[High Speed 1]

Smart Matching

Detects the presence (or absence) of a pattern (object) in the search area that matches the template registered. Detection of sub-pixel position possible with gray scale matching. In addition, using the gray scale differential processing function, shape inspection, e.g. to detect chips or other flaws in an object, can also be carried out simultaneously.

Feature Extraction

Features, such as the number of objects, the area, central coordinates, angle of the main axis, projection width or perimeter length, can be extracted using a binary image.

Gray Scale Window

An area can be created in a 256 gray scale image, with a rectangular, circular or polygonal shape over the area where object detection is to take place. An average value for the brightness data (gray scale value) for all pixels in that area can be calculated.

Gray Scale Edge

The distance between lead pins or pitch size can be measured for an inspection object. Parameters allow settings to be made in great detail. Using the extreme accuracy of sub-pixel processing, the edge in question can be reliably extracted for a wide variety of object states.

Judges whether a certain amount of area for an object is present using a binary image. High-speed processing is 23 times as fast as previous models, even when multiple inspection areas are specified.

Determination of position and simple size measurement can be carried out at approximately twice the speed of previous models. There is no effect on inspection speed even if the inspection area is increased for purposes of stability.
