The paper investigates the problem of computing the 3D orientation of a rigid body by analysing the focus data extracted from the images of a videomicroscope. ...
But the modelling stage is simplified, instead of performing a 3D modelling, a 1D modelling is achieved which enables the estimation of the 3D orientation of the object. ...
This paper investigates the tracking of rigid bodies in the images delivered by a high magnification videomicroscope, more precisely a solution is proposed for the estimation of the 3D orientation of a ...

The calibration is performed through a virtual pattern made by tracking a silicon micro part in the images of the scene. ...
The main image source is the photon videomicroscope whose features are the weakness of the depth-of-field and that of the field-of-view. ...
The third section states the experimental results obtained with a commercial videomicroscope (MZ16A from Leica) characterized by a motorized zoom and focus. ...
