    • Aspects of the invention pertain to matching a selected image/photograph against a database of reference images (324) having location information. The image of interest may include some location information itself, such as latitude/longitude coordinates and orientation. However, the location information provided by a user's device (308, 310, 312) may be inaccurate or incomplete. The image of interest is provided to a front end server (502), which selects one or more cells (452, 454, 456) to match the image against. Each cell may have multiple images and an index. One or more cell match servers (504) compare the image against specific cells based on information provided by the front end server. An index storage server (506) maintains index data for the cells and provides them to the cell match servers. If a match is found, the front end server identifies the correct location and orientation of the received image, and may correct errors in an estimated location of the user device.
    • 本发明的方面涉及将所选择的图像/照片与具有位置信息的参考图像(324)的数据库进行匹配。 感兴趣的图像可以包括一些位置信息本身,例如纬度/经度坐标和方向。 然而,由用户设备(308,310,312)提供的位置信息可能不准确或不完整。 感兴趣的图像被提供给前端服务器(502),前端服务器选择一个或多个单元(452,454,456)以匹配图像。 每个单元可以具有多个图像和索引。 一个或多个小区匹配服务器(504)基于由前端服务器提供的信息来比较图像与特定小区。 索引存储服务器(506)维护小区的索引数据并将其提供给小区匹配服务器。 如果找到匹配,则前端服务器识别接收到的图像的正确位置和方向,并且可以校正用户设备的估计位置中的错误。
