line (the green vertical line) and several blue horizontal lines appear in the live
view image.
Camera Calibration: You set the width (usually the shoulder breadth) of a person
for counting. Well-set calibration parameters will help increase the counting
accuracy.
Blue Horizontal Lines: One blue line indicates the detected width (usually the
shoulder breadth) of a passing person. Up to eight blue lines can be shown on
each side of the detection line. These lines are reference for calibration setting.
Calibration Line (Green Vertical Line): The distance from the left endpoint to the
calibration line (calibration line width) indicates the set width of a person. You
can drag the calibration line to adjust the distance according to the blue line
distribution.
Advanced: You can precisely adjust the position and the size of detection line
and calibration line.
1) Dragging the cursors or inputting values in the text fields to set the
