  • Patent number: 7145647
    Abstract: A system for measurement of spatial coordinates comprising a probing tool and a main measuring unit, wherein said probing tool comprises a reflective object element, observation mechanism located in a known position and orientation relative to said reflective object element and capable of observing targets; and wherein said main measuring unit comprises a distance measuring device capable of measuring a distance from said device to said reflective object element; a mechanism constructed and adapted to direct a measuring beam from said distance measuring device to said reflective object element; a direction determining mechanism constructed and adapted to determine a direction of a measuring beam; at least two targets located in known positions relative to said distance measuring device, whereby the orientation of said reflective object element can be determined from observations of said targets by said observation mechanism.

  • Patent number: 6166809
    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
