Software Module
Property
Unused Error
Correction
As data codes are redundant codes, errors in the modules
or codewords can be corrected. The amount of error cor-
recting capacities which is not already used by the present
data code symbol is expressed in the Unused Error Cor-
rection quality. In a way, this grade reflects the reliability of
the decoding process. Note, that even codes with an Un-
used Error Correction grading of 0, which could possibly
mean a false decoding result, can be decoded in a reliable
way, because the implemented decoding functionality is
more sophisticated and robust compared to the reference
decode algorithm proposed by the standard
Mean Light
Estimation for the quality of the processed image The
value of Mean Light is not a grade specified with AIM DPM-
1-2006 standard. It is an estimation for the quality of the
processed image computed as the mean gray-scale value
of the centers of the light data code modules. It is a value
between 0.0 and 1.0, corresponding to 0% to 100% of the
maximum gray-scale value.
Note: More detailed information regarding the results of quality testing can be
found in the corresponding standards.
Envelope The read code surrounding polygon.
11.12.3.2. Search Box
Objective
The image area within which codes are detected can specified. With the help of a
smaller search box, transmission time is reduced and the refresh rate is increased.
Note: The area to be examined must be lie completely within the search box.
Image Area
By default, the search box encompasses the entire camera image. It appears in the
image area as a dashed frame, where it can be adjusted.
Property
Search box settings are also displayed in the settings/results area.
Width Width of the readout box
Height Height of the readout box
The following settings/results are displayed for the search box under origin:
X (px)
Coordinate of the sensor image coordinate system (see section 18.3)
Y (px)
