Abstract

A surveying instrument includes a pedestal provided with a guide light irradiation unit provided with a light source to irradiate with guide light indicating a collimation direction of the surveying instrument to an operator, a tracking optical system which locks a target, a ranging optical system which ranges a distance to the target, and a control circuit which calculates surveying data by a ranging result of the ranging optical system, and a transmitting and receiving unit which receives survey setting point data regarding a survey setting operation and sends the surveying data obtained by the control circuit.

First claim

What is claimed is:

1. A surveying instrument, comprising:
a pedestal provided with a guide light irradiation unit provided with a light source to irradiate with guide light indicating a collimation direction of the surveying instrument to an operator, a tracking optical system which locks a target, a ranging optical system which ranges a distance to the target, and a control circuit which calculates surveying data by a ranging result of the ranging optical system; and
a transmitting and receiving unit which receives survey setting point data regarding a survey setting operation and sends the surveying data obtained by the control circuit, wherein
the control circuit turns off the light source when the target is locked, rotates the pedestal such that an optical axis faces in a direction of a survey setting point when the locking of the target is released, stops the rotation of the pedestal, turns on the light source again, and performs searching and scanning with tracking light.

2. A surveying operation system, comprising:
a sending step of sending survey setting point data to the transmitting and receiving unit, which is provided on the side of an operator, by using the surveying instrument according to claim 1 ;
a rotation step of rotating the pedestal such the optical axis of the surveying instrument faces in a direction of the survey setting point based on the survey setting point data, and stopping the rotation;
a turning on step of turning on the light source of the guide light irradiation unit;
a turning off step of turning off the light source when the target on the side of the operator is locked by the tracking optical system;
a re-turning on step of turning on the light source again after rotating the pedestal in a direction of a next survey setting point designated by the survey setting point data, and stopping the rotation; and
a step of once turning off tracking light when the locking of the target is disturbed after the target is locked, turning on the light source again by directing again the optical axis in a direction of the survey setting point designated by the survey setting point data, and restarting searching and scanning with the tracking light.
