[0002] The tracking device is an important component of the tracking type three-dimensional scanner and is used for providing an identification area for the scanning device so that the scanning device can scan a target object located in the identification area.

[0003] At present, when the existing tracking type three-dimensional scanner works on site, the tracking device is usually fixed on a tripod head in a horizontal manner to provide a stable identification area for the scanning device. Since the tracking device provides the identification area for the scanning device by using two camera modules thereon, and the two camera modules are arranged at intervals along the length direction of the tracking device, the identification area provided by the tracking device for the scanning device is rectangular, and when the tracking device is placed horizontally, the height dimension of the identification area is greater than the width dimension, and the height dimension is about 5 meters, which is much higher than the height of an operator holding the scanning device. Therefore, many areas of the identification area provided by the tracking device for the scanning device in the height direction cannot be utilized, thereby reducing the utilization rate of the identification area.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for describing particular embodiments only and is not intended to be limiting of the application. All publications, patent applications, patents, and other references mentioned herein are incorporated by reference in their entirety for the teachings relevant to the sentence and / or paragraph in which the reference is presented.

[0043] As shown in Figures 1 to 3 , Figure 5 The tracking assembly 100 provided by an embodiment of the present application includes a tracking device 10 and a support frame 20. The tracking device 10 includes two camera modules 11. The two camera modules 11 have a height difference in the vertical direction. The two camera modules 11 cooperate with each other and provide an identification area 101 for a scanning device (not shown) so that the scanning device can scan a target object (not shown) located in the identification area 101. The support frame 20 is connected to the tracking device 10 and is used to carry the tracking device 10. Here, the identification area 101 specifically refers to an effective scanning area of the tracking device 10 when the tracking device 10 scans the target object for the scanning device. It is to be noted that the working principle of how the two camera modules 11 on the tracking device 10 cooperate with each other and provide the identification area 101 for the scanning device can adopt a conventional manner, and thus will not be described here.

[0044] It can be understood that, due to the height difference in the vertical direction between the two camera modules 11 on the tracking device 10, the tracking device 10 can increase the area that the identification area 101 provided by the tracking device 10 can cover in the horizontal direction compared with a tracking device that is horizontally placed, thereby improving the utilization of the identification area 101 provided by the tracking device 10 for the scanning device.

[0045] It is to be noted that the tracking device 10 of the present application can increase the area that the identification area 101 provided by the tracking device 10 can cover in the horizontal direction by changing the placement manner when the tracking device 10 is placed on the support frame 20. In this process, the overall identification area 101 of the tracking device 10 does not change, which can facilitate the adjustment and utilization of the identification area 101 provided by the tracking device 10 for the scanning device.

[0046] As shown inFigures 1 to 3 As shown in the figure, in an embodiment, the tracking device 10 is arranged vertically so as to maximize the height difference of the two camera modules 11 in the vertical direction. That is, when the tracking device 10 is arranged vertically on the support frame 20, the tracking device 10 can provide a recognition area 101 that covers an area as large as possible in the horizontal direction, so as to ensure that the tracking device 10 can provide a large enough recognition area 101 for the scanning device. It should be noted that when the target object is arranged on the vertical line of the tracking device 10, the target object is arranged at the middle position of the recognition area 101 provided by the tracking device 10, so as to maximize the use of the recognition area 101 provided by the tracking device 10. Of course, when there is no overlapping part between the recognition area 101 provided by the tracking device 10 and the ground for supporting the target object, the maximum use of the recognition area 101 provided by the tracking device 10 can be achieved.

[0047] As shown in the figure, Figure 5 As shown in the figure, in an embodiment, the installation position of the tracking device 10 on the support frame 20 can be adjusted so as to adjust the height difference of the two camera modules 11 in the vertical direction. That is, the tracking device 10 can adjust the pitch angle of the tracking device 10 when working by adjusting the installation position on the support frame 20, so as to meet the use requirements in different scenes. Here, the center of gravity of the tracking device 10 is arranged at the connection position between the tracking device 10 and the support frame 20, so as to improve the stability of the support frame 20 when carrying the tracking device 10.

[0048] As shown in the figure, Figure 1 , Figures 3 to 6 As shown in the figure, the support frame 20 includes a fixed plate 21, and the tracking device 10 is attached to the fixed plate 21 and is rotationally connected to the fixed plate 21, and the tracking device 10 can rotate on the fixed plate 21 so as to adjust the installation position of the tracking device 10 on the fixed plate 21. That is, the support frame 20 can carry the tracking device 10 by using the fixed plate 21, and adjust the pitch angle of the tracking device 10 when working by driving the tracking device 10 to rotate on the fixed plate 21, so as to facilitate the adjustment of the installation position of the tracking device 10 on the support frame 20.

[0049] As shown in the figure, Figure 4As shown, a first guide hole 211 is provided on the fixed plate 21; a connecting rod 12 is provided on the tracking device 10, and the connecting rod 12 is correspondingly provided with the first guide hole 211. The connecting rod 12 can be inserted and engaged with the corresponding first guide hole 211, and the connecting rod 12 can slide along the first hole wall 2111 of the first guide hole 211 under the drive of the tracking device 10. That is to say, this embodiment can guide the rotation adjustment of the tracking device 10 on the fixed plate 21 by utilizing the insertion and engagement between the connecting rod 12 and the first guide hole 211, thus facilitating the rotation adjustment of the tracking device 10 on the fixed plate 21. Here, the first guide hole 211 can specifically be a through hole or a blind hole, and the shape of the first guide hole 211 can be oblong, rectangular, etc.

[0050] As a preferred option, such as Figure 4 As shown, the number of first guide holes 211 is configured to be multiple, and the multiple first guide holes 211 are independent of each other. This allows for multiple guidance for the rotation adjustment of the tracking device 10 on the fixed plate 21, which further facilitates the rotation adjustment of the tracking device 10 on the fixed plate 21. Here, the number of first guide holes 211 is configured to be two.

[0051] In this embodiment, a locking member (not shown) is detachably connected to the connecting rod 12 at the portion passing through the corresponding first guide hole 211. The locking member connected to the connecting rod 12 can press against the fixing plate 21 to lock the connecting rod 12 onto the fixing plate 21 and fix the tracking device 10 in place. This allows the tracking device 10 to be locked / unlocked on the fixing plate 21 by attaching and removing the locking member from the connecting rod 12, thereby further facilitating the adjustment of the installation position of the tracking device 10 on the support frame 20. Here, the locking member is threaded onto the connecting rod 12, specifically configured as a nut. It is understood that in other embodiments, the locking member is also configured as a pin, which is fitted onto the connecting rod 12 in a plug-in manner.

[0052] like Figure 4 As shown, the tracking device 10 is equipped with a rotating rod 13, which is rotatably connected to the fixed plate 21. In other words, the tracking device 10 can be rotatably connected to the fixed plate 21 via the rotating rod 13.

[0053] like Figure 4As shown, the tracking device 10 is further provided with a swing rod 14, and the fixed plate 21 is provided with a second guide hole 212, which can be inserted with the swing rod 14, and the swing rod 14 can slide along the second hole wall 2121 of the second guide hole 212 under the driving of the tracking device 10, so that the tracking device 10 can be rotatably connected to the fixed plate 21 by the rotating rod 13 and the swing rod 14, thereby improving the stability of the tracking device 10 assembled on the fixed plate 21.

[0054] As shown in Figure 1 , Figures 3 to 6 As shown, the support frame 20 further comprises a connecting plate 22 and at least three support legs 23, the connecting plate 22 is connected with the support legs 23, and the fixed plate 21 is arranged between two adjacent support legs 23 and connected with the connecting plate 22. Here, the number of support legs 23 is three, and the three support legs 23 support the tracking device 10 through the connecting plate 22 and the fixed plate 21, and the stability of supporting the tracking device 10 is improved by the stability of the triangle; in addition, the fixed plate 21 can be fixed to the connecting plate 22 by bolts 201.

[0055] It should be noted that the connecting plate 22 is arc-shaped, and a gap 221 is formed between the two ends of the connecting plate 22, so that when the connecting plate 22 connects the support legs 23 and the fixed plate 21, the gap 221 can be used for the tracking device 10 to enter and exit the connecting plate 22, so that the assembly and connection of the tracking device 10 on the fixed plate 21 of the support frame 20 can be facilitated. It can be understood that in other embodiments, the shape of the connecting plate 22 is not limited to arc-shaped, and those skilled in the art can also set the connecting plate 22 as a special-shaped structure, which will not be described here.

[0056] In addition, the present application also provides a tracking type three-dimensional scanner, which comprises a scanning device and the tracking assembly 100 described above; the tracking device 10 is used for providing an identification area 101 for the scanning device, so that the scanning device can scan a target object located in the identification area 101.

[0057] The technical features of the above embodiments can be combined arbitrarily, and in order to make the description concise, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0058] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not used as a limitation of the present application, and any appropriate changes and variations of the above embodiments within the scope of the present application are within the scope of the present application.
