9.3.2 Perimeter Protection Configuration
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.
Before you start:
Make sure that we have known the actual height of the person in the scene.
Steps:
1. Configure the display information and snapshot settings.
2. Set the Auto Calibration.
a) Check the checkbox of Camera Calibration to enable this function.
b) Make sure only one person appears in the live view, and input the person's
height in the Target Height text field.
c) 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.
For leave/tree interference in the live view, shield settings is recommended.
3. When the person exits, Click to stop auto calibration.
