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.

Note: Global setup is for the Fast-Moving IVS feature

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
