[0063] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0064] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application.

[0065] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0066] Please refer to Figure 1-Figure 4 As shown, an embodiment of the present application provides a three-dimensional scanning device, which includes a support platform 40, at least two optical components 10, 20, 30 and a controller (not shown in the figure), the support platform 40 is used to support the scanned object (not shown in the figure), at least two optical components 10, 20, 30 are arranged at intervals around the support platform 40, and are used to scan the scanned object, and the controller is used to control the rotation of the optical component or the support platform 40. Therefore, the three-dimensional scanning device of the embodiment of the present application can scan the object to obtain a three-dimensional image and three-dimensional data about the scanned object. Among them, at least two optical components 10, 20, 30 are arranged at intervals around the support platform 40 to ensure the integrity of the collected image and improve the scanning effect and scanning speed of the three-dimensional scanning device; the controller controls the optical component or the support platform 40 to rotate, further improve the scanning speed of the three-dimensional scanning device, and realize fast and stable three-dimensional scanning. The at least two optical components 10, 20, 30 described in the embodiment of the present application specifically refer to the optical components including at least two, which are any combination of the optical components 10, 20 and 30, including a combination of the same optical components or a combination of different optical components or a combination of partially the same optical components.

[0067] The supporting platform 40 may be a disc-shaped structure, so as to facilitate supporting the scanned object.

[0068] In addition, the scanned object can be a human body, a work of art, an industrial design, etc.

[0069] Optionally, see Figure 5 As shown, at least two optical components 10, 20, 30 may include a first optical component 10, and the first optical component 10 includes: a telescopic member 12; a first optical unit connected to the telescopic member 12, and used to obtain image data of the scanned object; wherein the first optical unit includes at least two image acquisition components 13, and the telescopic member 12 can drive at least one image acquisition component 13 to be at least two positions along a first direction X. The first direction X may be the height direction of the optical components 10, 20, 30 or a direction having an angle with the height direction. The following content of this article mainly introduces the first direction X by taking the height direction as an example.

[0070] When the user needs the first optical component 10 to perform optical work, the user can extend the telescopic member 12 along the first direction, so that at least one image acquisition component 13 connected to the telescopic member 12 moves along the first direction to the working position required by the user, so that the first optical unit performs the optical work required by the user. When the user does not need the first optical component 10 to perform optical work, the user can shrink the telescopic member 12 in the direction opposite to the first direction, so that at least one image acquisition component 13 connected to the telescopic member 12 moves to the storage position required by the user, that is, the length dimension of the first optical component 10 along the first direction becomes smaller, so that the volume of the first optical component 10 becomes smaller. Under this setting, the first optical component 10 with a smaller volume has a higher degree of maneuverability, which is convenient for the user to carry the first optical component 10, and the first optical component 10 with a smaller volume occupies less space, which is convenient for the user to store, place or store the first optical component 10, and the user has a higher user experience.

[0071] In addition, the telescopic member 12 may change its length along the first direction X by changing its shape and / or structure. The following content of this article will introduce the possible structure of the telescopic member 12 in detail.

[0072] Furthermore, the first optical unit includes at least two image acquisition components 13, which can be optical instruments such as depth sensors, cameras, projectors, light wave transmitters, light wave receivers or optical zoomers. The optical work that can be completed by the image acquisition component 13 can be photography, projection, scanning, light wave transmission or light wave reception.

[0073] In addition, the embodiment of the present application does not limit the number of image acquisition components 13 that can be set, and the user can set a corresponding number of image acquisition components 13 according to actual work needs.

[0074] Optionally, the telescopic member 12 includes at least a first bracket 121 and a second bracket 122 , the first bracket 121 and the second bracket 122 are slidably connected, and when the telescopic member 12 is extended along the first direction X, at least part of the first bracket 121 is located above the second bracket 122 .

[0075] The user can slide the first bracket 121 relative to the second bracket 122 along the first direction X to extend the telescopic member 12 along the first direction X, or the user can slide the first bracket 121 relative to the second bracket 122 in the direction opposite to the first direction X to retract the telescopic member 12 in the direction opposite to the first direction X. The above operations can change the position of the image acquisition component 13 disposed on the first bracket 121 along the first direction X, and change the volume of the first optical component 10. The telescopic member 12 formed by the sliding connection of the first bracket 121 and the second bracket 122 has a low structural complexity, is easy to manufacture, easy to assemble, and has a high degree of working reliability.

[0076] In addition, either the first bracket 121 or the second bracket 122 may include a sliding rod (not shown in the figure), and the other may be provided with a sliding hole (not shown in the figure), and at least a portion of the sliding rod may be located in the sliding hole, so that the first bracket 121 and the second bracket 122 are slidably connected. Alternatively, either the first bracket 121 or the second bracket 122 may include a sliding portion (not shown in the figure), and the other may be provided with a sliding groove (not shown in the figure), and at least a portion of the sliding portion may be located in the sliding groove, so that the first bracket 121 and the second bracket 122 are slidably connected. In detail, both the first bracket 121 and the second bracket 122 may be structures extending along the first direction X.

[0077] Furthermore, a portion of the image acquisition component 13 can be set at an end of the first bracket 121 away from the second bracket 122, and / or, another portion of the image acquisition component 13 can be set at any position between the two ends of the first bracket 121 that are relatively set along the first direction X.

[0078] In addition, the optical axis (the line of the center of the optical lens) of the image acquisition component 13 disposed on the first bracket 121 may be perpendicular to the first direction X or may have an acute angle or an obtuse angle with the first direction X. Accordingly, the image acquisition component 13 disposed on the first bracket 121 may be rotatably connected to the first bracket 121, so that the user can adjust the direction of the optical axis of the image acquisition component 13 disposed on the first bracket 121. Of course, the optical axis of the image acquisition component 13 disposed on the second bracket 122 may be perpendicular to the first direction X or may have an acute angle or an obtuse angle with the first direction X. Accordingly, the image acquisition component 13 disposed on the second bracket 122 may also be rotatably connected to the second bracket 122, so that the user can adjust the direction of the optical axis of the image acquisition component 13 disposed on the second bracket 122.

[0079] Furthermore, the image acquisition component 13 disposed on the first bracket 121 can be slidably connected to the first bracket 121, so that the user can adjust the relative position of the image acquisition component 13 disposed on the first bracket 121 and the first bracket 121. Of course, the image acquisition component 13 disposed on the second bracket 122 can be slidably connected to the second bracket 122, so that the user can adjust the relative position of the image acquisition component 13 disposed on the second bracket 122 and the second bracket 122.

[0080] In other embodiments, the telescopic member 12 may further include a third bracket (not shown) slidably connected to the second bracket 122 to form a two-stage telescopic structure, and accordingly, the image acquisition component 13 may be disposed on the third bracket. Alternatively, the telescopic member 12 may be a telescopic structure of three or more levels. The following content of this article is mainly described by taking the telescopic member 12 including the first bracket 121 and the second bracket 122 as an example.

[0081] Optionally, the first bracket 121 is provided with at least two image acquisition components 13 spaced apart along the first direction X. Under this arrangement, the optical working range of the first optical component 10 is relatively large.

[0082] Optionally, the second bracket 122 is also provided with at least two image acquisition components 13 spaced apart along the first direction X. Under this arrangement, the optical working range of the first optical component 10 is also relatively large.

[0083] The following content of this article mainly describes the example that the first bracket 121 and the second bracket 122 are both provided with at least two image acquisition components 13 spaced apart along the first direction X. Under this setting, if the image acquisition component 13 is a camera, and if the work that the image acquisition component 13 can perform is optical scanning, the optical scanning range of the first optical component 10 of this embodiment is large, so that the human body, artwork or industrial design can be scanned. The embodiment of the present application is not limited to the spacing distance between each two image acquisition components 13.

[0084] In other embodiments, at least a portion of the telescopic member 12 may be a bellows structure, or at least a portion of the telescopic member 12 may be a diamond four-bar structure, which structures may also allow the telescopic member 12 to have a telescopic property.

[0085] The following content of this article is mainly described by taking the sliding connection between the first bracket 121 and the second bracket 122 to form the telescopic member 12 as an example.

[0086] Optionally, one of the first bracket 121 and the second bracket 122 includes a first locking portion (not shown in the figure), and the other includes a second locking portion (not shown in the figure), and the first locking portion (not shown in the figure) can be locked and connected with the second locking portion (not shown in the figure). Under this setting, the position of the first bracket 121 relative to the second bracket 122 can be fixed, so that the position of the image acquisition component 13 disposed on the first bracket 121 relative to the second bracket 122 can be fixed, so that the image acquisition component 13 disposed on the first bracket 121 can reliably complete the optical work required by the user.

[0087] Wherein, either the first locking portion or the second locking portion may be a protruding structure, and the other may be a recessed structure, and at least a portion of the protruding structure may be located in the recessed structure, thereby forming a locking connection between the first locking portion and the second locking portion. Alternatively, either the first locking portion or the second locking portion may be a rod structure, and the other may be a hole structure, and at least a portion of the rod structure may be located in the hole structure, thereby forming a locking connection between the first locking portion and the second locking portion. Alternatively, either the first locking portion or the second locking portion may be a plane structure, and the other may be a threaded member, and the threaded member may be rotated to increase the static friction between the threaded member and the plane, thereby forming a locking connection between the first locking portion and the second locking portion.

[0088] In addition, the embodiment of the present application does not limit the number of the first locking part and the number of the second locking part. For example, the first locking part and the second locking part can both be one; or the first locking part can be one and the second locking part can be at least two; or the second locking part can be one and the first locking part can be at least two; or the first locking part can be at least two and the second locking part can also be at least two. When the number of at least one of the first locking part and the second locking part is at least two, the first bracket 121 can be fixed at at least two positions along the first direction X relative to the second bracket 122.

[0089] Optionally, the first optical assembly 10 further includes a driving member (not shown in the figure), which can drive the telescopic member 12 to extend or retract along the first direction X. Under this setting, the driving member can reduce the user's operating intensity. Secondly, the control accuracy of the driving member is high, and the telescopic size of the telescopic member 12 along the first direction X can be accurately controlled, and the user's use experience is high.

[0090] The driving member may be a motor, a hydraulic press or a pneumatic press, and the driving member may be arranged on the second bracket 122, and the driving member may directly drive the second bracket 122, or the driving member may transmit the driving force to the second bracket 122 through at least one of gear meshing, pulleys and cables.

[0091] In other embodiments, the first optical component 10 may not include a driving member, that is, the user may manually operate the telescopic length of the telescopic member 12 along the first direction X.

[0092] Optionally, see Figure 6-Figure 8 As shown, in another embodiment, the first optical assembly 10 includes a body 11, a telescopic member 12 and a first optical unit, the telescopic member 12 is connected to the body 11; the first optical unit is connected to the telescopic member 12; the first optical unit includes at least two image acquisition components 13, and the telescopic member 12 can drive at least one image acquisition component 13 to be in at least two positions along the first direction X (for example Figure 6 The positions shown and Figure 7 The telescopic member 12 can drive at least one image acquisition component 13 to be at least two positions relative to the body 11 along the first direction X. The telescopic member 12 and the first optical unit of the first optical assembly 10 have the above-mentioned structures and technical effects, which will not be repeated here.

[0093] Please refer to Figure 7 As shown, when the user needs the first optical component 10 to perform optical work, the user can extend the telescopic member 12 along the first direction X, so that the image acquisition component 13 connected to the telescopic member 12 moves relative to the body 11 to the working position required by the user, so that the image acquisition component 13 performs the optical work required by the user. Figure 6As shown, when the user does not need the first optical component 10 to perform optical work, the user can retract the telescopic member 12 in the direction opposite to the first direction X, so that the image acquisition component 13 connected to the telescopic member 12 moves relative to the body 11 to the storage position required by the user, that is, the length dimension of the first optical component 10 along the first direction X becomes smaller, thereby reducing the volume of the first optical component 10. Under this setting, the first optical component 10 with a smaller volume has a higher degree of mobility, which is convenient for the user to carry the first optical component 10, and the first optical component 10 with a smaller volume occupies less space, which is convenient for the user to store, place or store the first optical component 10, and the user has a higher use experience.

[0094] The body 11 plays at least one of the following roles: installation and fixing, supporting, and protecting the telescopic member 12 and the image acquisition component 13. The following content of this article will introduce the possible structure of the body 11 in detail.

[0095] Optionally, see Figure 7-Figure 8 As shown, the telescopic member 12 at least includes a first bracket 121 and a second bracket 122 , the first bracket 121 and the second bracket 122 are slidably connected, and the second bracket 122 is connected to the body 11 .

[0096] The connection between the body 11 and the second bracket 122 can be a fixed connection, a rotational connection or a sliding connection. When the body 11 and the second bracket 122 are fixedly connected, the position of the second bracket 122 relative to the body 11 remains unchanged. When the body 11 and the second bracket 122 are rotationally connected, the user can change the angle of the second bracket 122 relative to the body 11, and accordingly, the user can change the angle of the first bracket 121 and the image acquisition component 13 disposed on the first bracket 121 relative to the body 11. When the body 11 and the second bracket 122 are slidingly connected, the second bracket 122 can slide relative to the body 11 along the first direction X so that the working range of the image acquisition component 13 disposed on the first bracket 121 is larger. The subsequent content of this article is mainly described by taking the fixed connection position of the body 11 and the second bracket 122 as an example.

[0097] Optionally, see Figure 6-Figure 7 As shown, the body 11 is a shell structure, and the body 11 is provided with a through hole 1111 , and the through hole 1111 is used to expose the image acquisition component 13 arranged in the body 11 .

[0098] Please refer to Figure 6As shown, when the telescopic member 12 is retracted, at least a portion of the image acquisition components 13 can be located in the housing 11 in a shell structure, so that the housing 11 protects at least a portion of the image acquisition components 13, reducing the possibility that at least a portion of the image acquisition components 13 are damaged by foreign objects outside the housing 11. Correspondingly, at least a portion of the structure of the telescopic member 12 can also be located in the housing 11 in a shell structure, reducing the possibility that at least a portion of the structure of the telescopic member 12 is damaged by foreign objects outside the housing 11. Please refer to Figure 7 As shown, when the telescopic member 12 is extended along the first direction X, a partial number of the image acquisition components 13 and a partial structure of the telescopic member 12 are located outside the body 11, and a portion of the image acquisition components 13 are located inside the body 11 and are exposed by the through hole 1111, so that the image acquisition components 13 located inside the body 11 can perform optical operations on the outside of the body 11 through the through hole 1111.

[0099] Among them, when the second bracket 122 is located in the body 11 and the second bracket 122 is provided with an image acquisition component 13, the through hole 1111 can be used to expose the image acquisition component 13 provided on the second bracket 122, and the number of through holes 1111 can correspond to the number of image acquisition components 13 provided on the second bracket 122, so that each image acquisition component 13 provided on the second bracket 122 is exposed by its corresponding through hole 1111.

[0100] In addition, an opening 1112 is provided at the top of the body 11, and the opening 1112 is used for the first bracket 121 to pass through, so that the first bracket 121 and the image acquisition component 13 provided on the first bracket 121 can move from the inside of the body 11 to the outside of the body 11, or so that the first bracket 121 and the image acquisition component 13 provided on the first bracket 121 can move from the outside of the body 11 to the inside of the body 11.

[0101] Optionally, the first optical component 10 further includes an angle detection member (not shown in the figure), which is disposed on at least one of the body 11, the telescopic member 12 and the image acquisition component 13. The angle detection member is used to detect the installation angle (for example, the angle relative to the horizontal plane) of at least one of the body 11, the telescopic member 12 and the image acquisition component 13, so that the user can confirm whether the installation angle of at least one of the body 11, the telescopic member 12 and the image acquisition component 13 meets the optical working angle requirements, and the user can adjust the installation angle of at least one of the body 11, the telescopic member 12 and the image acquisition component 13 according to the angle error detected by the angle detection member.

[0102] Optionally, see Figure 7As shown, the body 11 includes a main body 111 and a support body 112. The main body 111 is connected to the telescopic member 12. The telescopic member 12 can be extended or retracted relative to the main body 111 along the first direction X. The support body 112 is movably connected to the main body 111 so that the body 11 includes a storage state and an expanded state. In the storage state, at least part of the structure of the support body 112 is located inside the main body 111, and the first optical component 10 is relatively small, which is convenient for users to carry, store or store the first optical component 10, and the user experience is high. In the expanded state, at least part of the structure of the support body 112 is located outside the main body 111. The support body 112 is used to auxiliary support the main body 111, the telescopic member 12 and the image acquisition component 13, so that the first optical component 10 is not prone to shaking, so that the image acquisition component 13 can perform optical work accurately.

[0103] The body 111 may be a shell structure, and the body 111 may accommodate at least part of the structure of the telescopic member 12 and at least part of the number of image acquisition components 13. Accordingly, the body 111 may be provided with the through hole 1111 and the opening 1112 described above. The body 111 may also be provided with a storage groove 1113, and the storage groove 1113 is used to accommodate at least part of the structure of the support body 112. In detail, the body 11 may include at least two support bodies 112, and accordingly, the number of the storage grooves 1113 is the same as the number of the support bodies 112.

[0104] In addition, the movable connection between the support body 112 and the body 111 can be a rotation connection and / or a sliding connection, so that the position of the support body 112 relative to the body 111 can be adjusted. The support body 112 itself can have a rotation structure and / or a sliding structure, so that the size, shape and structure of the support body 112 itself can be changed.

[0105] In addition, the body 11 may further include a roller 113 connected to the bottom of the body 111, so that the user can push the first optical component 10, and the user's experience is high. The body 11 may further include a handle 114 connected to the side wall of the body 111, so that the user can carry the first optical component 10 by grasping the handle 114, and the user's experience is high.

[0106] The working process of the first optical component 10 in the embodiment of the present application is as follows:

[0107] The user can operate the support body 112 to move relative to the body 111, so that the support body 112 assists in supporting the body 111. Then, the user can operate the first bracket 121 to move relative to the second bracket 122, so that the first bracket 121 and the image acquisition component 13 disposed on the first bracket 121 move from the inside of the body 11 to the outside of the body 11. Then, the user locks the first bracket 121 and the second bracket 122 to fix the position of the image acquisition component 13 disposed on the first bracket 121 relative to the second bracket 122. Furthermore, the user can adjust the angle of the first optical component 10 according to the angle detector.

[0109] In addition, the support member 22 may change its length along the first direction X by changing its shape and / or structure. The following content of this article will introduce the possible structure of the support member 22 in detail.

[0110] Optionally, the support member 22 at least includes an upper bracket 221 and a lower bracket 222, and the upper bracket 221 and the lower bracket 222 are foldably connected or detachably connected so that the support member 22 includes a stored state and an unfolded state.

[0111] Optionally, see Fig.11 As shown, when the user needs the second optical component 20 to perform optical work, the user can make the support member 22 unfold along the first direction X, so that the image acquisition component 23 connected to the support member 22 moves to the working position required by the user, so that the image acquisition component 23 performs the optical work required by the user. Fig.10 As shown, when the user does not need the second optical component 20 to perform optical work, the upper bracket 221 and the lower bracket 222 are foldably connected, and the user can fold the upper bracket 221 toward the lower bracket 222; please refer to Fig. 9 As shown, the upper bracket 221 and the lower bracket 222 are in a stored state, that is, the length dimension of the second optical component 20 is reduced, thereby reducing the volume of the second optical component 20.

[0112] Optionally, in other embodiments, the upper bracket 221 and the lower bracket 222 are detachably connected. When the user needs the second optical component 20 to perform optical work, the user can connect the upper bracket 221 and the lower bracket 222 to be in an unfolded state along the first direction X, so as to perform the optical work required by the user. When the user does not need the second optical component 20 to perform optical work, the upper bracket 221 and the lower bracket 222 are disassembled to make the upper bracket 221 and the lower bracket 222 in a stored state, that is, the length of the second optical component 20 is reduced, thereby reducing the volume of the second optical component 20.

[0113] Optionally, one of the upper bracket 221 and the lower bracket 222 includes an upper locking portion (not shown in the figure), and the other includes a lower locking portion (not shown in the figure), and the upper locking portion (not shown in the figure) can be locked and connected with the lower locking portion (not shown in the figure). Under this setting, the positions of the upper bracket 221 and the lower bracket 222 can be fixed, so that the position of the image acquisition component 23 disposed on the upper bracket 221 relative to the lower bracket 222 can be fixed, so that the image acquisition component 23 disposed on the upper bracket 221 can reliably complete the optical work required by the user.

[0114] Wherein, either the upper locking part and the lower locking part may be a convex structure, and the other may be a concave structure, and at least a portion of the convex structure may be located in the concave structure, thereby forming a locking connection between the upper locking part and the lower locking part. Alternatively, either the upper locking part and the lower locking part may be a rod structure, and the other may be a hole structure, and at least a portion of the rod structure may be located in the hole structure, thereby forming a locking connection between the upper locking part and the lower locking part. Alternatively, either the upper locking part and the lower locking part may be a plane structure, and the other may be a threaded part, and the threaded part is rotated to increase the static friction between the threaded part and the plane, thereby forming a locking connection between the upper locking part and the lower locking part.

[0115] Furthermore, the second optical unit 20 includes at least one image acquisition component 23, which is the same as the above-mentioned image acquisition component 13 and is not described again. In addition, the embodiment of the present application does not limit the number of image acquisition components 23, and the user can set a corresponding number of image acquisition components 23 according to actual work needs.

[0116] In addition, the optical axis of the image acquisition component 23 provided on the upper bracket 221 may be perpendicular to the first direction X or may have an acute angle or an obtuse angle with the first direction X. Accordingly, the image acquisition component 23 provided on the upper bracket 221 may be rotatably connected to the upper bracket 221, so that the user can adjust the direction of the optical axis of the image acquisition component 23 provided on the upper bracket 221. Of course, the optical axis of the image acquisition component 23 provided on the lower bracket 222 may be perpendicular to the first direction X or may have an acute angle or an obtuse angle with the first direction X. Accordingly, the image acquisition component 23 provided on the lower bracket 222 may also be rotatably connected to the lower bracket 222, so that the user can adjust the direction of the optical axis of the image acquisition component 23 provided on the lower bracket 222.

[0117] Furthermore, the image acquisition component 23 disposed on the upper bracket 221 can be slidably connected to the upper bracket 221, so that the user can adjust the relative position of the image acquisition component 23 disposed on the upper bracket 221 and the upper bracket 221. Of course, the image acquisition component 23 disposed on the lower bracket 222 can be slidably connected to the lower bracket 222, so that the user can adjust the relative position of the image acquisition component 23 disposed on the lower bracket 222 and the lower bracket 222.

[0118] Optionally, the upper bracket 221 is provided with at least two image acquisition components 23 spaced apart along the first direction X. Under this arrangement, the optical working range of the second optical component 20 is relatively large.

[0119] Optionally, the lower support 222 is also provided with at least two image acquisition components 23 spaced apart along the first direction X. Under this arrangement, the optical working range of the second optical component 20 is also relatively large.

[0120] The following content of this article is mainly described by taking the example that the upper bracket 221 and the lower bracket 222 are both provided with at least two image acquisition components 23 spaced apart along the first direction X. Under this setting, if the image acquisition component 23 is a camera, and if the work that the image acquisition component 23 can perform is optical scanning, the optical scanning range of the second optical component 20 of this embodiment is large, so that the human body, artwork or industrial design can be scanned. The embodiment of the present application is not limited to the spacing distance between each two image acquisition components 23.

[0121] When the user needs the second optical component 20 to perform optical work, the user can make the support member 22 unfold along the first direction, so that the second optical unit performs the optical work required by the user. When the user does not need the second optical component 22 to perform optical work, the user can make the support member 22 stored, that is, the length of the second optical component 20 becomes smaller, so that the volume of the second optical component 20 becomes smaller. Under this setting, the second optical component 20 with a smaller volume has a higher degree of maneuverability, which is convenient for the user to carry the second optical component 20, and the second optical component 20 with a smaller volume occupies less space, which is convenient for the user to store, place or store the second optical component 20, and the user has a higher user experience.

[0122] Optionally, see Fig.12 As shown, at least two optical components 10, 20, 30 may include a third optical component 30, the third optical component 30 includes a support rod 32; a third optical unit is connected to the support rod 32, the third optical unit includes an image acquisition component 34 for acquiring head feature data of the scanned object, and the image acquisition component 34 can slide on the support rod 32 along a first direction.

[0123] Among them, the support rod 32 is an independent rod. In other embodiments, the support rod 32 can be composed of multiple rods, which can have detachable, retractable, foldable and other structures. The specific structure can refer to the above-mentioned retractable part 12 or support part 22, which will not be repeated here.

[0124] Furthermore, the third optical unit 30 includes at least one image acquisition component such as an image acquisition component 34. The image acquisition component 34 may be the same as the above-mentioned image acquisition components 13 and 23. The image acquisition component 34 may be an optical instrument such as a depth sensor, a camera, a projector, a light wave transmitter, a light wave receiver or an optical zoom. Furthermore, the image acquisition component 34 for acquiring the head feature data of the scanned object may be a depth sensor, a telephoto camera, etc., so as to better capture the head feature details of the scanned object.

[0125] In addition, the image acquisition component 34 for acquiring head feature data of the scanned object is mounted on the support rod 32 in the horizontal direction so that the optical axis of the image acquisition component 34 is perpendicular to the first direction X. The image acquisition component 34 can be slidably connected to the support rod 32, so that the user can adjust the relative position of the image acquisition component 34 for acquiring head feature data of the scanned object and the support rod 32, so as to better capture the head feature details of the scanned object.

[0126] Furthermore, at least one image acquisition component 33 is also provided above the image acquisition component 34 for acquiring head feature data of the scanned object along the first direction X. The image acquisition component 33 may be the same as the above-mentioned image acquisition components 13, 23, and 34, and will not be described in detail here. The optical axis of the image acquisition component 33 may have an acute angle or an obtuse angle with the first direction X. Accordingly, the image acquisition component 33 may be rotatably connected to the support rod 32, so that the user can adjust the direction of the optical axis set on the image acquisition component 33.

[0127] When the user uses the third optical component 30 to perform optical work, the head feature data of the scanned object can be captured, so that the collected data is more complete, thereby improving the scanning effect.

[0128] Furthermore, the controller may be connected to the optical assembly 10, and / or 20, and / or 30 via a detachable cable (not shown in the figure), or the controller may also control the optical assembly 10, and / or 20, and / or 30 wirelessly. In addition, the controller may be connected to the support platform 40 via a detachable cable (not shown in the figure), or the controller may also control the support platform 40 wirelessly. Optionally, the controller is used to control the rotation of the optical assembly or the support platform 40, and the controller controls the rotation angle of the optical assembly or the support platform 40 to be less than 360°, which may be 0°, 45°, 90°, 135°, 180°, 225°, 270°, etc. The rotation angle of the optical assembly or the support platform 40 is less than 360°, so as to avoid discomfort caused by the scanned object standing on the support platform 40 for a long time, and to avoid the scanned object being unable to stand stably on the support platform 40 for a long time, thereby affecting data collection.

[0130] In other embodiments, please refer to Figure 2-Figure 4 As shown, the three-dimensional scanning device includes: a supporting platform 40, at least two optical components are arranged around the supporting platform 40 at intervals, a controller controls the rotation of the supporting platform 40, and the optical components can be selected from the first optical component 10, the second optical component 20 or the third optical component 30 according to needs.

[0131] The structures of at least two optical components and the structure of the support platform 40 can be independent. Under this setting, it is convenient for users to carry and store the optical components and the support platform 40 separately. Users can also easily change the relative positions between the optical components and the support platform 40 to reduce the size of the three-dimensional scanning device or occupy less space, which is convenient for users to store the three-dimensional scanning device and provides a higher user experience.

[0132] Furthermore, optionally, the three-dimensional scanning device may further include a light source 50, which is used to illuminate the scanned object, to enhance the brightness of the illuminated object and / or to change the color tone of the illuminated object. The controller may be connected to the light source 50 via a detachable cable (not shown in the figure), or the controller may control the light source 50 wirelessly. The controller may control at least one of the illumination intensity and the color tone of the light source 50.

[0133] Among them, the light source 50 can be arranged on the optical component to facilitate the storage of the three-dimensional scanning device; in other embodiments, the structure of the optical component and the structure of the light source 50 can be independent, and the structure of the support platform 40 and the structure of the light source 50 can be independent. Under this setting, it is convenient for users to carry and store the optical component, the support platform 40 and the light source 50 respectively, and users can also easily change the relative positions between the optical component, the support platform 40 and the light source 50 to reduce the size of the three-dimensional scanning device or reduce the space occupied, which is convenient for users to store the three-dimensional scanning device and provides a higher user experience.
