Process for the approach to an oriented relative position between a camera or scanning device and a dental assistance element

Process for an approach to an oriented relative position between a camera or scanning device and a dental assistance element (10), for recording the dental assistance element (10) comprising

• wherein the dental assistance element (10) comprises a miniature shade guide,
• wherein there is a mark (4) attached to the dental assistance element (10), and/or wherein at least one part of the dental assistance element (10) is used as a mark (4),
• wherein inside the camera or inside the scanning device or inside a memory for the camera or inside a memory for the scanning device, a stencil (6) which is congruent with or mathematically similar to the mark (4) or to the at least one part of the dental assistance element (10) is or are stored as a virtual image or characterising features of the mark (4) or at least one part of the dental assistance element (10) is stored, with relation to the distances of points from the stencil (6) and the mark (4) or the at least one part of the dental assistance element and/or an angle between lines and/or the positions of points and lines and/or the color values of points, and
• wherein for the approach to the oriented relative position between the camera or scanning device and the dental assistance element, a modification of the degree of coverage of the stencil (6) with the mark (4) or the at least one part of the dental assistance element (10) is detected and/or the degree of coverage and/or the modification of the degree of coverage is signalled, or wherein the approach to the oriented relative position between the camera or scanning device and the dental assistance element based on the stored features, the features of the mark (4) or the at least one part of the dental assistance element (10) are searched, wherein during the search, an identification of at least one of the features is detected and signalled.
