Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

      DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

    In the test environment test bed of the present invention, the inspection environment is constructed so that the existing scan data and the corrected finished data can be compared at a glance by utilizing the Unreal engine 4,

In order to obtain precise color information of the sculpture, accurate color codes are developed and a verification method for the color code change algorithm according to the reflection of light by material is constructed.

 In addition, it is possible to fix the light to a fixed position and to change it to various positions, and it is possible to confirm the reflection characteristic and the color distribution according to the light source by rotating the scan original and the correction result,

In addition, a variety of interactions and user interfaces are possible, and a checker process is provided to the examinee, and instantaneous digital contents of the contents can be determined.

It is also possible to move from one space to each verification environment and use Unreal engine 4's Change map blueprint to implement easy movement from one large virtual space to each verification space, By constructing digital contents contents, it is possible to easily carry out the inspection process,

In addition, since the algorithm for finding the original color of the object having the color and texture damaged over time is developed and verified by the verification method of the original color and texture traceback system,

       Therefore. When examining the test contents by contents of administrative contents which provide inspection process to examinees and judge pass / fail of instant digital contents contents,

The first step (10) is to run the colorimetric engine:

While loading .obj, scan uv along the photo plane corresponding to the respective scan planes of the front, back, left, right, flat, The second step (11) for verifying and checking the correction result by the car is:

The third step (12) to install on the test table bad by the contents of the administrative museum:

A fourth step (13) of verifying the corrected result according to the sensible digital evaluation list by combining the scan uv load and the photo uv load of the second step (11) with the sensed digital evaluation list;

A fifth step (14) of performing a complementary operation when the test procedure of the fourth step (13) fails;

A sixth step (15) of passing through the inspection process by testing all the inspection items related to the shape conformity, the shape accuracy, and the color correction; .

As shown in FIG. 9, since the inspection object is inspected for a delivery object in the form of a 3D display (refer to FIG. 2 to FIG. 4)

     The evaluation list of the realistic digital contents contents check the matters related to the shape and the color correction

  As for the inspection items related to the shape, as shown in FIG. 6, the inspection of the shape conformance is performed based on the test for determining an arbitrary point tolerance error, so that the error value of each arbitrary point can be stored. Point by specifying an Error field,

The tangent error measure was used as a criterion in relation to the shape conformity (see FIGS. 7 and 8), and the tangent error scale was calculated based on the difference between the tangent vectors for the vertices v1 and v2 For the shape model, the data file of the neighboring triangle list is searched for the node contacts of the contents of the stationary contents constituting the surface, and a cone triangle is constructed. The surface error is obtained by converting the data to the shape precision value. However,

If you look at the test for color correction items,

Adjusting a position of the map, correcting (concatenating) the partial boundary,

 A step of correcting the high ligt (light) portion, a step of correcting color / contrast / lightness / saturation, and a step of correcting the whole and partial brightness of the map for each stroke object Turntable 113 and the stroked object contents 114 inspected in the Turntable 113 (refer to FIG. 4) are used to perform a verification test .

    In addition, the standard inspection system is manufactured by Unreal Engine. When the inspection of the completed contents of the administrative contents is performed, the test room is formed as the environment that has the least influence on the surrounding environment. The environment of the peripheral wall of the test bed 112 is formed as a white wall.

Also, since the overall lighting environment 110 provides a real light effect on the Unreal engine, this effect is more realistic than other rendering software.

The surrounding illumination of the test bed 112 of the test room is provided with the point lighting 111 separately for the entire illumination environment 110 and the test bed 112 to check the reflection characteristics and the color distribution according to the light source, It is to examine the administrative object.

4). The test bed 112 is arranged to test the primary corrected stroke contents, the secondary corrected stroke contents, and the third corrected stroke contents, respectively. When approaching for inspection (see FIG. 2), the movable object 114 rotates automatically because the turnable tentable 113 is configured so that the inspector can examine the object more precisely.

In addition, a plurality of interactors and a user interface are made possible so that the inspector can collectively check the state of the obstacle 114 by operating the keyboard and the mouse in the inspection system.

This provides the inspector with a verification process and can determine the pass / fail of instant digital content.

       In addition, by using Unreal engine 4, we can verify inspection contents by constructing inspection environment to compare the existing scan data and the corrected result data at a glance,

 By moving from one space to each verification environment and using Unreal engine 4's Change map blueprint, it is possible to easily move from one large virtual space to each verification space, By checking the contents of the museum contents, it is possible to easily carry out the inspection process.

In addition, an algorithm for finding the original color of a stroke object whose color and texture have been damaged over time is developed and validated by a verification method of the original color and texture traceback system.

In order to check the accuracy of the color, the scanned Red color (Ra), the scanned Green color (Ga), and the scanned Blue color (Ba) are respectively corrected by first to third order (refer to FIG. 5) (Rb), the corrected absolute color (Gb), and the corrected absolute color (Blue) (Bb).

One). Scanned red color (Ra) of static object ▶ Corrected absolute color Red color (Rb),

2). Scanned green color (Ga) of static object ▶ Corrected absolute color Green color (Gb),

3). Scanned blue color (Ba) of stationary object ▶ Corrected absolute primary color Blue color (Bb),
