Process for determining a three dimensional representation (V) of an object (O) from unasecuencia imaging section (X0 ... Xm) of the object (O) in a cutting plane (P), each image having been ensección (X0 ... Xn) taken at an instant of taking of view (t0 ... tm) respective, of the type comprising: - for each image section (Xk), the determination (200) of the object position ( O) with respect to the plane Decorte (P) at the instant (tk) making the sectional image (Xk), - determining (400) a three-dimensional representation (V) of the object (O) from the images in section (X0 ... Xm) and the positions of the object (O) with respect to the cutting plane (P) at each instant making view (t0 ... tm) procedure in which the positions of the object (O) with respect to the cutting plane (P) images section (X0 ... Xm) is determinanutilizando, - the method being characterized by the fact that, having the object (O) being one Stroke with respectoal to the cutting plane (P) compound, on one hand, for regular movement defined by a regulating demovimiento parameters (L, π) and, on the other hand, by a succession of movements of perturbations (T1 ... Tm) delobjeto between the instant (tk) making a sectional (Xk) and the instant (tk + 1) making the following (k + 1), being the displacement disturbance (T1 ... Tm) of Translaciones disturbance direction and valorvariables, determining (200) the positions of the object (O) with respect to the cutting plane (P) comprises ladeterminación (300) of the succession of displacements of disturbance (T1 ... Tm) using the sectional images (X0 ... Xm), and by the fact that the regular movement being a rotational movement defined by parámetrosde following movement: one constant fixed axis of rotation (L) and an angular velocity (π) , determining (200) delas positions of the object (O) with respect to the cutting plane (P ) Comprises determining (210, 300) of the menosuna of regular motion parameters (L, π) using the sectional images (X0 ... Xm).
