[0028] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a 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 those of ordinary skill in the art shall fall within the protection scope of the present application.

[0029] Please refer to Figure 1 、 Figure 2 , first, an exemplary introduction to the application scenarios of fiducial points in related technologies will be given. Fiducial points are feature points that facilitate camera recognition and tracking. The camera can capture the feature points in the collected images in real time, such as Figure 1 the circular feature points shown in

[0030] to achieve the motion tracking function. The fiducial points can be markers with a reflective material covering their surfaces, and common shapes are as shown in Figure 1 circular or other shapes. Taking the oral medical scenario as an example, pasting the fiducial points on the teeth can achieve the capture of tooth movement. However, the current method of pasting fiducial points is relatively inefficient.

[0031] Taking Figure 2 as an example, an exemplary introduction to a fiducial point pasting scenario in related technologies will be given below:

[0032] Taking the oral medical scenario as an example, when pasting fiducial points on teeth, first, the saliva on the tooth surface is dried with a triple syringe to keep the tooth surface dry. Then, a light-curing resin is applied to the tooth surface or the fiducial point surface, and the fiducial point is pasted on the tooth surface using the viscosity of the light-curing resin. To ensure that the fiducial point is stable and does not fall off, finally, an ultraviolet curing lamp is used to irradiate the light-curing resin for a certain period of time (e.g., 10 seconds) to cure the light-curing resin, thus completing the pasting process of one fiducial point. Taking the lower jaw as an example, if the fiducial point is pasted on the lower jaw teeth, the movement of the lower jaw can be captured. However, when pasting fiducial points on objects such as teeth, multiple fiducial points are often required to accurately capture the movement. In the related art, in the case of needing to paste multiple fiducial points, the multiple fiducial points are independent of each other, and the fiducial points often need to be pasted one by one, resulting in low operation efficiency.

[0033] It should be noted that the above introduction to the fiducial point pasting scenario taking the oral medical scenario as an example is only an exemplary display. In actual applications, other application scenarios are not excluded, such as facial motion capture, human motion capture, etc. Therefore, the specific fiducial point pasting scenario is not limited.

[0034] To address the above problems, the present application provides a fiducial point paste that can improve operation efficiency.

[0035] As Figure 3A 、 Figure 3B shown, the fiducial point paste can at least include an adsorption layer 101, a fiducial point layer 102, and an adhesive layer 103;

[0036] The fiducial point layer 102 includes multiple fiducial points 1021 (such as the three fiducial points shown in Figure 3A ), and the multiple fiducial points 1021 are adsorbed on the adsorption layer 101. Among them, at least two of the fiducial points 1021 are adsorbed on the same side surface of the adsorption layer 101 (such as Figure 3B shown, the three fiducial points are all adsorbed on the lower side surface of the adsorption layer);

[0037] The adhesive layer 103 includes multiple adhesives 1031, and the multiple adhesives 1031 are respectively fixed on the surfaces of the multiple fiducial points 1021 (such as Figure 3B shown, the adhesive layer includes three adhesives, and the three adhesives are respectively fixed on the surfaces of the three fiducial points). The adhesive 1031 is used to fix the fiducial point 1021 on the external object when pasting with the external object;

[0038] When the fiducial point 1021 is fixed on the external object under the action of the adhesive 1031, the adsorption layer 101 can be separated from the fiducial point 1021 under the action of an external force.

[0039] For example, as Figure 3B shown, the fiducial points adsorbed by the adsorption layer 101 can be two, three, four, five, etc. At least two fiducial points should be adsorbed on the same side surface of the adsorption layer 101, such as three, four, five. Taking Figure 3B as an example, three fiducial points are adsorbed on one side surface of the adsorption layer 101. Therefore, the number of fiducial points adsorbed by the adsorption layer 101 is not specifically limited.

[0040] For example, the external object can be a tooth, a face, a human limb or other object, and there is no specific limitation on this.

[0041] For example, the above external force can refer to human force, such as the force generated by hand tearing, or the driving force of a machine, and there is no specific limitation on this.

[0042] Considering the dental medical scenario, if fiducial points need to be pasted on teeth in the oral cavity, since saliva is continuously generated in the oral cavity, when pasting fiducial points on teeth, due to the influence of saliva, the surface of the teeth is not dry enough, resulting in poor pasting effect. Especially in the related technology, when pasting markers with photocuring resin, when the teeth are not dry enough due to the influence of saliva, the photocuring resin is often prone to fall off. In the related technology, to reduce the influence of saliva, a triple syringe gun is needed to dry the saliva on the tooth surface before pasting the fiducial points. After keeping the tooth surface dry, photocuring resin is applied on the tooth or the back of the fiducial point, and then the fiducial point is pasted on the tooth surface through the photocuring resin, and finally the photocuring resin is irradiated with an ultraviolet light curing lamp to cure it. This process is relatively cumbersome and complex, and requires the assistance of many devices, but the pasting effect is poor and the operation complexity is high.

[0043] To solve this problem, for example, the above viscous substance can be a hydrophilic double-sided adhesive, which can adsorb saliva when encountering saliva during the process of pasting or using the fiducial points, so as to be not affected by saliva, maintain the pasting effect of the viscous substance, and can reduce the influence of saliva without the need to rely on other devices and without the need for curing, thereby reducing the operation complexity.

[0044] For example, the above viscous substance can have biocompatibility, so that in the dental medical scenario, if fiducial points need to be pasted on teeth in the oral cavity, it can ensure that the viscous substance does not affect human health and is non-toxic and harmless when present in the oral cavity.

[0045] It should be noted that the above introduction to the material of the viscous substance is only an exemplary display. In actual applications, other materials are not excluded, and there is no specific limitation on this.

[0046] Please refer to Figure 4, as an example, the above-mentioned fiducial point sticker may further include a separation layer 104 capable of isolating the above-mentioned adhesive from the outside. The separation layer 104 is attached to the adhesive layer 103, and the separation layer 104 can be detached from the adhesive layer 103 under an external force. By providing the separation layer, the adhesive can be isolated from the outside, preventing the adhesive from being contaminated and ensuring the stability of the adhesiveness of the adhesive. At the same time, the separation layer can also be detached from the adhesive layer under an external force, enabling the adhesive to exert its sticking effect.

[0047] As an example, the above-mentioned external force may refer to human force, such as the force generated by tearing with a human hand, or the driving force of a machine, and specific limitations are not made in this regard.

[0048] As an example, the multiple fiducial points 1021 may all be adsorbed on the same side surface of the adsorption layer 101, Figure 3B , Figure 4 for example, the multiple fiducial points may all be adsorbed on the lower side surface of the adsorption layer, which is convenient for pasting.

[0049] It should be noted that the above introduction to the arrangement of the fiducial points on the adsorption layer is only an exemplary display. In actual applications, other arrangement methods are not excluded, and specific limitations are not made in this regard.

[0050] As an example, the fiducial point sticker may be applied to the oral diagnosis and treatment scenario, and the fiducial point sticker is used to paste fiducial points on the upper teeth and / or lower teeth. When it is necessary to perform motion capture on the upper teeth or lower teeth, facial scanning is often required, and the motion capture process is realized by means of the pasted fiducial points.

[0051] As an example, the adsorption force of the above-mentioned adsorption layer 101 may be the adsorption force of adhesive adsorption or the adsorption force of electrostatic adsorption, and specific limitations are not made in this regard.

[0052] As an example, the above-mentioned adsorption layer 101 may be a plastic-sealed film or other materials with adsorption force, and specific limitations are not made in this regard.

[0053] As an example, the above-mentioned fiducial points 1021 may be reflective fiducial points to improve the recognition effect of the fiducial points, or the above-mentioned fiducial points 1021 may also be non-reflective fiducial points, and specific limitations are not made in this regard.

[0054] As an example, the shape of the above-mentioned fiducial points 1021 may be circular, as shown in Figure 3A , or other shapes, such as rectangular, triangular, etc., and specific limitations are not made in this regard.

[0055] As an example, the above-mentioned separation layer 104 may be release paper (also known as silicone paper or anti-sticking paper), or other materials that can play a role in isolating sticky substances, and specific limitations are not made in this regard.

[0056] In the technical solution provided by the embodiment of the present application, multiple fiducial points are adsorbed on the same adsorption layer, so that the same side surface of the adsorption layer contains multiple fiducial points. When pasting the fiducial points, the multiple fiducial points attached to the same side surface of the adsorption layer can be integrally pasted onto an external object through the adhesive on the surface of the fiducial points, thereby improving the operation efficiency.

[0057] Corresponding to the fiducial point sticker described in any of the above embodiments, an embodiment of the present application further provides a method for manufacturing a fiducial point sticker for manufacturing the fiducial point sticker described in any of the above embodiments, as Figure 5 shown, the method includes the following steps:

[0058] S501. Adsorb multiple fiducial points through the adsorption layer, wherein at least two of the fiducial points are adsorbed on the same side surface of the adsorption layer;

[0059] S502. Fix adhesives on the surfaces of the multiple fiducial points respectively to paste the multiple fiducial points onto an external object through the adhesives; when the fiducial point 1021 is fixed on the external object under the action of the adhesive 1031, the adsorption layer 101 can be separated from the fiducial point 1021 under the action of an external force.

[0060] As an example, a separation layer is provided on the surface of the adhesive to isolate the adhesive from the outside, and the separation layer can be separated from the adhesive under the action of an external force.

[0061] As an example, the adhesive is a hydrophilic double-sided tape.

[0062] As an example, the adhesive has biocompatibility.

[0063] As an example, all of the multiple fiducial points are adsorbed on the same side surface of the adsorption layer.

[0064] As an example, the multiple fiducial points are adsorbed on both side surfaces of the adsorption layer, and at least two of the fiducial points are adsorbed on each of the two side surfaces of the adsorption layer.

[0065] As an example, the number of the fiducial points adsorbed on the two side surfaces of the adsorption layer is the same, and the fiducial points adsorbed on the two side surfaces of the adsorption layer are symmetrically arranged.

[0066] As an example, the fiducial points adsorbed on the two side surfaces of the adsorption layer are asymmetrically arranged.

[0067] The above are only specific embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
