摘要:
An apparatus for pointing spatial coordinates, comprising a movable hand-held probe, having a pointing tip, and a portable base unit provided with a rotatably supported elongated arm, wherein the hand-held probe connects to the portable base unit by means of a cord or a wire via the elongated arm and wherein the base unit is provided with sensors for measuring length or a change in length of the cord or the wire and rotation of the arm in at least one degree of freedom, and computer-controlled processing means for processing measuring signals delivered by the sensors into position data of the hand-held probe.
摘要:
In an apparatus for measuring spatial co-ordinates of an object, which apparatus comprises a portable base-unit (4) and a movable hand-held probe (50) having a front tip portion (164) for touching the object and a radiatlon-reflectlve rear portion (166), the base unit includes a time-of flight measuring system (25) for measuring the distance (z) between the probe (50) and the base-unit, and optical orientation-sensing means to determine the orientation of the probe (50) for determining the distance to the object. In a time of a-of-fllght measuring method, the time is measured in which a pulse of optical radiation energy, generated by a source of optical radiation (32) travels to a detector (48) after reflection of the pulse by the probe (50). The optical pulse is generated with a pulse repetition dependent on the distance (z), and the pulse repetition Is measured.

摘要:
A method of determining a target spatial coordinate using an apparatus comprising a movable hand-held probe, having a body and a pointing element for pointing the target spatial coordinate, and a portable base unit provided with line-of-sight distance coupling means, wherein the hand-held probe is coupled to the base unit by said line-of-sight distance coupling means, coupled to the body at an attachment point, and wherein the base unit is provided with sensors providing measuring signals for measuring length or a change in length of the line-of-sight distance coupling means and rotation of said line-of-sight distance coupling means in at least one degree of freedom. Computer-controlled processing means are arranged for processing measuring signals. The method further comprising retrieving measuring signals wherein the target spatial coordinate is appointed from different orientations of the hand-held probe, and determining the target spatial coordinate from the measuring signals.
