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).
