MxEasy User Manual: System Configuration
• Low-light supression: Image analysis is disabled if the current illumination falls below
the set value.
• Counting line deadtime: Specify the period of time within which an object that has
crossed a line is no longer counted by the line. This setting increases the accuracy of
the object counting process if objects are moving on the line in close proximity and
crossing the line more than once.
Environment Settings
The quality of the analysis results is dependent on the lighting and environmental conditions
to which the camera is exposed. You can set various parameters that adapt the camera
to dierent lighting and environmental conditions in order to maintain good quality. Three
environment settings are predefined for this purpose. It is also possible to customize the
environment setting:
• Artificial light, no shadows: Select this option if the environment to be analyzed is
illuminated by artificial light only and there are no shadows cast by the objects to
be detected.
•
Sparse sunlight, blurred shadows: Select this option if the environment to be analyzed
is subject only to minimal changes in illumination (such as sunlight) and any shadows
cast are of a diuse nature.
• Heavy sunlight, well-defined shadows: Select this option if the environment to be
analyzed is subject to serious changes in illumination (such as a large window) or
harsh shadows arise.
• Custom setup:
Selecting custom setup opens options and checkboxes that can be
used to select and link dierent illumination situations and shadow
detection methods:
–
Constant illumination: Select this option if there will be no changes
in illumination in the environment to be analyzed, for example, in a
windowless hall. This option also allows you to follow objects that do
not move for several seconds. It has a positive eect on the frame
rate as it generates a very low computing load.
–
Slow change in illumination: This option is suitable for rooms with few
windows. Changes in illumination occur gradually and are not distinct.
– Quick change in illumination: This option is particularly well-suited
for rooms prone to sharp illumination changes, such as is the case
in large windows. The computing load is highest here, which has a
negative eect on the frame rate.
–
Shadow: Link the illumination situation selected with a shadow
detection method. It is helpful to activate the first shadow detection
method for unevenly structured or dark backgrounds. Use the second shadow
detection method for bright or finely structured backgrounds. This can be set with
