Video Measurement System VM-17

VM-17 with active illuminated target board. Range up to 130 m, depends on diameter of pipe and dimensions of target.

A pilot pipe is pressed through the earth by the ground displacement method. The control adjustment is carried out quite simply by the inclined face of the control head. The inclinaton is related to the control axis of the target board. The arrangement of the target board places the all-important control axis in the centre. The target board is observed with a theodolite. A CCD camera transmits the picture to the monitor. Deviations from the target axis can be seen immediately and are corrected by turning the pilot pipe. The rotation is stopped as soon as the control axis is on the centre point of the telescope reticle. The height and direction are then corrected automatcally as driving proceeds, The target axis is reached when the centre of the target board coincides with the centre of the telescope reticle.

The VM-17 is based on a theodolite with an automatic compensator and horizontal and vertical fine motion screw and clamp. You can carry out remotely the focusing of the telescope with the monitor MF-03. The magnification and focusing of the reticle image is done manually at the camera system. The power is supplied via the monitor.

Note: Monitor MF-03 needed!


  • Remote controlled focus
    Together with the monitor MF-03 the focus of the theodolite can be remotely controlled.

  • Zoom-Camera
    Image scale: at 100 m target distance 1 : 0.5 to 1 : 2, Standard devation: ± 10 mm/100 m

  • Alignment telescope
    The first solution for quick and accurate line transmission and monitoring. Use the good method of line orientation from bottom to top to your advantage.

  • Adjustable illuminated target board
    The illumination of the target board can be adjusted according to the environmental conditions at the monitor, which is e separately available .

  • Complementary accessories
    Specific monitors and LED-targets guarantee a perfect harmonized system.
