Patent ID: 7280226

Claim:
Method for enlarging the measuring volume of an optical measuring system with at least one camera ( 2 , 3 , 4 ) to determine the position of at least one point of an object ( 1 ) in relation to a base co-ordinate system, characterised in that, in order to determine the position of a point which is not situated within the field of vision of said camera ( 2 , 3 , 4 ), this camera ( 2 , 3 , 4 ) is moved in relation to a reference ( 7 ), having a fixed position in relation to said base co-ordinate system, towards a measuring position, so that said point comes within the field of vision of the camera ( 2 , 3 , 4 ), whereby the movement of the camera ( 2 , 3 , 4 ) in relation to said reference ( 7 ) is determined and the position of said point is perceived with said camera ( 2 , 3 , 4 ) in order to calculate its position in relation to said base co-ordinate system, taking into account the movement of the camera ( 2 , 3 , 4 ), and at least one part ( 12 ) of each of said reference organs ( 8 , 9 , 10 ) is rotated in relation to said fixed position, so that the reference points ( 13 , 14 , 15 ) thereof can be perceived by said camera ( 2 , 3 , 4 ).
