The present invention is an apparatus for scanning irregularities. In one embodiment of the present invention, an object to be scanned having a roughened surface is painted (10). Hereinafter, the protruded portion of the concavo-convex surface will be referred to as the embossed portion, and the depressed portion will be referred to as the depressed portion.

FIG. 4 is a view illustrating a camera applied to a scan module of an uneven surface scanning apparatus using an opaque fluid according to an exemplary embodiment of the present invention. FIG. 5 is a cross- And the line scanner is applied to the scan module of the uneven surface scan device.

4 and 5, an uneven surface scanning apparatus using an opaque fluid according to an embodiment of the present invention will be described.

4 and 5, an opaque fluid-based uneven surface scanning apparatus according to an embodiment of the present invention includes a substrate 110, a lapping film 120, a fluid 130, and a scan module 150, . ≪ / RTI >

The substrate 110 may be a transparent glass material. However, the material of the substrate 110 is not limited to glass, and any material can be used as long as it is a transparent material through which light such as a transparent synthetic resin can be transmitted.

The lapping film 120 is in direct contact with the uneven surface of the coating 10 and can be pressed by the coating 10. Therefore, the lapping film 120 may be a material that can be easily resiliently restored after being deformed by an external force such as thin vinyl, rubber, or synthetic resin.

For restoration of the lapping film 120, the lapping film 120 may be installed on the substrate 110 in a state where tensile force is applied in all directions. That is, before the lapping film 120 is installed on the substrate 110, the lapping film 120 may be pretensioned.

Alternatively, on both sides of the lapping film 120 for fast restoration of the lapping film 120, a device (not shown) may be provided to pull the lapping film 120 to both sides.

The opaque fluid 130 may be filled between the substrate 110 and the lapping film 120.

Therefore, when the lapping film 120 is pressed by the coating 10, the portion pressed by the embossed portion abuts the substrate 110, and the portion corresponding to the engraved portion is positioned at the recessed portion of the fluid 130 .

At this time, the surface of the lapping film 120 facing the substrate 110 may have a color contrast with the opaque liquid 130. For example, the opaque fluid 130 may be blue and the surface of the lapping film 120 facing the substrate 110 may be red. Alternatively, the opaque fluid 130 may be red, and the side of the lapping film 120 facing the substrate 110 may be green.

In addition, the outer surface of the lapping film 120 may be red to minimize contamination of the outer surface of the lapping film 120 by the embossing on the coating 10.

For this purpose, the lapping film 120 may have different colors on both sides, but may be opaque vinyl, rubber, synthetic resin, etc., both red on both sides, for ease of manufacturing.

An elastic layer 140 may be provided on the upper surface of the substrate 110. The elastic layer 140 may be a material such as rubber, vinyl, or synthetic resin that can be deformed by an external force. The elastic layer 140 may be made of a transparent material so that the scan module 150 located below the substrate 110 can take an image of the uneven surface of the paint 10.

The elastic layer 140 is pressed by the coating 10 together with the lapping film 120 so that the portion corresponding to the relief portion of the coating 10 is compressed and the lapping film 120 and the substrate 110) can be increased, so that a clearer image of the uneven surface can be obtained.

A scan module 150 for photographing the substrate 110 may be provided under the substrate 110. The scan module 150 can photograph the lower surface of the substrate 110 in a flat image. As shown in FIG. 4, the scan module 150 may be a camera that photographs an image of a bottom surface of the substrate 110 at a time. Alternatively, as shown in FIG. 5, the scan module 150 may be a line scanner that moves in one direction and scans an image of the bottom surface of the substrate 110.

Meanwhile, a load cell 160 may be provided under the substrate 110. The scan module 150 can automatically photograph the substrate 110 when a force greater than a preset value is applied to the load cell 160.

Alternatively, although not shown in the drawing, the uneven surface scanning apparatus using the opaque fluid of the present embodiment may further include a display unit (not shown) capable of realizing the image of the lower surface of the substrate 110 in real time. Thereby, the user can press the lapping film 120 with the coating 10 to check the image of the lower part of the substrate 110 in real time through the display unit (not shown), and adjust the force so that a clear coating 10 image appears And when the desired image is displayed, the scan module 150 may store the image.

Therefore, the user can obtain an image of a clear uneven surface.

However, the above description is only one example, and the operation of the scan module 150 can be variously performed as needed.

According to the opaque surface scanning apparatus using the opaque fluid of this embodiment, since the configuration is very simple, it can be downsized and lightened, and can be used as a dedicated scanner for painting in banks and public offices. .

FIG. 6 is a view showing a state in which an opaque surface scanning apparatus using an opaque fluid according to an embodiment of the present invention scans a surface of a coating. FIG.

Hereinafter, the operation of the opaque surface scanning apparatus using opaque fluid according to an embodiment of the present invention will be described with reference to FIG.

First, the user can press the lapping film 120 with the coating 10.

6, the lapping film 120 is pressed by the coating 10 so that the portion of the coating 10 corresponding to the relief portion of the coating 10 abuts against the elastic layer 140, Opaque fluid 130 may be present at the depressed portion.

At this time, the elastic layer 140 located on the upper side of the substrate 110 is pressurized and pressed by the embossed portion, so that the adhesion of the portion of the lapping film 120 corresponding to the embossed portion can be enhanced.

In this embodiment, it is assumed that the opaque fluid 130 is blue and the surface of the lapping film 120 facing the substrate 110 is red.

Therefore, when the substrate 110 is viewed from the lower surface of the substrate 110, the portion pressed by the embossed portion of the lapping film 120 comes into contact with the transparent elastic layer 140, Portion will appear blue because the opaque fluid 130 is present at the depressed portion.

Thus, when the substrate 110 is viewed from the lower surface of the substrate 110, the embossed portion of the coating 10 may appear in red and the engraved portion may appear in blue, such as when a paint 10 is formed on a paper.

At this time, the load cell 160 measures the magnitude of the force for pressing the substrate 110 with the coating 10, and when the measured force is not less than a preset value, the scan module 150 is operated to move the substrate 110 Can be photographed.

Alternatively, the user presses the substrate 110 with the coating 10, observes the image of the lower surface of the substrate 110 in real time through a display unit (not shown), and displays the image It is possible to input a command to store the current image through an input unit provided separately.

7 is a view showing an image of the uneven surface of the coating obtained by the irregular surface scanning apparatus using opaque fluid according to an embodiment of the present invention.

Through the above process, as shown in FIG. 7, the shape of the uneven surface of the paint 10 can be obtained as a clear two-dimensional image.

In the present embodiment, the object to be scanned having the irregular surface has been described as the coating 10, but the irregular surface scanning apparatus using the opaque fluid of the present embodiment is applicable not only to the painting 10 but also to the surface of various objects Can be photographed.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
