  • Point-cloud clip filter
    Patent number: 8456471
    Abstract: A viewer renders a first image from a point cloud of data of a scanned scene accessed from a data store. A region of interest may then be defined. In response, the image is updated to only include data included within the region of interest. Alternatively, the region of interest may be provided to a second viewer, where a second image is rendered or updated to only include data included within the region of interest.
    Type: Grant

  • Smart picking in 3D point clouds
    Patent number: 8396284
    Abstract: An embodiment of the invention includes a method for identifying a point representing a feature in a 3D dataset. The method includes performing a pick, which includes filtering the dataset to extract a subset of points based on certain criteria including a seed point and evaluating a metric for each point in the subset of points. The metric is a non-normalized probability that the point being evaluated represents the feature. The point or points with the highest metric is identified as representing the feature. Another embodiment of the invention includes a computer-readable medium comprising computer-executable instructions for identifying a point representing a feature in a 3D dataset. Another embodiment of the invention includes a method for displaying a view of a feature in a 3D dataset.
