摘要:
The aspects described herein include receiving a request for available images depicting a user. One or more time and location indicators indicating one or more locations visited by the user are determined. Based on at least in part the one or more time and location indicators, a set of candidate images may be identified. The set of candidate images depict one or more locations at a time corresponding to at least one of the time indicators. Pose data related to the user may be obtained based on the location indicators. The pose data indicates a position and orientation of the user during a visit at a given location depicted in the set of candidate images. One or more images from the set of candidate images may be selected based on the pose data and the 3D reconstruction. The selected images include at least a partial view of the user.

Aspects of the disclosure relate to generating a sequence of images or other visual representations associated with an entity, otherwise known as a semantic image navigation experience. After an entity is selected, a set of sub-entities may be identified. Each sub-entity in the set has a containment relationship with the selected entity as well as at least one associated landmark and one associated pre-stored navigation experience. Then, a ranking order of the sub-entities in the set may be determined based on characteristics of each entity. Based on the determined ranking order, a subset of sub-entities may be selected. A semantic image navigation experience for the selected entity may then be generated using the pre-stored navigation experiences associated with the subset of sub-entities.

Systems and methods for aligning ground based images of a geographic area taken from a perspective at or near ground level and a set of aerial images taken from, for instance, an oblique perspective, are provided. More specifically, candidate aerial imagery can be identified for alignment with the ground based image. Geometric data associated with the ground based image can be obtained and used to warp the ground based image to a perspective associated with the candidate aerial imagery. One or more feature matches between the warped image and the candidate aerial imagery can then be identified using a feature matching technique. The matched features can be used to align the ground based image with the candidate aerial imagery.
摘要:
A system and method is provided for determining whether images of a geographic location identify features with characteristics consistent with shadows cast by people, and using such determination to annotate map information. If such features are identified at the location, the map may be annotated to indicate that the location is frequented by pedestrians.

Systems, methods, and computer storage mediums are provided for creating a scene scan from a group of photographic images. An exemplary method includes determining a set of common features for at least one pair of photographic images. The features include a portion of an object captured in each of a first and a second photographic image included in the pair. The first and second photographic images may be captured from different optical centers. A similarity transform for the at least one pair of photographic images is the determined. The similarity transform is provided in order to render the scene scan from each pair of photographic images. At least one of the rotation factor, the scaling factor, or the translation factor associated with the similarity transform is used to position each pair of photographic images such that the set of common features between a pair of, at least in part, align.

Systems and methods for navigating an imagery graph are provided. In some aspects, a first image is provided for display, where the first image corresponds to a first image node within an imagery graph, where the imagery graph comprises image nodes corresponding to images from a plurality of different imagery types, and where each image node in the imagery graph is associated with geospatial data. An indication of a selection of a predetermined region within the first image is received, where the predetermined region is associated with a position in the first image that corresponds to geospatial data associated a second image node within the imagery graph. A second image corresponding to the second image node is provided for display in response to the indication of the selection of the predetermined region.

An exemplary method includes prompting a user to capture video data at a location. The location is associated with navigation directions for the user. Information representing visual orientation and positioning information associated with the captured video data is received by one or more computing devices, and a stored data model representing a 3D geometry depicting objects associated with the location is accessed. Between corresponding images from the captured video data and projections of the 3D geometry, one or more candidate change regions are detected. Each candidate change region indicates an area of visual difference between the captured video data and projections. When it is detected that a count of the one or more candidate change regions is below a threshold, the stored model data is updated with at least part of the captured video data based on the visual orientation and positioning information associated with the captured video data.

An exemplary method for navigating among photos includes determining, using one or more computing devices, visual characteristics of a person depicted in a first image associated with a first location. These visual characteristics of the person are detected in a second image associated with a second location. Using the one or more computing devices, a series of intermediate images are identified based on the first location and the second location. Each intermediate image is associated with a location. The series of intermediate images and the second image are provided. Images of an intermediate destination from the series of intermediate images are selected based on a density of images at the intermediate destination. A 3D reconstruction of the intermediate destination is then generated based on the selected images. Thereafter, a visual presentation of images traversing through the 3D reconstruction of the intermediate destination to the second image is prepared for display.
