Abstract (en)
[origin: FR2910646A1] The method involves acquiring a curve characteristic (ALPHA100) of a reference lens (100), and determining reference projection distance (R1) between a projection (MO1) of a reference anchoring point (O1) of the lens and a projection (MC1) of a reference drilling point (C1) of a target drilling hole (110). Tri-dimensional distance between the lens anchoring point and the hole drilling point is calculated according to the lens curve characteristic and the determined distance. A position of the hole on a target correction lens is determined based on the tri-dimensional distance.
