Image based location determination

Image based location determination is provided. For example, one or more computing devices 120, 130, 140 receive an image 510 of a location. The image is processed to identify one or more features 520, 530 in the image. The one or more computing devices may access pre-stored geometry data that identifies a plurality of features and associated locations. A matching location is determined by comparing the identified one or more features to the pre-stored geometry data. 提供了基于图像的位置确定。例如，一个或多个计算设备120、130、140接收位置的图像510。处理所述图像以识别所述图像中的一个或多个特征520、530。所述一个或多个计算设备可以访问识别多个特征以及相关联的位置的预存储的几何结构数据。通过将所识别的一个或多个特征与预存储的几何结构数据相比较，确定匹配位置。
