Vision Assistant can calibrate images containing distortion in order to return accurate measurements. The Image Calibration step calibrates images so that inspection results are returned in real-world units.

Calibrating an image is a two-step process.

  1. Use the Calibration Training Interface to specify the type of calibration, the calibration parameters, and the real-world unit in which you want to express measurements.
  2. Use the Image Calibration step to apply the computed calibration to the image during the inspection process.
Tip Whenever possible, position the camera perpendicular to the object to minimize perspective distortion in the image. Use a high quality lens or telecentric lens to minimize nonlinear distortion in the image.
