3D model updates using crowdsourced video

摘要

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.

主权项

1. A computer-implemented method, comprising:
obtaining, using one or more computing devices, video data comprised of a plurality of images depicting a location, the video data including positioning data representing a visual orientation and position of each image with respect to the location; identifying, by the one or more computing devices, data representing a 3D geometry of objects associated with the location; comparing, by the one or more computing devices, visual features of objects depicted in one or more corresponding areas between images from the video data and image projections of the 3D geometry; and updating, by the one or more computing devices, the data representing the 3D geometry based at least in part on the comparison by integrating images from the video data into the 3D geometry.
