Method for monitoring and adjusting the position of an object under optical observation for imaging

摘要

To image a surface of an object more efficiently using automatic positioning of the object with respect to the optical axis of a camera while keeping the surface of the object at a predetermined angular orientation with respect to the optical axis, a general shape of the object is first measured and a mathematical function approximating the surface is determined. Relative displacements and orientations for an imaging path are then calculated and the object is manipulated along the imaging path while being imaged with the surface of the object being at the predetermined angular orientation. The speed and accuracy of surface imaging is improved.
