Abstract

A survey apparatus includes a guide light emitting optical system emitting a fan-like visible laser light elongated in upward and downward directions as a guide light, a cylindrical part having a scanning optical system searching a corner reflector provided on a survey pole and a ranging optical system measuring a distance to the corner reflector, a driving part rotating the cylindrical part about a vertical axis in a horizontal direction and rotating the cylindrical part about a horizontal axis, and an angle measurement part measuring a direction of the cylindrical part. The guide light emitting optical system is rotated about the vertical axis in a horizontal direction integrally with the cylindrical part.

First claim

What is claimed is:

1. A survey system comprising:
a guide light emitting optical system that emits a fan-like visible laser light elongated in upward and downward directions as a guide light;
a cylindrical part that has a scanning optical system that searches a corner reflector provided on a survey pole and a ranging optical system that measures a distance to the corner reflector;
a driving part that rotates the cylindrical part about a vertical axis in a horizontal direction and that rotates the cylindrical part about a horizontal axis;
an angle measurement part that measures a direction of the cylindrical part;
a first storage part to store the distance to the corner reflector obtained by the ranging optical system and the direction of the cylindrical part as measurement data;
a control circuit that controls the driving part, the scanning optical system, and the ranging optical system; and
a transceiver part that transmits the measurement data stored in the first storage part to a mobile wireless transceiver at a side of the survey pole, wherein
the guide light emitting optical system is rotated about the vertical axis in a horizontal direction together with the cylindrical part;
the control circuit controls the driving part to rotate the cylindrical part toward a next setting point;
the transceiver part transmits the measurement data stored in the first storage part to the mobile wireless transceiver; and
the mobile wireless transceiver includes
a second storage part that stores design data,
a display part that displays a setting map, and
a control part that calculates the measurement data to the corner reflector, which is obtained by the ranging optical system and the angle measurement part, using the design data from the cylindrical part to the next setting point,
wherein the control part obtains a distance and a direction from a current position of the corner reflector to the next setting point based on the calculated measurement data_and displays the direction and the distance from the current position of the corner reflector to the next setting point on a screen of the display part.

2. The survey system according to claim 1 , wherein
the cylindrical part has a first direction sensor and the mobile wireless transceiver has a second direction sensor, and
the control part of the mobile wireless transceiver relatively rotates the setting map such that the setting map to be displayed on the display part is matched with an actual direction based on a direction signal of the second direction sensor and the design data associated with an azimuth direction.

3. A mobile wireless transceiver used in the survey system according to claim 1 , wherein
the control part displays a forward display mark indicating a movement direction from a current position of the corner reflector to the next setting point on the display part.

4. A mobile wireless transceiver used for a survey pole comprising a post having a top portion; and an inverted cone like support locking part supported by user's hooking fingers on the top portion, the support locking part having an upper surface formed as a flat surface on which a mobile wireless transceiver transmitting and receiving information with a transceiver part of a survey apparatus is fixed, a retroreflective corner reflector being provided on a middle part of the post, and the survey pole being hanged up by its own weight,
the mobile wireless transceiver comprising:
a storage part that stores design data;
a display part that displays a setting map;
a direction sensor that detects a direction;
a camera part having a photographing optical system;
a transceiver part that transmits and receives data with the survey apparatus; and
a control part that controls the camera part and relatively rotates the setting map on the screen such that a positional relationship of actual setting points is matched with a positional relationship of setting points to be displayed on the screen based on a direction signal of a second direction sensor, wherein
the control part displays a movement displaying mark indicating a moving direction from a current position of the corner reflector to a next setting point on the display part.

5. The mobile wireless transceiver according to claim 4 , wherein the control part switches a mode from a map mode displaying the setting map to a photographing mode photographing an image when a distance from the current position of the corner reflector to the next setting point is a predetermined value or less.

6. The mobile wireless transceiver according to claim 5 , wherein the control part displays a setting point as a mark on the screen of the display part.

7. The mobile wireless transceiver according to claim 6 , wherein the control part displays a distance from the survey pole to a point where the setting is to be next performed as a numeric value and a direction on the screen of the display part when the mode is the photographing mode and the distance is less than the predetermined value and a constant value or more.
