Camera Calibration
Before detection zones can be defined for the IntelliSight Camera, the camera
must be calibrated in order to teach the camera how to translate from flat 2D
video to 3D space. The camera must be mounted in a forward facing or receding
configuration, not in a side-fired configuration.
1. On the Device screen for the camera, click
C
AMERA
C
ALIBRATION
.
The following appears.
2. Move the cursor to one of the corner or lane markers, then click and drag to
the desired location.
NOTE:
It is important that the calibration overlay has parallel lines. This
would not be a problem for most intersections where the lane lines
are parallel to one another as in the image shown below. If the lane
lines are not parallel, then the calibration overlay must be set
differently.
3. Repeat for each corner/marker until the zone covers the detection area and
calibration lines are arranged so that they line up with lane lines.
4. To add additional lanes to the zone, in the Commands section click
A
DD
L
ANE
.
5. Adjust the markers to line up with the lane lines.
