摘要： A method of acquiring a three-dimensional surface image of an object using a range camera automatically calculates an optimal number of scans. The optimal number of scans is calculated in accordance with operator-defined and camera optical parameters. Scan data acquired for each scan is merged with a preference for higher resolution data over lower resolution data for any given scanned area, such that the merged scan data forms the three-dimensional surface image of the object.

摘要： An x-ray imaging device includes a borescope and an x-ray detector positioned at a distal end of the borescope. The x-ray detector can be configured to be movable into and out of an optical path and can include a scintillation screen. The movably configured x-ray detector can be moved into the optical path, when x-rays are impinging, and out of the optical path, when a visible image of a test object is desired, facilitating navigation of the x-ray detector through a test object. The x-ray imaging device can include an imager, for converting an image to an electronic format. The imager can be positioned at the proximal end of the borescope, with the borescope including a waveguide, for guiding light to a proximal end thereof. Alternatively, the imager can be positioned between the distal end of the borescope and the x-ray detector.

摘要： A part marking technique based on a string of alphanumeric human-readable characters which are “printed” using a “texture” which is “cut-out” from a two-dimensional redundant bit pattern, e.g., a two-dimensional matrix of data cells selectively occupied or not occupied by dots or other suitable geometric shapes. The bit pattern is readable by a system comprising an imager and a computer for processing the data contained in the acquired image. In the case of a bit pattern formed by visible dots, the system comprises an optical detector, e.g., a television camera or other imager. The part marking is simultaneously readable by a human and a computer system.

摘要： A durable part marking is achieved by local surface material modification. Selected surface area properties of the part are altered without substantial alteration of the physical configuration of the part. The alterations are placed in a coherent pattern accomplishing a durable method of identification marking on a part. Subsequently, the coherent pattern is detected and the coherent pattern interpreted to retrieve the original identification marking. Unlike labeling, ink marking, stamping or etching, many surface or near-surface modifications are not necessarily visible to the human eye. Hence, the invention includes: 1) a method for surface modification, 2) a method for assuring enhanced readability and accuracy of the read back of the encoded data, and 3) a method for locating the surface alteration.

摘要： The present invention is a system for real time tracking of position and orientation, termed "pose", of a remote camera. While remote cameras have been used on a regular basis to inspect machinery for wear or damage, knowing the exact location of a camera is difficult. Off-line feature extraction is employed with on-line pose determination. The feature extraction precomputes features from a CAD model of the object visible in a selected set of views. The on-line pose determination starts from an initial pose estimate, determines the visible model features, projects them into a two-dimensional image coordinate system, matches each to the current camera image, and uses the differences between the predicted and matched feature positions in a gradient descent technique to iteratively refine the pose estimate. The on-line portion of the system is designed to execute at video frame rates, providing a continual indication of borescope tip pose.

摘要： An Optical Probe Measurement Device accurately and efficiently measures locations of visible features of a structure without making contact with the structure. It employs a centering microscope which a user looks through to locate the feature to be measured. The centering microscope is connected to an orientation plate in a known pose which has targets measurable with a 3D measurement device. The 3D measurement device determines 3D locations of the targets. A light source is attached to the orientation plate to produce a light beam which intersects the optical axis at the focal point of the centering microscope, being a distance D.sub.0 away from the end of the centering microscope. When this light beam impinges on the surface of the structure at the same location as the feature seen in the centering microscope, the feature is exactly the D.sub.0 away from the centering microscope. A calculation device receives the measured 3D locations of the targets, the pose of the centering microscope relative to the orientation plate, and the distance D.sub.0, and calculates the actual 3D location of the focal point, also being the location of the feature on the structure. Optionally a triggering device may be used to indicate when to calculate the location of the focal point.
