    Abstract: Apparatus and methods for measuring a position of a point on a submerged surface. The apparatus includes: a platform; a liquid-tight pressure vessel fixedly coupled to the platform, wherein the liquid-tight pressure vessel is formed in part by an optically transparent enclosure; a pan-tilt mechanism coupled to the platform and disposed inside the liquid-tight pressure vessel; a camera mounted to the pan-tilt mechanism; a laser range meter affixed to the camera; and a refractive index sensor coupled to and disposed outside the liquid-tight pressure vessel. In accordance with one proposed implementation, the optically transparent enclosure is spherical, the pan-tilt mechanism has a pan axis and a tilt axis that intersect at a center of the optically transparent enclosure, and the laser range meter is located to emit a laser beam that is perpendicular to the optically transparent enclosure.

    Abstract: Systems and methods for supplying an open interface (e.g., web pages) for viewpoint navigation control of a three-dimensional (3-D) visualization of an object that is simple to create and fast and easy to use. This viewpoint navigation control application allows users to control the viewpoint in a 3-D environment by interacting with (e.g., clicking on) a 2-D hyperlink layout within a web browser (or other 2-D viewer with hyperlink capability). Position and orientation data for a selected viewpoint are transferred as part of a command message sent to the 3-D visualization application through an application programming interface when users select a hyperlink from a web page displayed by the 2-D layout application. The 3-D visualization application then retrieves data and displays a view of at least a portion of the 3-D model of the object with the predefined viewpoint specified in the command message.

    Abstract: Systems and methods for synchronized display of visualizations of three-dimensional (3-D) models and video images of aircraft for use in assembly of an aircraft. A video display process is configured to process the video image data so that the video images will have a user-selected viewpoint when displayed. In one embodiment, the user selects a virtual view direction and a smaller field-of-view from a full 360-degree field-of-view. A client request process is configured to construct and transmit a command data string containing encoded data specifying parameter values of the viewpoint representation formatted for 3-D model visualization. A server response process is configured to receive and decode the command data string into the specified parameter values representing the user-selected viewpoint for three-dimensional model visualization. A 3-D model visualization process is configured to process the 3-D model data so that 3-D model visualizations will have the user-selected viewpoint when displayed.

    Abstract: Systems and methods for high-speed non-destructive inspection of a half- or full-barrel-shaped workpiece, such as a barrel-shaped section of an aircraft fuselage. Such workpieces can be scanned externally using a mobile (e.g., translating) arch gantry system comprising a translatable arch frame disposed outside the fuselage section, a carriage that can travel along a curved track carried by the arch frame, a radially inward-extending telescopic arm having a proximal end fixedly coupled to the carriage, and an NDI sensor unit coupled to a distal end of the telescoping arm. The stiffeners of the fuselage sections can be scanned using a mobile scanner platform disposed inside the fuselage section, which platform comprises a radially outward-extending telescopic arm rotatably coupled to a mobile (e.g., holonomic or linear motion) platform and an NDI sensor unit coupled to a distal end of the telescoping arm. The scan data is matched with position data acquired using any one of a plurality of tracking systems to enable the display of NDI features/flaws on a three-dimensional representation of the workpiece.

    Abstract: A multi-configuration massive model system. The system comprises a processor unit and a comparator configured to run on the processor unit, a memory, and a configuration manager. The comparator compares sets of parts for two or more configurations of a vehicle to form a list comprising a group of common parts and a group of unique parts. The memory is configured to store a massive model dataset of the configurations of the vehicle with a list of the group of common parts and the group of unique parts for the configurations of the vehicle. The configuration manager, configured to run on the processor unit, receives input of a selected configuration and performs an action relating to the vehicle using the massive model dataset for the selected configuration of the vehicle with the list of the group of common parts and the groups of unique parts stored in the memory.
