1 is a schematic diagram illustrating an example of a configuration of a device 100 according to an embodiment.

Referring to FIG. 1 , a device 100 according to an embodiment may include a scanner 110 , a display 120 , and a processor 130 .

The scanner 110 according to an embodiment may acquire scan data of the object 200 . For example, the device 100 may further include a mechanical unit 140 capable of attaching and moving the object 200 (see FIG. 2 ), and the scanner 110 may include the object 200 attached to the mechanical unit 140 . ) may be captured to generate scan data of the object 200 for one scene. In an embodiment, the scan data may be implemented in various 3D image formats that may be vectorized through the display 120 .

In an embodiment, the object 200 may include a dental structure 210 . Here, the tooth structure 210 represents an artificial structure simulating the shape of a user's teeth, and may be, for example, a 3D printing structure formed based on 3D modeling data of the user's teeth.

The scanner 110 according to an embodiment may sequentially acquire a plurality of scan data of the object 200 over time. For example, the scanner 110 scans the tooth structure 210 moved by the mechanical unit 140 that translates or rotates in various preset positions, directions, or angles to sequentially scan a plurality of time-series indexed scan data. can be created with

In an embodiment, a plurality of scan data may be obtained for a plurality of angles with respect to the object 200 . For example, as shown in FIG. 2 , the instrument unit 140 may be rotated at a predetermined angle about one or more predetermined axes, and the scanner 110 may be rotated with the dental structure 210 by the instrument unit 140 . ) to generate scan data for the scene, and such rotation and imaging can be performed according to a preset scan scenario (e.g., rotation is repeated up to 360 degrees at an angle of 30 degrees about the first axis) or user input. It is possible to repeatedly generate a plurality of scan data for each scene having a different angle with respect to the dental structure 210 .

In another embodiment, the plurality of scan data is obtained for a plurality of distances from the scanner 110 to the object 200 , or is included in the device 100 and generated by the lighting unit generating a light source toward the object 200 . It may be obtained for a plurality of illuminances. For example, the scanner 110 repeats imaging of the dental structure 210 moved to have a different distance from the scanner 110 in a state rotated at the same angle by the mechanical unit 140, or rotates at the same angle. A plurality of time-series indexed scan data may be sequentially generated by repeating imaging of the dental structure 210 illuminated with different illuminance by the lighting unit in the state of being in the same state.

In one embodiment, the scanner 110 may be implemented through one or more camera modules or scanning modules, for example, may be implemented as a 3D scanner to generate 3D scan data for each scene. In an embodiment, the scanner 110 may generate scan data by capturing image data acquired while photographing the object 200 for each scene, or may generate scan data by repeating imaging of the object 200 . have. In an embodiment, the scanner 110 may be fixed to one end of the device 100 and installed in the mechanical unit 140 to face the center of one surface to which the object 200 is attached.

The display 120 according to an embodiment may display an image of the object 200 in which a plurality of scan data are distinguished from each other and displayed overlappingly. In an embodiment, the image may include a 3D image, and may be generated based on one or more scan data acquired with respect to the object 200 up to the most recent time point.

For example, as shown in FIG. 3 , when the first scan data 310 for the dental structure 210 is obtained, the display 120 may visualize a 3D image in which the first scan data 310 is displayed. have. In addition, when the second scan data 320 for the rotated dental structure 210 is obtained as the dental structure 210 is rotated by the mechanical unit 140 at a preset angle, the display 120 obtains the first scan data Based on 310 , the 3D image may be updated by processing the image so that the area where the second scan data 320 overlaps or the newly added area is visually distinguished. Thereafter, the display 120 repeats the above-described operation as the third scan data to the Nth scan data (N is a natural number) are sequentially acquired, so that a region overlapping with the previously acquired scan data is distinguished from the 3D image can be updated.

The display 120 according to the first embodiment may display a plurality of scan data with mutually different brightness. For example, as shown in FIG. 3 , when the display 120 displays the second scan data 320 superimposed on the first scan data 310, the brightness of the overlapping area is adjusted differently according to the setting. can be visualized.

In the first embodiment, the magnitude of the brightness corresponding to the plurality of scan data sequentially acquired over time may increase over time. For example, the display 120 may increase the brightness of the overlapping area in the first scan data 310 and the second scan data 320 by a preset ratio to a preset upper limit value or less, and thus the scan data As the number of overlapping areas of the overlapping region increases, it can be visualized to gradually brighten up to the upper limit in proportion to it.

Accordingly, in the process of rotating and scanning the object 200 at various angles, the device 100 visualizes in real time the part being effectively photographed through the scan at the current angle, so that the administrator can select the part requiring image supplementation. It can help you to check it intuitively.

The display 120 according to the second embodiment may display a plurality of scan data in mutually different colors. For example, when displaying the second scan data 320 superimposed on the first scan data 310 , the display 120 may visualize the overlapped region by differently adjusting the color according to the setting.

In the second embodiment, colors corresponding to a plurality of scan data sequentially acquired over time may be updated from a color adjacent to the first color to a color adjacent to the second color over time. For example, the display 120 may change the color of the overlapping area in the first scan data 310 and the second scan data 320 from a color adjacent to yellow to a color adjacent to red by a set change amount, , it can be visualized from yellow to red gradually as the number of overlapping regions overlapped between scan data increases.

Accordingly, the device 100 sets the final color when each scene of the object 200 is scanned, and provides a visual effect in which the color of the overlapping area between the scan data gradually changes to the final color. have.

The display 120 according to the third embodiment may display a plurality of scan data with mutually different transparency. For example, when displaying the second scan data 320 superimposed on the first scan data 310 , the display 120 may visualize the overlapped area by differently adjusting the degree of transparency according to settings.

In the third exemplary embodiment, a level of transparency corresponding to a plurality of scan data sequentially acquired over time may decrease over time. For example, the display 120 may reduce the transparency of the overlapping region in the first scan data 310 and the second scan data 320 by a preset ratio to a preset lower limit value or more. As the overlapping number of the overlapping region increases, it can be visualized to gradually become opaque up to the lower limit in proportion to it.

In the third embodiment, the transparency corresponding to the initially acquired scan data may be less than a preset value. For example, as shown in FIG. 3 , the first scan data 310 corresponding to the initial image may be visualized as opaque by setting the transparency to 0, and the second scan data 320 obtained thereafter are opaque. The first scan data 310 to be displayed can be overlapped and displayed in a way that transparently overwrites the first scan data 310 with a transparency first value (eg 50), and in the same way, the third scan data corresponding to images acquired thereafter The N-th scan data may also be overlapped and displayed in such a way that the opaquely displayed first scan data 310 is transparently overwritten with a preset first value or a second value larger than the first value.

In the third embodiment, the level of transparency corresponding to the plurality of scan data sequentially acquired after the second time may decrease as time passes. For example, the display 120 opaquely displays the first scan data 310 obtained initially, and sets each of the second scan data 320 to the Nth scan data obtained thereafter to a preset initial transparency value. may be displayed as an image in a manner overlapping the first scan data 310 while gradually decreasing the transparency at a preset ratio.

In an embodiment, the display 120 may display a plurality of scan data according to a preset pattern with mutually different combinations of brightness, color, and transparency, for example, the first combination and the second combination as a preset cycle. It can be expressed by emphasizing the overlapping area in a blinking form by repeatedly applying it. In addition to the above-described embodiments, various methods for visually distinguishing overlapping regions between a plurality of scan data may be used.

The display 120 according to an embodiment may distinguish and display an area where a plurality of scan data overlap each other and an area that does not overlap each other. For example, the display 120 may display different regions to be visually distinguished by setting values for brightness, color, or transparency of regions overlapping each other and regions not overlapping each other. For another example, the display 120 displays one of brightness, color, and transparency to be different over time in the case of mutually overlapping regions, and in the case of non-overlapping regions, one of brightness, color, and transparency. The other may be displayed so as to be different according to the passage of time.

In an embodiment, the display 120 may determine a boundary line based on at least one of an area where a plurality of scan data overlap each other and an area that does not overlap each other, and display the boundary line by visually emphasizing the boundary line. For example, the display 120 transparently overwrites an overlapping area of the second scan data 320 on the first scan data 310 with a first transparency value and a first color, and the second scan data 320 ) may be detected and displayed with a preset line thickness and an opaque second color by detecting the boundary lines of the overlapping regions.

In an embodiment, the display 120 displays an image by overlapping a plurality of scan data to be distinguished from each other while one scan data is acquired, and updates the image by integrating the scan data so as not to be distinguished from each other after acquisition of the scan data is completed can do. For example, while the scan data for one scene is being acquired, the display 120 overlaps and displays the scan data to be distinguished from each other as time passes, as shown in FIGS. 4 to 5 , and the acquisition of the scan data Upon completion, as shown in FIG. 6 , the scan data may be integrated and displayed so that the scan data are not distinguished from each other.

In an embodiment, the display 120 may differently display the degree to which a plurality of scan data are distinguished from each other based on a scan progress degree indicating a degree of acquisition of scan data for one scene. For example, after the first scan data 310 for the dental structure 210 rotated at the first angle is acquired, the first scan data 310 is rotated at a second angle according to a scan request by the processor 130 or a user input. When the acquisition of the second scan data 320 for the dental structure 210 starts, the display 120 may update the scan progress for the scene in real time and display it together with the image (refer to identification numbers 410 to 510) ), the display 120 displays at least one of transparency, brightness, and color corresponding to the second scan data 320 based on the scan progress updated in real time as time passes, as shown in FIGS. 4 to 5 . can be changed

In an embodiment, the display 120 updates at least one of transparency, brightness, and color corresponding to the currently acquired scan data from the first set value to the second set value when the scan progress is greater than or equal to the preset first value. and, if the scan progress is equal to or greater than the second preset value, the second set value may be updated back to the first set value. For example, the display 120 overwrites the second scan data 320 with 70% transparency and yellow color on the first scan data 310 when the scan progress with respect to the second scan data 320 is less than 30%. , when the scan progress is 30% or more and 70% or less, the second scan data 320 is overwritten with 30% transparency and red color on the first scan data 310, and when the scan progress is 70% or more, the first scan data ( The second scan data 320 may be overlaid on the 310 with 70% transparency and yellow.

In another embodiment, the display 120 may update at least one of transparency, brightness, and color corresponding to the currently acquired scan data from the first set value to the second set value so as to be inversely proportional to the scan progress. For example, the display 120 may determine the transparency corresponding to the currently acquired scan data based on Equation 1 below.

[Equation 1]

(Here, t represents the transparency corresponding to the currently acquired scan data, t1 and t2 represent the first set value and the second set value, respectively, and s represents the scan progress (%) and is greater than or equal to 1 and less than or equal to 99. can be expressed as a natural number of

In an embodiment, when the acquisition of scan data for one scene is completed, the display 120 sets initial settings for at least one of brightness, color, and transparency corresponding to each of the plurality of scan data (eg, all opaque). can be applied to update the image.

In an embodiment, the display 120 may adjust at least one of transparency, brightness, and color corresponding to the scan data based on the degree to which the plurality of scan data overlap each other. For example, if the area of the mutually overlapping region of the first scan data 310 and the second scan data 320 is greater than or equal to a preset value, the display 120 determines that the mutual overlapping degree is large and specifies a color. It can be fixed with a color (eg red).

The processor 130 according to an embodiment may update the displayed image as additional scan data of the object 200 is acquired. For example, after the image is displayed on the display 120 , the processor 130 receives additionally acquired scan data on the image in which the planned scan data is superimposed whenever additional scan data is acquired through the scanner 110 . The image may be updated and visualized on the display 120 in such a way that it is transparently, brightly, or close to a set color with a preset value.

The processor 130 according to an embodiment may provide information on a region in which an additional scan of the object 200 is recommended based on a degree to which a plurality of scan data overlap each other.

For example, when the acquisition of the second scan data 320 is completed, the processor 130 may include an image area secured above a preset level (eg, resolution, reproducibility, etc.) in the first scan data 310 and the second scan data 310 . Detects an area that does not overlap between the two scan data 320, and determines the recommended rotation axis and rotation angle for securing additional scan data for the detection area based on the most recently moved rotation axis and rotation angle to perform additional scans may be output to the display 120 together with a message recommending . For another example, when the acquisition of the second scan data 320 is completed, the processor 130 may perform an image area secured at a preset level (eg, resolution, reproducibility, etc.) or higher in the first scan data 310 and A region overlapping each other between the second scan data 320 is detected, and an additional scan for the detection region is analyzed as unnecessary, so that the current rotation axis and rotation angle can be excluded from a rotation scenario to be performed later.

Accordingly, the device 100 may provide recommended information on an area requiring image supplementation and a photographing angle therefor, based on an area overlapping between scan data or an area that does not overlap between the scan data and an empty area.

In an embodiment, the processor 130 may move the object 200 based on an area in which an additional scan of the object 200 is recommended and acquire additional scan data. For example, when the scan data is acquired through the scan, the processor 130 determines the recommended rotation axis and rotation angle for securing additional scan data as described above until a separate user input is received, and based on this, the mechanical unit By moving the object 200 through 140 and continuously updating the 3D image in a manner of automatically acquiring the next scan data, the quality of the image, such as resolution and reproducibility, can be improved.

In an embodiment, the processor 130 may overlap the scan data selected by the user based on the history of image update so as to be distinguished from each other. For example, the processor 130 may store and manage a scan data history including changes in brightness, color, and transparency corresponding to a plurality of scan data whenever scan data is acquired, and even after all scans are completed. Any scan data selected by the user based on the scan data history may be displayed in an overlapping manner so as to be mutually distinguished from scan data obtained immediately before it.

Accordingly, the user can visually check the history of which part of the object 200 has been supplemented with the image before and after the desired specific scan time even after all scans are completed.

The processor 130 according to an embodiment may control the overall operation of the device 100 , and may be electrically connected to the scanner 110 , the display 120 , and the mechanical unit 140 to control the flow of data therebetween. have. Also, the processor 130 may include at least some of the functions performed by the display 120 .

In addition, it can be understood by those of ordinary skill in the art that other general-purpose components other than those shown in FIG. 1 may be further included in the device 100 . According to an embodiment, the device 100 includes a user interface for receiving a user input, a communication module for communication with another terminal or server, and hardware and software components (eg, non-contact optical method) for 3D scanning. Alternatively, a laser-based three-dimensional scanning algorithm), etc. may be further included, and according to another embodiment, some of the components shown in FIG. 1 may be omitted.
