The following calibration specifications are available for configuration:
VCA Calibration Spec
Description
Preset Select
Select a preconfigured preset. Presets include:
Overhead, 60 Degree
Lookdown, 30 Degree Lookdown
.
Height
Adjust calibration height. Use this to best emulate the height of the
camera from the ground. Note the mimic size in comparison with an
actual person to gain the best results.
Tilt Angle
Adjust calibration tilt angle. Use this to best emulate the camera’s tilt
angle.
Vertical Field of View
Adjust the calibration vertical field-of-view. Use this to best emulate the
camera’s vertical perspective.
Pan Angle
Adjust the calibration roll angle. Use this to best emulate the camera’s
pan perspective.
Roll Angle
Adjust the calibration roll angle. Use this to best emulate the camera’s
pan perspective.
Steps:
1).
To begin calibration, adjust calibration settings as required. A user may perform basic
calibration cameras via two separate methods:
1).
Click-and-Drag
. - For this method, click and drag the green calibration grid to satisfactorily
emulate the camera’s height, tilt perspective, and field of view. The mimics may be moved
around the image to help the user gauge perspective. The mouse scroll wheel is also utilized to
adjust camera height, and consequentially the size of the calibration grid and mimics. Use
resizing of these elements to anticipate average object size.
2).
Manual Configuration
- Manually enter/adjust calibration values under the
Camera Setup
section
.
As the user enters values, the calibration overlay on the live preview will react
accordingly.
3).
If required, adjust
Pan Angle
and
Roll Angle
under the
Advanced Parameters
section using the
slider bars. As the sliders are moved, the calibration overlay over the preview image will react
accordingly. Advanced Parameters must be manually entered and cannot be adjusted using
the Click-and-Drag technique.
4).
Right-click within the video preview area for the following calibration tools:
Right-Click Option
Description
Virtual Ruler
Select this tool to anchor a virtual ruler from the point-of the right click.
Drag your mouse across the image to extend the ruler. Use this feature to
ensure accurate perspective calibration settings.
Draw Horizon
Select this option to add a drawn horizon line to the calibration grid. This
horizon line will be visible when the camera’s tilt angle is twenty degrees
or less.
Transparent Grid
(enabled by default)
Select this option to make the green calibration grid transparent.
