(b) Up to 6 linear edges (3 to 6) must be specified.
(a) The more edges are defined, the higher accuracy can be expected.
However, longer processing time will be required in proportion to the
specified number of edges.
(b) The figures show the linear edge Nos.

(c) Select linear edges which have interior angles close to 90°, each
formed by a side and the extension of an adjacent side.
At least one edge must be shifted from the other one by 45 to 135° or 225
to 315°

(d) Select linear edges which are 2.0 mm or more in length.
An edge must be perfectly straight without any irregularity.

(e) It is recommended that the parameters related to linear edges be
defined counterclockwise for easier management, starting with "Edge
1".
Example: As for the component shown below, the shadowed edges must
be selected.
Select "1", "2", or "3" (indicated in the figure below) as the last
remaining edge.
Any one of "1", "2", and "3" can be selected, causing no hin-
drance to the recognition.

However, when "1", "2", and "3" have different dimensions in length,
the selection of the longest linear edge will improve the accuracy of
the recognition.

Set the start position (coordinates X and Y) of the selected linear edge
in each data box.
Enter the distance from the reference position determined by the pa-
rameters in the "1", "2", "3", and "4" data boxes of the label "Outward

• Definition of Start Position (Coordinates X and Y)
The start position (coordinates X and Y) is determined according to
the selection of the lighting system ("Back Ltg" or "Front Ltg"), and
the brightness at both sides of set edges.
See the figure below for your reference and determine the start po-
sition (coordinates X and Y).
