Scene group
32 units are incorporated into a scene for sorted measurement.This is convenient for managing scenes
on a per category basis.
Reference:
Center of gravity
The images with white pixels are cut into paper of a certain thickness, and when one point is used to
support the paper, the point which enables the paper to balance is called the center of gravity. The
center of gravity of a circular object is the center of the circle, the center of gravity of a rectangle is the
intersection of two diagonal lines.
Processing item
Single units that constitute measurement processing. Scenes (measurement flow) are created by
registering processing items in units.
Processing unit
A unit that constitutes measurement processing.Scenes (measurement flow) are created by setting
8
processing items in processing units.
Reference:
Correlation value
0 to 100 are used to represent the degree of similarity with an acceptable object.Namely, higher values
indicate higher degrees of similarity.
Flow control
If the processing speed of the receiving side is slower than that of the sending side when data is being
transferred, the receiving side will send interruption commands to the sending side or send
re-admittance commands and then adjust the transmission speed.
There are two flow control methods: "Hardware Flow Control" and "Software Flow Control". With this
product, "Software Flow Control" is used to adjust transmission speed.
Model
The image pattern that serves as the inspection target. Characteristics portions are extracted from
images of the object and registered as model registration.
