Detect criteria for [Passing Detection]
Set the passing direction and decision point of the moving
object for the detection line that the moving object will
cross.
[Passing Direction]
Select the direction for moving objects to pass the
detection line. When an object that moves in the selected
direction passes the detection line, “line crossed” is
detected.
A preview display shows the selected passing direction
on the detection line in the image display area.
[Decision Point]
Select the decision point of a moving object in
accordance with a detection line. When a decision point
selected here crosses the detection line, “line crossed” is
detected. In the image display area, a cross mark is
displayed to indicate the decision point in the detection
frame.
[Object Size (%)]
Enter or use the slider to set the size ratio of moving
objects for the entire screen.
When a moving object exceeds the value set for [Object
Size (%)], it becomes a passing detection target.
When [Object Size (%)] is changed, an indicator frame
showing the size of the object is displayed for 1 second in
the center of the image display area, allowing
specification of the settings while checking the size ratio.
Note
• A ratio of up to 30% can be set for [Object Size (%)] in passing
detection.
• A passing detection event is notified only when the decision
line is crossed. Take care in setting the operation to be
performed when an event occurs.
