11.3.3. Configuration
The localizer module includes the following configuration options:
• Coordinate System
• Search-Box.
• Teach Image
• Teach-Box.
11.3.3.1. Coordinate System
Objective
Details regarding the calculated output coordinate system can be displayed in the sub-
module. Input coordinate systems in the project tree can be linked against this output
coordinate system for tracking purpose.
Property
The following settings/results are displayed:
Phi
(degrees)
Rotation of the coordinate system in degrees
The following settings/results are displayed under origin:
X (px)
Coordinate of the sensor image coordinate system (see section 18.3)
Y (px)
11.3.3.2. Search Box
Objective
The area can be specified within which closest correspondence to the taught in area
should be detected. This area should include all possible positions of the feature to
be detected (especially high-contrast area, special shape, edge or corner), in order to
assure correct alignment.
Comparison with the taught in box is only conducted within the search area. A smaller
search box results in less processing time and a higher refresh rate. In addition to this,
a clearly delimited area increases process stability, because small, clearly defined
areas are less susceptible to interference.
Image Area
As a standard feature, the teach box with a size of 16 × 16 pixels is displayed at the
upper left-hand edge of the image in the image area. The teach box can be enlarged to
96 × 96 pixels. Processing time required by the module increases along with the size
of the teach box. Its position within the image area can be freely varied. The teach box
is then taught-in in the localizer module (see section 11.3.2).
Property
The following settings/results are displayed:
Width Width of the search box along the X-axis.
Height Height of the search box along the Y-axis.
The following settings/results are displayed under origin:
X (px)
Coordinate of the sensor image coordinate system (see section 18.3)
Y (px)
