A 10-Foot media user interface is herein described. A computer user interface may be designed for primary use as a 10-Foot user interface, where a user controls the computer using a remote control device, instead of as a traditional 2-Foot user interface where the user controls the computer using keyboard and mouse from directly in from of the computer. The 10-Foot user interface uses 3D space and animations to more clearly indicate navigation and selection of items in the user interface to the controlling user. Use of three-dimensional space also increases the display screen real estate that is available for content items, and allows the media user interface to move unselected items out of primary view of the user. The user interface may animate movement in three-dimensions to allow the user to more easily conceptually follow navigation of the user interface.

Systems and methods for 2D image and spatial data capture for 3D stereo imaging are disclosed. The system utilizes a cinematography camera and at least one reference or “witness” camera spaced apart from the cinematography camera at a distance much greater that the interocular separation to capture 2D images over an overlapping volume associated with a scene having one or more objects. The captured image date is post-processed to create a depth map, and a point cloud is created form the depth map. The robustness of the depth map and the point cloud allows for dual virtual cameras to be placed substantially arbitrarily in the resulting virtual 3D space, which greatly simplifies the addition of computer-generated graphics, animation and other special effects in cinemagraphic post-processing.

A system and method for the imaging management of a 3D space where various substantially real-time scan images have been acquired is presented. In exemplary embodiments according to the present invention, a user can visualize images of a portion of a body or object obtained from a substantially real-time scanner not just as 2D images, but as positionally and orientationally located slices within a particular 3D space. In such exemplary embodiments a user can convert such slices into volumes whenever needed, and can process the images or volumes using known image processing and / or volume rendering techniques.

In exemplary embodiments according to the present invention, a user can manage various substantially real-time images obtained, either as slices or volumes, and can control their visualization, processing and display, as well as their registration and fusion with other images, volumes and virtual objects obtained or derived from prior scans of the body or object of interest using various modalities.

This invention provides a system and method for determining the three-dimensional alignment of a modeledobject or scene. After calibration, a 3D (stereo) sensor system views the object to derive a runtime 3D representation of the scene containing the object. Rectified images from each stereo head are preprocessed to enhance their edge features. A stereo matching process is then performed on at least two (a pair) of the rectified preprocessed images at a time by locating a predetermined feature on a first image and then locating the same feature in the other image. 3D points are computed for each pair of cameras to derive a 3D point cloud. The 3D point cloud is generated by transforming the 3D points of each camera pair into the world 3D space from the world calibration. The amount of 3D data from the point cloud is reduced by extracting higher-level geometric shapes (HLGS), such as line segments. Found HLGS from runtime are corresponded to HLGS on the model to produce candidate 3D poses. A coarse scoring process prunes the number of poses. The remaining candidate poses are then subjected to a further more-refined scoring process. These surviving candidate poses are then verified by, for example, fitting found 3D or 2D points of the candidate poses to a larger set of corresponding three-dimensional or two-dimensional model points, whereby the closest match is the best refined three-dimensional pose.

Techniques and tools are described for rendering views of a map in which map metadata elements are layered in 3D space through which a viewer navigates. Layering of metadata elements such as text labels in 3D space facilitates parallax and smooth motion effects for zoom-in, zoom-out and scrolling operations during map navigation. A computing device can determine a viewer position that is associated with a view altitude in 3D space, then render for display a map view based upon the viewer position and metadata elements layered at different metadata altitudes in 3D space. For example, the computing device places text labels in 3D space above features associated with the respective labels, at the metadata altitudes indicated for the respective labels. The computing device creates a map view from points of the placed labels and points of a surface layer of the map that are visible from the viewer position.

A 3D image processing apparatus first generates a combined view volume that contains view volumes set respectively by a plurality of real cameras, based on a single temporary camera placed in a virtual 3D space. Then, this apparatus performs skewing transformation on the combined view volume so as to acquire view volumes for each of the plurality of real cameras. Finally, two view volumes acquired for the each of the plurality of real cameras are projected on a projection plane so as to produce 2D images having parallax. Using the temporary camera alone, the 2D images serving as base points for a parallax image can be produced by acquiring the view volumes for the each of the plurality of real cameras. As a result, a processing for actually placing the real cameras can be skipped, so that a high-speed processing as a whole can be realized.

The invention provides inter alia methods and apparatus for determining the pose, e.g., position along x-, y- and z-axes, pitch, roll and yaw (or one or more characteristics of that pose) of an object in three dimensions by triangulation of data gleaned from multiple images of the object. Thus, for example, in one aspect, the invention provides a method for 3D machine vision in which, during a calibration step, multiple cameras disposed to acquire images of the object from different respective viewpoints are calibrated to discern a mapping function that identifies rays in 3D space emanating from each respective camera's lens that correspond to pixel locations in that camera's field of view. In a training step, functionality associated with the cameras is trained to recognize expected patterns in images to be acquired of the object. A runtime step triangulates locations in 3D space of one or more of those patterns from pixel-wise positions of those patterns in images of the object and from the mappings discerned during calibration step.

A method that enables creation of a 3D virtual reality environment from a series of 2D images of a scene. Embodiments map 2D images onto a sphere to create a composite spherical image, divide the composite image into regions, and add depth information to the regions. Depth information may be generated by mapping regions onto flat or curved surfaces, and positioning these surfaces in 3D space. Some embodiments enable inserting, removing, or extending objects in the scene, adding or modifying depth information as needed. The final composite image and depth information are projected back onto one or more spheres, and then projected onto left and right eye image planes to form a 3D stereoscopic image for a viewer of the virtual reality environment. Embodiments enable 3D images to be generated dynamically for the viewer in response to changes in the viewer's position and orientation in the virtual reality environment.

A dynamic version may be used for estimating moving sensors locations in a real-time environment. The method may use dynamic distance measurement updates among sensors, and utilizes subproblem solving for static sensor localization. Methods to deploy sensor localization algorithms in clustered distributed environments are also provided, permitting application to arbitrarily large networks. In addition, the methods may be used to solve sensor localizations in 2D or 3D space. A preprocessor may be used for localization of networks without absolute position information.

Interactive three-dimensional (3D) virtual tours are generated from ordinary two-dimensional (2D) still images such as photographs. Two or more 2D images are combined to form a 3D scene, which defines a relationship among the 2D images in 3D space. 3D pipes connect the 2D images with one another according to defined spatial relationships and for guiding virtual camera movement from one image to the next. A user can then take a 3D virtual tour by traversing images within the 3D scene, for example by moving from one image to another, either in response to user input or automatically. In various embodiments, some or all of the 2D images can be selectively distorted to enhance the 3D effect, and thereby reinforce the impression that the user is moving within a 3D space. Transitions from one image to the next can take place automatically without requiring explicit user interaction.

The disclosed terrain model is a generative, probabilistic approach to modeling terrain that exploits the 3D spatial structure inherent in outdoor domains and an array of noisy but abundant sensor data to simultaneously estimate ground height, vegetation height and classify obstacles and other areas of interest, even in dense non-penetrable vegetation. Joint inference of ground height, class height and class identity over the whole model results in more accurate estimation of each quantity. Vertical spatial constraints are imposed on voxels within a column via a hidden semi-Markov model. Horizontal spatial constraints are enforced on neighboring columns of voxels via two interacting Markov random fields and a latent variable. Because of the rules governing abstracts, this abstract should not be used to construe the claims.

This invention provides a system and method to propagate uncertainty information in a deep learning pipeline. It allows for the propagation of uncertainty information from one deep learning model to the next by fusing model uncertainty with the original imagery dataset. This approach results in a deep learning architecture where the output of the system contains not only the prediction, but also the model uncertainty information associated with that prediction. The embodiments herein improve upon existing deep learning-based models (CADe models) by providing the model with uncertainty / confidence information associated with (e.g. CADe) decisions. This uncertainty information can be employed in various ways, including (a) transmitting uncertainty from a first stage (or subsystem) of the machine learning system into a next (second) stage (or the next subsystem), and (b) providing uncertainty information to the end user in a manner that characterizes the uncertainty of the overall machine learning model.
