Patent ID: 6876458

Claim:
A method for determining the absolute coordinates of an object ( 1 ) in which the method the object ( 1 ) is exposed to light ( 3 ) through a projection grid ( 2 ); the light ( 4 ) reflected by the object ( 1 ) is registered by a sensor ( 5 ); and the image picked up by the sensor ( 5 ) is evaluated, wherein the projection grid ( 2 ) comprises a first grid with a first grid vector (G 1 ), and a second grid with a second grid vector (G 2 ) which differs from said first grid vector, and the sensor ( 5 ) is arranged at a distance (b) from the projection grid ( 2 ) such that the projections (b x , b y ), of the base vector (b) leading from the first and from the second grids to the sensor ( 5 ), onto the associated grid vectors (G 1 , G 2 ) differ in size.
