Description

Technical Field

[0001] The present application relates to the technical field of three-dimensional scanning, and in particular to a tracking scanning device. Background Art

[0002] A tracking and scanning device is a device that can dynamically capture the position or motion trajectory of an object and scan and record it. It is mainly suitable for scenes that require continuous monitoring or dynamic data collection. The tracking and scanning device usually includes a skeleton and a marker body. The marker body is equipped with marker points. The marker points are scanned by a visual tracking system to obtain the position and posture of the object to be measured.

[0003] When the marking point is bumped or damaged and needs to be replaced, or when different types of marking points are assembled on the skeleton, the marking body needs to be disassembled to replace the marking point. If the skeleton and the marking body are fixedly connected by dispensing or other methods, the marking body will be difficult to disassemble, and the marking point or skeleton will be easily damaged during the disassembly of the marking body, thereby reducing the service life of the tracking and scanning device. Moreover, even after the marking body is replaced, the relative position of the marking body before and after the replacement on the tracking and scanning device will shift, resulting in the position of the marking point before and after the replacement shifting, thereby reducing the measurement accuracy of the tracking and scanning device.

[0004] Therefore, how to improve the convenience of disassembly and assembly of the marking body and the measurement accuracy of the tracking scanning device is a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0009] Furthermore, the mounting groove is a circular groove structure, and the surfaces where the mounting portion fits with the inner wall of the mounting groove are both curved surfaces, and the curvature radius of the curved surface is consistent with the curvature radius of the mounting groove.

[0010] Furthermore, a section plane perpendicular to the axial direction of the installation groove is defined, and the shape of the cross section of the installation portion cut by the section plane is a "X" shape, a "I" shape, a "human" shape or a "T" shape.

[0011] Furthermore, the tracking and scanning device includes a clamping member and a fixing member.

[0013] Furthermore, the clamping member is provided with a second through hole which passes through the clamping member along the axial direction of the mounting groove, defining a cross-sectional plane perpendicular to the axial direction of the mounting groove, and the cross-section of the mounting portion cut by the cross-sectional plane is consistent with the cross-section of the second through hole cut by the cross-sectional plane, so that the mounting portion can be passed through the second through hole and be located in the mounting groove; the clamping member can rotate relative to the mounting portion, so that the second through hole and the mounting portion do not at least partially overlap along the axial direction of the mounting groove.

[0026] like Figure 1 and Figure 2 As shown, the present application provides a tracking and scanning device 100, which is applied to a tracking three-dimensional scanning system. The tracking three-dimensional scanning system includes a tracking device (not shown in the figure) and a tracking and scanning device 100. The tracking and scanning device 100 includes a device body 11 and a marking component 12. The device body 11 includes a skeleton and a scanning component mounted on the skeleton (not shown in the figure). The tracking and scanning device 100 obtains the surface three-dimensional data of the object to be measured through the scanning component. The tracking device obtains the spatial posture of the tracking and scanning device 100 in the process of performing the scanning task by identifying the marking component 12 of the tracking and scanning device 100, and unifies the surface three-dimensional data of the object to be measured obtained by the tracking and scanning device 100 at different positions into the same coordinate system.

[0027] In this embodiment, the marking assembly 12 includes a base 121, a marking body 122, a first magnetic member 123, and a second magnetic member 124. The base 121 is fixedly connected to the device body 11, a marking point is provided on the marking body 122, and the marking body 122 can be detachably connected to the base 121 to achieve a detachable connection between the marking point and the base 121, thereby achieving a detachable connection between the marking point and the device body 11 through the base 121. The provision of the first magnetic member 123 and the second magnetic member 124 enables the marking body 122 to be stably magnetically attracted to the base 121 during installation to the base 121, and is not easy to move or fall out of the base 121, so that the operator can fasten the marking body 122, thereby achieving the convenience of quick disassembly and assembly of the marking body 122 and the device body 11. In some embodiments, the base 121 is fixed to the device body 11 by welding or bolts, and the tag body 122 is detachably connected to the base 121 to achieve a detachable connection between the tag body 122 and the device body 11, thereby facilitating the disassembly and replacement of the tag body 122.

[0028] Specifically, the base 121 is formed with a first positioning portion 1211 and a first fixing groove 1212, and the tag body 122 is formed with a second positioning portion 1221 and a second fixing groove 1222. Among them, the first magnetic member 123 is installed in the first fixing groove 1212, and the second magnetic member 124 is installed in the second fixing groove 1222. More specifically, when the tag body 122 is connected to the base 121, the first positioning portion 1211 and the second positioning portion 1221 cooperate to position, and the first magnetic member 123 and the second magnetic member 124 are magnetically connected. In this way, the base 121 and the tag body 122 can be quickly connected through the first magnetic member 123 and the second magnetic member 124, and the magnetic connection method is also conducive to reducing the difficulty of disassembling the tag body 122 and the base 121, so as to facilitate the rapid disassembly and assembly of the tag body 122 and the base 121, and then to achieve the rapid disassembly and assembly of the tag body 122 and the device body 11, and then to improve the convenience of disassembly and assembly of the tag body 122. Secondly, by improving the convenience of disassembly and assembly of the tag body 122 , it is possible to avoid damage to the tracking and scanning device 100 due to difficulty in disassembly and assembly of the tag body 122 , which is beneficial to increasing the service life of the tracking and scanning device 100 .

[0029] Secondly, during the connection process between the mark body 122 and the base 121, the first positioning portion 1211 and the second positioning portion 1221 can limit the relative position of the mark body 122 and the base 121. When assembling the mark body 122, the mark body 122 and the base 121 can be positioned without manually adjusting the installation position of the mark body 122 and the base 121, and the connection between the mark body 122 and the base 121 is achieved through the first magnetic part 123 and the second magnetic part 124, so as to further improve the convenience of disassembly and assembly of the mark body 122.

[0030] In addition, when replacing the marking body 122, the marking body 122 is limited by the first positioning portion 1211 and the second positioning portion 1221 so that the relative position of the marking point on the marking body 122 and the device body 11 before and after replacement remains unchanged, which is beneficial to improving the measurement accuracy of the tracking and scanning device.

[0031] For example, the first positioning portion 1211 may be a positioning column, and the second positioning portion 1221 may be a positioning hole. During the connection process between the tag body 122 and the base 121 , the positioning hole is inserted into the positioning column to fix the relative position of the tag body 122 and the base 121 .

[0032] It should be noted that, in the present application, the first positioning portion 1211 may be a positioning hole, and the second positioning portion 1221 may be a positioning column. That is, the present application does not limit the structural form of the first positioning portion 1211 and the second positioning portion 1221, and only needs to satisfy that the relative position of the marking body 122 and the base 121 can be limited by the first positioning portion 1211 and the second positioning portion 1221.

[0033] In this embodiment, the first positioning portion 1211 and the first fixing groove 1212 have a preset first relative position, and the second positioning portion 1221 and the second fixing groove 1222 have a preset second relative position. The second relative position is consistent with the first relative position. In this way, it is possible to avoid the misalignment of the base 121 and the tag body 122 due to the inconsistency between the second relative position and the first relative position, so as to facilitate the connection accuracy between the tag body 122 and the base 121.

[0034] As an embodiment, the base 121 is provided with a mounting groove 1213, the first positioning portion 1211 and the first fixing groove 1212 are located at the bottom of the mounting groove 1213, the tag body 122 includes a mounting portion 1223, the second positioning portion 1221 and the second fixing groove 1222 are located on the mounting portion 1223, and when the tag body 122 is connected to the base 121, the mounting portion 1223 is located in the mounting groove 1213. In this way, when the tag body 122 is assembled, the mounting portion 1223 and the mounting groove 1213 can play a role of limiting and guiding the connection between the tag body 122 and the base 121, and at the same time, the mounting portion 1223 and the mounting groove 1213 can also limit the installation space of the first positioning portion 1211 and the second positioning portion 1221, and limit the installation space of the second fixing groove 1222 of the first fixing groove 1212, so as to facilitate the rapid assembly of the tag body 122 and the base 121.

[0035] As an optional implementation, the mounting groove 1213 is a circular groove structure, and the surfaces of the mounting portion 1223 and the inner wall of the mounting groove 1213 are both curved surfaces, and the curvature radius of the curved surface is consistent with the curvature radius of the mounting groove 1213. In this way, the mounting groove 1213 and the mounting portion 1223 can limit the marking body 122 and the base 121 in the radial direction of the mounting groove 1213, and can avoid interfering with the rotation of the marking body 122 relative to the base 121, so that the marking body 122 can be rotated to the position where the first magnetic part 123 is connected to the second magnetic part 124 and the first positioning part 1211 is connected to the second positioning part 1221, thereby improving the convenience of disassembly and assembly between the marking body 122 and the base 121, and further improving the convenience of disassembly and assembly between the marking body 122 and the device body 11.

[0036] In some embodiments, the marking body 122 further includes a connecting portion 1224 and a marking point mounting portion 1225, wherein the connecting portion 1224 is a rod-shaped structure, and the two ends of the connecting portion 1224 are respectively connected to the mounting portion 1223 and the marking point mounting portion 1225. The marking point is located on the marking point mounting portion 1225. It should be noted that the diameter of the connecting portion 1224 is smaller than the diameter of the mounting groove 1213 to avoid the connecting portion 1224 interfering with the assembly of the mounting portion 1223 and the mounting groove 1213, which is conducive to improving the convenience of disassembly and assembly between the marking body 122 and the base 121.

[0037] like Figure 2 and Figure 3As shown, as an embodiment, the tracking scanning device 100 includes a pressing member 13 and a fixing member 14, wherein the pressing member 13 is used to press the mounting portion 1223, and the fixing member 14 is used to press the pressing member 13. Specifically, when the tag body 122 is connected to the base 121, the mounting portion 1223 is located between the pressing member 13 and the bottom of the mounting groove 1213, and the fixing member 14 is connected to the base 121 and abuts against the pressing member 13, so that the pressing member 13 has a pressing force to fit the mounting portion 1223 to the bottom of the mounting groove 1213. In this way, while being connected by the first magnetic member 123 and the second magnetic member 124, the connection stability between the mounting portion 1223 and the base 121 can be further improved by the pressing member 13 and the fixing member 14, thereby improving the connection stability between the tag body 122 and the base 121, and further facilitating the connection stability between the tag body 122 and the device body 11.

[0038] As an embodiment, the fixing member 14 is provided with a first through hole 141 through which the mounting portion 1223 can pass. Specifically, the minimum width of the first through hole 141 along the radial direction of the mounting groove 1213 is greater than the maximum width of the mounting portion 1223 along the radial direction of the mounting groove 1213. In this way, the mounting portion 1223 can pass through the first through hole 141 and enter the interior of the mounting groove 1213, so as to facilitate the disassembly and assembly between the mounting portion 1223 and the base 121.

[0039] More specifically, the minimum width of the pressing member 13 along the radial direction of the mounting groove 1213 is greater than the maximum width of the first through hole 141 along the radial direction of the mounting groove 1213. With such a configuration, when the pressing member 13 presses the mounting portion 1223, it is possible to prevent the pressing member 13 from being separated from the first through hole 141 and causing the pressing member 13 to fail, thereby facilitating the connection stability between the mounting portion 1223 and the base 121, and further facilitating the connection stability between the tag body 122 and the device body 11.

[0040] like Figure 4 and Figure 5As shown, as an embodiment, a cross-sectional plane 101 perpendicular to the axial direction of the mounting groove 1213 is defined, and the shape of the cross section of the mounting portion 1223 cut by the cross-sectional plane 101 is a "cross" shape, a "one" shape, a "human" shape or a "T" shape. Specifically, the clamping member 13 is provided with a second through hole 131 that penetrates the clamping member 13 along the axial direction of the mounting groove 1213, and the cross section of the mounting portion 1223 cut by the cross-sectional plane 101 is consistent with the cross section of the second through hole 131 cut by the cross-sectional plane 101, so that the mounting portion 1223 can be inserted into the second through hole 131 and located in the mounting groove 1213. More specifically, the clamping member 13 can rotate relative to the mounting portion 1223, so that the second through hole 131 and the mounting portion 1223 do not overlap at least partially along the axial direction of the mounting groove 1213. With such arrangement, when disassembling and assembling the marking body 122, the mounting portion 1223 is rotated so that the second through hole 131 and the mounting portion 1223 overlap axially along the mounting groove 1213, so that the mounting portion 1223 can pass through the clamping piece 13, and the mounting portion 1223 can also pass through the fixing piece 14 through the first through hole 141 to achieve separation of the mounting portion 1223 from the base 121. Therefore, when disassembling the marking body 122, it is only necessary to loosen the fixing piece 14 so that the clamping piece 13 no longer has a clamping force on the mounting portion 1223, so that the mounting portion 1223 can be rotated relative to the clamping piece 13, so that the mounting portion 1223 can pass through the second through hole 131 and the first through hole 141 in sequence to be separated from the base 121, and then there is no need to completely disassemble the fixing piece 14 and the clamping piece 13, which is beneficial to improving the convenience of disassembly of the marking body 122. When assembling the marking body 122, the mounting portion 1223 is passed through the first through hole 141 into the interior of the fixing member 14, and then the mounting portion 1223 is rotated so that the mounting portion 1223 and the second through hole 131 overlap axially along the mounting groove 1213, so that the mounting portion 1223 can pass through the second through hole 131 and connect with the mounting groove 1213, and then the pressing member 13 is rotated so that the second through hole 131 and the mounting portion 1223 are misaligned, and then the pressing member 13 is fixed by the fixing member 14 to achieve the pressing of the mounting portion 1223 by the pressing member 13, thereby achieving the assembly of the marking body 122.

[0041] In summary, when the marking body 122 is disassembled and assembled, the marking body 122 can be disassembled and assembled without removing the pressing member 13 and the fixing member 14 from the base 121, thereby further improving the convenience of disassembly and assembly of the marking point.

[0042] It should be noted that the shape of the cross section of the mounting portion 1223 cut by the cutting plane 101 can also be any shape other than a circle, such as a "Y" shape, and the present application does not impose any limitation on this.

[0043] As an embodiment, a first limiting portion 1214 is formed on the base 121, and the first limiting portion 1214 is located on a side of the base 121 close to the marking body 122. A second limiting portion 132 is formed on the clamping member 13, and the second limiting portion 132 is located on a side of the clamping member 13 close to the mounting groove 1213. When the first limiting portion 1214 and the second limiting portion 132 cooperate to limit, the second through hole 131 and the mounting portion 1223 at least partially do not overlap along the axial direction of the mounting groove 1213. In this way, the position of the clamping member 13 can be limited by the first limiting portion 1214 and the second limiting portion 132 to prevent the second through hole 131 on the clamping member 13 from overlapping with the mounting portion 1223 when the marking body 122 is connected to the base 121, thereby preventing the clamping member 13 from failing. This is beneficial to improving the clamping stability of the clamping member 13 on the mounting portion 1223, and further beneficial to improving the connection stability between the mounting portion 1223 and the base 121, and then improving the connection stability between the marking body 122 and the device body 11.

[0044] For example, the first limiting portion 1214 may be a limiting column, and the second limiting portion 132 may be a limiting hole. The cooperation of the limiting hole and the limiting column can improve the connection stability between the pressing member 13 and the base 121, so as to avoid the second through hole 131 on the pressing member 13 overlapping with the mounting portion 1223 when the marking body 122 is connected to the base 121, thereby preventing the pressing member 13 from failing due to the overlap of the second through hole 131 on the pressing member 13 and the mounting portion 1223, thereby facilitating the improvement of the pressing stability of the pressing member 13 on the mounting portion 1223.

[0045] It should be noted that, in the present application, the first limiting portion 1214 may be a limiting hole, and the second limiting portion 132 may be a limiting column. That is, the present application does not limit the structural form of the first limiting portion 1214 and the second limiting portion 132, and it is only required that the relative position of the pressing member 13 and the base 121 can be limited by the first limiting portion 1214 and the second limiting portion 132.

[0046] It should be noted that when the first limiting portion 1214 cooperates with the second limiting portion 132 to limit, and the marking body 122 is connected to the base 121, the mounting portion 1223 and the second through hole 131 do not overlap at least partially along the axial direction of the mounting groove 1213, so as to achieve misalignment of the second through hole 131 and the mounting portion 1223, thereby achieving the clamping of the mounting portion 1223 by the clamping member 13, which is beneficial to improve the connection stability between the mounting portion 1223 and the base 121.

[0047] It should be noted that the mounting portion 1223 includes a fixed state and a disassembled state. When the second through hole 131 and the mounting portion 1223 are misaligned, the mounting portion 1223 cannot be separated from the mounting groove 1213 at the second through hole 131, and at this time, the mounting portion 1223 is in a fixed state. When the second through hole 131 overlaps with the mounting portion 1223, the mounting portion 1223 can pass through the second through hole 131, and at this time, the mounting portion 1223 is in a disassembled state.

[0048] like Figures 2 to 5 As shown, as an embodiment, the fixing member 14 is sleeved on the base 121 and is threadedly connected to the base 121. The fixing member 14 has a locking position and an adjusting position. When the fixing member 14 is in the locking position, the fixing member 14, the pressing member 13, the mounting portion 1223 and the bottom of the mounting groove 1213 are abutted in sequence, and the distance between the first through hole 141 and the bottom of the mounting groove 1213 is a first distance; when the fixing member 14 is in the adjusting position, the distance between the fixing member 14 and the bottom of the mounting groove 1213 is a second distance, and the second distance is greater than the first distance. Among them, the difference between the first distance and the second distance is greater than or equal to the axial length of the second positioning portion 1221 along the mounting groove 1213, so that a disassembly gap can be formed between the fixing member 14 and the mounting groove 1213, which is conducive to moving the mounting portion 1223 to separate the first positioning portion 1211 and the second positioning portion 1221, and is conducive to rotating the mounting portion 1223 to put it in a disassembly state, so that the mounting portion 1223 can pass through the second through hole 131 and the first through hole 141 and be separated from the mounting groove 1213. In this way, when the fixing member 14 is in the adjustment position, the clamping member 13 no longer has a clamping force on the mounting portion 1223, so that the mounting portion 1223 can rotate relative to the clamping member 13, which is conducive to the mounting portion 1223 rotating to a position overlapping with the second through hole 131, and enables the mounting portion 1223 to be able to withdraw from the second through hole 131 and the first through hole 141 in sequence, thereby realizing the disassembly of the mounting portion 1223 and the base 121, and then realizing the disassembly of the marking body 122 and the device body 11. Secondly, when the fixing member 14 is in the adjustment position, the mounting portion 1223 can enter the mounting groove 1213 from the first through hole 141 and the second through hole 131 in sequence, and rotate the mounting portion 1223 so that the first positioning portion 1211 and the second positioning portion 1221 are matched for positioning, and the first magnetic member 123 is magnetically connected to the second magnetic member 124 to achieve the connection between the mounting portion 1223 and the mounting groove 1213. At this time, the second through hole 131 and the mounting portion 1223 are misaligned, and then by rotating the fixing member 14 to the locking position, the pressing member 13 can press the mounting portion 1223, thereby realizing the assembly of the mounting portion 1223 and the base 121, and then realizing the assembly of the marking body 122 and the device body 11.

[0049] It should be noted that when the fixing member 14 is in the locking position, the mounting portion 1223 is in a fixed state to prevent the mounting portion 1223 from being separated from the mounting groove 1213 at the second through hole 131, thereby improving the connection stability between the tag body 122 and the base 121. When the fixing member 14 is in the adjustment position, the mounting portion 1223 is in a disassembly state, so that the mounting portion 1223 can pass through the second through hole 131 and be disassembled and assembled with the base 121.

[0050] As an embodiment, a plurality of receiving grooves 1215 are provided on the base 121, and the plurality of receiving grooves 1215 are arranged around the mounting groove 1213. The tracking scanning device 100 includes a plurality of elastic members 15, each of which is located in one of the receiving grooves 1215, one end of each of the elastic members 15 abuts against the groove bottom of the receiving groove 1215, and the other end of each of the elastic members 15 abuts against the pressing member 13, and each of the elastic members 15 has an acting force on the pressing member 13, and the acting force makes the pressing member 13 have a tendency to move away from the mounting groove 1213. With such an arrangement, when the fixing member 14 is in the adjustment position, the acting force of the elastic member 15 can drive the pressing member 13 away from the mounting portion 1223, so as to facilitate the mounting portion 1223 to move in the mounting groove 1213, thereby facilitating the disassembly and assembly between the marking body 122 and the base 121, and further facilitating the disassembly and assembly between the marking body 122 and the device body 11.

[0051] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to this application.
