  2. Virtual image - Wikipedia

    en.wikipedia.org/wiki/Virtual_image

    The magnification of the virtual image formed by the plane mirror is 1. Top: The formation of a virtual image using a diverging lens. Bottom: The formation of a virtual image using a convex mirror. In both diagrams, f is the focal point, O is the object, and I is the virtual image, shown in grey. Solid blue lines indicate (real) light rays and ...

  3. VR photography - Wikipedia

    en.wikipedia.org/wiki/VR_Photography

    VR photography (after virtual-reality photography) is the interactive viewing of panoramic photographs, generally encompassing a 360-degree circle or a spherical view. The results is known as VR photograph (or VR photo ), 360-degree photo , [ 1 ] photo sphere , [ 2 ] or spherical photo , as well as interactive panorama or immersive panorama .

  4. Real image - Wikipedia

    en.wikipedia.org/wiki/Real_image

    A real image occurs at points where rays actually converge, whereas a virtual image occurs at points that rays appear to be diverging from. Real images can be produced by concave mirrors and converging lenses, only if the object is placed further away from the mirror/lens than the focal point, and this real image is inverted. As the object ...

  5. Virtual photography - Wikipedia

    en.wikipedia.org/wiki/Virtual_photography

    For the most part, virtual photographers share the same motivations as "real life" photographers, including a desire to capture visually interesting images, preserve memories, and demonstrating technical expertise. [2] One of the earliest known works of virtual photography was Thirteen Most Beautiful Avatars by Eva and Franco Mattes.

  6. Virtually imaged phased array - Wikipedia

    en.wikipedia.org/wiki/Virtually_Imaged_Phased_Array

    This is the fundamental difference from an Echelle grating, where a similar phased array is formed in the real space. The virtual images of a light source in the VIPA are automatically aligned exactly at a constant interval, which is critical for optical interference. This is an advantage of the VIPA over an Echelle grating.

  7. Visual computing - Wikipedia

    en.wikipedia.org/wiki/Visual_Computing

    Visual computing [1] is a fairly new term, which got its current meaning around 2005, when the International Symposium on Visual Computing first convened. [2] Areas of computer technology concerning images, such as image formats, filtering methods, color models, and image metrics, have in common many mathematical methods and algorithms.

  8. Pinhole camera model - Wikipedia

    en.wikipedia.org/wiki/Pinhole_camera_model

    A practical implementation of a pinhole camera implies that the image plane is located such that it intersects the X3 axis at coordinate -f where f > 0. A point R at the intersection of the optical axis and the image plane. This point is referred to as the principal point [2] or image center.

  9. Image rectification - Wikipedia

    en.wikipedia.org/wiki/Image_rectification

    A camera (red) rotates about the blue axis by 5° to 90° (green), as the images are rectified by projection to the virtual image plane (blue). The virtual plane must be parallel to the stereo baseline (orange) and for visualization is located in the center of rotation. In this case, rectification is achieved by a virtual rotation of the red ...
