1.2.5 Screen Recognition

(1) Scr. Recog. Function

The machine performs only the two-point recognition.

(2) Center Recognition

It can be selected whether or not the center recognition should

be performed.

ON : The machine performs the center recognition.

OFF : The machine does not perform the center recognition.

Mark Y is recognized once and the camera is moved to the

posi-tion where the recognized fiducial mark is located at the

center of the visual field. After that, the fiducial mark is re-

recognized.

The positional accuracy is improved because the mark is

recognized at the center of the visual field (the spot of the lens

with less distortion).

(3) Fiducial Mark #1

X (horizontal) and Y (vertical)

Set the coordinates of the first fiducial mark.

Unit : mm

Recog. Mode

Select the recognition mode.

Mark :

This recognition mode uses fiducial marks.

Model :

The image taken with the recognition camera is regis-

tered as "Model" using the "Position Teaching" tab. This

mode uses the "Model" in place of fiducial marks.

Model + Mark :

This mode recognizes the image in the center of the

model as in the mark mode, after rough positioning with

the model mode.

Code

Set the code No. of the first fiducial mark for screen recogni-

tion.

Auto Gain Adj.

Select whether or not the automatic gain is adjusted when the

Screen recognition is tested.

ON : The automatic gain adjustment is performed.

OFF : No automatic gain adjustment is performed.

Gain, Level

This sets the amplification rate, when the signal of the image

(taken by the recognition camera) is converted to image data

showing brightness.

• When the gain is decreased, the contrast becomes

greater.

• When the level is decreased, all of the brightness be-

comes greater.
