### Multi-Dot Calibration Utility

##### Introduction

The Multi-Dot Calibration Utility allows you to calibrate a MicroHAWK or HAWK MV-4000 using a multi-dot calibration target instead of the typical 8-dot pattern. Such a multi-dot target allows for more accurate pixel-to-world conversions, enabling more reliable real-world measurements. This is especially true for the wider-angle lenses typically used in modern machine vision applications.

The utility is installed on your PC when you install AutoVISION. It can be found in the Windows Start Menu under OMRON AutoVISION > Tools:

Camera calibration with the Multi-Dot Calibration Utility is a six-step process:

1. Select Device;
2. Set Up Camera and Align Target;
3. Enter Calibration Pattern Information;
4. Position Region of Interest to Surround Target;
5. Start Calibration and Check Results;
6. Save Calibration File to Disk or Camera.

Each of these steps has its own screen within the utility.
