The following modules are currently implemented:
- Intrinsic calibration: Assuming a pinhole model, discover the camera parameters using a 6x9 checkerboard or 4x11 circle pattern image.
- Requires a videoCamera node be created
- Select the input image streamed from a PlusServer, via the OpenIGTLinkIF module.
- Select the StylusTipToCamera transform streamed from a PlusServer
- Tracker registration: This module enables the registration of an external tracker marker attached to the camera and the camera coordinate system
- Uses a tracked stylus that has been pivot calibrated in order to determine the pose of the stylus tip.
- User must manually identify the location of the stylus tip in the image by clicking 'Capture' and then clicking on the tip in the image.
VideoCamera Ray Intersection
- This module collects a number of rays in external tracker space and calculates the intersection point and mean distance error.
The following ideas may be implemented in the future:
A number of modules for calibrating and registering stereo cameras from within Slicer
