[0025] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0026] like Figure 1-6 The scanner shown for animal specimen repair or fossil restoration includes a base 1 made of solid material, which is generally made of corrosion-resistant alloy material. Due to its own large gravity, it will have good stability after being placed on the ground. A suspension mechanism 2 is arranged on the base 1 for suspending the object to be scanned. The main part of the base 1 is a bottom plate 101. The side of the bottom plate 101 has an integrated extension plate 102. The bottom surfaces of the bottom plate 101 and the extension plate 102 are fixedly connected with wear-resistant pads 104. The wear-resistant pads 104 are made of rubber material to avoid hard contact between the base 1 and the ground, thereby reducing the probability of hitting the floor tiles. The suspension mechanism 2 includes a height adjustment rod 201 fixedly connected to the upper surface of the extension plate 102. The height adjustment rod 201 actually includes a sleeve fixedly connected to the extension plate 102 and a telescopic rod inserted in the sleeve. A plurality of pin holes are provided, and pins can be inserted into different pin holes to fix the telescopic rod at different heights. The movable end of the height adjustment rod 201 faces upward and is fixedly connected to the cantilever 202. The end of the cantilever 202 away from the height adjustment rod 201 is connected to a suspension rope 203. The suspension rope 203 is generally woven from nylon fibers and has excellent tensile strength, and can easily lift objects weighing more than ten kilograms. Since the suspension rope 203 is made of nylon material, the strength is very high and it can be made very thin, so the structure of the scanned object is hardly affected during the scanning process. The lower end of the suspension rope 203 is connected to a suspension ring 204, which is made of corrosion-resistant alloy material and is used to directly contact the lifted object. The horizontal projection of the suspension rope 203 and the suspension ring 204 is at the geometric center of the base plate 101, so that the lifted object is roughly located in the center of the entire scanning device.

[0027] A rotating mechanism 3 is fixedly connected to the base 1. In order to improve the stability of the rotating mechanism 3, a sink 103 is opened on the upper surface of the bottom plate 101. The specific structure of the rotating mechanism 3 includes a rotating drive 301 fixedly connected to the sink 103. The rotating mechanism 3 includes an electric motor and a planetary reducer. The planetary reducer is driven by the electric motor, which reduces the output speed and increases the output torque, making the rotation process more stable and controllable. The output end of the rotating drive 301, that is, the output end of the planetary reducer, is fixedly connected to a rotating handle 302. The rotation axis of the rotating handle 302 is vertical, and the rotating handle 302 rotates in a horizontal plane.

[0028] The output end of the rotating mechanism 3 is fixedly connected to a horizontal telescopic rod 4, and the movable end of the horizontal telescopic rod 4 is fixedly connected to a vertical telescopic rod 5 via a transfer block 501. The horizontal telescopic rod 4 can change the distance of the vertical telescopic rod 5 relative to the rotation axis of the rotating handle 302, thereby adapting to scanned objects with different cross-sectional sizes. The horizontal telescopic rod 4 adopts an electric telescopic rod with higher control accuracy, which is convenient for the computer to control the telescopic length.

[0029] The movable end of the vertical telescopic rod 5 faces upward and is connected to a swing mechanism 6. The vertical telescopic rod 5 also adopts an electric telescopic rod for accurately controlling the height change of the swing mechanism 6. The swing mechanism 6 has a collection terminal 604 for obtaining surface structure information of the suspended object. In order to ensure the stability of the swing mechanism 6, the movable end of the vertical telescopic rod 5 is fixedly connected to the configuration plate 502. The swing mechanism 6 also includes a servo motor 601 fixedly connected to the configuration plate 502, which has high angle control accuracy and can also be connected to a controller for computer control. The output end of the servo motor 601 is fixedly connected to a transmission shaft 602. The rotation axis of the transmission shaft 602 is horizontal, that is, it is skewed and perpendicular to the rotation axis of the handle 302. The transmission shaft 602 is fixedly connected to the collection terminal 604 through the swing arm 603. The collection terminal 604 can rotate in a vertical plane driven by the transmission shaft 602. Therefore, the collection terminal 604 at the end has two degrees of rotational freedom. The upper surface of the configuration plate 502 has an axis frame 503, and an axis hole 504 is opened on the axis frame 503, which is used to cooperate with the transmission shaft 602 to form a rotating pair. The axis frame 503 is usually also provided with a bearing in the axis hole 504, which cooperates with the transmission shaft 602, thereby improving the rotational stability of the transmission shaft 602.

[0030] Working principle: When in use, first hang the animal specimen or fossil to be scanned on the hanging ring 204. Under the action of gravity, the hanging rope 203 will be stretched and may be twisted, supporting the object to eliminate its rotation or swing. Then, the extension length of the horizontal telescopic rod 4 is set by the computer, so that the horizontal distance between the acquisition terminal 604 and the scanned object is always within an appropriate range. Then, the vertical telescopic rod 5 is started, so that the acquisition terminal 604 is slightly higher than the highest point of the object to be hung, and the acquisition terminal is made to be at a horizontal angle 604 to the object to be hung, thus completing the initialization. When scanning, start the acquisition terminal 6 04 Scan the outer surface of the suspended object. Driven by the servo motor 601, the acquisition terminal 604 swings up and down with the horizontal plane as the symmetry plane. The scanning accuracy is improved by repeatedly acquiring information for comparison and coverage. If the object has a concave structure, it can also be visible under the changing scanning angle. At the same time, the rotating mechanism 3 and the vertical telescopic rod 5 work together to allow the acquisition terminal 604 to gradually descend in a spiral manner until the height of the acquisition terminal 604 is lower than the lowest point of the scanned object. Then a round of scanning is completed. At this time, a highly accurate structural model of animal specimens or fossils will be obtained on the computer.
