Abstract: A measurement process, intended for measuring at least one wheel of a train, including an acquisition step, during which a plurality of profiles of at least a part of the wheel are acquired by plurality of optical sensors, as the train moves in front of the optical sensors, a mapping step, during which, for each optical sensor, the profiles acquired by the optical sensor are joined by a control module, to obtain a map of the part of the wheel further transformed into a cloud of points, a rejoining step, during which the clouds of points obtained from the optical sensors are joined to form a three-dimensional image of the wheel, and an analysis step, during which a plurality of reference points and reference distances are measured on the three-dimensional image.

Abstract: Jitter is removed from point cloud data by processing different groups of data points in the point cloud data in succession to minimize the entropy of the point cloud data. Each group in the point cloud data is generated at either different points in time or from detecting different pulses of reflected laser light from a target. The data points in a selected group are repetitively shifted en masse in the coordinate system of the point cloud data and the entropy of the point cloud data is re-calculated until subsequent shifts of the data points in the selected group does not further reduce the entropy. The remaining groups are subsequently processed in a similar fashion until the entropy of the point cloud data reaches a minimum.

Abstract: An example automated locomotive spotting system includes a locomotive having a tractive effort mechanism for moving the locomotive along a track, and a locomotive controller configured to control the tractive effort mechanism to move the locomotive along the track. The locomotive controller includes an odometer configured to monitor a distance traversed by the locomotive along the track. The locomotive controller is configured to receive a requested spotting distance value, and initiate movement of the locomotive along the track via the tractive effort mechanism. The locomotive controller is also configured to monitor, by the odometer, the distance traversed by the locomotive along the track, and inhibit movement of the locomotive in response to the monitored odometer distance indicating the locomotive has traversed the requested spotting distance.

Abstract: Methods and systems for the absolute high-resolution measurement of angle of rotation of a shaft, which allow for concurrent measuring of axial displacement and/or encoded identification information, are disclosed. Included is a method for measuring characteristics of a rotating shaft comprising obtaining optical signals by optically probing one or more patterns having a leading edge and a series of symbols disposed at one or more circumferences of the shaft; oversampling the optical signals; measuring time of arrival for the leading edges and determining therefrom an amount of time between arrival of two or more of the leading edges; interpolating and extrapolating the amount of time between arrival of the leading edges; and determining therefrom one or more of shaft twist, angle of rotation and/or axial loading, translation, or displacement. The methods include optically probing a pattern disposed around the circumference of a shaft that comprises a series of wedge-shaped symbols.

Abstract: The present invention relates to an apparatus for acquiring data relative to a dimension of an elongated object defining a longitudinal axis and a first and a second end, the apparatus comprising: an imaging sensor device defining a field of view and an optical axis, the imaging sensor device being adapted to image the elongated object in the field of view; a transporting device adapted to position the elongated object in the field of view and to transport the elongated object in a transport direction substantially parallel to the longitudinal axis of the elongated object and forming an angle with the optical axis; an illuminating device adapted to emit electromagnetic radiation to illuminate the elongated object in the field of view; and an optical deflection system including an optical deflector which is adapted to be movable between a first operative position where it is located outside the field of view of the imaging sensor device and a second operative position where it is located within the field of view of the imaging sensor device, and which is adapted to deflect electromagnetic radiation travelling parallel to the longitudinal axis towards said imaging sensor device so as to obtain an image of the first or of the second end of the elongated object. The present invention also relates to a method for acquiring data relative to a dimension of an elongated object defining a longitudinal axis and having a first and a second end.

Abstract: An imprint pattern forming method includes contacting a template with a pattern in a front surface with an imprint material formed in a substrate to fill the imprint material into the pattern, curing the imprint material filled in the pattern to form an imprint material pattern, and after forming the imprint material pattern, separating the template from the imprint material pattern while applying pressure to the back surface of the template.

Abstract: A method and device for detection of rotated segments in a continuous multi-segment rod transferred in a machine used in tobacco industry. A signal of an error of the shape of said continuous multi-segment rod is generated, the rod including a plurality of segments arranged one after another in a common wrapping, in which the rod that is transferred in a direction along its axis is simultaneously scanned by optical sensors, the directions of scanning of the optical sensors being oriented at an angle other than 90° to each other. The rod diameter is measured by repeated scans such that the shortest segment of the rod is scanned at least once, the results of the scans being compared with a predetermined reference value, and each difference between the results of the scans and the predetermined value is converted into the signal of the error of shape.

Abstract: A system for orientating point cloud data of a first surface relative to base reference data of a structure includes an input source generator adapted to provide the point cloud data, a tilt-correction means for orientating the point cloud data relative to the base reference data, a data editing means to filter spurious point data from the point cloud data, and a volume measurement means to measure the volume of objects that are non-fixably connected to the surface to segment the non-fixably connected objects from the point cloud data. The first surface is the surface of a wear liner. After orientation of the point cloud data with the base reference data, the surface displacement of the first surface to a second surface of the base reference substantially distinct from the first surface can be calculated to identify the thickness of the wear liner.

Abstract: The present invention relates to a method for measuring the diameter and/or the geometry of the diameter of a cylindrical object. The cylindrical object has a longitudinal axis and a cylindrical shell. The method comprises measuring in a contactless manner at a specific point in the direction of the longitudinal axis the momentary circumferential velocity of the cylindrical shell at specific time or the distance which the circumference of the cylindrical shell rotates, measuring revolutions of the cylindrical shell or the angle of rotation of the cylindrical shell simultaneously with the measuring of the momentary circumferential velocity at specific time or the distance which the circumference of the cylindrical shell rotates, and calculating the diameter of the cylindrical shell and/or the geometry of the diameter of the cylindrical shell at the specific point in the direction of the longitudinal axis. The present invention also relates to a measurement system for measuring the diameter and/or the geometry of the diameter of a cylindrical object and the use of the measurement system.
