Abstract
Method of measuring at least one dimension (L) of an object (1) having a first axis (2), the method including the use of a first optical system (11) including an optical sensor (111) and having a second optical axis (113), the measuring method including (i) obtaining at least one series of data from the optical sensor when the object is in movement relative to the first optical system, notably an angular movement of the first axis relative to the second axis and/or a movement of the object in rotation about the first axis and/or a movement of the object in translation along the second axis and (ii) processing the at least one series of data to quantify said at least one dimension.
