Optical surgical instrument tracking system based on the principle of stereo vision

Optical surgical instrument tracking system based on the principle of stereo vision.

Optical tracking systems are widely adopted in surgical navigation. An optical tracking system is designed based on the principle of stereo vision with high-precision and low cost. This system uses optical infrared LEDs that are installed on the surgical instrument as markers and a near-infrared filter is added in front of the Bumblebee2 stereo camera lens to eliminate the interference of ambie...

Model-Based Object Tracking Using Stereo Vision

Robust and accurate object recognition and tracking is a necessary pre-requisite for visual servoing tasks. While most approaches use monocular vision in order to solve this problem, this paper presents a new approach using disparity images provided by a stereo vision system from which 3-D models are reconstructed. We use a segmentation procedure based on a simple region growing process to segm...

Optical imaging of cervical precancerous lesions based on active stereo vision and motion tracking.

A 3-D optical imaging system based on active stereo vision and motion tracking is built to track the motion of patient and to register the time-sequenced images of cervix recorded during colposcopy. The imaging system is evaluated by examining human subjects in vivo before routine colposcopy examination procedures. The system tracks the motion of patient accurately. The temporal kinetics of the...

Optical imaging for medical diagnosis based on active stereo vision and motion tracking.

This study aims to develop a novel imaging technique to improve the accuracy of the colposcolpic diagnosis of cervical cancer. An optical imaging system based on active stereo vision is built to measure the 3-D surface topology of cervix and track the motion of patient. The information of motion tracking are used to register the time-sequenced images of cervix recorded over the period of examin...
