The manipulator may include at least one of a position movement, size conversion, rotation, free movement, free rotation, micro-movement, micro-rotation, length adjustment, and diameter adjustment interface in a preset axial direction for the model object in 3D space. have.

The method for selecting a manipulator may further include selecting a manipulator based on a user's selection action for a selection candidate recommended at a current mouse cursor position.

In the manipulator selection method, after recommending the manipulator, if a predetermined motion other than the user's selection motion is detected with respect to the recommended selection candidate, it is determined that the user does not select the recommended selection candidate, and a new current position of the moving mouse cursor The method may further include searching for a new manipulator that satisfies the selection condition based on , and previewing the searched new manipulator as a selection candidate on the screen.

In the step of setting the search area, an area within a preset range centered on the current position of the mouse cursor may be set as the search area.

The manipulator that meets the preset selection condition is the manipulator closest to the current position of the mouse cursor among the manipulators in the search area. It can be recommended as a first choice candidate.

In the step of recommending the manipulator, when the selection candidate is shown in advance, it can be displayed by dividing it into identifiable visual information.

The manipulator selection method may further include providing the screen by enlarging the screen or changing the view direction for the user to select the manipulator.

A method for selecting a manipulator according to another embodiment includes displaying a manipulator for modifying a model object designed in a dental image on a screen, and selecting a manipulator to be selected by a user on the screen. Detecting a position, setting a search area based on the detected current position of the mouse cursor, searching for a manipulator that meets a preset selection condition within the set search area, and selecting the manipulator selected by the user. and recommending a manipulator by determining whether it is the same as the manipulator and displaying the newly searched manipulator on the screen if not identical.

The manipulator selection method may further include, if the searched manipulator is the same as the manipulator selected by the user, classifying and displaying the manipulator selected by the user as identifiable visual information or activating a manipulator function.

A dental image processing apparatus according to another embodiment includes an output unit for displaying manipulators for modifying a model object designed for a dental image on a screen, and a user according to a user action of moving a mouse to a manipulator that the user wants to select on the screen. An input unit that receives a manipulation signal, and the current position of the moving mouse cursor on the screen is detected based on the user manipulation signal input through the input unit, and a preset selection condition within the search area set based on the detected current position of the mouse cursor and a control unit for recommending a manipulator by searching for a manipulator that matches the , and displaying the searched manipulator as a selection candidate in advance on the screen through an output unit.

The control unit may select the manipulator based on the user's selection operation for the selection candidate recommended at the current mouse cursor position.

The controller may recommend a manipulator closest to the current position of the mouse cursor among manipulators within the search area as the highest selection candidate.

A dental image processing apparatus according to another embodiment includes an output unit for displaying on a screen a manipulator for modifying a model object designed for a dental image, and a user according to a user action of moving a mouse to a manipulator that the user wants to select on the screen. An input unit receiving a manipulation signal, and detecting a current position of the mouse cursor based on a user manipulation signal input through the input unit, setting a search area based on the detected current position of the mouse cursor, and presetting within the set search area and a control unit that searches for a manipulator that meets a set selection condition, determines whether the searched manipulator is the same as the manipulator selected by the user, and recommends the manipulator by displaying the newly searched manipulator on the screen if not identical.

According to a method for selecting a manipulator and a dental image processing apparatus therefor according to an embodiment, when a user needs to select a manipulator for correcting a model object designed for a dental image in a treatment plan establishment process in dental image processing software, the user uses a mouse cursor is moved to the correct position of the manipulator, eliminating the need for selection.

For example, when the user moves the mouse to a manipulator that is determined as a manipulator for manipulation, preset selection conditions within the search area based on the current position of the mouse cursor (e.g., based on the current position of the mouse cursor) The manipulator that matches the nearest manipulator) is automatically searched internally by the software, and then the searched manipulator is displayed in advance on the screen. Accordingly, the user does not need to find the correct manipulator by moving the mouse additionally, check the recommended manipulator on the current screen, select the correct manipulator only by clicking the mouse at the current mouse position, and proceed with the next operation. there will be This method has two advantages:

First, the user can easily select the correct manipulator based on the current position of the mouse cursor regardless of the size of the manipulator displayed on the screen. In this case, the number of tasks such as zoom-in of the screen or setting the camera direction is reduced. In particular, in the process of selecting a manipulator displayed on the screen in the form of a line, usability and convenience can be greatly improved.

Second, the software automatically analyzes and finds the closest manipulator within the search area based on the current position of the mouse cursor, so even if many GUIs are clustered in a narrow area, the user needs to move and position the mouse cursor over the desired GUI precisely. Without it, simply move the mouse to find the approximate location where the desired GUI is selected and activated. In addition, it is possible to obtain the effect of greatly improving usability and convenience in the manipulator setting work process.

However, the embodiments of the present invention illustrated below may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described below. The embodiments of the present invention are provided to more completely explain the present invention to those of ordinary skill in the art to which the present invention pertains.

1 to 3 are diagrams illustrating a model object modification screen using a manipulator according to an embodiment of the present invention.

In more detail, FIG. 1 illustrates a model object rotation screen using a manipulator, FIG. 2 illustrates a model object size conversion screen using a manipulator, and FIG. 3 illustrates an example of a manipulator.

1 to 3 , the dental image processing software displays the model object 1 and the manipulator together on the screen. The model object 1 is model data that is virtually designed on a dental image, and may be, for example, a tooth model, a fixture model, or a prosthesis model. The prosthesis model includes a crown, an inlay, an onlay, a coping, and a pontic. 1 to 3 show a tooth model.

The manipulator is a virtual graphical user interface (GUI, hereinafter referred to as 'GUI') displayed on the screen to facilitate user manipulation for modifying the model object 1, and is located around the model object 1 is displayed At this time, 'correction' is a concept that includes all corrections of the position, size, orientation, rotation, length, diameter, etc., of the model object (1). used For example, the manipulator includes a rotation manipulator 10 , a position movement manipulator 12 , a size change manipulator 14 , a length control manipulator, a diameter control manipulator, and the like.

The manipulator may be a GUI for modifying the model object 1 in the ± direction of a preset axis (eg, X, Y, Z axis), respectively, as shown in FIGS. 1 and 2 . However, it is possible not only to have a fixed axis, but also to freely modify it without a fixed axis limitation. For example, free rotation and free movement are possible, and it is also possible to precisely modify such as fine movement and fine rotation. The micro-movement manipulator is a user interface displayed on the screen for micro-moving a fixture vertically or horizontally in parallel. The micro-rotation manipulator is a user interface displayed on the screen for micro-rotation of the model object 1 . The length adjustment manipulator is a user interface for adjusting the length of the model object 1 . The diameter adjustment manipulator is a user interface for adjusting the diameter of the model object 1 . The free movement manipulator is a user interface for freely moving the model object 1 . The free rotation manipulator is a user interface for freely rotating the model object 1 .

Furthermore, the manipulator further includes an interface for guiding rotation with a circle or sphere-shaped outline when rotating as shown in FIG. 1, and an interface for guiding the size transformation with a hexahedral outline when changing the size as shown in FIG. 2, etc. may include 1 and 2 illustrate a method of position movement, size conversion, and rotation in six directions (± X, ± Y, ± Z) in a three-dimensional space.

The manipulator may be expressed in any form to facilitate user's modification, and may be displayed on the screen in the form of an arrow, a cylinder, a straight line, a handle, a circle, and the like. For example, as shown in FIG. 3 , the rotation manipulator 10 may be represented by a rotation handle 100 and a rotation arrow 102 , and the position movement manipulator 12 is positioned It may be expressed as a translation arrow, and the scaling manipulator 14 may be expressed as a scaling handle.

Since there are various manipulators for modifying the model object 1 as described above, a method in which a user can easily select a desired manipulator is proposed.

A general method for selecting a manipulator is to output the model object and manipulators to the screen, select (for example, click) the manipulator desired by the user using the mouse, and then use the selected manipulator to modify the model object. will do The general method described above can be organized into sequential continuous operations as follows.

1. The model object to be modified using the manipulator and the corresponding manipulator are displayed on the screen.

2. Visually check the manipulator corresponding to the model object to be modified by the user. In this case, the user can adjust the camera view direction or the size of the model in the screen as needed.

3. The user moves the mouse cursor over the manipulator.

4. After positioning the mouse cursor accurately on the manipulator, click the mouse at the moved position to select the manipulator and check the selection result displayed on the screen.

5. If the manipulator desired by the user is not selected correctly, repeat from step 2.

6. If the desired manipulator is selected correctly, use the mouse drag action to modify the model object.

As shown in FIGS. 1 to 3 , it can be a very difficult and inconvenient task for the user to accurately click the manipulator with the mouse. For example, if the GUI representing the manipulator is expressed very small or very thin on the screen, it is difficult to perform an accurate selection operation, and additionally, it is necessary to perform additional operations such as magnifying the screen and changing the camera view direction. It is not easy to accurately select a manipulator expressed as

In order to solve the above problem, the present invention provides a method for quickly and easily selecting a manipulator without the process of moving the mouse to an exact position in pixels, magnifying the screen, changing the camera view direction, etc. in the process of selecting the GUI representing the manipulator. suggest

Referring to FIG. 4 , the dental image processing apparatus 4 is software for processing a dental image. For example, the software includes prosthesis design software, guide software, scanning software, and the like. In addition, it can be applied to other general medical software other than for dental surgery. Dental surgery may include prosthetic surgery, implant surgery, and the like. The prosthesis design software performs the CAD process to help prosthetic teeth in actual dentistry. The prosthetic CAD process refers to a series of processes in which a patient's dental data is acquired, a virtual prosthesis model is retrieved from a library through control by a computer program, and then is virtually placed at a target position of the dental model. The tooth model is data having two-dimensional and three-dimensional information on teeth including damaged target teeth.

The dental image processing device 4 is an electronic device capable of executing dental image software, and includes a computer, a notebook computer, a laptop computer, a tablet PC, a smartphone, a mobile phone, a PMP (Personal Media Player), and a PDA (Personal Digital Assistants). etc.

Referring to FIG. 4 , the dental image processing apparatus 4 according to an embodiment includes a data acquisition unit 40 , a storage unit 42 , a control unit 44 , an input unit 46 , and an output unit 48 . .

The data acquisition unit 40 acquires image data from a patient. Image data necessary for establishing a treatment plan using dental images include CT data and oral model data. The data acquisition unit 40 may execute the CT data and the oral model data in software or load data stored in a web page and a server.

The oral model data is data having information on actual teeth including damaged teeth. Oral model data is dental model scan data obtained by scanning a plaster model created by imitating a patient's mouth with a 3D scanner, or an impression created by imitating a patient's oral cavity by scanning a 3D scanner. It may be impression body scan data acquired, or oral scan data acquired by scanning the inside of the patient's oral cavity using a 3D intra-oral scanner. The acquired oral model data may be stored in the storage 42 .

The storage unit 42 stores various data such as information necessary for performing the operation of the dental image processing apparatus 4 and information generated according to the operation. The storage unit 42 according to an embodiment stores the oral model data and CT data of an individual patient, and the user requests the oral model data and CT data of a specific patient from among the entire oral model data and CT data during dental treatment simulation. may be provided to the control unit 44 according to the At this time, the storage unit 42 stores the image of the upper and lower teeth of an individual patient, and sends the image of the upper and lower teeth matched to the oral model data and CT data of a specific patient to the user's request. Accordingly, it may be provided to the control unit 44 . In addition, the storage unit 42 may have a tooth model library composed of a plurality of tooth models, and provide it to the control unit 44 .

The control unit 44 controls each component while establishing a surgical plan through control by computer software. The control unit 44 manages screen information displayed on the screen through the output unit 48, and performs a simulation of designing and placing a virtual model object to be implanted in a dental image. A dental image in which a virtual model object is implanted means a two-dimensional, three-dimensional, or the like, multidimensional image in which a patient's tooth arrangement is generated for establishing a dental surgery plan. Various types of images such as X-ray, CT, panoramic image, scan image, image generated through reconstruction, and image obtained by matching multiple images can be used for dental surgery planning.

The controller 44 according to an embodiment sets a manipulator for modifying the model object. The control unit 44 proposes a method for enabling a user to select a manipulator easily and accurately. For example, the control unit 44 detects the current position of the moving mouse cursor on the screen based on a user motion of moving the mouse to the manipulator that the user wants to select on the screen, and a search area based on the detected current mouse cursor position. The manipulator is recommended by searching for a manipulator that satisfies the preset selection condition in the . At this time, if the manipulator recommended by the software matches the manipulator that the user wants to select, the user can move the mouse further through the selection action of clicking the mouse at the current mouse cursor position without the trouble of moving the mouse to the correct position. It is possible to select the correct manipulator without By using this method, the user can create and edit manipulators easier, faster, and more efficiently than using the existing method.

The input unit 46 receives a user manipulation signal. For example, a user manipulation signal for selecting a manipulator may be input on the screen. In addition, a user manipulation signal for moving the position of the mouse cursor on the screen may be input. The user manipulation signal may be input by a user action through a pointing device, and the pointing device includes all input devices such as a mouse, a keyboard pen, and a touch screen. Examples of the user operation include an operation in which a user moves a mouse cursor on a screen using a mouse, an operation in which a user selects a predetermined manipulator on the screen through a pen or a touch on a touch screen type screen, and the like.

5 is a diagram illustrating a flow of a method for selecting a manipulator according to an embodiment of the present invention.

Referring to FIG. 5 , the software displays a manipulator for modifying a model object designed for a dental image on the screen ( S51 ). Then, the software detects the current position of the mouse cursor moving on the screen based on the user's motion of moving the mouse to the manipulator that the user wants to select on the screen (S52).

Then, the software sets a search area based on the detected current position of the mouse cursor (S53). The search area is an area formed within a preset distance from the current position of the mouse cursor as a center point. For example, a circle or a sphere having a certain radius based on the current position of the mouse cursor may be defined as the search area.

Then, the software searches for a manipulator that meets the preset selection condition within the set search area (S54). The preset selection condition may be a manipulator closest to the current position of the mouse cursor within the search area.

Then, the software recommends the manipulator in such a way that the searched manipulator is shown in advance as a selection candidate on the screen (S55). In the step of detecting the current position of the mouse cursor (S52), the user visually checks the part determined to be the manipulator to be set, and then moves the mouse cursor to the confirmed manipulator part. Before moving, the software outputs a manipulator that meets the preset selection condition in the search area in the manipulator recommendation step S55 as a selection candidate in a preview format on the screen. At this time, if the selection candidate shown on the screen is a manipulator that the user wants to select, there is no need to move the mouse to the corresponding manipulator anymore, and the user performs a selection action (for example, clicking the mouse) at the current mouse cursor position. Select the manipulator through the screen, and check the selection result displayed on the screen. On the other hand, when the selection candidates shown on the screen are not satisfactory, the user continues to move to a desired manipulator part or performs a predetermined operation such as right-clicking so that the recommended manipulator disappears. In this case, the software searches for a new manipulator that meets the selection condition on the basis of the new current position of the mouse cursor being moved by the user's mouse movement, and repeats the process of showing the searched new manipulator as a selection candidate in advance on the screen. .

In the step of recommending the manipulator ( S55 ), when the software outputs the selection candidates in a preview format, the selection candidates may be classified and displayed as identifiable visual information. To this end, when a manipulator that meets a preset selection condition in the search area searches, a function or UI that outputs the search result in a preview format on the screen so that the user can check it should be provided. In this case, as a method of classifying selection candidates into identifiable visual information and displaying the selection candidates, there is a method of changing and displaying at least one of a color, shape, size, area, thickness, and emphasis of the selection candidate.

6 is a diagram illustrating a flow of a method for selecting a manipulator according to another embodiment of the present invention.

In the manipulator selection method described above with reference to FIG. 5 , the software searches for a candidate manipulator while the user moves the mouse to the manipulator to be set on the screen, and the candidate manipulator is searched in a preview method before the user moves to the corresponding manipulator. way to display. In contrast, in the manipulator selection method described with reference to FIG. 6 , when an error occurs when the user selects a manipulator to be set on the screen (for example, when the selected manipulator is not the manipulator intended by the user, the selected manipulator is not the optimal manipulator, etc.), the error is corrected and the optimal manipulator is marked as a candidate manipulator.

More specifically, referring to FIG. 6 , the software displays a manipulator for modifying a model object designed for a dental image on the screen ( S61 ).

Then, the software detects the current position of the mouse cursor based on a user action of selecting a manipulator that the user wants to select on the screen (S62). In this case, the user action corresponds to an action of selecting a manipulator determined as a manipulator to be selected by the user on the screen by clicking a mouse or the like.

Then, the software sets a search area based on the detected current position of the mouse cursor (S63), and searches for a manipulator that meets the preset selection condition within the set search area (S64). Then, the software determines whether the searched manipulator is the same as the manipulator selected by the user (S65). At this time, if they are not the same (S66), the manipulator is recommended in such a way that the newly searched manipulator is displayed on the screen (S67). On the other hand, if the searched manipulator is the same as the manipulator selected by the user (S66), the manipulator selected by the user can be classified and displayed as identifiable visual information or the manipulator function can be activated immediately (S68).

7 is a diagram illustrating a screen for setting a search area and selecting a manipulator within the set search area according to an embodiment of the present invention.

Referring to FIG. 7 , when the software enters the model object modification screen using the manipulator, a manipulator for modifying the model object 7 is displayed around the model object 7 . At this time, the software detects the current position of the mouse cursor 70 moving on the screen based on the user's motion of moving the mouse to the manipulator that the user wants to select. Then, the search area 72 is set based on the detected current position of the mouse cursor 70 . The search area 72 for manipulator selection can be defined in various methods and forms as needed. For example, an area within a preset range based on the current position of the mouse cursor 70 may be set as the search area 72 . In FIG. 7 , a circle or a sphere having a predetermined radius based on the current position of the mouse cursor 70 is defined as the search area 72 . However, the shape of the search area 72 may be various, such as a sphere, a circle, a rectangle, and a rhombus.

The software searches for a manipulator meeting a preset selection condition within the set search area 72 and recommends the manipulator in a manner that previews the searched manipulator as a selection candidate on the screen. The selection condition setting is a part that defines the characteristic of the most suitable manipulator among the manipulators included in the search area 72 and a formula for searching for it. For example, the software recommends a given manipulator 74 within the search area 72 as a selection candidate as shown in FIG. In FIG. 7 , one manipulator 74 is located in the search area 72 . However, if a plurality of manipulators are formed in the search area 72 , the manipulator closest to the current position of the mouse cursor 70 is selected from among the plurality of manipulators. can be nominated as candidates.

The software can select as the final manipulator without further mouse movement based on the user's selection motion for the recommended selection candidate at the current position of the mouse cursor 70, and activates the manipulator function upon selection. Here, depending on the setting, the user may select by moving the mouse cursor to the final manipulator.

When the software outputs the selection candidates in the preview format, they can be displayed separately as identifiable visual information. For example, an appropriate method may be applied, such as changing the color of the selection candidate differently and showing it or increasing the size to show it. 7 illustrates a method for highlighting by changing the color of the manipulator 74, which is a selection candidate recommended by software, as an example.

Referring to FIG. 7 , if the user visually confirms the part determined to be the manipulator and then moves the mouse cursor 70 to the confirmed manipulator part, the software will display the mouse cursor before moving the mouse cursor to the visually confirmed part of the manipulator. Based on the current position of 70 , the manipulator 74 satisfying the preset selection condition in the search area 72 is output as a selection candidate in a preview format on the screen to recommend the manipulator.

In this case, if the selection candidate shown on the screen is the manipulator desired by the user, there is no longer a need to move the mouse to the corresponding manipulator, and the user can select Select a selection candidate and check the selection result displayed on the screen. The software can select the manipulator without further mouse movement based on the user's selection action for the recommended selection candidate at the current mouse cursor 70 position, and activate the selected manipulator function.

So far, the present invention has been focused on the embodiments thereof. Those of ordinary skill in the art to which the present invention pertains will understand that the present invention can be implemented in modified forms without departing from the essential characteristics of the present invention. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense.
