In certain approaches, the model produced by the IGCS is built using data regarding the geometry, lighting, surfaces, and environment of the physical space. In certain approaches, the model produced by the IGCS is both photorealistic and fully modifiable.

Abstract: Techniques are disclosed for automated selection of navigation points for navigating through a computer-generated virtual environment such as, for example, a virtual reality (VR) environment. Specifically, an input set of connected navigation points in a virtual environment is automatically pruned to a connected subset thereof, according to one or more selection factors where at least one of the selection factors is whether the subset will continue to be “connected” after pruning a navigation point from the input set. In addition to whether the pruning of a navigation point will allow the remaining navigation points to remain connected, techniques for pruning based on one or more additional selection factors are also disclosed. According to one additional selection factor, navigation point pruning is based on the degree to which coverage of an input set of navigation points would be reduced by pruning any given navigation point from the input set.

Abstract: Techniques are provided for increasing the accuracy of automated classifications produced by a machine learning engine. Specifically, the classification produced by a machine learning engine for one photo-realistic image is adjusted based on the classifications produced by the machine learning engine for other photo-realistic images that correspond to the same portion of a 3D model that has been generated based on the photo-realistic images. Techniques are also provided for using the classifications of the photo-realistic images that were used to create a 3D model to automatically classify portions of the 3D model. The classifications assigned to the various portions of the 3D model in this manner may also be used as a factor for automatically segmenting the 3D model.

Abstract: The capture and alignment of multiple 3D scenes is disclosed. Three dimensional capture device data from different locations is received thereby allowing for different perspectives of 3D scenes. An algorithm uses the data to determine potential alignments between different 3D scenes via coordinate transformations. Potential alignments are evaluated for quality and subsequently aligned subject to the existence of sufficiently high relative or absolute quality. A global alignment of all or most of the input 3D scenes into a single coordinate frame may be achieved. The presentation of areas around a particular hole or holes takes place thereby allowing the user to capture the requisite 3D scene containing areas within the hole or holes as well as part of the surrounding area using, for example, the 3D capture device. The new 3D captured scene is aligned with existing 3D scenes and/or 3D composite scenes.
