is the rotation matrix by which b is rotated in relation to a; t is the translation vector from a to b; n and d are the normal vector of the plane and the distance from origin to the plane respectively. K a and K b are the cameras' intrinsic parameter matrices. The figure shows camera b looking at the plane at distance d.
3D visualization of a sphere and a rotation about an Euler axis (^) by an angle of In 3-dimensional space, according to Euler's rotation theorem, any rotation or sequence of rotations of a rigid body or coordinate system about a fixed point is equivalent to a single rotation by a given angle about a fixed axis (called the Euler axis) that runs through the fixed point.

The Start menu may be launched either by pressing ⊞ Win (the Windows key) on a keyboard or its equivalent on a tablet device, pressing Ctrl+Esc on a keyboard, or by clicking on the visual Start button. With the exception of Windows 8 and Windows Server 2012, the Start button can be found on the taskbar. The Start button on Windows Server 2012 ...
A rotational mouse is a type of computer mouse which attempts to expand traditional mouse functionality. [1] The objective of rotational mice is to facilitate three degrees of freedom ( 3DOF ) for human-computer interaction by adding a third dimensional input, yaw (or Rz), to the existing x and y dimensional inputs.
The camera matrix derived in the previous section has a null space which is spanned by the vector = This is also the homogeneous representation of the 3D point which has coordinates (0,0,0), that is, the "camera center" (aka the entrance pupil; the position of the pinhole of a pinhole camera) is at O.
Shaky camera, [1] shaky cam, [2] jerky camera, queasy cam, [3] run-and-gun [4] or free camera [4] is a cinematographic technique where stable-image techniques are purposely dispensed with shaking. It is a hand-held camera , or given the appearance of being hand-held, and in many cases shots are limited to what one photographer could have ...
The spinning disc then exposes the new frame of film. The nature of light-sensitive film requires a shutter to block the light and prevent smearing of the image as the film is advanced through the camera. Digital sensors do not require a rotary shutter, although some high-end digital cinema cameras do have them.
Working principle of a Maltese cross or Geneva drive Animation of a rotating shutter. The film is transported one frame when the shutter is blocking illumination of the film. An intermittent mechanism or intermittent movement is a device or movement which regularly advances an object, web, or plastic film and then holds it in place. This ...
