Description

A 3D scanning system {System for 3D scan}

The present invention relates to a three-dimensional scanning system, and more particularly, to a system for scanning a subject used in manufacturing a toy such as a figure.

In general, toys are often used for the purpose of children's play and scientific thinking.

The production of toys such as these figures was completed through the process of assembling the original (or mold, mold) through the human hand and then the hand, etc. In most cases, The cost is high), and the disadvantage is that the time and cost are remarkably high.

Also, in the case of online sales, it is almost impossible to order individual toys for the above reasons in most cases. In addition, since the number of materials and parts to be applied to toys such as figures can not be specified, it is one of the reasons why it is difficult to manufacture toys because there is no distinction of standardized parts and materials.

Because toy materials and parts such as figures are not only of that type but also of size and color, they have to be considered together.

On the other hand, in the production of toy products such as figures, it was formed into a uniform shape such as a shape of a famous character or an article shape matching with a specific theme (birthday, Christmas, etc.). For this purpose, the subject was photographed using a camera and the image of the photographed subject was used for toy production. However, since the 2D image is not stereoscopic, it is difficult to produce stereoscopic toys having the same feel as the subject.

It is a picture.

The scan system of the present invention may include a scan column 10, a scanner 20, and a 3D modeling terminal 30, as shown in FIG.

The scan column 10 is a columnar body arranged at a plurality of equal intervals so as to surround the subject. Although the scan column 10 is shown in the form of a cylinder in the drawing, it may have a columnar shape of various shapes such as a triangular column, a square column, an oblique column, and a hexagonal column. As shown in Fig. 2, the scan column 10 has guide grooves formed along the longitudinal direction of the column, and the scanner moving member can be vertically moved up and down along the guide grooves. Therefore, the scanner moving body is exposed to the outside through the guide groove.

1, the scanner basically moves up and down only, and the scan column 10 on which the scanner is mounted can be rotated around the subject along the circular rail. In the case of a structure that rotates along the circular rail, about three scanners can be mounted on the column body, and the number of the scanners provided in the various other scanning column bodies 10 is not limited.

The scanning column 10 has a scanner moving body capable of moving the scanner 20 upward and downward.

3, the scanner moving body includes a scanner body 140 to which the scanner 20 is coupled, a cylindrical body 130 to which the scanner body 140 is coupled, and a cylindrical body 130, And a scanner movement control unit (110) for controlling the amount of movement of the lifting member (120) up and down. Here, the ascending / descending member 120 can be realized by various means such as a guide rail. For example, the cylindrical body 130 can be lifted up and down along the guide rail by a motor.

4 shows an example of a perspective view of the scanner assembly 140 and the cylindrical body 130. The scanner assembly 140 and the cylindrical body 130 may have various configurations, .

Referring to FIG. 4, the scanner assembly 140 includes a scanner mounting bracket 141 and a mounting combiner 142, which are mounted on and fixed to the scanner 20.

The cylindrical body 130 is a body to which the scanner assembly 140 is coupled. The cylindrical body 130 is disposed at the upper end of the cylindrical body 131 and is in contact with the bracket 132, To be fixed to the cylindrical body 131.

The raising and lowering member 120 may be a rack gear, a limit switch, a sensing sensor, or the like. Alternatively, the raising and lowering member 120 may be raised or lowered by hydraulic pressure or air pressure to raise and lower the cylindrical body 130 vertically And various known rising and falling means can be used. Therefore, the scanner 20 may be located on the upper side as shown in Fig. 5 (a) by the ascending / descending member 120, or may be located on the lower side as shown in Fig. 5 (b).

The scanner 20 scans the subject while moving up and down by the scanner moving body. Here, the scan refers to taking a picture at a short cycle of ascending and descending, or taking a picture in units of a lattice in consideration of ascending and descending.

The scanner 20 transmits the scan image to the 3D modeling terminal 30 using the scan image according to the scan of the subject. The transmission to the 3D modeling terminal 30 may be in the form of a wired transmission or a wireless transmission. For example, wired communication methods such as Ethernet, universal serial bus, IEEE 1394, serial communication, and parallel communication may be used, and infrared communication, (Bluetooth), a home radio frequency (RF), and a wireless LAN may be used.

For reference, the scanner 20 may include a lens assembly, a filter, a photoelectric conversion module, and an analog / digital conversion module. The lens assembly may include a zoom lens, a focus lens, and a compensation lens.

The 3D modeling terminal 30 generates a 3D printing file using the scanned images received from the respective scanners 20. For this purpose, the 3D modeling terminal 30 has the same configuration as a typical web server in terms of hardware, and is implemented in various types of languages such as C, C ++, Java, Visual Basic, and Visual C And a program module that performs branch functions. In addition, it can be implemented using a web server program that is variously provided according to operating systems such as dos, window, linux, unix, and macintosh for general server hardware. Typical examples include a Web site used in a Windows environment, Internet Information Server (IIS), and CERN, NCSA, and APPACH used in a UNIX environment.

The 3D modeling terminal 30 combines the scan images received from the respective scanners 20 to generate 3D images. Various 3D image generation algorithms known in the art can be applied to generation of a 3D image by synthesis. Therefore, a maker who manufactures a toy such as a figure can produce a toy with reference to a 3D image, so that a more stereoscopic and realistic toy can be produced.

Further, the 3D modeling terminal 30 generates a 3D printing file using the generated 3D image. Here, the 3D printing file may be STL (Standard Triangulated Language) data as source data used when a 3D printer produces a 3D printing product.

For reference, the 2D printer moves only on the front and back (x axis) and left and right (y axis), but the 3D printer adds the up and down movement (z axis) I make it. 3D drawing data (STL data) can be produced using a 3D CAD (computer aided design), a 3D modeling program, a 3D scanner 20, or the like. Such data for the 3D printer can be produced through a 3D CAD (computer aided design), a 3D modeling program, or a 3D scanner 20. As is well known, the shape data creation step, shape data editing step, Lt; / RTI >

The shape data creation step is a step of extracting a three-dimensional shape of the object and creating three-dimensional shape data. Dimensional shape data through a 3D CAD (computer aided design), a 3D modeling program, or a 3D scanner 20. [ In order to create three-dimensional shape data, adjustment of the patch surface direction, deletion of unnecessary shells, compensation of gaps, reduction of patches, and smoothing processing of contour shape are performed, Preserves data in STL (Standard Triangulated Language) data format.

Next, the shape data editing step is a step of editing the three-dimensional shape data created by the modeling function. Here, the modeling function is a function provided by a commercially available three-dimensional image CAD software. It is possible to create a cross-section (including a partial cross-section), a plane, a curved surface, a primitive shape, , Adding symbols and letters, and adding marking codes.

Next, in the material type definition step, when a resin is used as a material to be used as a model material, a color, a light transmittance, a high softness, an X-ray transmittance, an ultrasonic susceptibility, a susceptibility to scintillation, Can be selected from a variety of resins capable of controlling the parameters of the resin. Further, the support material can be used as a model material for modeling. When two types of resins can be simultaneously injected as a model material, two resin materials of the model material can be selected and the blending ratios thereof (for example, resin A: resin B = 1: 3) can be defined. As described above, the user of the upload terminal can create 3D printer data through the shape data creation step, the shape data editing step, and the material type definition step.

On the other hand, when the scanner 20 is scrolled up and down, it is preferable that the ascending / descending range is determined in consideration of the height of the subject. This will shorten the scan time and allow for efficient scanning. This will be described in detail with reference to FIG.

FIG. 6 is a view illustrating a height of a subject through a height sensor according to an exemplary embodiment of the present invention. Referring to FIG.

As shown in Fig. 6, the scanner moving body is provided on the surface of the scanner coupling body 140 and includes a height detection sensor 143 for sensing the height of the subject. The height detection sensor 143 may be implemented by, for example, an infrared transmitter and an infrared receiver. The infrared transmitter periodically emits light and receives the reflected light through the infrared receiver so that the height of the subject can be detected. For example, as shown in FIG. 6 (a), the infrared light emitted from the height sensor 143 located at the upper side is not reflected but received by the object but is gradually lowered. When the infrared light is emitted, (b), the starting point at which the infrared ray begins to be reflected corresponds to the height of the object.

The scanner movement control unit 110 controls the ascending and descending movement amounts of the ascending and descending members 120 according to the height of the subject detected through the height detecting sensor 143. [ That is, the controller controls the elevating member 120 to rise up to the height of the object detected through the height detecting sensor 143.

In addition to the determination of the range of the scan amount using the sensor, there may be a method using a QR code. This will be described in detail with reference to FIG.

FIG. 7 is a further structural block diagram of a 3D scanner moving body according to an embodiment of the present invention.

The scanner moving body according to the present invention includes a scan amount database 150 provided in an internal space of a scan column 10 and assigned a rising and falling range of a lifting member 120 according to an identification number of a QR code, 10 may further include a QR code reader 160 for recognizing the QR code attached to the subject and reading the identification number.

The scanner movement control section 110 extracts the ascending and descending range of the ascending and descending member 120 assigned to the identification number read through the QR code reader 160 from the scan amount database 150 and outputs the extracted ascending descending member 120 The height of the lifting member 120 can be controlled.

Therefore, if the administrator attaches the QR code to each subject and then reads the image on the QR code reader provided on the surface of the scan column 10, the image can be ascended and descended only by the size of the subject, thereby enabling quick reading. In addition, when read to the QR code reader provided in one scan column 10, the read information is transferred to the other scan column 10 and controlled to be the same up / down amount.

The embodiments of the present invention described above are selected and presented in order to facilitate the understanding of those skilled in the art from a variety of possible examples. The technical idea of the present invention is not necessarily limited to or limited to these embodiments Various changes, modifications, and other equivalent embodiments are possible without departing from the spirit of the present invention.
