Global Setup

Description

This article will show you how to set the global rules for IVS analysis.

Depth of field calibration allows the camera to determine the corresponding relationship between the 2D image captured by the camera and the actual 3D object using one horizontal ruler and three vertical rulers that are defined by the user using the corresponding actual distance.

Example

Prerequisites

• Supported device with IVS feature

Metric to Imperial Conversion

• 1 Meter = 3.28 Feet
• 2 Meters = 6.56 Feet
• 3 Meters = 9.84 Feet

Example

Global Setup Best Practices

• The camera must be installed at a medium or distant view with an installation height of more than 3 meters.
• Scenes with parallel view or ceiling mounted are not supported
• Horizontal surfaces can be calibrated, not vertical walls or sloping surfaces
• Not applicable for scenes that have a distorted view such as captured by super wide-angle or a fisheye camera

Step by Step Instructions

1. Log into the web interface of the camera

2. Click Setting

3. Click Event > IVS

Click the tab labeled 'Global Setup'

4. The calibration zone must be created

Click inside the video frame to draw a frame

5. Left click to draw

6. The 3 vertical reference rules must be drawn.

These objects must be identical in height.

Toggle the button next to Vertical then click Add Rules

Then click inside the video frame to drag and draw the line

7. One Vertical ruler has been created in this scene

8.Repeat the same process twice to create 2 more Vertical rulers in the scene

9. The horizontal reference rule must be drawn.

Toggle the button next to Horizontal then click Add Rules

Then click inside the video frame to drag and draw the line

10. All rules complete

11. The "Actual Length" field allows you to set the actual distance (in meters) of the drawn rules.
