2). Adjust calibration settings as required. A user may perform basic calibration cameras via two
separate methods:
i. 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.
ii. Manual Configuration - Manually enter/adjust calibration values under Camera Setup. 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 entered and cannot be adjusted using Click-and-
Drag.
Right-click within the video preview for the following calibration tools:
