9.3.2 Configuring Camera Calibration
Perform the following steps to three-dimensionally measure and quantize the image
from the camera, and then calculate the size of every target. The VCA detection will
be more accurate if the camera calibration is configured.
 TASK 1: Auto Calibration
Steps:
1. Enter Configuration > VCA > Camera Calibration.
2. Make sure only one person appears in the live view, and input the person's
height in the Target Height text field.
3. Click to start auto calibration.
Notes:
 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)). E.g, for 7mm lens, the recommended endpoint is 28m
(7*4).
 Once auto calibration started, the person should start to walk in a zigzag
course.
 Make sure the walking route covers the left, middle, right of image.
 The auto calibration duration should be no shorter than 10s, and no
longer than 10min.Walking in a double Z zigzag is theoretically enough.
