The present invention relates to a measurement target jig structure, and more specifically, it is capable of rotating 360 degrees, and it is possible to exchange the prism target and the sheet target to measure and correct both the prism mode and the sheet mode in the yard, To a target jig structure.

In general, instrument calibration is performed by specialized equipment such as a collimator.

FIG. 1 is a block diagram illustrating a calibration method of a conventional meter.

As shown in FIG. 1, a specialized company may be provided with a collimator 2 and a calibration system 3 for inspection or calibration of the measuring instrument 1.

Inspection or calibration performed by these specialists takes several days to several weeks, so it is often difficult to carry out and therefore there is always a possibility of error within the calibration period.

Also, to minimize the error, some instruments perform a calibration every time the measurement is performed.

The most common calibration method used in measurement work is always in a constant position, using a milestone to know its exact coordinates, or using a bar of constant length.

When an instrument is developed in-house, the configuration of the self-calibration means corresponding to the self-developed product may be very difficult.

In addition, it may be affected by the field conditions and calibration of the instrument may be difficult. For example, it is not easy to use a milestone or a certain length of bar in a poor field environment. Therefore, there is a need for a method that can easily calibrate the instrument in the field.

In addition, the conventional distance correction apparatus is installed for a sheet target. In order to maintain and correct the traceability of the distance correction apparatus, the distance measurement apparatus and the prism are calibrated by a professional company.

However, conventionally, even if a distance measuring apparatus and a prism are calibrated using a distance measuring apparatus and a prism that have been calibrated by a specialized company, there is a problem that data reliability is lowered due to a different target by using a sheet target in the distance correcting apparatus and the field.
