    Abstract: A method for providing just-in-time access to data for calibrating an augmented reality (AR) device relative to an operation environment and then using the calibration data to register virtual content generated by the AR device with a scene being viewed by a user in the operation environment. An AR device is calibrated by pairing marker identifiers of 2-D markers affixed to objects in a physical environment with 3-D locations of those objects specified in a virtual environment containing 3-D model of those objects and then a marker-to-model location pairing list is generated. The pairing list is used to align displayed virtual 3-D content with an object appearing in the visualized physical environment. A location correction is computed at run-time based on a current AR device-to-marker offset computed from an image of the 2-D marker and the 3-D location of the object retrieved from the pairing list.

    Abstract: A system for monitoring processes includes a first compute node and a second compute node. The first compute node includes a process monitor, a status data analyzer, a process monitor checker, and a peer monitor. The process monitor is configured to generate process status data for a first instance of a software application. The status data analyzer is configured to selectively restart the first instance of the software application based on determining that an expected process of the first instance of the software application has stopped running. The process monitor checker is configured to restart the process monitor in response to determining that the process monitor has stopped running. The peer monitor is configured to, in response to determining that a second instance of the software application failed at the second compute node, perform an action based on incomplete tasks associated with the second instance of the software application.

    Abstract: Systems and methods for measuring the distance to a target object and acquiring three-dimensional coordinates, scale information, and point-to-point distance information for that target object in an environment using a remotely operated cable-suspended platform. The system uses on-board sensors and processing techniques to provide discrete or continuous measurements of the distances between points on a target object or the scale of the target object. The addition of on-board three-dimensional measurement capabilities to cable-suspended platforms enables these systems to acquire three-dimensional position data defined in the coordinate system of the environment, determine distances between objects or between points on the same object. The system can also be used to determine the scale factors of items in images captured by a camera carried by the cable-suspended platform, in the course of performing metrology-related tasks.

    Abstract: A tracking-enabled extended-reach tool system acting upon a workpiece. The tool system includes a gimbal positioned adjacent an opening in a surface, a sensor system, a computer control, and a display. The extended-reach arm has a first end, a second end, an end effector including a tool adjacent the first end. The extended-reach arm engages the gimbal for relative rotational movement and relative slidable movement through the opening positioning the end effector and the tool on a side of the surface opposite the second end. The sensor system is configured to measure a linear position of the extended-reach arm relative to the gimbal. The computer control receives signals from the sensor system indicative of the linear position of the extended-reach arm relative to the gimbal. The display is connected to the computer control and displays a representation of the workpiece and the tool relative to each other in real time.

    Abstract: A ground-based visual-inspection system includes a ground-based visual-inspection apparatus and a control system. The ground-based visual-inspection apparatus includes a mobile base, an actuatable arm coupled to the mobile base, and an effector coupled to the actuatable arm. The actuatable arm is locatable in a three dimensional space. The end effector includes a camera configured to capture images of a structure, such as an aircraft. The control system is configured to determine location information of the camera relative to a reference location and associate the location information with the images.
