Patent ID: 8649598

Claim:
A method for determining a three-dimensional representation (V) of an object (O) using a sequence of cross-section images (X 0 . . . X m ) of the object (O) in a cross-section plane(P), each cross-section image (X 0 . . . X m ) having been taken at a respective moment (t 0 . . . t m ) of image capture, of the type comprising: for each cross-section image (X k ), determining theposition of the object (O) in relation to the cross-section plane(P) at the moment (t k ) the cross-section image (X k ) is captured, determining a three-dimensional representation (V) of the object (O) using cross-section images (X 0 . . . X m ) and positions of the object (O) in relation to the cross-section plane (P) at each moment of image capture (t 0 . . . t m ), the positions of the object(O) in relation to the cross-section plane (P) being determined using the cross-section images (X 0 . . . X m ), the method being characterized in that the object (O) has a movement in relation to the cross-section plane (P) made up, on one hand, of a regular movement defined by regular movement parameters (L, τ) and, on the other hand, a sequence of displacements (T 1 . . . T m ) disrupting the object between the moment (t k ) the cross-section image (X k ) is captured and the following moment(t k+1 ) of image (X k+1 ) capture, the disrupting displacements (T 1 . . . T m ) being disrupting translations, of variable direction and value, the determination of the positions of the object (O) in relation to the cross-section plane (P) comprises the determination of the sequence of disrupting displacements (T 1 . . . T m ) using the cross-section images (X 0 . . . X m ), the regular movement being a rotational movement defined by the following movement parameters: a fixed axis of rotation (L) and a constant angular speed (τ) determining the positions of the object (O) in relation to the cross-section plane (P) comprises determining at least part of the regular movement parameters (L, τ) using the cross-section images (X 0 . . . X m ).
