Description

Technical Field

[0001] This invention relates to the field of tracking scanner technology, and more specifically to a stably adjustable tracking 3D scanner. Background Technology

[0002] A 3D scanner is a scientific instrument used to detect and analyze the shape (geometric structure) and appearance data (such as color, surface albedo, etc.) of objects or environments in the real world. The collected data is often used for 3D reconstruction calculations to create digital models of real objects in the virtual world.

[0003] Currently, tracking 3D scanners are typically spherical in shape, and are used by personnel who hold the scanner with their hands to scan objects. However, if the object being scanned is in a small, confined space, errors in operation can cause the 3D scanner to collide or scratch with the surrounding environment. This not only makes it difficult for personnel to adjust and operate the 3D scanner stably, but also affects the accuracy of subsequent image data acquisition due to collisions and scratches. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a stable and adjustable tracking 3D scanner, which can effectively solve the problem that in the existing technology, when people operate the 3D scanner in a narrow environment, it is easy for the scanner to collide and scratch with the surrounding environment, which makes it impossible for people to adjust and operate the 3D scanner stably, and the collision and scratches will affect the accuracy of the image data of the scanned object in the subsequent scanning.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention provides a stable and adjustable tracking 3D scanner, including a scanning device, and further comprising:

[0007] Multiple buffer devices are provided and distributed on the scanning device to form a buffer protection structure on the outside of the scanning device. This buffer device provides cushioning and support to the scanning device when it approaches external objects. Specifically:

[0008] The device scans an object using a handheld scanner. When the buffer device is in a buffer protection state, it presses against the user's hand, forcing the user's hand to remain in close contact with the scanner while it is protecting the scanning device.

[0009] A limiting cleaning device is installed on the scanning device, and the limiting cleaning device is also connected to a buffer device to block dust accumulated in front of the scanning device when the buffer device is in a buffer protection state, so that the scanning device can scan and acquire image data of the object.

[0010] Furthermore, the scanning device includes:

[0011] The ring body has multiple connecting arms mounted on its side, and two scanner bodies are mounted at the joints of the multiple connecting arms. The ring body also has a grip for holding the ring body.

[0012] Furthermore, the buffer device includes:

[0013] A buffer rod is slidably mounted on a connecting arm. A buffer plate is mounted on one end of the buffer rod, and the buffer plate is located at the end of the buffer rod near the handle. A buffer handle is mounted on the other end of the buffer rod.

[0014] A first buffer spring and a second buffer spring are respectively installed between the connecting arm and the buffer plate, and between the connecting arm and the buffer handle.

[0015] Furthermore, the length of the buffer rod extending beyond the connecting arm is greater than that of the scanner body. This ensures that the buffer rod can stably cushion and protect the scanning device.

[0016] Furthermore, during the buffering and protection process, when the buffer rod retracts the buffer handle into the ring body, the buffer handle is in a state close to the grip, so that the buffer handle can be used to press against the person's hand.

[0017] Furthermore, the restricted cleaning device includes:

[0018] An inner limiting plate is disposed on the side of one of the buffer handles. An outer limiting plate is slidably connected to the outer side of the inner limiting plate. The outer limiting plate is movably connected to the connecting arm, and the inner limiting plate is movably connected to the buffer handle via a movable connecting assembly.

[0019] A supporting limiting spring is installed between the outer limiting plate and the inner limiting plate. The movable connecting assembly is connected to the outer limiting plate via a plate body and a fixed shaft at one end of the plate body. The two outer limiting plates have identical structures. The connection between the movable connecting assembly and the buffer handle is similar. Thus, when the buffer handle is compressed, the buffer handle controls the inner limiting plate to slide and retract within the outer limiting plate, thereby improving the stability of the buffer handle's movement. Simultaneously, when the buffer handle is no longer compressed, the supporting limiting spring can use its elastic force to reset the inner limiting plate, facilitating subsequent restriction of the buffer handle.

[0020] Furthermore, an air inlet is provided on the surface of the outer limiting plate, and an air storage chamber is formed between the outer limiting plate and the inner limiting plate to accommodate the air chamber. A main air pipe is connected to one side of the outer limiting plate.

[0021] Furthermore, a secondary air guide pipe is connected to the side of the main air guide pipe, and both the main air guide pipe and the secondary air guide pipe are located on the side of the scanner body.

[0022] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0023] 1. By setting a buffer device outside the scanning device, when the scanning device approaches an obstacle, the buffer device will contact the obstacle in advance, so that the buffer device can buffer and protect the scanning device. This allows the user to operate the scanning device to scan object image data continuously. At the same time, it makes it convenient for the user to adjust the scanning device and perform scanning operations in narrow application environments.

[0024] 2. When the buffer device is in the buffer protection state, it presses against the user's hand, forcing the user's hand to be in close contact with the scanning device during the protection period. This allows the user to hold the scanning device firmly, so that the scanning device can safely and stably acquire object image data even when the buffer device is in the event of a collision.

[0025] 3. A cleaning structure is formed between the buffer device and the limiting cleaning device, so that the limiting cleaning device blows the compressed gas to the front of the scanning device to form an airflow obstruction barrier on the lens in the scanning device. This ensures that even if the obstacle is vibrating or shaking, the dust that accumulates can be blocked and restricted by the airflow obstruction barrier, so that the lens can continuously scan and acquire image data during this process.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] The present invention will be further described below with reference to embodiments.

[0042] Example 1 (see) Figure 1-6 A stably adjustable tracking 3D scanner, including a scanning device 100, and further comprising:

[0043] Multiple buffer devices 200 are provided and distributed on the scanning device 100. They form a buffer protection structure on the outside of the scanning device 100, providing cushioning support when the scanning device 100 approaches an external object. In this solution, the user holds the scanning device 100 to collect and scan image data of an object. Considering the possibility of user error when holding the scanning device 100, which could lead to collisions with other objects, the buffer devices 200 ensure that the user, while holding the scanning device 100, continuously obstructs and protects the external environment of the scanning device 100 during the scanning process. Therefore, when scanning... When the device 100 approaches an obstacle in the environment due to human error, the buffer device 200 makes pre-contact with the obstacle. At this time, the buffer device 200 can collide with the obstacle in place of the scanning device 100, thereby protecting the scanning device 100. At the same time, the buffer device 200 itself is an elastic structure. Therefore, when protecting the scanning device 100, it does so in a buffered movement state. This can greatly reduce the vibration caused by the collision between the buffer device 200 and the obstacle. Since the small vibration will not have a significant impact on the scanning device 100, the user can continuously and uninterruptedly scan the image data of the object to be collected by holding the scanning device 100. At the same time, it is convenient for the user to adjust the scanning device 100 and perform scanning operations in narrow application environments.

[0044] It is worth noting that when the handheld scanning device 100 scans an object, and the buffer device 200 is in a buffer protection state, the buffer device 200 presses against the user's hand, forcing the user's hand to be in close contact with the scanning device 100 during the protection period. Thus, the scanning device 100 can be held firmly by the user's hand, so that the scanning device 100 can safely and stably acquire object image data even when the buffer device 200 is involved in a collision.

[0045] Next, a limiting cleaning device 300 is provided on the scanning device 100, and the limiting cleaning device 300 is also connected to one of the buffer devices 200, so as to block the dust accumulated in front of the scanning device 100 when the buffer device 200 is in the buffer protection state, so that the scanning device 100 can scan and collect image data of the object.

[0046] Referring to the above, the buffer device 200 is used to buffer and protect the scanning device 100 from collisions with obstacles, instead of the scanning device 100. However, it should be considered that during the buffering process, the buffer device 200 cannot guarantee that the obstacle will not vibrate or shake under pressure. Therefore, considering that the obstacle may be shaking, if the shaking causes the dust accumulated on the obstacle to be released, it may affect the scanning device 100 and thus its scanning accuracy. Therefore, when the buffer device 200 is in the buffering protection process, the buffer device 200 controls the connected limiting cleaning device 300 to prevent the limiting cleaning device 300 from colliding with the obstacle. The buffer device 200 can be pre-defined to ensure stable buffer movement. Simultaneously, the buffer movement of the buffer device 200 creates a compressed gas cleaning structure between the buffer device 200 and the limiting cleaning device 300. This allows the limiting cleaning device 300 to blow compressed gas in front of the scanning device 100, forming an airflow obstruction barrier for the lens in the scanning device 100. This prevents dust from being scattered and adhering to the lens surface, ensuring that the lens can continuously scan and acquire image data during this process.

[0047] Specifically, in the above scheme, the scanning device 100 includes:

[0048] The ring body 110 has multiple connecting arms 120 mounted on its side. Two scanner bodies 130 are mounted at the joints of the multiple connecting arms 120. The ring body 110 has a grip bar 140 for holding the ring body 110. Thus, the ring body 110, connecting arms 120, scanner bodies 130 and grip bar 140 constitute a tracking 3D scanner, so that the user can hold the grip bar 140 and the scanner body 130 can accurately collect image datasets of objects in the application environment.

[0049] The buffer device 200 includes:

[0050] A buffer rod 210 is slidably mounted on the connecting arm 120. A buffer plate 211 is installed at one end of the buffer rod 210, and the buffer plate 211 is located at the end of the buffer rod 210 near the handle 140. A buffer handle 212 is installed at the other end of the buffer rod 210.

[0051] A first buffer spring 213 and a second buffer spring 214 are respectively installed between the connecting arm 120 and the buffer plate 211, and between the connecting arm 120 and the buffer handle 212. The first buffer spring 213 and the second buffer spring 214 fix the buffer plate 211 and the buffer handle 212 respectively, so that the buffer rod 210 can move on the connecting arm 120 under the elastic support of the first buffer spring 213 and the second buffer spring 214. Thus, when one end of the buffer handle 212 contacts an obstacle, the buffer rod 210 can retract along the connecting arm 120 to one end, thereby realizing the buffer protection of the scanning device 100 by the buffer rod 210. When the buffer handle 212 leaves the obstacle, the elastic force of the first buffer spring 213 and the second buffer spring 214 can automatically reset, thus making the whole device easy to use later.

[0052] The length of the buffer rod 210 extending out of the connecting arm 120 is greater than that of the scanner body 130; thereby ensuring that the buffer rod 210 can stably buffer and protect the scanning device 100.

[0053] During the buffering and protection process, when the buffer rod 210 retracts the buffer handle 212 into the ring body 110, the buffer handle 212 is in a state close to the grip bar 140, so that the buffer handle 212 can be used to press against the user's hand. Thus, even if the scanning device 100 vibrates or shakes when the scanning device 100 and the buffer device 200 are in the buffering and protection state, the hand can still be firmly gripped on the grip bar 140, which makes it convenient for the user to continuously hold the scanning device 100 to collect object image data. It should be noted that the buffer handle 212 can be made of rubber material to avoid damage to the hand and to prevent damage to the buffer rod 210 controlling the buffer handle 212.

[0054] The limited cleaning device 300 includes:

[0055] An inner limiting plate 310 is disposed on the side of one of the buffer handles 212. An outer limiting plate 320 is slidably connected to the outer side of the inner limiting plate 310. The outer limiting plate 320 is movably connected to the connecting arm 120, and the inner limiting plate 310 is movably connected to the buffer handle 212 via a movable connecting assembly 330.

[0056] A support limiting spring 322 is installed between the outer limiting plate 320 and the inner limiting plate 310. The movable connecting assembly 330 is connected to the outer limiting plate 320 via a plate body and a fixed shaft installed at one end of the plate body. The two outer limiting plates 320 have the same structure. The movable connecting assembly 330 is connected to the buffer handle 212 in the same way. When the buffer handle 212 is compressed, the buffer handle 212 controls the inner limiting plate 310 to slide and retract inside the outer limiting plate 320, thereby improving the stability of the movement of the buffer handle 212. At the same time, when the buffer handle 212 is no longer compressed, the support limiting spring 322 can use elastic force to reset the inner limiting plate 310, which facilitates the subsequent limiting effect on the buffer handle 212.

[0057] An air inlet 321 is provided on the surface of the outer plate 320, and an air storage chamber 323 is formed between the outer plate 320 and the inner plate 310 to accommodate an air chamber. A main air pipe 340 is connected to one side of the outer plate 320.

[0058] The main air duct 340 is connected to the side of the auxiliary air duct 350. Both the main air duct 340 and the auxiliary air duct 350 are located on the side of the scanner body 130.

[0059] Thus, with the inner limiting plate 310 initially positioned inside the outer limiting plate 320, gas can enter and be stored in the gas storage chamber 323 based on the function of the air inlet 321. As the inner limiting plate 310 moves within the outer limiting plate 320, it seals the air inlet 321. The gas flows outward through the main air duct 340 and the secondary air duct 350, forming an airflow obstruction barrier on the side of the scanner body 130. This obstructs the flow direction of dust, preventing dust from falling onto the scanner body 130 and facilitating the scanner body 130 to scan and acquire image data.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
