Method and device for enlarging the measurement volume of an optical measurement system
First Claim
1. 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).

Abstract
The invention concerns a method for enlarging the measuring volume of an optical measuring system and, on such a measuring system, at least one camera (2,3,4) to determine the position of at least one object (1) in relation to a base co-ordinate system, whereby, in order to measure 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 is situated 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 determine its position in relation to said base co-ordinate system, taking into account the movement of the camera (2,3,4).
