摘要： A method for determining registration accuracy of an augmented reality system is provided. The method includes the steps of providing an input device for inputting a position of a user's touch; registering the input device with a workspace coordinate system of the augmented reality system; displaying a virtual object in a known position; recording a user's touch position in response to the user attempting to touch the virtual object; and calculating a registration error of the augmented reality system by comparing the user's touch position to the known position of the virtual object. The input device may be a passive device used in conjunction with a tracking system of the augmented reality system or an active device, such as a touch-sensitive device, coupled to the augmented reality system which outputs the user's touch position.

摘要： A system and method for calibrating a stereo optical see-through HMD (head-mounted display). A preferred method integrates measurement for an optical see-through HMD and a six degrees of freedom tracker that is fixedly attached to the HMD to perform calibration. Calibration is based on the alignment of a stereoscopically fused marker image, which is perceived in depth, with a single 3D reference point in a world coordinate system from various viewpoints. The user interaction to perform the calibration is extremely easy compared to conventional methods and does not require keeping the head static during the calibration process. In one aspect, a method for calibrating a stereo HMD comprises the steps of displaying a 2-dimensional marker image on each eye display of the stereo HMD for view by a user, wherein the 2-dimensional marker images are displayed with an offset so as to induce a 3-dimensional marker that is perceived by the user as being at a distance away from the user; aligning the 3-dimensional marker image with a preselected reference point; collecting calibration data associated with the alignment; and computing a model of the HMD using the collected calibration data.

摘要： Two adjacent objects with a gap between the objects rotate in a hot atmosphere with a temperature greater than 300 F in a gas turbine. Automatic and accurate contactless measurement of the gap is performed by taking images of the gap. An image, preferably an infra-red image is taken from the gap, a processor extracts the two edges from the image of the gap. The processor also determines a line through the pixels of an edge by applying a Hough transform on the pixels. The edges are substantially parallel. A line substantially perpendicular to the lines is also determined. Using the substantially parallel lines and the line substantially perpendicular to the substantially parallel lines the processor determines a width of the gap.

摘要： For pipeline inspection, a small, untethered capsule (a “piglet”) images from within a pipeline. The capsule is small enough that rotation about any of three orthogonal axes while within the pipeline is possible. Movement both along the pipeline and perpendicular to the longitudinal axis is possible. To assure images of the pipeline without viewing gaps, the field of view for imaging surrounds the capsule without a gap. Given the possible rotation and translation, the captured images may be motion compensated to provide oriented images of a length of the pipeline.

摘要： A rotating rotor in a turbine has blades attached. At least one blade is a reference blade of which a reference position is determined by a Once-Per-Rotation sensor. A camera positioned at a viewing port takes a sequence of images of all the blades during a rotation at a trigger moment determined by a controller. The controller receives a signal indicating that the reference blade passes its reference point. The controller is provided with data about the number of blades, the position of the camera and a desired dwell of an image related to the blade. The controller calculates the trigger moments and generates trigger signals to the camera. The trigger moment is adjusted for changing rotor speed by extracting a blade feature from blade images. The camera records images that are labeled and stored as image data on a storage device.

摘要： A detection method is based on a statistical analysis of the appearance of model patches from all possible viewpoints in the scene, and incorporates 3D geometry during both matching and pose estimation processes. By analyzing the computed probability distribution of the visibility of each patch from different viewpoints, a reliability measure for each patch is estimated. That reliability measure is useful for developing industrial augmented reality applications. Using the method, the pose of complex objects can be estimated efficiently given a single test image.

摘要： A method wherein images of different types of objects within a class are partitioned into region stacks. For each one of the stacks, the method: (a) applies a template to extract fragments having a predetermined size and one of a plurality of different spatial orientations, to generate extracted templates; (b) determines, from the extracted templates, a most frequent one thereof having only a first number of fragments with a common spatial orientations; (c) records the number of images having the determined most frequent extracted template; (d) repeats (b) and (c) with successively increasing number of fragments until the number of recoded images falls below a threshold; and (e) selects as a master extracted template the one of the most frequent templates having the largest recorded number of fragments. The master extracted templates for the stacks are combined into a map that is then compared with background images to remove extracted templates matching segment in the background.
