Machine Vision

Machine vision is to grant visual and judging ability of a human to the machine as technology for hardware and software system to process cognitive and judging ability of human.
  • 1. MACHINE VISION SOFTWARE

    As relevant to the brain of a human, it sets test items according to the subjects and criteria to distinguish conformance and non-conformance while serving a role of judging the conformance based on the video images acquired by a camera.
  • 2. TRANSPORTATION SYSTEM

    This serves a role of processing error and collecting relevant information after camera in a correct position acquiring the video images depending on the specifications, appearances, and textures of subjects.
  • 3. SEPARATING SYSTEM

    It serves a role of marking non-conformance or classifying non-conforming items according to the judgment by the software
  • 4. MACHINE VISION CAMERA

    This is the camera exclusively designed to be optimized to automated facilities unlike regular digital cameras or DSLR serving a role of human eyes.
  • 5. MACHINE VISION ILLUMINATION

    Requiring relatively high amount of light depending on the speed or form of moving items, this is the light specifically designed to solve heat emitting issues or satisfy various conditions.
Applicable Areas
If requiring judging the seal or scratch or abnormal conditions of the surface,
line scan is used to proceed surface test.
At this time, high-magnification and low-distorting lens are used along with clear boundary in order to acquire precise image.
  • Normal surface conditions
  • [NG]Hole due to abnormal seal or stamp
  • Scratch occurring when using after the [NG]
Semi-conductor wafer test and automatic extraction of non-conforming segment
  • STEP 01

    Acquire the image of WAFER
  • STEP 02

    Primary processing of acquired image
  • STEP 03

    Secondary processing of acquired image
  • STEP 04

    Make the area Blob
  • STEP 05

    Blob Filtering-1 (small area)
  • STEP 06

    Blob Filtering-2 (big area)
Centering test of lathe-processed items
  • It is possible to determine sizes of each location and if centers of upper/lower lathe-processed areas are consistent for lathe-processed items. At this time, it is required to acquire precise image without distortion along with clear boundary.
  • - Use line scan to acquire precise image in super high resolution
    - Use tele-centric lens to extract edge on the straight line without distortion
Test on the surface of Roll-to-Roll type and products with high-glossing surface
  • Abnormal size or cutting and protruded materials
  • Foreign substances inside, scratch, bubble, and crease
  • Stamping
  • Passing the boundary of materials, insufficient materials, penetrating cutting line, and etc.
