As with the floor masks, this name must be unique among all other scene elements. After
naming the line it is automatically added to the scene element list.
In the examples shown above, a line always has two corners / points. However, a line can
have multiple points (corners) to fit all situations. Such a multi-point line can be created by
just going ahead drawing corner points in the scene. Figure 28 shows an example:
Figure 28: A multi-point line
An existing line can be modified by moving its corners or by dragging the whole line by
clicking-and-holding on a line edge.
The sensor supports up to 8 count lines. When the 8
th
line is drawn, the line drawing tool gets
disabled. One or more lines then need to be deleted to re-enable the line drawing tool.
3.2.7.9.5. Count zone
The count zone is the second counting and observation tool available with the PC2. A count
zone measures the occupancy of a defined zone. Every count zone provides a count level
which indicates the number of persons currently situated within the zone.
Drawing a count zone
A count zone can be drawn similar to the floor mask. By selecting the drawing tool “Zone”
one can simply draw the corner points of the zone polygon in the scene image. A count zone
can be finished by clicking on the first corner again, by double-clicking to create the last
corner, by disabling the “Zone” tool or by pressing [Esc] on the keyboard. As with the count
lines, after finishing, the user is asked to name the count zone before it gets automatically
added to the scene element list.
