Import Calibration Type

The Import Calibration Type is used to load a calibration file that has been created by an N Point or Sequential N Point Calibration Tool, and exported to the In-Sight vision system's local file system. The imported calibration file automatically calibrates the current job as soon as it has been loaded.

Note: Prior to selecting Import as the Calibration Type, first add and configure either an N Point or Sequential N Point Calibration Tool, and then export the calibration file to the In-Sight vision system's local file system.

The N Point and Sequential N Point Calibration Tools create a 2D transformation to convert between pixel and real-world coordinate systems. In this process, the tools account for linear and non-linear distortion, and offer a higher degree of accuracy than the X/Y Scale, Edge to Edge, X/Y Edge to Edge or Circle calibration methods, when five or more point pairs are used. The tool performs the following transformations:

  • Translation in two dimensions (using 2 or more point pairs).
  • Rotation about three axes (using 4 or more point pairs).
  • Scale in two dimensions (using 2 or more point pairs).
  • Perspective distortion (using 4 or more point pairs).
  • Parallelogramming or skewing (using 4 or more point pairs).
  1. Select Import from the Calibration Type drop-down menu.
  2. EasyBuilder will automatically examine your job for any calibration files generated by an N Point or Sequential N Point Calibration Tool, and load the calibration file. If you have created more than one calibration file, select your desired file from the File Name drop-down menu.
  3. From the Units drop-down menu, select the real-world measurement units that define the calibration: Microns, Millimeters (default), Centimeters or Inches.
  4. The calibration will be applied as soon as this option is selected and the values are configured.
