Definition

Diese Klassifikationsstelle umfasst:

(Für diese Definition ist die deutsche Übersetzung noch nicht abgeschlossen)

Guiding a pattern recognition process or device to a specific region of an image where the pattern recognition algorithm is to be applied, e.g. using fiducial markers.

The use of reference points in images, e.g. patterns having unique combinations of colours or other image properties, which make them useful for guiding a pattern recognition process.

Examples

Bildreferenz:G06V0010220000_0

A fiducial marker placed in the centre of an object is used for its object detection and recognition.

Bildreferenz:G06V0010220000_1

Bildreferenz:G06V0010220000_2

A pattern present on a marker gives additional information about the scene to be recognised.

fiducial marker fiducial markers	a fiducial marker is an image element which is explicitly designed for serving as a visual landmark point. A fiducial marker can be as simple as a set of lines forming crosshairs or a rectangle, but it can also be a more elaborate pattern such as an augmented reality tag, which additionally conveys information encoded as a two-dimensional barcode. Fiducial markers generally provide information about the position and, often, the orientation or the three-dimensional arrangement of objects in images. Additionally, they can comprise unique identifiers to support the recognition process. Fiducial markers are designed for being easily distinguishable from other image elements; therefore, they commonly have sharp image contrasts (e.g. by limiting their colours to black and white), and they are often designed to generate sharp peaks in the frequency space, allowing them to be easily recognisable by a two-dimensional Fourier transform. Commonly known fiducial markers are those defined by the augmented reality toolkit (ARToolKit).
