Abstract: In one aspect, a system and method is provided that matches images that are associated with street addresses with images that are associated with locations that are stored with respect to another reference system, such as latitude/longitude. If the images match, the street address is associated with the location. In a further aspect, text contained in the images is extracted and associated with the street address as well.

Abstract translation: 在一个方面，提供了一种系统和方法，其将与街道地址相关联的图像与与相对于另一参考系统（例如纬度/经度）存储的位置相关联的图像进行匹配。 如果图像匹配，街道地址与该位置相关联。 在另一方面，图像中包含的文本也被提取并与街道地址相关联。

Abstract: Initial trajectory data that provides an initial description of an approximate trajectory of a device during a time period, and correction data that indicates a location of the device outside the approximate trajectory of the device within the time period, are received. A modified trajectory data that provides a modified description of a corrected trajectory of the device is generated. In particular, terms to express (i) location constraints that limit deformation of the approximate trajectory of the device and (ii) a modification constraint that limits departure of the corrected trajectory of the device from the location indicated by the correction data are generated, and the initial description of the approximate trajectory of the device is modified using the generated terms.
