| 20080273211 | Apparatus and Method for Measuring the Surface of a Body - In a light-slit method, a first and a second measurement light projection on a surface of an object to be measured may be unambiguously identified as a first or a second measurement light projection by a camera when there is a support apparatus operating the camera and/or the measurement light projectors such that, in each light-slit recording of the camera, either the first or the second measurement light projection is visible to the camera. The possibility of unambiguous identification allows evaluating several spatially overlapping and not exactly aligned measurement light projections by means of a camera. | 11-06-2008 |
| 20090033947 | Method for repeatable optical determination of object geometry dimensions and deviations - A method for inspecting geometrical shapes of objects to determine selected dimensions thereof based on data characterizing such objects obtained through stereoscopic photographs taken by a pair of cameras with fields of view intersecting to thereby provide a photographic event measurement volume that includes at least a portion of each of such objects being photographed. The method involves using previously specified procedures to check on the cameras performance consistency in photographing from different positions, preparing the object to be inspected including providing reference point targets thereon, scanning that object with the cameras from different camera pair positions, processing the resulting data to represent the scan basis geometrical shape of the object, and orient it to compare with the dimensional specifications therefor. | 02-05-2009 |
| 20090091768 | Color Filter Inspection Method, Color Filter Manufacturing Method, and Color Filter Inspection Apparatus - Included are an illumination lamp ( | 04-09-2009 |
| 20090135434 | METHOD AND APPARATUS FOR DETERMINING THE TOPOGRAPHY AND OPTICAL PROPERTIES OF A MOVING SURFACE - The invention relates to a method and apparatus for determining the topography or optical properties of a moving subject. In the method at least two images (KX | 05-28-2009 |
| 20120206734 | RELIEF PATTERN DETECTION DEVICE - The present invention aims to provide a highly reliable relief pattern detection device | 08-16-2012 |
| 20140071459 | Shape Measuring Device, Shape Measuring Method, And Shape Measuring Program - The invention provides a shape measuring device, a shape measuring method, and a shape measuring program capable of easily adjusting a posture of a measuring object to a state appropriate for shape measurement before the shape measurement of the measuring object. A measuring object is irradiated with light having a pattern for posture checking by a light projecting unit before the shape measurement. An image of the measuring object captured by a light receiving unit is displayed on a display section in this state. The posture of the measuring object is adjusted with the measuring object being irradiated with the light having the pattern for posture checking by the light projecting unit. | 03-13-2014 |
| 20140253929 | APPARATUS AND METHOD FOR 3D SURFACE MEASUREMENT - An apparatus for 3D surface measurement of a target surface, the apparatus comprising: a first projector configured to project a fringe pattern onto the target surface; a second projector configured to project a fringe pattern onto the target surface; a first camera configured to capture the fringe patterns projected by the first projector and the second projector; a second camera configured to capture the fringe patterns projected by the first projector and the second projector; and a computer configured to perform fringe pattern processing of the fringe patterns captured by the first camera and the second camera and to perform data stitching and merging to obtain a 3D surface reconstruction. | 09-11-2014 |
