4.3.2 Configuring Camera Calibration
Perform the following steps to three-dimensionally measure and quantize the image from the camera. From this information, you
can calculate the size of every target. The VCA detection is more accurate if the camera calibration is configured.
TASK 1: Auto Calibration Steps:
1. Open the Camera Calibration menu. Go to: Setup | VCA | Camera Calibration .
2. Make sure only one person appears in the live view (see left image above), and enter the person’s height in the Target Height
text field.
3. Click

to start auto calibration.
NOTE
•
Make sure there is no moving objects in the view except for the person.
•
The auto calibration starts when the person is totally seen in the camera’s view, and ends when the person is in the endpoint (The
endpoint-to-camera distance(m) equals 4 times the lens focal length(mm)). For example, for a 7 mm lens, the recommended
endpoint is 28 m (7*4).
•
Once auto calibration staMake sure the walking route covers the left, middle, right of image.
•
rted, the person should start to walk in a zigzag course.
•
The auto calibration duration should be no shorter than 10 seconds, and no longer than 10 minutes. Walking in a double Z zigzag is
theoretically enough.
•
For leave/tree interference in the live view, shield settings is recommended.
