A computer implemented method of creating a dental model for use in dental articulation includes providing a first set of digital data corresponding to an upper arch image of at least a portion of an upper dental arch of a patient, providing a second set of digital data corresponding to a lower arch image of at least a portion of a lower dental arch of the patient, and providing hinge axis data representative of the spatial orientation of at least one of the upper and lower dental arches relative to a condylar axis of the patient. A reference hinge axis is created relative to the upper and lower arch images based on the hinge axis data. Further, the method may include bite alignment data for use in aligning the lower and upper arch images. Yet further, the method may include providing data associated with condyle geometry of the patient, so as to provide limitations on the movement of at least the lower arch image when the arch images are displayed. Further, a wobbling technique may be used to determine an occlusal position of the lower and upper dental arches. Various computer implemented methods of dental articulation are also described. For example, such dental articulation methods may include moving at least one of the upper and lower arch images to simulate relative movement of one of the upper and lower dental arches of the patient, may include displaying another image with the upper and lower dental arches of the dental articulation model, and/or may include playing back recorded motion of a patient's mandible using the dental articulation model.

A computer research tool for indexing, searching and displaying data is disclosed. Specifically, a computer research tool for performing computerized research of data including textual objects in a database or a network and for providing a user interface that significantly enhances data presentation is described. Textual objects and other data in a database or network is indexed by creating a numerical representation of the data. The indexing technique called proximity indexing generates a quick-reference of the relations, patterns and similarity found among the data in the database. Proximity indexing indexes the data by using statistical techniques and empirically developed algorithms. Using this proximity index, an efficient search for pools of data having a particular relation, pattern or characteristic can be effectuated. The Computer Search program, called the Computer Search Program for Data represented in Matrices (CSPDM), provides efficient computer search methods. The CSPDM rank orders data in accordance with the data's relationship to time, a paradigm datum, or any similar reference. An alternative embodiment of the invention employs a cluster link generation algorithm which uses links and nodes to index and search a database or network. The algorithm searches for direct and indirect links to a search node and retrieves the nodes which are most closely related to the search node. The user interface program, called the Graphical User Interface (GUI), provides a user friendly method of interacting with the CSPDM program and prepares and presents a visual graphical display. The graphical display provides the user with a two or three dimensional spatial orientation of the data.

A method and system for determining orientation and positioning of a vehicle trailer. A digital camera is placed on a vehicle. The camera is pointed to a trailer attached to the vehicle. The camera acquires images of the trailer. These images are processed and spatial positioning and orientation of the trailer is determined based on image processing. A special marker visible by the camera is set on the trailer. Relative positions of devices attached to the vehicle—global positioning receiver, spatial orientation measuring device and the digital camera are measured. When each digital frame is formed, coordinates and orientation data of the camera are measured. Pixels corresponding to the marker in the image are determined. A simplified copy of the image, containing only the data related to the marker pixels, is generated. The marker pixels are used for calculating position and azimuth orientation of the marker. The azimuth orientation of the trailer is calculated based on calculated azimuth orientation of the marker.

A system and a corresponding method for determining a spatial relationship between a surface having a predetermined pattern and an apparatus are disclosed. A portion of the surface may be imaged and compared with the predetermined pattern. The comparison produces at least one reference measurement that may be used to determine a spatial relationship expressed in at least parameters that define an orientation of the surface. By using knowledge of the predetermined pattern together with an algebraic model of the image formation by the apparatus, a numerical adaptation can be performed. Parameters obtained from the adaptation can then be used to calculate the spatial relationship between the apparatus and the surface in terms of, for example, a distance between the apparatus and the surface or an angle between the surface and an axis extending through the apparatus.
