fonction de l'image d'environnement et de l'image prédéfinie cible ou des images prédéfinies cibles pour obtenir des secondes informations de position du dispositif électronique (900, 1900) (S24).
(ZH) 一种定位方法、装置、电子设备(900,1900)、存储介质(904,1932)及计算机程序产品，定位方法包括：获取电子设备(900,1900)所处环境的至少一个定位信号及环境图像(S21)；根据至少一个定位信号进行信号定位，得到电子设备(900,1900)的第一位置信息(S22)；根据第一位置信息对应的定位网络及第一位置信息，确定与环境图像相匹配的至少一个目标预置图像(S23)；根据环境图像及至少一个目标预置图像，通过定位网络进行视觉定位，得到电子设备(900,1900)的第二位置信息(S24)。
