Abstract
A method is disclosed for evaluating data representing the three-dimensional shape of at least a portion of the surface of a human being or animal, in the following referred to as 3D data, wherein 3D data of at least two data sets, each representing the three-dimensional shape of at least a portion of the surface of a human being or animal and each taken from a database of three-dimensional shapes, in the following referred to as 3D data sets. Auxiliary devices may be manufactured based on 3D data stored in the data base, and a method for obtaining the 3D data to be stored in the data base is also disclosed.
Claims9
A method for evaluating data representing the three-dimensional shape of at least a portion of a surface of a human being or animal, in the following referred to as three-dimensional (3D) data, the method comprising:
- obtaining three-dimensional (3D) data of at least two 3D data sets using an optical recording device that is adapted and configured for taking images containing three-dimensional data of the surface, wherein the optical recording device includes a 3D camera that is adapted to record 3D images and an inertial measurement unit that is adapted to detect movement and orientation of the optical recording device in three-dimensional space;
- moving the optical recording device along the surface while taking a plurality of 3D images;
- detecting the movement and orientation of the optical recording device in the three-dimensional space with the inertial measurement unit;
- determining a three-dimensional shape of the surface by taking into account a temporal correlation of the data acquired by the inertial measurement unit with the 3D data provided by the optical recording device;
- and
- providing detection data representing the determined three-dimensional shape of the surface,
- wherein the 3D data of the at least two 3D data sets, each representing the three-dimensional shape of at least a portion of the surface of a human being or animal and each taken from a database of three-dimensional shapes, are evaluated,
- wherein the at least two 3D data sets are 3D data sets obtained for different human beings or animals to compare the three-dimensional shapes of the different human beings or animals.
