Electronic device localization based on imagery

An electronic device (102) includes one or more imaging cameras (118). After a reset (502) of the device or other specified event, the electronic device identifies an estimate of the device's pose based on location data (504) such as Global Positioning System (GPS) data, cellular tower triangulation data, wireless network address location data, and the like. The one or more imaging cameras may be used to capture imagery of the local environment of the electronic device, and this imagery is used to refine the estimated pose to identify a refined pose of the electronic device (514). The refined pose may be used to identify additional imagery information, such as environmental features, that can be used to enhance the location based functionality of the electronic device. 种电子设备[102]包括个或多个成像相机[118]。在设备的重置[502]或其他指定事件之后，电子设备基于诸如全球定位系统[GPS]数据、蜂窝塔三角测量数据、无线网络地址位置数据等的位置数据来识别设备的姿态的估计[504]。个或多个成像相机可以用于捕捉电子设备的本地环境的影像，且该影像被用于改善估计的姿态以识别电子设备的改善的姿态[514]。改善的姿态可被用于识别附加的影像信息，诸如环境特征，其可以被用来增强电子设备的基于位置的功能。
