Each camera is located directly in front of the LCD for each eye minimizing the eye displacement between the display viewpoint and the camera viewpoint, allowing the user to effectively "see through" the HMD with a video see-through AR view.
Free-viewpoint observation Users can freely alter the viewpoint of the camera, when it is controlled by frame-by-frame intermittent tracking.
The train falls on its side and, looking like a supersonic roly-poly, glides past the viewpoint of the camera.
A camera file contains a sequence of camera entries of the form: x y z tx ty tz ux uy uz, where (x, y, z) is the viewpoint of the camera, (tx, ty, tz) is the direction the camera is looking along, and (ux, uy, uz) is a vector pointing up from the camera perspective.
To solve the problem, a novel model and the corresponding calibration approach are presented, which take the sensor as an integrated structure with the viewpoint that the camera captures two virtual points formed by the same object point due to the reflection effects of the mirrors.
In real-world settings, the viewpoint of the camera cannot always be fixed relative to the subject, so view-invariant action recognition methods are needed.
Here, "viewpoint" refers to the camera's azimuth with respect to the target.
He also revolutionised film editing, shooting his many, violent action set-pieces with multiple cameras and viewpoints, running the cameras at different speeds, from 60 to 120 frames a second, after seeing what editor Lou Lombardo had achieved with similar effects on earlier projects.
Mathematical tools from projective geometry are employed for landmark identification, facilitating robust landmark recognition irrespective from the camera viewpoint.
