[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a position measuring method, and more particularly to a position measuring method used for positioning civil engineering and construction works.

[0002]

2. Description of the Related Art As a conventional surveying method of this kind, for example,
An operator stands with a target such as a prism near the target position, and another operator collimates the target with a survey instrument from a point separated by a distance. When there is a difference between the collimation value and the target position, the collimator instructs the worker having the target to move the target, and then collimates again.

Thus, the final target position is finalized through steps such as repetition of measurement and movement and position calculation.

[0004]

As described above, according to the conventional surveying method, two or more workers form a group to repeatedly perform collimation and movement, and then, through a means such as position calculation, a final measurement is performed. Positioning is performed. Therefore, a large amount of manpower and time are required for the surveying work, and the measurement accuracy and the operating amount vary due to factors such as the skill level of the worker and the working environment.

Therefore, there arises a technical problem to be solved so that a small number of people can perform high-precision survey in a short time without being affected by various conditions. It aims to solve problems.
