Camera‐to‐Probe Transform Tool

This page is up-to-date as of Parallax version 0.33.0

The Camera-to-Probe Transform Tool streamlines the process of registering correspondence points between the camera coordinate system (given by the calibration) and the probe's motor coordinates. It is accessed via the Tools menu:

Main Window > Tools > Transforms > Camera-to-Probe Transform Tool

This window is divided into three panels:

"Automation" Panel

Here, we can set the parameters of the automated trajectory that the probe will be moved through. The trajectory will progress along a cubical lattice. The parameters of automation are:

• Stage: Which stage to drive through the automation procedure.
• Resolution: The number of lattice points per dimension of the cube. 2 will lead to 8 correspondence points, 3 will lead to 27, etc.
• Extent: The side length, in microns, of the cubical lattice.
• Origin: The center of the cubical lattice in stage coordinates.

"Correspondence" Panel

Here, we collect the correspondence points to be used in the transform.

"Generate Transform" Panel

Here, we can enter some metadata and generate the transform:

• Name: The name to associate with the transform. Auto-populated with timestamp.
• "From" Coordinates: The name of the coordinate system that we are transforming from. Auto-populated as "camera".
• "To" Coordinates: The name of the coordinate system that we are transforming to. Auto-populated as "probe".

When ready, click the "Generate" button to generate the transform. The transform will be added to the the dropdown menu in the Transform Panel of the Main Window, and from there you can save the transform to disk.
