Abstract: Systems and methods for identifying views for geographic imagery using geolocated text are provided. More specifically, a multi-resolution textual descriptors map associating text with specific geographic locations can be accessed and used to identify a viewpoint for displaying geographic imagery associated with an object of interest. The multi-resolution textual descriptors map can be a collection of data that associates text objects from the geolocated text with a plurality of varying zoom levels relative to the geographic area. The multi-resolution text map can provide labels of varying specificity based on the zoom level relative to the geographic area. Geographic locations and/or zoom levels corresponding to a text object describing or otherwise associated with the object of interest can be identified from the multi-resolution textual descriptors map. A view encompassing the identified geographic locations and/or zoom levels can be used to provide a viewpoint for the object of interest in the imagery.

Abstract translation: 提供了使用地理定位文本识别地理图像视图的系统和方法。 更具体地，可以访问将文本与特定地理位置相关联的多分辨率文本描述符图，并用于识别用于显示与感兴趣对象相关联的地理图像的视点。 多分辨率文本描述符图可以是将来自地理定位文本的文本对象与相对于地理区域的多个变化缩放级别相关联的数据的集合。 多分辨率文本图可以基于相对于地理区域的缩放级别提供不同特征的标签。 可以从多分辨率文本描述符图中识别对应于描述或者与感兴趣对象相关联的文本对象的地理位置和/或缩放级别。 包含所识别的地理位置和/或缩放级别的视图可用于为图像中的感兴趣对象提供视点。
