Abstract: A system for point-by-point measurement of spatial coordinates comprising: one or more opto-electronic cameras (7, 8) arranged for measuring spatial direction to point-shaped light sources; one or more rangefinders (11) for measuring distance and optionally direction to light-reflecting targets (19, 28); a touch tool (18) having a minimum of three point-shaped light giving means (21-25) in known local coordinates relative to a local tool-fixed coordinate system, one or more light-reflecting points or targets (28) for the laser rangefinder, and having a contact point (30) in known position relative to said local coordinate system; and data processor (2) designed to compute the spatial position and orientation of said touch tool (18) relative to said camera (7, 8) and rangefinder (11) on the basis of knowledge of the position of said light giving means (21-25) relative to the tool's contact point (30), the measured directions from the cameras (7, 8) to the individual light giving means (21-25), and measured dis

Abstract: A method and system for determining the position and/or orientation of a number of objects relative to each other. At least two cameras having electro-optical sensors are provided. A network of help reference points is established. The positions of some points in the network relative to each other can be known or they are determined using at least one of the cameras positioned in multiple arbitrary locations. The positions of some of the objects relative to each other, are determined based on the determined positions of some of the points in the network. The position of at least one of the objects is determined by holding a probing tool in contact with a point on the object, and obtaining measurement data from the probing tool using at least two of the cameras.
