Tilt Angle
Vertical Field of View
Pan Angle
Roll Angle
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
Virtual Ruler
Draw Horizon

actual person to gain the best results.
Adjust calibration tilt angle. Use this to best emulate the camera's tilt
angle.
Adjust the calibration vertical field-of-view. Use this to best emulate the
camera's vertical perspective.
Adjust the calibration roll angle. Use this to best emulate the camera's
pan perspective.
Adjust the calibration roll angle. Use this to best emulate the camera's
pan perspective.
Description
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.
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.
Select this option to make the green calibration grid transparent.
