Labeling for Three-Dimensional Occluded Shapes

摘要

Systems and methods for displaying labels in conjunction with geographic imagery provided, for instance, by a geographic information system, such as a mapping service or a virtual globe application are provided. Candidate positions for displaying labels in conjunction with geographic imagery can be determined based at least in part on a virtual camera viewpoint. The candidate positions can be associated with non-occluded points on three-dimensional models corresponding to the labels. Adjusted positions for labels can be determined form the plurality of candidate positions. The labels can be provided for display in conjunction with the geographic imagery at the adjusted positions.

1. A method of displaying imagery of a geographic area, comprising:
receiving, by one or more computing devices, data indicative of a request to view geographic imagery of a geographic area from a virtual camera viewpoint; accessing, by the one or more computing devices, a label for each of two or more points of interest, each label associated with an initial position in the geographic imagery; identifying, by the one or more computing devices, a plurality of candidate positions for each label based at least in part on the virtual camera viewpoint, each of the plurality of candidate positions associated with a non-occluded point on a three-dimensional model corresponding to a geographic location of the point of interest associated with the label; determining, by the one or more computing devices, an adjusted position for each label from the plurality of candidate positions; and providing for display, by the one or more computing devices, each label at the adjusted position in the geographic imagery from the virtual camera viewpoint.
