| Summary: | The development of Image-guided Surgery (IGS)
system as an assistant tool in medical navigation has led to new
challenges for researchers to enhance the accuracy of the medical
surgery. In IGS, a stereo camera is used to find the position of
medical markers and visualize it on the screen of the surgeon.
However, the line of sight (LOS) between the camera and the
markers causes the stoppage of the tracking system if it cut
during the operation. This paper presents a multi-stereo camera
system to overcome the LOS problem, and to improve the
accuracy of the IGS system. A pair of stereo cameras has been
used to recognize and detect the reference markers and visualize
a patient's body part and a surgical needle. A multi-stereo
camera has generated a very good accuracy of 3D visualization
with (2.88 mm) of root mean square error (RMSE). Image
filtering techniques have been used to process the captured
images. Thus, IGS system based on multi-stereo camera,
contributes promising results of medical navigation and enhances
the capabilities of IGS system. |
