4.4.2.9.6 Additional Mimics
Additional mimics can be added to verify the calibration configuration. Select the Add Mimic option from the
menu.
4.4.2.9.7 Grid Transparency
By default the ground plane is displayed in transparent mode such that the video is clearer. The transparent
grid can be toggled by selecting the corresponding menu option.
4.4.2.9.8 Virtual Ruler
The calibration configuration control supports a virtual ruler. This can be useful for measuring distances along
the ground plane to objects of known size such as road lane widths, car park space widths etc. The virtual ruler
is effectively a "measurement stick" that measures the distance between two points along the ground plane
(not heights).
To use the virtual ruler, simply right click anywhere a point on the ground plane to anchor one end of the ruler
and select the option from the menu. It is then possible to move the other end of the ruler around the ground
plane to measure the distance between the anchor point and the current mouse position.
To exit from the virtual ruler mode, click the right button. The ruler disappears.
