(4) When you click the "Job Editing" screen [Processing Condition(2)] tab, the conditions for
executing blob image processing are set.
When you change a displayed setting item, then click the [Test] button, the results of image
processing under the specified conditions are displayed at the main screen [Camera Image], so
check whether or not the work is correctly recognized.
For details on the setting items, see "Table 9-9 List of [Search Area and Recognition Condition
(1)] Tab Items".

* For all the items, if a value outside the range is input, it is replaced with the upper or lower limit
value near the image going out of focus.

Setting
range
1 - 100
This sets what degree of recognition is required for recognition of work
detected with the threshold specified with the grayscale threshold.
For the vision sensor, the degree of matching of the detected work is
expressed as 1-100%. Work whose degree of matching is lower than
the value set here is not recognized.
1 - 255
This sets the grayscale threshold. When the "Auto Setting" checkbox is
checked, the value is set automatically from the images captured.
None
Returns the recognized work results in the specified sort order.
X
When "None" is specified, the results are returned with the work sorted
Y
in order of high recognition ratio.
This sorting is used for cases such as when multiple work pieces are
detected and you want to grasp the work in order from left to right in the
image.
The "X" and "Y" specified here indicate the "X" and "Y" at the red frame
displayed with the search area setting.
-180 - 180
When outputting the recognized work results, this function adds the
specified offset amount to the detection angle.
When registering patterns, this is used if the 0˚-tilt image can not be
captured.
None
This selects the data when outputting the recognized work coordinate
1 - 10
value converted to the robot coordinate value.
Work information can be converted to the coordinate systems for up to
three robots and sent.
Therefore, it is possible to select calibration numbers for three robots.
* The figure above shows a screen assuming a system with one robot.
When a system is selected with three robots, [Robot 2:] and [Robot 3:]
display appears.
