[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 is to be understood that the described embodiments are only some embodiments of the present disclosure, and not all embodiments, and any other embodiments obtained by a person skilled in the art based on the embodiments of the present disclosure without creative labor are all within the scope of 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 apparatus includes a scanning body 11 and 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 an embodiment of the present disclosure, an auxiliary feature 12 is provided to be connected to the scanning body 11, so that the auxiliary features 12 can be connected to each other to realize the connection of multiple scanning devices, thereby improving the accuracy of intraoral scanning; auxiliary feature points 13 are provided on the scanning body 11 and / or the auxiliary feature 12, so that the accuracy of the intraoral scanning implant can be improved by positioning based on the coordinate information of the auxiliary feature points 13, and the utilization rate of the scanning device can be further improved.

[0019] In the embodiment of the present disclosure, the scanning body 11 may be a scanning body or a denture, etc.

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

[0021] Here, the angle of the angle-adjustable connection 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 inclined at a predetermined angle.

[0022] In addition, the scanning body 11 may be connected to the auxiliary features 12 on one or both sides, which is selected based on the specific application scenario.

[0023] Exemplarily, 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 screw thread, 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 bushing, 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 by a bushing.

[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, the auxiliary feature point 13 can uniquely identify one feature, that is, the auxiliary feature points 13 are set on the scanning body 11 and / or the auxiliary feature 12, and each auxiliary feature point 13 can uniquely identify a position feature corresponding to the scanning body 11 and / or the auxiliary feature 12. For example, the target feature a and the target feature b are set at position 1 on the scanning body 11 and position 2 on the auxiliary feature 12, respectively, the target feature a can uniquely identify the position feature at position 1 on the scanning body 11, and the 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 a positional feature corresponding to the scanning body 11 and / or auxiliary feature 12 may be used as an auxiliary feature point 13.

[0029] In the embodiments of the present disclosure, if the auxiliary feature is a spherical shape, 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 and color such as a circle, triangle, etc. is printed on the auxiliary feature 12 differently from the auxiliary feature 12; and if the auxiliary feature is a 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] Exemplarily, as shown in Figures 4a-4c, different shapes of auxiliary features 12 can further meet the intraoral scanning needs of different scenarios.

[0032] In an embodiment of the present disclosure, one scanning body 11 may further be connected to two auxiliary features 12, 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 rotatably connected to the implant body, so that the scanning body 11 can be controlled to rotate around an axis, and thus, when the auxiliary features 12 contact each other, the scanning body 11 can be controlled to rotate around an axis, thereby connecting multiple scanning bodies 11 by methods such as abutment and overlapping, thereby improving the accuracy of intraoral scanning.

[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 target shaped features 13 on the two auxiliary features 12 by mating with the auxiliary features 12 on the adjacent intraoral scanning rod.

[0036] In some embodiments, two scanning bodies corresponding to two auxiliary features are connected by connecting two auxiliary features, and auxiliary features of different lengths or multiple auxiliary features whose lengths can be overlapped 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 sphere shape, a code, and a mark based on the needs of the application scene, and the auxiliary feature points 13 are used to obtain 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 positioning accuracy of intraoral scanning can be further improved by the coordinate information of the auxiliary feature points 13, so that during the intraoral scanning process, images of different viewing angles of the oral cavity can be obtained through the scanning window, and in order to avoid the problem of accuracy reduction caused by subsequent data stitching errors, it is necessary to control the distribution distance between the auxiliary feature points 13 to be smaller than a preset distance threshold during installation, so as to ensure that the number of the auxiliary feature points 13 in the image obtained through the scanning window is greater than a preset number threshold, thereby ensuring the accuracy of intraoral scanning. Here, the distance threshold and number threshold can be adjusted in real time according to the needs for accuracy in different application scenarios, and the embodiment of the present disclosure is not particularly limited.

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

[0040] Specifically, the intraoral scanner scans the target intraoral cavity, acquires multiple frames of images, and transfers the images to a 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 set of points of the target oral cavity in the same coordinate system, and three-dimensional coordinate measurements of target features;

[0042] Obtain a preset model of the intraoral scanning rod, the preset model including a 3D coordinate true value of the target feature and a real point set (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, the method may be performed by a scanning device connection device, where the device may be implemented using software and / or hardware, and may be generally 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 area refers to the area of ​​the teeth in the oral cavity, and different users' oral cavity areas are different, and it should be understood that the oral cavity area is analyzed in advance to determine the position of each implant body, and the scanning bodies are connected to the implant bodies, so that 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 in a separate manner, 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 a target length corresponding to each auxiliary feature is stored in advance, for example, target auxiliary feature a1 is 2 millimeters, and target auxiliary feature a2 is 3 millimeters, and thus, 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 further 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, any two target auxiliary features are connected according to a preset connection manner.

[0051] Specifically, when the total length of the distance between two stored target auxiliary features is greater than a fixed distance, in the embodiment 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 of one scenario, as shown in Fig. 6a, two scanning bodies are connected through two target auxiliary features, thereby realizing the connection of multiple scanning devices, and the relative positional relationship between the scanning devices can be maintained, and a rigid body can be formed after the scanning rod is attached in the mouth, and it will not be deformed due to the deformation of soft tissue such as the gums, thus improving the accuracy of intraoral scanning. Here, preferably, the shapes of multiple scanning devices are different so that the scanner can be easily identified, and if the shapes of multiple scanning devices are the same, it may increase the difficulty of the algorithm. As shown in Fig. 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, and the positions of the two correspond one-to-one.

[0053] The connection means of the scanning device provided by the embodiment of the present disclosure obtains a fixed distance between each scanning body in the oral cavity region, and determines a target auxiliary feature of a target length according to the fixed distance, thereby connecting each scanning body with the target auxiliary feature in the oral cavity region. Using the above technical solution, the intraoral cavity can be directly scanned through the intraoral scanner to obtain the 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 is used to acquire a fixed distance between each scanning body in the oral cavity region; and a determination module 302 adapted 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 further comprises: and an adjustment module, which is used to connect any two of the target auxiliary features according to a preset connection method when the total distance between any two of the target auxiliary features is greater than the fixed distance.
