  • Patent number: 9541234
    Abstract: A measuring machine includes a measuring device and a protective cover covering the measuring device. The measuring device is configured to measure parameters of a work piece. The measuring device includes a control box, a supporting board, a light ring configured to illuminate the work piece, and a camera module configured to obtain images of the work piece. The cover is made of non-transparent material. A first side of the cover defines a cut-out and a first slot. A second side of the cover opposite to the first side defines a second slot corresponding in size and alignment with the first slot. One side of the control box is exposed from the cut. Two ends of the supporting board are positioned on the first and second slots and exposed from the first and second slots.

  • Publication number: 20150116486
    Abstract: An image measuring system includes an interface module, an automatic measuring module, and an outputting module. The interface module is configured to display an image of a workpiece. The automatic measuring module finds features on the image of the workpiece, constructs a coordinate system according to the searched features, and measures a distance from each point on the workpiece to the constructed coordinate system. The outputting module compares the distance with a predetermined tolerance range and outputs the distance and a compared result to the interface module.
