摘要： A method and apparatus for determining the position of a plane of symmetry of a three-dimensional object from at least two two-dimensional mappings, wherein the mappings are obtained from different directions. At least one characteristic line of the three-dimensional object is determined in one of the two-dimensional mappings, and at least one of the two two-dimensional mappings is morphed. The at least one characteristic line is transferred onto the other two-dimensional mapping, and the characteristic lines from the two-dimensional mappings are back-projected to obtain a three-dimensional curve corresponding to the characteristic lines. A plane of symmetry of the object is ascertained from the course of the three-dimensional curve.

摘要： A method for determining a three-dimensional form of a body from two-dimensional projection images includes producing at least one projection image of the body and producing corresponding model projection images from a generic model of the body. The body projection images and the model can be input into a computer-assisted processing unit and the generic model can be adjusted to the body by comparing image contents of the body projection images with the model projections images at a two-dimensional level only. The three-dimensional form of the body can be determined from the adjusted generic model.
