pylon vTools: Calibration & Rectification
Camera calibration to precisely convert pixel coordinates to real-world coordinates
Creating the recipe
Access the workbench from the top menu.
Create a simple recipe featuring a Camera vTool and a Calibration vTool, either using the vTool pane on the left or by right-clicking on the Workbench pane.
Easily connect the Image output pin of the Camera vTool and the Image input pin of the Calibration vTool.
Select the Camera vTool and click Run to utilize the live camera image for calibration.
Tip: When editing an existing recipe, remember to Stop the currently running recipe.
The calibration process
Double-click the Calibration vTool to open the settings dialog and start the calibration process.
The calibration requires a calibration plate.
Select a calibration plate from the dropdown list that matches the size of your camera's field of view.
If you don't have a printout already, print it in its actual size and affix it to a sturdy, flat surface (such as an aluminum plate or thick cardboard) for optimal results.
Position the calibration plate within the camera's field of view at the same distance as your objects.
Click Next and Capture an image of the calibration plate.
The calibration process starts automatically, and upon completion, you can directly see the results.
Click Next and OK to return to your Recipe.
Tip: If using an existing image, ensure it was captured under the same conditions as your current setup to ensure accurate results.
