[0047] It is noted that the illustrations can only be schematic and that all details thereof are intended to be exemplary only, and do not limit the scope of the application.

[0048] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0051] In order to reduce the weight of the scanner, a frame of the scanner can be made of a light carbon fiber material. However, the carbon fiber material is easy to break under stress, and is usually assembled into a connecting frame by a plurality of carbon fiber plates and metal parts. The marker point module is fixedly connected by the metal parts in the connecting frame. The plurality of carbon fiber plates and metal parts are assembled, which is time-consuming and laborious. The connecting frame is manually assembled by the carbon fiber plates and metal parts, so that the overall structure stability of the assembled scanner is not high, which is not conducive to the accurate scanning of the scanner. Based on this, the embodiments of the present application provide a scanner which does not need to be assembled complicatedly in use, a tracking three-dimensional scanner comprising the scanner, and an integrated connecting frame applied to the scanner. The scanner, the tracking three-dimensional scanner and the connecting frame provided by the embodiments of the present application will be described and explained in combination with FIGS. 1-15.

[0052] As shown in FIG. 1, the scanner 100 provided by an embodiment of the present application comprises a frame 10 and a plurality of marker point modules 20. The frame 10 is configured as an integrated structure, and a plurality of connecting parts 30 are embedded in the frame 10. The plurality of marker point modules 20 correspond to at least part of the connecting parts 30, and are respectively assembled on the frame 10 by the corresponding connecting parts 30. The marker point module 20 is used to be recognized by a tracker.

[0053] The frame 10 is set as an integrated structure, and a plurality of connecting parts 30 are embedded in the frame 10, so as to position and install the constituent parts in the scanner 100. The constituent parts such as the plurality of marker point modules 20 can be fixed on the frame 10 by the corresponding connecting parts 30, instead of being directly fixed on the frame 10. The frame 10 can be integrally formed by a material such as carbon fiber which has a light quality. Therefore, the scanner 100 provided by the embodiments of the present application does not need to be spliced for a long time, and the overall structure stability of the scanner 100 is high.

[0054] In some embodiments, the plurality of marker point modules 20 correspond to at least part of the connecting parts 30, that is, all of the connecting parts 30 can be used to fix and install the marker point modules 20, or part of the connecting parts 30 can be used to install and fix the marker point modules 20, and the other part can be used to fix and install other constituent parts in the scanner 100. The plurality of marker point modules 20 correspond to at least part of the connecting parts 30, that is, one marker point module 20 can correspond to one connecting part 30, or one marker point module 20 can correspond to a plurality of connecting parts 30. The marker point module 20 is assembled on the frame 10 by the fixed connection with the corresponding connecting part 30. The frame 10 will not bear a large force due to the fixation of the marker point module 20, so as not to be easily broken. The marker point module 20 comprises at least one marker point which can be recognized by the tracker. The tracker determines the attitude information of the scanner 100 in the scanning process based on the recognition result of the marker point.

[0055] In some embodiments, the frame 10 of the integral structure is formed by using carbon fiber material, so that the frame 10 is light in weight, and the sense of comfort of the scanner 100 when holding is improved.

[0056] Please continue to refer to FIG. 1, the frame 10 can enclose a containing space, that is, the containing space is the area defined by the frame 10. A plurality of marker point modules 20 are respectively arranged on the periphery of the frame 10, so as to be recognized by the tracking instrument. Among them, the periphery refers to the periphery of the containing space enclosed by the frame 10.

[0057] In some embodiments, the containing space enclosed by the frame 10 can have an opening, so that some components of the scanner 100 are arranged in the containing space based on the opening, thereby reducing the volume of the scanner 100.

[0058] In some embodiments, the plurality of connecting members 30 are respectively pre-embedded members in the integral forming process of forming the frame 10, that is, the plurality of connecting members 30 are respectively pre-embedded in the frame 10 through the integral forming process. As shown in FIG. 2, when the frame 10 is integrally formed in the mold, the connecting member 30 can be pre-placed in the mold, so that the connecting member 30 can be integrally prepared with the frame 10, which can make the combination between the connecting member 30 and the frame 10 more closely and firmly, and is beneficial to improve the overall stability of the scanner 100.

[0059] In some embodiments, the connecting member 30 can be formed by using a material with good ductility, for example, the connecting member 30 can be a metal connecting member. When the marker point module 20 and other components are fixed to the frame 10 through the connecting member 30, the connecting member 10 is not easy to be damaged due to the external force borne in the installation process of each component, which is beneficial to improve the stability of the scanner 100.

[0060] Please continue to refer to FIG. 1 and FIG. 2, the frame 10 includes a plurality of connecting struts 11, and a plurality of connecting members 30 are embedded between the plurality of connecting struts 11. That is, the connecting struts 11 are respectively connected between two adjacent connecting members 30. Among them, the frame strut 11 can be a hollow structure. That is, the frame 10 of this embodiment can be connected by the hollow connecting struts 11. Based on the hollow structure characteristics of the connecting struts 11, the bending resistance of the frame strut 11 can be improved to improve the structural strength of the frame 10, and the weight of the frame 10 can also be reduced. Of course, in some embodiments, the connecting struts 11 can also be filled with light materials, such as foamed materials arranged in the connecting struts 11.

[0061] In some embodiments, the connecting struts 11 can be configured as carbon fiber square tubes or carbon fiber round tubes, and the number and arrangement of the connecting struts 11 can be specifically configured according to the use requirements of the frame 10. For example, one connecting member 30 can be connected with multiple connecting struts 11 to be connected with other connecting members 30 around through the connecting struts 11, which is conducive to the stability of the scanner 100 and facilitates the arrangement of the marker point modules 20 at multiple angles so that the tracker can track the postures of the scanner 100 at different angles.

[0062] It should be noted that the connecting struts 11 constituting the frame 10 are not limited to the hollow structure shown in the drawings. In other embodiments, the connecting struts 11 can also be configured as solid structures based on requirements. In addition, in other embodiments, in order to reduce the weight of the frame 10, the connecting struts 11 can also be configured as hollow structures.

[0063] Referring to FIGS. 1 and 2, in some embodiments, the connecting struts 10 can be configured as curved structures to enhance the compression resistance and improve the stability of the frame 10.

[0064] In some embodiments, the multiple connecting struts 10 are respectively circular arc structures located on the same virtual sphere to improve the stability of the frame 10 and facilitate the uniform arrangement of the multiple marker point modules 20 on the frame 10 for identification by the tracker. Here, the virtual sphere is not a real sphere, but is used to illustrate the structural and positional relationship between the multiple connecting struts 11.

[0065] In some embodiments, the circular arc angles of the connecting struts 11 between any two adjacent marker point modules 20 in the multiple marker point modules 20 are equal to each other. That is, the multiple marker point modules 20 on the scanner 100 are uniformly arranged on the periphery of the frame 10, so that the identification of the marker point modules 20 on the scanner 100 by the tracker is facilitated. Of course, in other embodiments, the multiple marker point modules 20 can also be arranged on the frame 10 in other ways, which will not be described here.

[0066] In some embodiments, the connecting members 30 corresponding to the respective marker point modules 20 are located at the corresponding vertices of the same virtual regular polyhedron. Since the plurality of marker point modules 20 are fixed to the frame 10 by the corresponding connecting members 30, the plurality of marker point modules 20 assembled on the frame 10 by the corresponding connecting members 30 are also located at the corresponding vertices of the same virtual regular polyhedron, so as to realize the uniform distribution of the plurality of marker point modules 20 on the periphery of the frame 10. Based on this, the number of marker point modules 20 that can be sensed by the tracker at different angles is basically consistent, which facilitates the tracker to accurately obtain the pose of the scanner 100. The virtual regular polyhedron structure is not a real structure existing in the scanner 100, but is used to illustrate the positional relationship between the respective connecting members 30 corresponding to the marker point modules 20, that is, to illustrate that the plurality of marker point modules 20 are uniformly fixed to the frame 10 by the corresponding connecting members 30 according to the regular polyhedron vertex layout rule.

[0067] In some embodiments, the virtual regular polyhedron is an icosahedron as shown in FIG. 3, so that five marker point modules 20 can be seen from different angles. In other embodiments, the virtual regular polyhedron can also be a tetrahedron, a hexahedron, an octahedron, or a dodecahedron. It should be noted that the connecting members 30 corresponding to the marker point modules 20 are arranged on at least part of the vertices of the same virtual regular polyhedron, that is, the marker point modules 20 can cover the vertices of the virtual regular polyhedron, or can be arranged on only part of the vertices of the virtual regular polyhedron.

[0068] In some embodiments, the structure diagram of the scanner 100 formed by arranging the plurality of marker point modules 20 on the frame 10 according to the regular polyhedron vertex layout rule can be as shown in FIG. 4. In this embodiment, the frame 10 is a spherical structure with relatively high stability, and the plurality of marker point modules 20 are uniformly distributed on the spherical surface formed by the frame 10, so that the same number of marker point modules 20 can be observed by the tracker from different angles.

[0069] In some embodiments, the scanning module in the scanner 100 can be arranged inside the accommodating space enclosed by the frame 10, or arranged outside the accommodating space, or partially arranged inside the accommodating space and partially arranged outside the accommodating space. The scanning module includes a laser module 50 for emitting laser to the scanning object and a camera module 60 for collecting image information of the scanning object. The number of the camera module 60 is two, and the two camera modules 60 are fixed on a skeleton 61. The laser module 50 can also be fixed on the skeleton 61, that is, the laser module 50 and the two camera modules 60 are respectively fixed by the skeleton 61 and fixedly connected with the corresponding connecting piece 30 by the skeleton 61, so as to realize the fixed connection between the scanning module and the frame 10. The connecting rods 11 of the frame 10 form gaps therebetween, so that the laser module 50 arranged inside the accommodating space enclosed by the frame 10 can emit laser to the scanning object and / or the camera module 60 can collect the image information of the scanning object.

[0070] Please continue to refer to FIG. 1 and FIG. 5 to FIG. 8, in some embodiments, at least one marker point module 20 is connected with the corresponding connecting piece 30 through the intermediate piece 302. The scanner 100 further includes a foot support 40 connected with the intermediate piece 302, and the foot support 40 is used for supporting the scanner 100 on a placement position. In some embodiments, each intermediate piece 302 is connected with the foot support 40. Alternatively, in some embodiments, only part of the intermediate pieces 302 are connected with the foot support 40. Of course, in some embodiments, a preset gap 340 can be formed between the foot support 40 and the corresponding marker point module 20. Based on this, the scanner 100 provided by the embodiments of the present application can be directly placed on a placement position such as the ground by the foot support 40, and is convenient to use. In addition, the foot support 40 and the corresponding marker point module 20 have the preset gap 340, so that when the placed scanner 100 is supported by the foot support 40, the displacement of the corresponding marker point module 20 due to the force of the foot support 40 can be avoided, and the accuracy of the assembly position of the marker point module 20 on the frame 10 is ensured, and the deformation of the foot support 40 after being stressed will not adversely affect the corresponding marker point module 20. The corresponding marker point module 20 of the foot support 40 refers to the marker point module 20 connected with the foot support 40 on the same intermediate piece 302.

[0071] In some embodiments, the intermediate piece 302 can be an integral structure with the module shell of the marker point module 20. Specifically, the intermediate piece 302 and the module shell of the marker point module 20 are integrally formed, which is convenient for processing and manufacturing. Of course, in some embodiments, the intermediate piece 302 and the marker point module 20 are designed in a split type, and are further fixedly connected. For example, the intermediate piece 302 and the marker point module 20 can be fixedly connected by screws, buckles or adhesion.

[0072] In some embodiments, the foot props 40 are connected to the corresponding connecting members 30 via the intermediate pieces 302 and the corresponding marker point modules 20, so that a special base designed to support the scanner 100 can be omitted, which is conducive to reducing the weight of the scanner 100 and facilitating use. However, in other embodiments, the foot props 40 can also be connected to the corresponding connecting members 30 via other components or directly connected to the corresponding connecting members 30, which will not be described one by one here.

[0073] In some embodiments, the intermediate piece 302 is provided with an extension protruding column 31 at one end away from the frame 10, and the other end of the intermediate piece 302 is fixedly connected to the corresponding connecting member 30. The extension protruding column 31 penetrates through the corresponding marker point module 20 to fix the corresponding marker point module 20. The extension protruding column 31 penetrating through the corresponding marker point module 20 is connected to the foot prop 40 to fix the foot prop 40 on the intermediate piece 302, and a predetermined gap 340 is formed between the foot prop 40 and the corresponding marker point module 20. By penetrating the corresponding marker point module 20 through the extension protruding column 31 and then protruding a certain height relative to the marker point module 20, and then fixedly connecting the foot prop 40 with the protruding part, it can be ensured that the foot prop 40 and the corresponding marker point module 20 can form a predetermined gap 340, which is conducive to improving the stability of the scanner 100, and the implementation is simple.

[0074] In some embodiments, the intermediate piece 302 is provided with a plurality of extension protruding columns 31, and the plurality of extension protruding columns 31 are respectively penetrated through the corresponding marker point modules 20 and then respectively fixedly connected to the foot props 40, which is conducive to improving the stability of the foot props 40 and facilitating to improve the supporting force of the foot props 40 on the scanner 100.

[0075] In some embodiments, the foot prop 40 can be fixedly connected to the extension protruding column 31 penetrating through the corresponding marker point module 20 based on the screw 301, which is firm and reliable in connection. For example, one end of each intermediate piece 30 can be provided with three extension protruding columns 31, and each extension protruding column 31 is fixedly connected to the corresponding foot prop 40 via the screw 301 after penetrating through the corresponding marker point module 20.

[0076] In some embodiments, the foot prop 40 can be made of plastic to have a lighter weight, which is conducive to achieving the lightweight design requirement of the scanner 100.

[0077] In some embodiments, the number of foot props 40 can be set to three, and the corresponding three marker point modules 20 of the three foot props 40 are adjacent to each other. That is, the three foot props 40 are arranged in a triangular shape, so that the stability of the foot props 40 supporting the scanner 100 can be improved.

[0078] In some embodiments, the marker point module 20 is in a ball-and-plate structure. The plate surface of the ball-and-plate structure corresponding to the marker point module 20 is provided with one or more marker points identifiable by the tracking device, and the outer peripheral wall of the ball-and-plate structure is provided with a plurality of marker points distributed in the circumferential direction.

[0079] In some embodiments, the diameter of the outer peripheral wall of the ball-and-plate structure increases in the direction towards the frame 10, and the large end of the outer peripheral wall of the ball-and-plate structure can also be provided in a wavy structure, which is beneficial for the identification of the tracking device, so as to improve the scanning accuracy and flexibility of the scanning object. The outer periphery of the plate surface of the ball-and-plate structure can be provided with a hollow structure, so as to reduce the weight of the marker point module 20, and facilitate the lightweight design of the scanner 100.

[0080] In some embodiments, the foot support 40 includes a support plate 41 and a support foot 42 provided on the support plate 41. The support plate 41 is arranged opposite to the plate surface of the ball-and-plate structure corresponding to the marker point module 20 with a preset gap 340, and the support foot 42 is located on the side of the support plate 41 away from the aforementioned plate surface. When the scanner 100 is placed in the placement position by the foot support 40, the support foot 42 is supported on the placement position. The support feet 42 of the aforementioned three foot supports 40 are respectively protruded relative to the corresponding support plates 41 for support. The foot support 40 is provided with the protruded support foot 42 on only one side, so as to reduce the weight of the foot support 40. The support feet 42 of the three foot supports 40 are arranged in a triangular shape, so as to increase the stability of the placement of the scanner 100.

[0081] As shown in FIG. 1, the scanner 100 further includes a handle 12, and at least one of the plurality of connecting members 30 corresponds to the handle 12 for fixing the handle 12. The handle 12 is fixedly connected to the frame 10 by the corresponding connecting member 30, so that the influence of the force of the handle 12 on the frame 10 can be avoided, and the frame 10 is not easy to break.

[0082] In some embodiments, the center of gravity of the scanner 100 is arranged to fall on the handle 12. By using the action and reaction forces, the user feels that the force of the scanner 100 is more balanced when holding the handle 12, so as to improve the holding experience of the user when holding the scanner 100.

[0083] In some embodiments, the center of gravity of the scanner 100 falls on the part of the handle 12 for the hand to hold, so that the user has a better holding experience when holding the handle 12.

[0084] In some embodiments, the handle 12 is arranged in the containing space surrounded by the frame 10 and is fixedly connected to the frame 10 by the corresponding connecting member 30, which is beneficial for reducing the volume of the scanner 100. The containing space surrounded by the frame 10 is open, so that the user can reach into the containing space through the opening to hold the handle 12.

[0085] Referring to FIG. 1, the laser module 50 is fixed to the frame 10 by at least one connecting member 30, so as to be supported by the frame 10. In some embodiments, the laser module 50 is fixed to the outside of the accommodating space surrounded by the frame 10 by the corresponding connecting member 30, so as to scan the scanning object. Since the laser module 50 is fixed to the corresponding connecting member 30, the fixing process will not generate a large impact force on the frame 10, so as not to easily cause the fracture of the frame 10, so that the frame 10 has higher stability, and the laser module 50 fixed thereto can accurately scan the laser to the scanning object, so as to improve the scanning accuracy of the scanning object. However, in other embodiments, the laser module 50 can also be fixed to the inside of the accommodating space surrounded by the frame 10 by the corresponding connecting member 30, so as to reduce the volume of the scanner 100.

[0086] In some embodiments, the skeleton 61 for installing the two camera modules 60 of the scanner 100 is fixed to the frame 10 by at least one corresponding connecting member 30, so as to accurately collect the image information of the scanning object based on the frame 10 of the integrated structure. The skeleton 61 can be arranged on the periphery of the accommodating space surrounded by the frame 10, so as to collect the image of the scanning object by the two camera modules 60, or can be arranged in the accommodating space, so as to reduce the volume of the scanner 100.

[0087] In some embodiments, the laser module 50 can be individually fixed to the frame 10 based on the corresponding connecting member 30, or can be fixed to the skeleton 61, so as to be connected with the camera module 60 through the skeleton 61 and the corresponding connecting member 30, and be fixed to the frame 10. It should be noted that the arrangement mode of the laser module 50 and the camera module 60 is not particularly limited in the present application, for example, the laser module 50 and the two camera modules 60 can be arranged on the frame 10 along the first direction, or can be arranged on the frame 10 along the second direction. The first direction is the direction in which the foot support 40 provides support force in the placed position of the scanner 100, for example, the scanner 100 is supported on the ground by the foot support 40, and the first direction is the direction perpendicular to the ground. The second direction can be but not limited to the direction perpendicular to the first direction. The laser module 50 can be arranged between the two camera modules 60, so that the two camera modules 60 can collect more effective image information of the scanning object.

In some embodiments, the number of the openings 511 can be multiple and correspond to the laser emitters of the laser module 50. In some embodiments, the number of the openings 511 can be one, and the laser emitters of the laser module 50 emit laser through the opening 511. Therefore, the protective cover 51 can protect the laser module 50 and will not affect the normal scanning of the scanning object.

[0089] In some embodiments, the protective cover 51 can be arranged with a plurality of marker points 512 along the circumferential direction thereof for the tracker to identify. The protective cover 51 can protect the laser module 50 and serve as a carrier of the marker points identifiable by the tracker, so as to achieve the same marking function as the marker point module 20. Therefore, based on the protective cover 51 provided with the marker points 512, one marker point module 20 and the corresponding connecting piece 30 of the marker point module 20 can be reduced, which is conducive to simplifying the structure of the scanner 100 and reducing the weight of the scanner 100.

[0090] In some embodiments, the protective cover 51 provided with the marker points 512 is located at the vertex of the aforementioned virtual polyhedron together with the plurality of marker point modules 20, which is convenient for the tracker to identify.

In this embodiment, the frame 10 is provided with two reserved gaps 110 corresponding to the two camera modules 60 to avoid the frame 10 from blocking the collection lines of sight of the two camera modules 60, i.e., the two camera modules 60 collect the image information of the scanning object through the corresponding reserved gaps 110.

[0092] In some embodiments, at least part of the camera module 60 is accommodated in the corresponding reserved gap 110. Then the camera module 60 can be limited through the corresponding reserved gap 110 to reduce or avoid the phenomenon of position deviation of the camera module 60 in the use process, effectively improving the collection accuracy. That is, at least part of the two camera modules 60 is accommodated in the reserved gap 110 of the frame 10, so that the scanner 100 as a whole is more compact in appearance, has better stability, and is more aesthetic.

At least part of the camera modules 60 extends out of the accommodating space through the corresponding reserved gap 110 to accurately collect image information of the scanning object.

[0094] In some embodiments, the skeleton 61 can be arranged in the accommodating space surrounded by the frame 10 first to be connected with the corresponding connecting member 30, and then the two camera modules 60 are respectively inserted into the accommodating space through the corresponding reserved gap 100 to be fixedly mounted on the corresponding positions of the skeleton 61, so as to realize the fixed mounting of the camera modules 60.

[0095] In some embodiments, the skeleton 61 is fixed to the frame 10 through at least one connecting member 30, and the connecting member 30 can have an inner side facing the accommodating space and an outer side facing away from the accommodating space; the skeleton 61 is fixedly connected with the inner side of the connecting member 30, so that the two camera modules 60 respectively collect image information of the scanning object through the corresponding reserved gap 110. Specifically, the inner side of the connecting member 30 can be provided with a threaded hole to fix the skeleton 61 and the threaded hole of the connecting member 30 by a screw. Of course, the fixing mode between the connecting member 30 and the skeleton 61 is not limited to the screwing mode, but can also be welding or bonding, etc., which can be selected by those skilled in the art according to the actual situation, and will not be described here.

[0096] Continuing to refer to FIGS. 9 and 10, in some embodiments, the skeleton 61 and the laser module 50 are respectively fixed on two sides of the same connecting member 30. Among them, the laser module 50 is located on the outer side of the accommodating space surrounded by the frame 10, preferably, the laser module 50 is located outside the accommodating space, and the skeleton 61 is located on the inner side of the accommodating space. In some embodiments, the skeleton 61 is located inside the accommodating space. That is, in the present embodiment, the same connecting member 30 is provided with a connecting portion on both sides inside and outside the accommodating space to connect the skeleton 61 and the laser module 50, respectively. Using the same connecting member 30 to fixedly connect the laser module 50 and the skeleton 61 can reduce the number of connecting members 30, facilitate the simplification of the structure of the scanner 100, and reduce the weight of the scanner 100.
