Abstract:
1. A method of detecting and for high-resolution digitizing of the 3D shape of an object, by photogrammetry using a multitude of point markers on said object, comprising the steps of: applying at least two area markers on the surface of the object, each of said area markers having a surface with a characteristic optical configuration different from the other area markers; providing a plurality of said point markers in each area marker, whereby said characteristic optical configuration of said area markers forms a background for the point markers; taking a plurality of photogrammetric images of the object from respective different views; performing an image processing of the images, in which performing a photogrammetric evaluation process for determining the 3D shape of the object using the said 2D coordinates of the multitude of associated point markers.
