  2. Camera auto-calibration - Wikipedia

    en.wikipedia.org/wiki/Camera_auto-calibration

    In the visual effects industry, camera auto-calibration is often part of the "Match Moving" process where a synthetic camera trajectory and intrinsic projection model are solved to reproject synthetic content into video. Camera auto-calibration is a form of sensor ego-structure discovery; the subjective effects of the sensor are separated from ...

  3. Calibration - Wikipedia

    en.wikipedia.org/wiki/Calibration

    The formal definition of calibration by the International Bureau of Weights and Measures (BIPM) is the following: "Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties (of the calibrated instrument or ...

  4. Video calibration software - Wikipedia

    en.wikipedia.org/wiki/Video_calibration_software

    Video calibration software is software used to improve the quality of commercial video reproduction.. Organizations such as the Society for Motion Picture and Television Engineers (SMPTE), the Commission Internationale de l'Eclairage, the Advanced Television Systems Committee (ATSC), and the International Telecommunication Union (ITU) have established standards for the proper transmission and ...

  5. Calipers - Wikipedia

    en.wikipedia.org/wiki/Calipers

    Oddleg calipers, Hermaphrodite calipers, or Oddleg Jennys, as pictured on the left, are generally used to scribe a line at a set distance from the edge of a workpiece. The bent leg is used to run along the workpiece edge while the scriber makes its mark at a predetermined distance, this ensures a line parallel to the edge.

  6. Camera resectioning - Wikipedia

    en.wikipedia.org/wiki/Camera_resectioning

    To perform a full calibration by the Zhang method, at least three different images of the calibration target/gauge are required, either by moving the gauge or the camera itself. If some of the intrinsic parameters are given as data (orthogonality of the image or optical center coordinates), the number of images required can be reduced to two.

  7. Vernier scale - Wikipedia

    en.wikipedia.org/wiki/Vernier_scale

    The standard for a caliper is usually a constant of 0.02 Vernier caliper scale with the normal 0.02 vernier constant, showing measurement of object at 19.44 mm to two decimal places. The use of the vernier scale is shown on a vernier caliper which measures the internal and the external diameters of an object.

  8. Gauge block - Wikipedia

    en.wikipedia.org/wiki/Gauge_block

    Conical-tip ones ease measurement of center-to-center distances between hole centers. A stack of gauge blocks with external caliper-jaw accessories, all clamped together, acts as a quickly assembled custom-size go or no-go gauge. A special gauge block stone that cannot damage the surface is used to remove nicks and burrs to maintain ...

  9. Robot calibration - Wikipedia

    en.wikipedia.org/wiki/Robot_calibration

    Robot calibration is a process used to improve the accuracy of robots, particularly industrial robots which are highly repeatable but not accurate. Robot calibration is the process of identifying certain parameters in the kinematic structure of an industrial robot, such as the relative position of robot links.
