Patent ID: 7639866

Claim:
A radiographic imaging method for three-dimensional reconstruction, for calculating a three-dimensional model of at least one object to be imaged in a field of observation, said object having at least one characteristic portion, the method including the following steps: b1) estimating a confinement hexahedron of said characteristic portion of the object from at least one geometrical pattern visible in two two-dimensional radiographic images of the field of observation taken from a source having a position in two non-parallel image-taking directions, and from said position while taking the image; b2) calculating at least one estimator corresponding to at least one geometrical characteristic of the object on the basis of said confinement hexahedron, said estimator being an estimation of a height, width, depth, length, area or coordinate of the object c) providing an a priori knowledge base of the object comprising information associated with the three-dimensional shapes of objects of the same kind as the object to be imaged, enabling a geometrical characteristic for the model representing the object to be established from an estimator of a geometrical characteristic of the object; and d) calculating the three-dimensional shape of a model representing the object on the basis of said a priori knowledge base by establishing the geometrical characteristic for the model representing the object from the estimator.
