  2. Linear motion - Wikipedia

    en.wikipedia.org/wiki/Linear_motion

    Since linear motion is a motion in a single dimension, the distance traveled by an object in particular direction is the same as displacement. [4] The SI unit of displacement is the metre . [ 5 ] [ 6 ] If x 1 {\displaystyle x_{1}} is the initial position of an object and x 2 {\displaystyle x_{2}} is the final position, then mathematically the ...

    The two have the same import data, the same 95° x 48° field of view and were created with the same program. The video shows the STITCH and CROP screenshots of the program as well as some details of two images as Microsoft Photos full-screen screenshots, a total of 20 screenshots twice, first quickly, then more slowly.

  4. Rectilinear lens - Wikipedia

    en.wikipedia.org/wiki/Rectilinear_lens

    While this example has been rectilinear-corrected by software, high quality wide-angle lenses are built with optical rectilinear correction. In photography, a rectilinear lens is a photographic lens that yields images where straight features, such as the edges of walls of buildings, appear with straight lines, as opposed to being curved.

  5. Motion - Wikipedia

    en.wikipedia.org/wiki/Motion

    [Also known as rectilinear motion] Reciprocal motion; Brownian motion – the random movement of very small particles; Circular motion; Rotatory motion – a motion about a fixed point. (e.g. Ferris wheel). Curvilinear motion – It is defined as the motion along a curved path that may be planar or in three dimensions.

  6. Indian Field Gun - Wikipedia

    en.wikipedia.org/wiki/Indian_Field_Gun

    Indian Field Gun Mark 2; Indian Field Gun Mark 3; The Light Field Gun (LFG) variant weights 2,380 kg (5,250 lb), but retains the same rate of fire and range as the IFG. The LFG can be broken down into two or three parts for easy transport and quickly re-assembled. The LFG can be heli-lifted and paradropped. [1] [2] The manufacture of the Light ...

  7. Fisheye lens - Wikipedia

    en.wikipedia.org/wiki/Fisheye_lens

    With appropriate software, the curvilinear images produced by a fisheye lens can be remapped to a conventional rectilinear projection. Although this entails some loss of detail at the edges of the frame, the technique can produce an image with a field of view greater than that of a conventional rectilinear lens.

  8. Curvilinear motion - Wikipedia

    en.wikipedia.org/wiki/Curvilinear_motion

    The motion of an object moving in a curved path is called curvilinear motion. [1] Example: A stone thrown into the air at an angle . Curvilinear motion describes the motion of a moving particles that conforms to a known or fixed curve.

  9. Perspective distortion - Wikipedia

    en.wikipedia.org/wiki/Perspective_distortion

    The mood effect of perspective distortion achieved by rectilinear extreme wide-angle lenses is that the resulting image looks grotesque and unsettling, while not looking as unrealistic as curvilinear fisheye lenses which display barrel distortion. The effect is especially noticeable the closer the camera is to the subject, as its amount ...
