Methods, systems, and apparatus including medium-encoded computer program products for generating and visualizing 3D scenes include, in one aspect, a method including: obtaining site data acquired by one or more capture devices, wherein the site data comprises data sets corresponding to two or more locations about a physical site, and each respective data set comprises (i) imaging data of the physical site, (ii) coordinate data for the imaging data, and (iii) time metadata for the imaging data; reconstructing a series of three dimensional (3D) modeled scenes of the physical site from the site data using the imaging data, the coordinate data, and the time metadata; receiving a request having associated position, orientation and time data; and generating, in response to the request, output for display of a portion of the 3D modeled scenes to represent the physical site based on the position, orientation and time data.

Systems and methods for generating time discrete 3D scenes

Methods, systems, and apparatus, including medium-encoded computer program products, for generating and visualizing 3D scenes include, in one aspect, a method including: obtaining metadata for 2D images that are related to a location of interest; searching for discrete image correspondences between pairs of the 2D images; grouping the 2D images into different time periods, including inferring one or more time periods for a portion of the 2D images that do not have date metadata; receiving a selection of at least one of the different time periods; finding camera intrinsic and extrinsic parameters for each image grouped into the selected time period; reconstructing a 3D scene of the location during the selected time period from the 2D images grouped into the selected time period using the camera intrinsic and extrinsic parameters; and providing the 3D scene for use in displaying the location of interest from different 3D perspectives.

Systems and methods for generating 3D scenes with time element for display

A system, apparatus, method, computer program product, and computer readable storage medium provide the ability to reconstruct a surface mesh. Photo image data is obtained from a set of overlapping photographic images. Scan data is obtained from a scanner. A point cloud is generated from a combination of the photo image data and the scan data. An initial rough mesh is estimated from the point cloud data. The initial rough mesh is iteratively refined into a refined mesh.
