[0016] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure more clear, the following clearly and comprehensively describes the technical solutions in the embodiments of the present disclosure, and it should be understood that the described embodiments are only some of the embodiments of the present disclosure, and not all of the embodiments, and a person skilled in the art can easily understand that all other embodiments obtained based on the embodiments of the present disclosure without any creative work are all included in the claims of the present disclosure.

[0017] FIG. 1 is a block diagram of a scanning device provided by an embodiment of the present disclosure. As shown in FIG. 1, the scanning device includes: The scanning body 11 includes an auxiliary feature 12 connected to the scanning body 11, and auxiliary feature points 13 are provided on the scanning body 11 and / or the auxiliary feature 12.

[0018] In the embodiment of the present disclosure, auxiliary features 12 connected to the scanning body 11 are installed, so that the connection of multiple scanning devices can be realized by connecting the auxiliary features 12 to each other, thereby improving the accuracy of intraoral scanning; auxiliary feature points 13 are installed on the scanning body 11 and / or the auxiliary feature 12, so that positioning can be performed based on the coordinate information of the auxiliary feature points 13, thereby improving the accuracy of intraoral scanning implants and further improving the utilization rate of the scanning devices.

[0019] In the embodiment of the present disclosure, the scanning body 11 is rod Or it may be a denture or the like.

[0020] In some embodiments, the scanning body 11 is provided with an angle-adjustable connection structure that connects to the auxiliary features 12 .

[0021] Here, the angle of the angle-adjustable connecting structure can be selected and set based on the application scenario, for example, the scanning body 11 is fixedly connected to the auxiliary feature 12 perpendicularly or at a predetermined angle.

[0022] It should be noted that the scanning body 11 may be connected to the auxiliary features 12 on one or both sides, which is a matter of selection based on the specific application scenario.

[0023] Illustratively, as shown in FIG. 2, the scanning body 11 is orthogonally connected to the auxiliary feature 12, which is a rectangular parallelepiped.

[0024] In some embodiments, the auxiliary feature 12 is connected to the scanning body 11 via a threaded connection, and / or the auxiliary feature 12 is connected to the scanning body 11 via a plug, and / or the auxiliary feature 12 is fixedly connected to the scanning body 11 with a sleeve, and / or the auxiliary feature 12 is connected to the scanning body 11 by abutment or magnetic attraction.

[0025] Illustratively, as shown in FIG. 3a, the auxiliary feature 12 is connected to the scanning body 11 via a plug, and as shown in FIG. 3b, the auxiliary feature 12 is fixedly connected to the scanning body 11 with a sleeve.

[0026] In some embodiments, the auxiliary feature 13 may be a spherical shape, and / or a code, and / or a mark, and / or a color, where the auxiliary feature 13 may be the shape of the auxiliary feature itself.

[0027] Here, each auxiliary feature point 13 can uniquely identify one feature, that is, auxiliary feature points 13 are installed on the scanning body 11 and / or auxiliary feature 12, and each auxiliary feature point 13 can uniquely identify the position feature corresponding to the scanning body 11 and / or auxiliary feature 12. For example, target feature a and target feature b are installed at position 1 on the scanning body 11 and position 2 on the auxiliary feature 12, respectively, and target feature a can uniquely identify the position feature at position 1 on the scanning body 11, and target feature b can uniquely identify the position feature at position 2 on the auxiliary feature 12.

[0028] It should be understood that any different shape, color, two-dimensional code, etc. on the scanning body 11 and / or auxiliary feature 12 that can uniquely identify the positional feature corresponding to the scanning body 11 and / or auxiliary feature 12 may also be used as the auxiliary feature point 13.

[0029] In the embodiments of the present disclosure, if the auxiliary feature is spherical, it may be understood that the auxiliary feature 12 is set in a spherical shape; if the auxiliary feature is a code, it may be understood that a two-dimensional code or the like is printed on the auxiliary feature 12; if the auxiliary feature is a mark, it may be understood that a shape such as a circle or triangle and a color different from the auxiliary feature 12 is printed on the auxiliary feature 12; and if the auxiliary feature is color, it may be understood that a different color is directly printed on the auxiliary feature 12.

[0030] In some embodiments, the auxiliary features 12 are drum-shaped and / or rectangular and / or conical.

[0031] Illustratively, as shown in FIGS. 4a-4c, different shapes of auxiliary features 12 further meet the intraoral scanning needs of different occasions.

[0032] In an embodiment of the present disclosure, one scanning body 11 may further be connected to two auxiliary features 12, and as shown in FIG. 4d, the scanning body 11 is connected to two rectangular auxiliary features 12.

[0033] In some embodiments, the scanning body 11 is provided with an anti-rotation structure that is connected to the implant body.

[0034] In the embodiment of the present disclosure, the scanning body 11 is connected to the implant body in a non-rotational manner, so that the scanning body 11 can be controlled to rotate around an axis. Therefore, when the auxiliary features 12 contact each other, the scanning body 11 can be controlled to rotate around an axis. By connecting multiple scanning bodies 11 by methods such as abutting or overlapping, the accuracy of intraoral scanning can be improved.

[0035] In some embodiments, the auxiliary features 12 are positioned to extend laterally outward from the scanning rod and are used to continuously distribute the auxiliary feature points 13 on the two auxiliary features 12 by fitting into auxiliary features 12 on adjacent intraoral scanning rods.

[0036] In some embodiments, two auxiliary features are connected to connect two scanning bodies corresponding to the two auxiliary features, and auxiliary features of different lengths or multiple auxiliary features whose lengths can overlap are installed so that the distribution distance between the auxiliary feature points 13 installed on the two auxiliary features is less than a predetermined distance threshold.

[0037] Here, the auxiliary feature points 13 can be selected as one or more of a spherical shape, a code, and a mark based on the needs of the application scenario, and the auxiliary feature points 13 are used to obtain the corresponding position coordinate points during the intraoral scanning process, thereby realizing accurate positioning of the scanning rod.

[0038] In the embodiment of the present disclosure, the coordinate information of the auxiliary feature points 13 can further improve the positioning accuracy of the intraoral scanning, so that images of different viewing angles of the oral cavity can be acquired through the scanning window during the intraoral scanning process. In order to avoid the problem of accuracy reduction due to subsequent data stitching errors, the distribution distance between the auxiliary feature points 13 needs to be controlled to be smaller than a preset distance threshold during installation, so as to ensure that the number of auxiliary feature points 13 in the images acquired through the scanning window is greater than a preset number threshold, thereby ensuring the accuracy of the intraoral scanning. Here, the distance threshold and number threshold can be adjusted in real time based on the accuracy needs of different application scenarios, and the embodiment of the present disclosure is not particularly limited.

[0039] In one example scenario, multiple intraoral scanning rods are attached to a target oral cavity, the intraoral scanning rods include a scanning body connected to an implant body and auxiliary features connected to the scanning rods, the intraoral scanning rods are provided with target features, and the target features are continuously distributed on the scanning rods and / or auxiliary features, and the target features are not distributed on one side of the scanning rods and / or auxiliary features.

[0040] Specifically, the intraoral scanner scans the target oral cavity, acquires multiple frames of images, and transfers them to the data processing module for data processing, which performs the following method.

[0041] Acquire a plurality of frames of images, and acquire initial three-dimensional data of the target oral cavity based on the plurality of frames of images, the initial three-dimensional data including an initial point set of the target oral cavity in the same coordinate system and three-dimensional coordinate measurement values ​​of the target features;

[0042] Obtain a preset model of the intraoral scanning rod, the preset model including the 3D coordinate true value of the target feature and the real point set (the 3D coordinate true value of each point) of the intraoral scanning rod in the same coordinate system; stitching the initial point set of the target oral cavity and the real point set of the intraoral scanning rod according to the correspondence relationship between the three-dimensional coordinate measurement value of the target feature and the true value; The positioning information of the intraoral scanning rod is determined based on the real point set of the stitched intraoral scanning rod, and the positioning information of the intraoral scanning rod is the positioning information of the implant body, and the tooth body can be designed based on the positioning information, and the designed and manufactured tooth body can be fitted to the implant body.

[0043] 5 is a flowchart of a scanning device connection method provided by an embodiment of the present disclosure, which may be performed by a scanning device connection device, where the device may be implemented using software and / or hardware and may generally be integrated into an electronic device. As shown in FIG. 5, the method includes the following steps:

[0044] In step 101, a fixed distance between each scanning body in the oral cavity region is obtained.

[0045] Here, the oral cavity region refers to the region of the teeth in the oral cavity, and the oral cavity region of different users is different. It should be understood that the oral cavity region is analyzed in advance to determine the position of each implant body, and the scanning bodies are connected to the implant bodies, so the number of scanning bodies and the distance between the scanning bodies are fixed, that is, the distance between the scanning bodies is a fixed distance.

[0046] Specifically, a fixed distance between each scanning body is determined based on the distance between the implant bodies.

[0047] In step 102, each scanning body is connected by a target auxiliary feature within the oral cavity region by determining a target length of the target auxiliary feature based on a fixed distance.

[0048] In an embodiment of the present disclosure, the scanning device includes a scanning body and an auxiliary feature, and based on the description of the scanning device, the scanning body and the auxiliary feature may be connected separately, and the shape and length of the auxiliary feature may both be flexibly set, so that a target auxiliary feature of a target length can be selected based on a fixed distance between the scanning bodies, for example, the fixed distance between two scanning bodies is 5 millimeters, and one target auxiliary feature with a target length of 2 millimeters and one target auxiliary feature with a target length of 3 millimeters can be selected to establish a connection between the two scanning bodies.

[0049] As an example of one scenario, a fixed distance between each scanning body is determined in advance based on the distance between the implant bodies, for example, the fixed distance between scanning bodies AB is 5 millimeters, and the fixed distance between scanning bodies CD is 3 millimeters, and target lengths corresponding to each auxiliary feature are stored in advance, for example, target auxiliary feature a1 is 2 millimeters, and target auxiliary feature a2 is 3 millimeters.Therefore, by determining to match target auxiliary features a1 and a2 between scanning bodies AB, target auxiliary features a1 and a2 are connected between scanning bodies AB, and target auxiliary feature a2 is matched between scanning bodies CD, and another target auxiliary feature identified as a2 is connected between scanning bodies CD.

[0050] In the embodiment of the present disclosure, if the total distance between any two target auxiliary features is greater than a fixed distance, the two target auxiliary features are connected according to a preset connection method.

[0051] Specifically, when the total distance between any two target auxiliary features is greater than a fixed distance, in the embodiments of the present disclosure, the scanning body may be designed to be anti-rotational and can rotate, so that any two target auxiliary features can be connected according to a pre-set connection method, such as abutment, thereby ensuring the accuracy of intraoral scanning and further improving the adaptability of implant scanning.

[0052] As an example, as shown in Figure 6a, two scanning bodies are connected via two target auxiliary features to realize the connection of multiple scanning devices, maintaining the relative positional relationship between the scanning devices. After the scanning rod is attached to the oral cavity, a rigid body can be formed, which will not be deformed by deformation of soft tissues such as the gums, thereby improving the accuracy of intraoral scanning. Preferably, the shapes of the multiple scanning devices are different so that the scanner can be easily identified. If the shapes of the multiple scanning devices are the same, the difficulty of the algorithm may increase. As shown in Figure 6b, the oral cavity region is analyzed in advance to determine the position of each implant body 20, and the scanning body 11 is connected to the implant body 20, with the positions of the two corresponding to one another.

[0053] The connection means of the scanning device provided by the embodiment of the present disclosure obtains a fixed distance between each scanning body within the oral cavity region, and determines a target auxiliary feature of a target length based on the fixed distance, thereby connecting each scanning body with the target auxiliary feature within the oral cavity region. Using the above technical solution, the intraoral cavity can be directly scanned through the intraoral scanner to obtain scanning rod data and feature data, thereby improving the scanning accuracy of the scanning rod.

As shown in FIG. 7, the device includes: a distance acquisition module 301 used to acquire a fixed distance between each scanning body in the oral cavity region; and a determination module 302 used to connect each of the scanning bodies with the target auxiliary features within the oral cavity region by determining a target length of the target auxiliary feature based on the fixed distance.

[0055] Optionally, the apparatus comprises: The device further includes an adjustment module that is used to connect any two of the target auxiliary features according to a preset connection method when the total length of the distance between any two of the target auxiliary features is greater than the fixed distance.
