Abstract

A system and method for augmenting a GNSS/INS system by using a vision system is provided. The GNSS system generates GNSS location information and the INS system generates inertial location information. The vision system further generates vision system location information including horizon, plumb lines and distance travelled. The GNSS information, INS information and vision system are combined in a Kalman filter to produce improved location information.

Abstract

A system and method for navigating a collection of toolbar items that are displayed on an electronic display screen. The toolbar items, such as buttons, are organized into an ordered set of toolbar pages. Each toolbar page contains a fixed number of toolbar items. One toolbar page from the set is displayed at a time in a fixed display area, e.g., a tile, on the display screen. User input causes the currently displayed toolbar page to be replaced by another toolbar page in the ordered set. The user input, such as a continuous swipe gesture across the toolbar display tile, determines the direction of navigation through pages in the ordered set and the speed of the page navigation. The toolbar display area can show the position of the currently displayed toolbar in the ordered set and animated transitions between toolbar items may be displayed to signal toolbar page replacements. A user input, such as a tap of a finger, can select the replacement toolbar.

Abstract

A system and method for automatically controlling working edges on a heavy equipment vehicle is provided. A GNSS/INS system determines a location of the vehicle. A vision system calculates a location of the working edge in a vision system coordinate system by obtaining images of a target connected to the working edge using a camera with a fixed field view that incorporates the relative movement of the target and determining the relative position of the target in the images. The location is then transformed to the navigation system coordinate system. The transformed location information is used by a working edge control system to control the placement of the working edge.

Abstract

A system determines an otherwise unknown position and orientation of a camera in a working environment, relative to an associated coordinate system, based on visually identifiable unique objects in images taken by the camera. The system utilizes a database that includes or may be updated to include position coordinates for unique objects of interest. The system identifies a plurality of objects within one or more images taken by the camera at a given location, and enters the database either to determine position coordinates for the respective identified objects or to add position coordinates to the data base for the respective identified objects, or both. The system may also update the database to include newly identified unique objects and objects that are altered between images, to determine position and orientation of the camera in a changing environment. Sensors may be included to add additional information relative to the position and orientation of the camera.

The invention relates to a method and system for determining the position (23) of a hand-held power tool (1) on a wall (22). The method comprises measuring distances (11) within a plane (9) perpendicular to a tooling axis (8) in at least two directions, comprising at least the direction to one side wall and the direction to the floor or the ceiling. At least one non-contact measurement sensor module (3) measures distances (11) in a multitude of angles in an angular range of at least 1° around the at least two directions. From the distance sequence (11) measured by the at least one measurement sensor module (3) a calculation and storing unit (4) automatically calculates a function (11'), wherein extrema, particularly minima (11a'-11d'), represent shortest distances (11a-11d) to walls, floor and/or ceiling adjacent to the wall (22). From said function (11') the calculation and storing unit (4) deduces the shortest distances (11a-11d), and output means, in particular a display unit (18) and/or acoustical output means, provide information about the shortest distances (11a-11d) so as to allow positioning relative to the shortest distances (11a-11d).

Abstract

A method improves surface scanning measure machine speed while minimizing tip touchdown impact on the surface of the object being measured. Specifically, the method controls a surface scanning measuring machine having a probe head with a distal probe tip that contacts the surface of an object to be measured. To that end, the method selects a nominal initial contact point (on the surface) having a normal vector, and then moves the distal probe tip toward the nominal initial contact point along an approach path. The approach path has a generally linear portion that generally linearly extends from the nominal initial contact point to some non-contacting point spaced from the surface. The generally linear portion forms an angle of between about 20 degrees and about 60 degrees with the normal vector.

Abstract

A 3-D view manipulation apparatus surrounds a 3-D model displayed on a display device, and allows a user to manipulate the view of the model by manipulating the apparatus, without having to divert the user's view from the model. The apparatus is transparent or semi-transparent, such that all of its surfaces are simultaneously visible. The apparatus may include control features on its surface, edges, or corners to facilitate changing the view of the model to a vantage point from or through that control feature. The apparatus may include a set of orthogonal axes at its center, about which the model may be made to rotate.

Abstract

Methods and apparatus are provided that improve graphical software applications, by filtering the data for display according to techniques for defining and manipulating visual indicia. Data may be filtered according to multiple filters that are combined in a number of ways to form the set of data for display. Data may be filtered onto logically and geometrically according to their relationships with other data. Visual indicia that represent filters may be drag-and-dropped between input areas to facilitate ease of use. Data selected according to a filter may be displayed at the same time as non-selected data by applying visually distinctive characteristics to the selected data. A virtual environment may be shown simultaneously on several different video displays at a single workstation.

Abstract

A method for maintaining consistency between objects in a computer system by defining relationship patterns. A relationship pattern is a collection of entities having relationships with a common entity called an active entity. A semantic entity is associated with the active entity describing the actions to be performed for updating one or more entities of the relationship pattern in response to modification, copying, or deletion of one or more entities participating in the relationship pattern.
