    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.

    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.

    Abstract: The present invention provides for a sealer/primer that is generally cured at low bake temperatures. The composition utilizes a resin system to provide both conductivity and adhesion of the coating onto plastic substrates. The present invention uses a polyester, such as one that includes unsaturated polyester, in combination with other resins, including an acrylic, crosslinking agent and conductive pigment to create a conductive primer that can be cured at low temperatures. The composition can be applied through traditional application equipment, seals the surface of the substrate to which it is applied, and cures to an acceptable surface for further processing, such as painting.

    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.
