A measurement method for thread parameters for a threaded object (), by means of a measurement device () defining a spatial reference system (X, Y, Z) incorporating an optical sensor () to retrieve the shape of the threaded object, and defining a spatial reference system (X', Y&#x2032;, Z&#x2032;), the measurement device () having a computer to assemble a first matrix that describes the quadratic form representing the threaded object in the spatial reference system (X, Y, Z), thus providing the relationship between the two spatial reference systems. The method comprises the steps of:
