Abstract

A base station is installed in a predetermined area where a large number of target points are studded around the station. When the operator moves a mobile station around the base station, display means is provided for both or either of the base station that guides the operator and the mobile station, and a display screen of the display means displays 2 kinds of a Forward (foreground) mode and a Back (background) mode. In the Forward (foreground) mode, the display screen of the display means displays a landscape in a forward direction (opposite direction to the mobile station by 180° when seen from the base station) of the operator (mobile station) when the operator sees the base station from the current position of the mobile station, or from the next target point if the operator reaches the next target point. In the Back (backward) mode, the display screen of the display means displays the landscape in a backward direction (direction of the operator and the mobile station when seen from the base station) of the operator (mobile station) when the operator sees the base station from the current position of the mobile station, or from the next target point if the operator reaches the next target point. The relationship between the mobile station and the next target point is displayed on an imaginary landscape in an imaginary manner so that the operator can see the direction and distance for movement.

Claims

1. An operator guiding system that guides an operator when the operator moves with a mobile station around a base station installed, wherein

the base station is provided with imaging means and angle measurement means for detecting a photographing direction of the imaging means,

the mobile station is provided with display means, and

a display screen of the display means provided for the mobile station displays a landscape seen from a predetermined position in a direction of the base station, based on landscape data obtained by the imaging means and the angle measurement means provided for the base station.

3. The operator guiding system according to any one of claims 1 and 2, wherein

the predetermined position is positional coordinates of the next target point in previously decided construction plan data.

4. The operator guiding system according to any one of claims 1 to 3, wherein

a target line is displayed at a horizontal angle position corresponding to a direction where the base station is collimated from the next target point, or a direction making 180°

with the direction where the base station is collimated, on the landscape data.

5. The operator guiding system according to any one of claims 1 and 2, wherein

the predetermined position is a current position of the mobile station, which has been measured by the angle measurement means and distance measurement means in the base station.

6. The operator guiding system according to any one of claims 1 to 5, wherein

a collimation line is displayed from the current position on the landscape data in a collimation direction of the base station.

7. The operator guiding system according to claim 6, wherein

a landscape is displayed with a target line arranged at the center.

8. The operator guiding system according to claim 7, wherein

the target line is displayed in the same image as the one where the collimation line is displayed.

9. The operator guiding system according to claim 8, wherein

an arrow is displayed in a direction from the collimation line to the target line.

11. The operator guiding system according to any one of claims 1 to 10, wherein

the display screen of the display means provided for the mobile station displays scales of horizontal angles.

12. The operator guiding system according to any one of claims 1 to 11, wherein

the display screen of the display means provided for the mobile station displays scales of distance.

13. The operator guiding system according to any one of claims 1 to 12, wherein

the landscape data in which a predetermined point on the photographed image data is associated with three-dimensional coordinates is created.

15. The operator guiding system according to any one of claims 1 to 14, wherein

positional coordinates of the target point on the construction plan data are associated with positional coordinates on the landscape data to display the target point on the landscape data.

18. The operator guiding system according to any one of claims 1 to 17, wherein

the relative positional relation among the base station, the current position of the mobile station, and the next target point is artificially displayed.

21. The operator guiding system according to any one of claims 1 to 20, wherein

a case where the next target point is in a direction of the base station seen from the mobile station is defined as a foreground mode, a case where the next target point is in the opposite direction to the base station is defined as a background mode, and the foreground mode and the background mode are automatically switched.

22. The operator guiding system according to any one of claims 1 to 21, wherein

a height of the next target point from the current position is displayed.

23. The operator guiding system according to any one of claims 1 to 22, wherein

data is transmitted between the mobile station and the base station via communication means.

24. The operator guiding system according to any one of claims 1 to 23, wherein

the operator is capable of selecting the next target point from a plurality of target points.

25. The operator guiding system according to any one of claims 1 to 24, wherein

the landscape displayed is arbitrarily scrollable.

26. The operator guiding system according to any one of claims 1 to 25, wherein

when coordinates data is synthesized with photographed image data, a position h in a vertical directions, which uses a position corresponding to a level line on the image data as a reference, is found by the expression:

h=Hf/L

where L is distance data of the coordinates data, H is a machine height and f is a focal distance of the imaging means.

27. The operator guiding system according to any one of claims 1 to 21, wherein

the operator is capable of arbitrarily selecting any one of the foreground mode and the background mode.
