  • Patent number: 8437077
    Abstract: A measurement apparatus includes a lamp mount including a first mount and a second mount. The first mount has a first cavity to mount an observation module. The second mount has a second cavity to mount an image capture module. The measurement apparatus further includes a plurality of light modules mounted on an undersurface of the lamp mount. The second mount is disposed with an included angle relative to a first axis of the first cavity so that a second axis of the second cavity and the first axis converge on a point. The undersurface of the lamp mount is concave so that light from the light modules tilts toward the first axis, and the light and the first axis also converge on the point.

  • Patent number: 8437981
    Abstract: In a method for verifying manufacturing accuracy, a point cloud of a workpiece is read. A first determined point is determined according to the first point of the point cloud and a second determined point is determined according to the final point of the point cloud. A first line, a second line, and a third line are all located by respectively connecting the first point and the first determined point, the final point and the second determined point, and the first determined point and the second determined point. Qualification of the workpiece is determined by measuring a first angle of the first line and the third line, a second angle of the second line and the third line, a first distance between the first determined point and the second line, and a second distance between the second determined point and the first line.

  • Patent number: 8237790
    Abstract: A system and method for positioning a portion of an object to be measured includes installing a digital camera adjacent to a charge coupled device (CCD) lens of an image measuring machine, setting positioning parameters corresponding to different positions of the digital camera on a Z-axis of a world coordinate system, receiving an image of the object captured by the digital camera, and selecting corresponding positioning parameters according to a position of the digital camera. The method further includes selecting a point of the portion of the object in the image, calculating coordinates of the selected point in a plane of the CCD lens, and controlling the CCD lens to move to the calculated coordinates so as to position the CCD lens on the portion of the object.

  • Patent number: 8169531
    Abstract: A system and method for automatically focusing an optical lens controls the light generated by a light-emitting device of an image measuring machine to penetrate a glass sheet, so as to project a picture of the glass sheet onto an object. The system and method further moves an optical lens along a Z-axis of the image measuring machine to capture one or more digital images of the object, and computes a definition value of each captured digital image. Furthermore, the system and method obtains a focus position corresponding to the highest definition value of the captured digital image.

  • Patent number: 8121416
    Abstract: A system and method for determining inflection points in an image of an object includes obtaining the image of the object, performing binary image processing on a border of the image to obtain border points, selecting a predetermined number of the border points to fit a straight line, calculating a vertical distance between each selected border point and the straight line, and obtaining a total distance. The method further includes adding a new border point to the selected border points if the total distance is less than a predetermined value, so as to fit a new straight line and do a loop cycle, otherwise, regarding a last border point of the selected border points as an inflection point, and sequentially selecting the predetermined number of other border points to fit another new straight line.

  • Publication number: 20110211730
    Abstract: An image measuring device comprises a storage, a processor, an acquiring module, a positioning module and a determining module. The acquiring module acquires an image of a production object by scanning the production object. The positioning module positions the image of the production object in a coordinate plane according to predefined parameters and acquiring the edge of the image of the production object. The determining module determines whether the difference between the positioned image and the predefined parameters is over a tolerance, wherein the acquiring module, the positioning module and the determining module are stored in the storage and controlled by the processor.
