Abstract:
A system and method for performing an optical tracking operation computes a translated movement value of a displacement values using a relationship between a reference displacement value derived using a reference surface and a corresponding displacement value using a target surface. The displacement value is produced using image correlation by optically sensing the target surface. The translated movement value is used for the optical tracking operation.
