This paper describes the implementation of a 3D handheld scanning approach based on Kinect. User may get the 3D scans at a very fast rate using real time scanning devices like Kinect. These devices have been utilized in several applications, but the scanning lacks in the accuracy and reliability of the 3D data, which makes their employment a difficult task. This research proposed the 3D handheld scanning...
Image-to-patient registration process is required to use actively pre-operative images such as CT and MRI during operation for surgical navigation system. One method to utilize scanning data of patients and 3D data from MRI or CT images is dealt with in this paper. After 3D surface measurement device measures the surface of patient's surgical site, this 3D data is registered to CT or MRI data using...
In image guided surgery, image-to-patient registration process is required to use actively pre-operative images such as CT and MRI during operation. One method that utilizes 3D surface measurement data of patients among several image-to-patient registration methods is dealt with in this paper. After a hand held 3D surface measurement device measures the surface of patient's surgical site, this 3D...
This paper proposes a selective-gaze tracking method for a head-mounted stereo gaze tracker using trinocular epipolar geometry. As the tracker consists of one front-view camera and stereo eye-view camera to extract three-dimensional attentional points, the relationship between three cameras can be considered as a kind of trinocular vision system. A process of extracting a line of sight from each eyeball...
This paper suggests a head-mounted binocular gaze tracker working as an interfacing device for human-robot interaction. The purpose of the binocular gazes tracker is to extract the user-selective visual attention areas in three dimensional space and to let the robot know the current interests of human operators. In expanded 3D space, its calibration method utilizes two calibration planes in order...
