[0029] The embodiments of the present application provide a data processing method, apparatus, computer equipment, and storage medium.
[0030] The executor of the data processing method may be the data processing device provided in the embodiment of the present application, or a computer device integrating the data processing device, wherein the data processing device may be implemented in hardware or software, the computer device may be a terminal or a server, and the terminal may be a smart phone, tablet computer, PDA, laptop computer or scanning device, etc.
[0031] It should be noted that the data processing method provided in the present application is applied to the scanning scenario of the target scanning object, and the target scanning object is installed with a target or a first marking point installed in the mouth, and the inside of the mouth of the target includes a first marking point, wherein there are multiple first marking points, and the first marking point installed in the mouth is installed by direct sticking, for example, sticking the marking point on the outer surface of the tooth.
[0032] In other embodiments, the target also includes an outer part of the mouth, the outer part of the mouth includes a second marking point, and the inner part of the mouth and the outer part of the mouth are fixedly connected by a detachable connecting piece, wherein there are multiple second marking points.
[0033] like Figure 1 As shown, in some embodiments, the target can be a jaw fork, which includes an inner part of the mouth 10, an outer part of the mouth 20, and a connector 30 connecting the inner part of the mouth 10 and the outer part of the mouth 20, wherein the inner part of the mouth 10 can be specifically an arc-shaped structure, which fits the gums and is installed on the jaw of the target scan object, for example, it is installed on the gums, teeth, or the place to be repaired or implanted. The outer part of the mouth 20 can be specifically a rectangular structure (in actual application, it can also be set to other shapes as needed, such as a cross structure), which is located outside the mouth of the scan object through a connector 3, which is a detachable connector or an integrated connector, wherein the upper jaw and the lower jaw of this embodiment are both equipped with jaw forks.
[0034] The target scanning object can be an edentulous patient or a edentulous patient.
[0035] Figure 2 This is a flow chart of the data processing method provided in the embodiment of the present application. Figure 2 As shown, the method includes the following steps S110-S130.
[0036] S110 , obtaining oral scan data of a target scan object, where the oral scan data includes intraoral scan data and first marker point scan data of a first marker point.
[0037] like Figure 3 As shown, the oral scan data in this embodiment includes intraoral scan data and first marker point scan data (red dot part) of the first marker point.
[0038] In some embodiments, two methods for acquiring oral scan data are provided. Specifically, before step S110, a first prompt is issued, prompting the user to select a method for acquiring oral scan data. The methods for acquiring oral scan data include scanning and calling. If the user selects the scanning method based on the first prompt, the scanner scans the mouth of the target subject to acquire oral scan data. If the user selects the calling method based on the first prompt, the oral scan data is called from a local database or a cloud server based on the user's call operation.
[0039] It can be seen that the oral scan data in this embodiment can be obtained directly through an intraoral scanner, and can also be obtained through external calls. For example, the oral scan data is the oral scan data obtained by the user through an intraoral scan of the target scan object, and the scan data is stored in a local database or cloud server.
[0040] In some embodiments, during oral scanning, the scanning data of all first marker points during oral scanning (i.e., first marker point scanning data) can be determined by scanning the scanning data of some first marker points. At this time, the oral scanning data of the target scanning object is obtained by the following steps: by performing an oral scan on the target scanning object, first marker point scanning sub-data and intra-oral scanning data are obtained, and the first marker point scanning sub-data includes marker point scanning data of some first marker points; according to the preset first marker point model and the first marker point scanning sub-data, the first marker point scanning data in the oral scanning data is determined, and the first marker point model includes marker point models of each first marker point having a relative position relationship.
[0041] In other embodiments, the first marker point model can be a marker point model including first marker points having a relative positional relationship, or a marker point model including a first marker point and a second marker point outside the target mouth, where each marker point has a relative positional relationship, or a complete target model including the first marker point, the second marker point and geometric features.
[0042] The first marker point model may be preset model data in a standard database. By matching some of the first marker points with the first marker point model, unscanned data may be determined.
[0043] In some embodiments, when the user selects the scanning mode based on the first prompt information, in addition to scanning the inside of the mouth of the target scanning object by the scanner to obtain the mouth scan data, the inside of the mouth of the normal scanning object is also scanned by the scanner to obtain the normal mouth scan data, wherein the normal mouth scan data is the target scanning object without the target and the first landmark point. When the user selects the calling mode based on the first prompt information, the mouth scan data and the normal mouth scan data are called from the local database or the cloud server based on the calling operation of the user. (If the normal mouth scan data is not needed, the scanning or calling of the normal mouth scan data is not needed)
[0044] It can be seen that, in addition to obtaining the mouth scan data of the target scanning object with the target or the first landmark point, the normal mouth scan data without the target and the first landmark is also obtained. If the normal mouth scan data is obtained, the following operations are performed in the step of determining the target data: aligning the mouth scan data and the normal mouth scan data to obtain the target mouth scan data; and aligning the target mouth scan data and the surface scan data according to the first landmark point scan data to obtain the target data. At this time, the user can select to display the target data with or without the landmark point in the mouth.
[0045] In S120, surface scan data of the target scanning object is obtained, and the surface scan data includes first landmark point scan data.
[0046] As shown in Figure 4 In the embodiment, the surface scan data at least includes the first landmark point scan data.
[0047] In addition, in some embodiments, the outside of the mouth of the target includes a second landmark point, and the inside of the mouth and the outside of the mouth are fixedly connected by a detachable connecting piece or an integral connecting piece, as shown in Figure 5 In addition, in some embodiments, the outside of the mouth of the target includes a second landmark point, and the inside of the mouth and the outside of the mouth are fixedly connected by a detachable connecting piece or an integral connecting piece, as shown in
[0048] In some embodiments, the target landmark point model can be a landmark point model including the first landmark point and the second landmark point outside the mouth of the target, and each landmark point has a relative position relationship, and can also be a complete target model including the first landmark point, the second landmark point and the geometric feature. By matching the second landmark point and the target landmark point model, the data that is not scanned can be determined.
[0049] In the embodiment, after the second landmark point scanning data is acquired in the face scanning, the first landmark point scanning data in the face scanning data can be derived through the preset target landmark point model. At this time, in the face scanning, the mouth of the scanning object does not need to be opened (i.e., the first landmark point does not need to be scanned), and the alignment of the intraoral and extraoral data can also be achieved through the first landmark point scanning data.
[0050] In some embodiments, two face scanning data acquisition modes are provided. Specifically, before step S120, second prompt information is sent, the second prompt information is used to prompt the user to select a face scanning data acquisition mode, and the face scanning data acquisition mode includes a scanning mode and a calling mode. At this time, when the user selects the scanning mode based on the second prompt information, the face of the target scanning object is scanned by the scanner to acquire the face scanning data; and when the user selects the calling mode based on the second prompt information, the face scanning data is called from the local database or the cloud server based on the calling operation of the user.
[0051] It can be seen that the face scanning data in the embodiment can be directly obtained through the intraoral scanner, and can also be obtained through external calling. For example, the face scanning data is face scanning data obtained by the user when the target scanning object is scanned before, and the face scanning data is stored in the local database or the cloud server.
[0052] In some embodiments, the face scanning data in the embodiment includes a plurality of frames of scanning data acquired in the up-down movement of the dental arch of the target scanning object. At this time, the target data reflecting the movement of the dental arch of the target scanning object can be determined through the data acquired in steps S110 and S120.
[0053] In another embodiment, the face scanning data in the embodiment can also be data acquired when the oral cavity of the target scanning object is in a static or dynamic state. At this time, the face scanning data in the step at least includes extraoral scanning data, or includes extraoral scanning data and second landmark point scanning data. The comprehensive model of the target scanning object can be determined through the data acquired in steps S110 and S120, and the comprehensive model can reflect a comprehensive three-dimensional visual dental arch model of the target scanning object.
[0054] Specifically, the comprehensive model is a comprehensive model of the dental arch model and the face model of the target scanning object, or a comprehensive model of the dental arch model and the target model. The comprehensive model in the embodiment, in combination with the dental arch movement trajectory, can generate a dynamic model indicating the movement of the dental arch.
[0055] In some embodiments, the partial first landmark points can be scanned, and then the scanning data of the entire first landmark points (i.e., first landmark point scanning data) can be determined through the partial first landmark points. At this time, the surface scanning data of the target scanning object can be obtained through the following steps: the first landmark point scanning sub-data is obtained by performing surface scanning on the target scanning object, and the first landmark point scanning sub-data includes the landmark point scanning data of the partial first landmark points; the first landmark point scanning data in the surface scanning data is determined according to the preset first landmark point model and the first landmark point scanning sub-data, and the first landmark point model includes the landmark point models of the first landmark points having the relative positional relationship. Through matching the partial first landmark points and the first landmark point model, the entire first landmark point data can be determined.
[0056] In other embodiments, the first landmark point model can be a landmark point model including the first landmark points having the relative positional relationship, a landmark point model including the first landmark points and the second landmark points outside the target mouth, the landmark points having the relative positional relationship, or a complete target model including the first landmark points, the second landmark points, and geometric features. The first landmark point model can be preset model data in a standard database. Through matching the partial first landmark points and the first landmark point model, the data that is not scanned can be determined.
[0057] S130, aligning the mouth scanning data and the surface scanning data according to the first landmark point scanning data to obtain target data.
[0058] In this embodiment, the mouth scanning data and the surface scanning data obtained by scanning both include the first landmark point scanning data (common landmark points). At this time, the mouth scanning data and the surface scanning data can be aligned in a unified coordinate system based on the first landmark point scanning data to obtain the required target data.
[0059] In some embodiments, referring to Figure 6 , the surface scanning data includes multiple frames of scanning data obtained in the up-down movement process of the dental arch of the target scanning object; the target data is obtained by aligning the mouth scanning data and the surface scanning data according to the first landmark point scanning data, including:
[0060] S1301, aligning the mouth scanning data and the surface scanning data according to the first landmark point scanning data;
[0061] S1302, obtaining the dental arch model of the target scanning object according to the intraoral scanning data;
[0062] S1303, obtaining the dental arch movement trajectory of the target scanning object according to the surface scanning data;
[0063] S1304, generating the target data according to the dental arch model and the dental arch movement trajectory.
[0064] Specifically, the embodiment registers and aligns the mouth scanning data and the face scanning data according to the first landmark points, realizes accurate splicing of the mouth scanning data and the face scanning data, obtains post-splicing data, acquires a dental model of the target scanning object based on intraoral scanning data in the post-splicing data, determines a dental motion trajectory according to the extraoral scanning data and the time sequence of each frame of the extraoral scanning data, and finally applies the dental motion trajectory to the dental model to obtain target data. At this time, the target data is a model indicating dental motion.
[0065] In some embodiments, the dental motion trajectory can be determined according to the first landmark point scanning data in the face scanning data, that is, the motion trajectory of the first landmark point is determined as the dental motion trajectory. In other embodiments, the extraoral part of the target includes a second landmark point, the intraoral part is fixedly connected to the extraoral part through a detachable connecting piece or an integral connecting piece, and the face scanning data further includes second landmark point scanning data of the second landmark point; the method for acquiring the dental motion trajectory of the target scanning object according to the face scanning data comprises: determining the dental motion trajectory according to the second landmark point scanning data in the face scanning data, that is, determining the motion trajectory of the second landmark point as the dental motion trajectory, or determining the dental motion trajectory according to the first landmark point scanning data and the second landmark point scanning data in the face scanning data, that is, determining the motion trajectories of the first landmark point and the second landmark point as the dental motion trajectory.
[0066] When the dental motion trajectory is determined according to the second landmark point scanning data in the face scanning data, after the alignment of the mouth scanning data and the face scanning data is completed, subsequent target tracking can be performed only through the second landmark point or through the first landmark point and the second landmark point. The second landmark point is located outside the mouth and is easier to track, and the situation that tracking fails due to the first landmark point being blocked by the lips can be avoided.
[0067] Through the embodiment, the dental motion trajectory of a patient with or without teeth can be acquired. In addition, through the embodiment, a dental motion model (target data indicating dental motion) is acquired without acquiring the external features of the scanning object. When face scanning is performed, only the first landmark point can be scanned, only the second landmark point can be scanned, or the first landmark point and the second landmark point can be scanned. The dental motion model can be directly acquired through target tracking, the calculation amount for acquiring the dental motion model can be reduced, and the trajectory accuracy of the dental motion model can be improved.
[0068] In other embodiments, the face scanning data further includes extraoral scanning data, and the target data is a comprehensive model; the method for aligning the mouth scanning data and the face scanning data according to the first landmark point scanning data to obtain the target data comprises:
[0069] The intraoral scanning data and the extraoral scanning data are aligned in a unified coordinate system according to the first landmark point scanning data to splice the intraoral three-dimensional scanning data and the extraoral scanning data, and obtain a comprehensive model.
[0070] In summary, the data processing method provided in this embodiment is applied to a scanning scenario of a target scanning object, wherein the target scanning object is installed with a target or a first marker point installed in the mouth, and the interior of the mouth of the target includes the first marker point. The method includes: obtaining oral scan data of the target scanning object, the oral scan data including oral scan data and first marker point scan data of the first marker point; obtaining face scan data of the target scanning object, the face scan data including first marker point scan data; and aligning the oral scan data and face scan data according to the first marker point scan data to obtain target data. The embodiment of the present application aligns the common marker points (first marker point scan data) in the oral scan data and the face scan data, thereby reducing cumulative errors and improving the splicing accuracy between the oral scan data and the face scan data.
