摘要: Techniques are described for generating a texture using a plurality of images and a geometry corresponding to an object. The geometry is mapped to each of the plurality of images. A graph includes a plurality of nodes corresponding to portions of the images. An edge exists between a first node and a second node if a first portion corresponding to the first node and a second portion corresponding to the second node can be neighboring portions in a resulting image. Ways of forming the resulting image are represented by paths in the graph. 1-dges and nodes in the graph may have associated costs. A path in the graph having a smallest total cost is determined and represents the resulting image. A texture is generated for the object using the resulting image.

摘要: Images provide rich information regarding what they depict. For example, an image may have additional information, such as depth and/or 3D location values, for some points within the image. It may be advantageous to extrapolate the values from the valued points to the entire image because a new view of the image may be generated based upon values of points. Accordingly, an interpolated image may be generated by interpolating values for unvalued points based upon values of valued points. In particular, a set of valued points having desired cost paths may be determined for an unvalued point. A model may be applied to the set of valued points to interpolate a value for the unvalued point. One or more interpolated images may be projected onto a new view. In particular, points within an interpolated image may be projected onto locations within the new view based upon values of the points.

摘要: Embodiments of the present invention relate to systems, methods and computer storage media for associating a known geographic location with a known identity. Feature matching, of at least two images, is performed in at least two iterations. The iterations are based on an orientation of feature vectors associated with points of interest in each image. A geometric model is applied to the matched points of interest to improve the matched pairs. Two images are identified as being related. As a result, the known geographic location is associated with the known identity. Additional embodiments include augmenting feature vectors with a coordinate location of a related point of interest based on a geometric model. Further, an exemplary embodiment includes an additional matching iteration based on the augmented feature vectors. In an exemplary embodiment, the feature matching utilizes a Scale-Invariant Feature Transform (SIFT).

摘要: A measurement of an object from which data is collected may be determined. A scale of the object may be determined by determining the absolute or relative magnitude of the object in comparison to a magnitude of surrounding objects such as the total magnitude of the illustration. An appropriate container shape and size for the object may be determined by searching for a container size with a scale similar to the scale of the object. The object may be stored in a database with the appropriate container shape, size and the scale being attributes.

摘要: A method of using locational information for vehicles to determine the cost of traveling on transportation segments is disclosed. The transportation segment costs calculated may be used for many purposes such as providing the lowest cost travel path between two locations at a given time or in general. The cost also may be used to assign tolls and congestion pricing. In addition, the data may be used to determine when a certain vehicle has become less efficient and may require maintenance.

摘要: A semi-automatic map editor may allow a user to add features to a map with a minimum of effort. In one example, a user may add a road to a map by indicating where the endpoints of the road are. A system may then attempt to fill in the path of the road using the user-provided endpoints, an analysis of an aerial or satellite photograph, existing maps that show the road, or any other appropriate information. Using this information, the system may display a proposed path for the road between the endpoints that the user has indicated. The user may then fine tune and/or confirm the proposed path, thereby adding the road to the map. In addition to roads, other feature such as bodies of water, ski trails, etc., may be added in this manner.

摘要: Aggregated data associated with a geographic area may be obtained. The aggregated data may be dynamically distilled to obtain a presentation set of data based on a dynamically changing geographic location associated with the geographic area. A transmission of a stream of personalized audio data that is based on the presentation set of data may be initiated, via a device processor, to a receiving device associated with a user that is associated with the dynamically changing geographic location.

摘要: In one example, images may be used to create a model of a three-dimensional space, and the three-dimensional space may be annotated and/or edited. When a three-dimensional model of a space has been created, a user may associate various items with points in the three-dimensional space. For example, the user may create a note or a hyperlink, and may associate the note or hyperlink with a specific point in the space. Additionally, a user may experiment with the space by adding images to, or deleting images from, the space. Annotating and editing the space, rather than the underlying images, allows annotations and edits to be associated with the underlying objects depicted in the images, rather than with the images themselves.

摘要: Amalgamated maps, comprising interior maps overlaid on venues indicated in general maps can be automatically generated. Initially, interior maps can be obtained through targeted network searches, whose search results can be filtered to retain those that are most likely useable interior maps. A bounding polygon is generated for both interior map and venue exterior from general map. Subsequently, directional histograms representing orientations of lines in bounding polygons are generated and compared to automatically identify a rotation to align the interior map with the venue exterior from the general map. Anchor points are identified to locally deform the interior map, preserving internal structures, to better align with the venue exterior. Once aligned, the interior map can be combined with the general map, forming an amalgamated map. Updated geocoding can be performed based on locations of establishments in the venue as indicated by the interior map.
