ABSTRACT:
A method for reading the shape of any elastically deformable article uses a contact feeler to follow the shape to be read. The contact feeler is applied to the article with a force of particular value adapted to cause localized deformation of the article and the coordinates of the contact feeler are noted at the relevant time. Two successive coordinate readings are systematically carried out, one with a first non-zero set point value of the contact feeler application force and the other with a second non-zero set point value of the application force different than the first set point value. The coordinates for a zero set point value of the contact feeler application force are deduced mathematically from the two coordinate readings.
