Evaluation of a miniature electromagnetic position tracker.
The advent of miniaturized electromagnetic digitizers opens a variety of potential clinical applications for computer aided interventions using flexible instruments; endoscopes or catheters can easily be tracked within the body. With respect to the new applications, the systematic distortions induced by various materials such as closed metallic loops, wire guides, catheters, and ultrasound scan...

متن کاملCheckerboard Tracker for Camera Calibration
The checkerboard extraction process is an important pre-preprocessing step in camera calibration. This project attempts to implement the checkerboard extraction processes using methods learned from EE368. This includes the isolation of the checkerboard using morphological operations. The benefit of the approach is that it is efficient since morphological operations can be implemented efficientl...
متن کاملEvaluation of Rotation Correction Techniques for Electromagnetic Position Tracking Systems
Electromagnetic position tracking devices are an integral part of many modern virtual reality systems. However, they have an inherent accuracy problem due to the dependence on the local electromagnetic field that can be easily distorted by a presence of magnetically active elements near the tracker’s transmitter or receiver. Several analytical techniques have been proposed to overcome this limi...
