摘要： Methods, systems, and computer program products are provided for determining camera parameters and three dimensional locations of features from a plurality of images of a geographic area. These include, detecting features in the plurality of images where each of the images cover at least a portion of the geographic area, comparing the detected features between respective ones of the images to determine a plurality of matched features, selecting a subset of the plurality of matched features, and determining the camera parameters and the three dimensional positions of one or more of the detected features using the selected subset. The respective matched features are selected depending on a quantity of other matched features in proximity to the respective matched features.

摘要： Methods and systems for generating data objects for multi-resolution geometry in a three-dimensional model are provided. A region of high resolution geometry in the three-dimensional model having a level of detail that is higher than a level of detail associated with geometry data surrounding the region of high resolution geometry can be identified. A boundary of the region of high resolution geometry can be extended and high resolution geometry can be generated within the extended boundary. The high resolution geometry can be spatially partitioned into a plurality of geospatial data objects according to a hierarchical spatial partitioning scheme. The geospatial data objects can be selectively stored in a memory. For instance, geospatial data objects associated with the extended boundary can be identified and excluded from a hierarchical tree data structure storing geometry data associated with the three-dimensional model.

摘要： Systems, methods, and computer storage mediums are provided for filling missing data in a spatially distributed, graphically represented data set. An example method includes dividing the data set into a first plurality of tiles along a first plurality of boundary lines. For each of the first plurality of tiles, a first set of fill data is generated to fill missing data in the data set. Then, for each of a determined number of dimensions of the tiles, the data set is divided into a new plurality of tiles along a new plurality of boundary lines offset from the last immediately determined plurality of boundary lines and a new set of fill data is generated to fill the missing data. A portion of the new set of fill data includes a portion of the last immediately generated set of fill data that fall along the boundary of the respective new tile.
