Abstract
An arthroscope consists of a shaft which is inserted into the patient and a camera
head which can rotate about the shaft axis. In computer-assisted surgery that uses the
tracked arthroscope, the angle of the camera head with respect to the arthroscope
shaft must be known. This thesis investigates three methods which use computer
vision techniques to recover the shaft rotation angle from the live arthroscope video
feed. Five different trials were preformed using each method, and the computed
angles were compared to a gold standard using a rotary magnetic encoder. The best
method provided RSME of 1.7 degrees.
