Image Recognition System

Features

  • It is possible to identify shape and color of target items by Image Processing.
  • By using this technology foreign objects in liquid can be identified.
  • We can provide total visual inspection system, not only Image Processing Software.
  • You can request about resolution, lens magnification of the camera and lighting unit.

Examples

Examples
  Detection of Foreign Object in Liquid
(Under Development)
Pressure Distribution of Pressure-Sensitive Paper
Resolution 1600 x 1200 (Pixels) 640 x 480 (Pixels)
Image Resolution 100um 460um
Image Input by Camera JPEG File
Positioning Automatic -
Controller by PC by PC
Image Processing
(Example)
The quality is judged automatically detecting the mixing foreign object in liquid.
(Necessary to evaluate it with actual target Item.)

detecting the mixing foreign object in liquid

The system calculates pressure statistical value and shows pressure graph by contrast of pressure-sensitive paper.

  Crystal Distribution of Polysilicon Alignment
Resolution 640 x 480 (Pixels) 1280 x 1024 (Pixels)
Image Resolution 11nm (SEM) 1.4um
Image Input JPEG File by Camera
Positioning - Automatic
Controller by PC by PC
Image Processing
(Example)
The system calculates size of crystal, boundary length, quantity and degree of circularity by divided area of each crystal.
*Need to optimize by sample image.
Detected Crystal Number: 46
Average Crystal Area   : 103,762 (nm2)

Micro Crystal

The system calculates shift amount of position by 2 shot image of alignment marks.
