Description

Technical Field

[0001] This invention relates to the field of ancient book photography and recording devices, specifically a multi-angle supplementary lighting device for digital photography and recording of ancient books. Background Technology

[0002] Ancient books, as an important carrier and inheritance of Chinese civilization, have extremely high historical, academic and artistic research value. With the increasing emphasis on cultural heritage protection by the state, the regenerative protection of ancient books—that is, to achieve the permanent preservation and widespread dissemination of their contents through high-precision digitization—has become one of the core tasks of libraries, museums and research institutions. In this process, high-quality image acquisition is a key link in digitization work, and the imaging effect directly affects subsequent text recognition, version comparison, virtual restoration and public display. Currently, the digitization of ancient books mainly relies on two types of equipment: non-contact ancient book scanners and shooting platforms based on SLR / medium format cameras. Although these devices meet basic shooting needs to a certain extent, they suffer from uneven lighting and severe shadow interference in practical applications. Most ancient books are bound in the traditional thread-bound, butterfly-bound, or wrapped-back-bound styles, and the pages are naturally curved, making it difficult to lay them flat for shooting. Under the illumination of a single or fixed angle light source, dark shadows are easily generated in the middle of the pages (especially near the spine), resulting in the loss of text information and seriously affecting the integrity and readability of the image. In order to reduce the shadows in the image, some devices force the use of transparent pressure plates to flatten the pages, or rely on operators to manually place acid-free pads for support. Although these methods can improve the image, they can easily cause secondary damage to ancient books that are brittle, infested with insects, or loosely bound. Furthermore, when faced with severely curled or unflattened pages of ancient books, a single vertical perspective cannot fully capture all the text information on the pages. Existing systems generally lack multi-angle collaborative shooting mechanisms, making it difficult to supplement content through image fusion or 3D reconstruction technology, which is extremely inconvenient to use for recording. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-angle supplementary lighting digital photography and recording device for ancient books, so as to solve the problem mentioned in the background art that the imaging effect is poor due to the single and fixed light source and shooting direction when photographing ancient books.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a multi-angle supplementary lighting device for digitally photographing and recording ancient books, comprising a mounting plate, a pole frame fixedly mounted on the outer surface of the mounting plate, the pole frame being a frame design, a control box fixedly mounted on one side of the mounting plate, the control box panel being inclined, sliding frames slidably mounted on the outer surfaces of both sides of the pole frame, an adjustment and fixing mechanism provided between the sliding frames and the pole frame, the adjustment and fixing mechanism comprising: a strong magnet, the strong magnet being embedded in the interior of the sliding frame, and an outer rotating shell rotatably mounted on the outer surface of the sliding frame, a threaded handle threadedly mounted on the side of the outer rotating shell away from the mounting plate, one end of the threaded handle being in contact with the outer surface of the sliding frame, the sliding frame engaging with the pole frame, and a soft light supplementary light fixedly mounted on the side of the outer rotating shell away from the threaded handle, the soft light supplementary light being inclined.

[0005] Preferably, a Y-axis guide rail is fixedly installed on one side of the upright frame, and an X-axis guide rail is fixedly installed on the outer surface of the moving end of the Y-axis guide rail. The X-axis guide rail is slidably connected to the upright frame on one side. A connecting plate is fixedly installed on the outer surface of the moving end of the X-axis guide rail, and the connecting plate is designed to be inclined. A rotation adjustment mechanism is provided on one side of the connecting plate.

[0006] Using the above technical solution, the Y-axis guide rail and X-axis guide rail can be controlled by the control box, allowing the Y-axis guide rail and X-axis guide rail to move along a specific trajectory, carrying the high-definition camera lens to take pictures of the ancient books placed below from multiple positions, so as to obtain pictures from different positions, which is convenient for comparison and restoration of multiple sets of images in later stages.

[0007] Preferably, the rotation adjustment mechanism includes: a drive motor, which is fixedly mounted on the outer surface of the connecting plate, and an adapter shaft is rotatably mounted inside the connecting plate. A high-definition camera lens is rotatably mounted on the outer surface of the adapter shaft, and a hand-tightening nut is threaded onto the outer surface of the high-definition camera lens. The outer surface of the hand-tightening nut is in contact with the outer surface of the adapter shaft. The outer surface of the output end of the drive motor and the outer surface of the adapter shaft are respectively provided with teeth, and the adapter shaft and the drive motor mesh with each other.

[0008] Using the above technical solution, the front-to-back orientation angle of the high-definition camera lens on the connecting plate can be adjusted by tightening the nut by hand. At the same time, the slow rotation of the drive motor and the engagement of the connecting plate allow the left-to-right angle of the connecting plate to be adjusted. This allows the high-definition camera lens to adjust its position during the lateral movement to better photograph and capture images of the ancient books placed below.

[0009] Preferably, a base plate is provided below the mounting plate, and the outer surface of the base plate is in contact with the outer surface of the control box. A guide rod is fixedly installed on the outer surface of the mounting plate near the base plate, and the guide rod is slidably connected to the base plate, and the base plate is engaged with the guide rod.

[0010] By adopting the above technical solution, the engagement of the guide rod and the base plate can effectively limit and fix the position and distance of the upward movement of the mounting plate, so that the mounting plate will not move excessively and cause the guide rod to detach from the base plate. This improves the stability and safety of the mounting plate during movement and shooting. At the same time, the shooting device can be set to a comfortable operating height when facing different users or different placement surfaces, improving the convenience of use while ensuring stability and safety.

[0011] Preferably, a jack is fixedly installed between the base plate and the mounting plate, and a sliding rod is slidably installed on one side of the jack, with both ends of the sliding rod engaging with the outer surface of the jack. The sliding rod is located on the outer side of the mounting plate and the base plate.

[0012] By adopting the above technical solution, the sliding design of the slide rod allows the user to better turn the jack, so as to push the jack to move and displace the mounting plate along the direction of the guide rod. The manual cranking of the jack reduces the vibration of the mounting plate and reduces the vibration caused by excessively fast and violent electric movement. This allows the mounting plate to be adjusted slowly, reducing the chance of ancient books being displaced and damaged due to vibration and other reasons.

[0013] Preferably, guide rail sliders are fixedly installed on the side of the mounting plate away from the base plate, and a support plate is fixedly installed on the outer surface of the moving end of the guide rail slider. A foam pad is fixedly attached to the outer surface of the support plate, and a flexible connection mechanism is provided between the support plate and another support plate.

[0014] By adopting the above technical solution, the added foam pad can support the ancient book and increase the buffer and friction between the ancient book and the support plate, reducing the chance of damage to the ancient book due to displacement caused by force.

[0015] Preferably, the flexible connection mechanism includes: clamping plates, which are respectively attached to both sides of the support plate, and a skin is placed between the support plate and the clamping plates. Another foam pad is attached and fixed to the outer surface of the skin, and the clamping plates and the support plate are fixed with screws.

[0016] Using the above technical solution, the cover can be fixed and replaced by the clamps. At the same time, the soft cover and foam pads can support the spine of the ancient book, reducing the chance of damage caused by the ancient book being placed directly on a flat surface. In addition, the flexible nature of the cover allows the two support plates to move along the direction of the guide rail slider and fit together, which makes it convenient to place individual scrolls or individual fallen pages, ensuring that the pages are flat and do not sink, affecting the clarity of the image. This greatly improves the flexibility of use and the protection of the ancient book.

[0017] Preferably, a threaded rod is rotatably mounted on the side of the mounting plate near the support plate, and the thread directions at both ends of the threaded rod are different. The threaded rod is threadedly connected to the support plate. A hand-tightening handle is fixedly mounted on the side of the threaded rod near the slide rod, and the hand-tightening handle is located on the outside of the mounting plate and the support plate.

[0018] Using the above technical solution, the threaded rod is a trapezoidal screw rod, which can be rotated by manually turning the handle, allowing the support plate to move closer or wider along the direction of the guide rail slider. Combined with the soft properties of the cover, different ancient books can be placed on the foam pad on the surface of the support plate. The distance between the support plates can be flexibly adjusted according to the binding type of the ancient book and the changes during the page turning process, allowing the cover to be relaxed or tightened. This helps to lift or lower the part of the ancient book near the spine, allowing the curved part in the middle of the ancient book to be better captured by the high-definition camera lens, without forcibly flattening or pressing the ancient book. This reduces the probability of damage to the ancient book due to external force and achieves better shooting results.

[0019] Preferably, the support plate has sliding grooves on both sides, and a sliding rod block is slidably installed on the outer surface of the sliding groove, and the sliding rod block is engaged with the sliding groove. A hand screw is threaded on one side of the sliding rod block, and one end of the hand screw is in contact with the outer surface of the sliding groove. A sleeve is rotatably installed on the outer surface of one end of the sliding rod block, and an extension rod is slidably installed inside the sleeve. Insertion holes are evenly opened on the outer surface of the extension rod. A spring pin is slidably installed on one side of the sleeve, and the spring pin is engaged with the insertion hole.

[0020] By employing the above technical solution, the position of the sliding block on the support plate can be flexibly adjusted by hand-tightening the screws and the sliding block. In conjunction with the engagement of the spring pin and the insertion hole, the extension distance of the extension rod can be flexibly adjusted. This allows the four corners of ancient books of different sizes to be pressed and fixed when placed on the shooting and recording device, reducing displacement caused by page movement and flipping during the shooting process. At the same time, it ensures that the ancient book will not move due to the tension or slack of the cover when the support plate is moved and the spacing is adjusted, allowing the high-definition shooting lens to obtain better imaging results, while ensuring the universality of shooting different ancient books.

[0021] Preferably, an elastic head is fixedly installed at one end of the extension rod outside the sleeve, and the elastic head is cylindrical. An adjusting rod is fixedly installed on the side of the slide block away from the support plate, and a plug sleeve is slidably installed on the outer surface of the adjusting rod. A spring plate is fixedly installed on the outer surface of the plug sleeve, and the outer surface of the spring plate is in contact with the outer surface of one end of the sleeve, and the sleeve and the spring plate are engaged. A fixing screw is threadedly installed at the end of the plug sleeve away from the spring plate, and one end of the fixing screw is in contact with the outer surface of the adjusting rod.

[0022] By adopting the above technical solution, the position of the plug sleeve on the adjusting rod is fixed by tightening the fixing screw, so that the position of the spring plate can be flexibly adjusted. This allows the spring plate to squeeze and push the sleeve with different forces, enabling the sleeve and extension rod to flexibly adjust the clamping force on the four corners of the ancient book pages, and to flexibly adjust the clamping force when clamping ancient books of different materials. In conjunction with the use of the elastic head, the probability of ancient books being damaged by clamping is reduced.

[0023] Compared with the prior art, the beneficial effects of the present invention are: a multi-angle supplementary lighting device for digitally photographing and recording ancient books. 1. When using, simply place the ancient book on the support plate, then adjust the position of the sliding frame on the stand according to the size of the ancient book being photographed. Fix the sliding frame with strong magnets, then loosen the threaded handle and rotate the outer shell to adjust the soft light to the most suitable position. Then lock it with the threaded handle and flexibly adjust the position and direction of the soft light so that the multiple soft light on both sides of the stand can illuminate the ancient book from multiple directions, so as to reduce the shadows caused by the light on the pages of the ancient book and allow the high-definition shooting lens to obtain better shooting image effect; 2. During use, the movement distance and trajectory of the Y-axis and X-axis guide rails can be set through the control box. In conjunction with the drive motor, the connecting plate rotates at a slight angle, allowing the high-definition camera lens to move to a specific position and stop to photograph the ancient book below. By moving the high-definition camera lens to multiple shooting points to photograph multiple positions of the ancient book, more images from different directions and positions can be obtained. This facilitates the later comparison and stitching of multiple images for restoration, further improving the image quality and the post-restoration effect. 3. The jack can be opened by rotating the sliding rod, so that the height between the mounting plate and the base plate can be adjusted. The mounting plate can move vertically along the direction of the guide rod, so that the support plate can be adjusted to a suitable height when different users or when the shooting device is placed on a platform of different heights. This makes the posture of the shooting personnel more comfortable and convenient when flipping and placing ancient books, greatly reducing the physical discomfort of the shooting personnel during long shooting and adjustment processes, and improving the comfort of using and operating the shooting device. 4. By turning the hand crank to rotate the threaded rod, the distance between the support plates is adjusted, allowing the support plates to move vertically along the direction of the guide rail slider. In conjunction with the use of the skin and foam pad, the spine of the ancient book is positioned inside the skin. The displacement of the support plates adjusts the tightness of the skin after the ancient book is placed on it, allowing the ancient book to open naturally without the need for squeezing or pressing. This greatly reduces the chance of damage to the ancient book and also achieves better imaging results. 5. The sliding block can be flexibly fixed at any position on the slide groove by hand-tightening the screws. With the spring pin inserted into the insertion hole, the length of the sleeve and extension rod can be flexibly adjusted. Then, by adjusting the position of the insertion sleeve on the adjustment rod, the elastic force applied by the spring plate to the sleeve can be flexibly adjusted. When facing ancient books of different sizes and thicknesses placed on the support plate, the four corners of the opened pages of the ancient book can be pressed and fixed. With the use of the elastic head and foam pad, the chance of damage to the ancient book is further reduced, and better image shooting effect can be obtained. At the same time, the versatility of shooting and fixing the position of ancient books of different sizes is improved. Attached Figure Description

[0026] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-10 This invention provides a technical solution: a multi-angle supplementary lighting digitization recording device for ancient books includes a mounting plate 1, a pole frame 3 fixedly mounted on the outer surface of the mounting plate 1, and the pole frame 3 is a frame design. A control box 2 is fixedly mounted on one side of the mounting plate 1, and the panel of the control box 2 is inclined. Sliding frames 4 are slidably mounted on the outer surfaces of both sides of the pole frame 3. An adjustment and fixing mechanism is provided between the sliding frames 4 and the pole frame 3. The adjustment and fixing mechanism includes a strong magnet 5, which is embedded in the interior of the sliding frames 4. An outer rotating shell 6 is rotatably mounted on the outer surface of the sliding frames 4. A threaded handle 7 is threadedly mounted on the side of the outer rotating shell 6 away from the mounting plate 1, and one end of the outer surface of the threaded handle 7 is in contact with the outer surface of the sliding frames 4. The sliding frames 4 and the pole frame 3 are engaged. A soft light supplementary light 8 is fixedly mounted on the side of the outer rotating shell 6 away from the threaded handle 7, and the soft light supplementary light 8 is inclined.

[0028] Firstly, the soft light supplement lamp 8 is a multi-color lamp. When supplementing light on ancient books, simply push the sliding frame 4 according to the size of the ancient book, push the sliding frame 4 to a suitable position on the upright frame 3, and rotate the outer shell 6 to drive the soft light supplement lamp 8 to rotate. Observe the light of the soft light supplement lamp 8 shining on the ancient book and adjust it to the best lighting position. Then, tighten the threaded handle 7 to fix the position of the soft light supplement lamp 8. The sliding frame 4 is fixed to the upright frame 3 by the attraction of the strong magnet 5, so that the multiple soft light supplement lamps 8 on both sides of the upright frame 3 can flexibly adjust the position and direction of the light to supplement light on the ancient book and eliminate shadows on the pages of the ancient book. The light color of the soft light supplement lamp 8 can also be adjusted according to the material of the ancient book, so that the high-definition shooting lens 14 can get better image effect when shooting, and greatly improve the image shooting effect of the shooting recording device.

[0029] A Y-axis guide rail 9 is fixedly installed on one side of the upright frame 3, and an X-axis guide rail 10 is fixedly installed on the outer surface of the moving end of the Y-axis guide rail 9. The X-axis guide rail 10 is slidably connected to the upright frame 3 on one side. A connecting plate 11 is fixedly installed on the outer surface of the moving end of the X-axis guide rail 10. The connecting plate 11 is designed to be inclined. A rotation adjustment mechanism is provided on one side of the connecting plate 11. The rotation adjustment mechanism includes a drive motor 12, which is fixedly installed on the outer surface of the connecting plate 11. A transition shaft 13 is rotatably installed inside the connecting plate 11. A high-definition camera lens 14 is rotatably installed on the outer surface of the transition shaft 13. A hand-tightening nut 15 is threaded on the outer surface of the high-definition camera lens 14. The outer surface of the hand-tightening nut 15 is in contact with the outer surface of the transition shaft 13. The outer surface of the output end of the drive motor 12 and the outer surface of the transition shaft 13 are respectively provided with teeth, and the transition shaft 13 and the drive motor 12 mesh with each other.

[0030] Secondly, during use, the movement direction and trajectory of the Y-axis guide rail 9 and X-axis guide rail 10 can be controlled by the control box 2, allowing the high-definition shooting lens 14 to move stably to different positions above the ancient book, stop, and take pictures. At the same time, the drive motor 12 can drive the adapter shaft 13 to rotate on the connecting plate 11, allowing the high-definition shooting lens 14 to slowly rotate and adjust the shooting angle. The high-definition shooting lens 14 can be tilted to take pictures at different positions on the ancient book to obtain images of the ancient book content from different positions and angles. When facing some pictures with poor shapes or images, the forward or backward tilt angle of the high-definition shooting lens 14 can be adjusted by hand-tightening the nut 15, so that the high-definition shooting lens 14 can better capture the ancient book, rather than just recording a single page of the ancient book. This allows for comparison, stitching, and restoration of images from multiple angles during subsequent image processing, further improving the practicality of the ancient book shooting and recording device.

[0031] A base plate 16 is provided below the mounting plate 1, and the outer surface of the base plate 16 is in contact with the outer surface of the control box 2. A guide rod 17 is fixedly installed on the outer surface of the mounting plate 1 near the base plate 16, and the guide rod 17 is slidably connected to the base plate 16. The base plate 16 and the guide rod 17 are engaged. A jack 18 is fixedly installed between the base plate 16 and the mounting plate 1, and a sliding rod 19 is slidably installed on one side of the jack 18. The two ends of the sliding rod 19 are engaged with the outer surface of the jack 18, and the sliding rod 19 is located on the outside of the mounting plate 1 and the base plate 16.

[0032] Furthermore, when the recording device is moved to different locations or positions for use, or when it is used by users of different heights, simply rotate the slide bar 19 to adjust the opening and closing of the jack 18, thereby adjusting the distance between the mounting plate 1 and the base plate 16. This allows the mounting plate 1 to move along the direction of the guide rod 17, and the support plate 21 to be adjusted to a suitable height for the user. This reduces the discomfort and fatigue caused by posture when the user frequently flips through ancient books and operates the recording device, greatly improving the practicality and comfort of the recording device.

[0033] On the side of the mounting plate 1 away from the base plate 16, guide rail sliders 20 are fixedly installed, and a support plate 21 is fixedly installed on the outer surface of the moving end of the guide rail slider 20. A foam pad 22 is fixedly attached to the outer surface of the support plate 21. A flexible connection mechanism is provided between the support plate 21 and another support plate 21. The flexible connection mechanism includes: a clamping plate 23, which is respectively attached to both sides of the support plate 21. A skin 24 is placed and clamped between the support plate 21 and the clamping plate 23. Another foam pad 22 is fixedly attached to the outer surface of the skin 24. The clamping plate 23 and the support plate 21 are fixed with screws. A threaded rod 25 is rotatably installed on the side of the mounting plate 1 near the support plate 21. The thread directions at both ends of the threaded rod 25 are different. The threaded rod 25 is threadedly connected to the support plate 21. A hand-tightening handle 26 is fixedly installed on the side of the threaded rod 25 near the slide rod 19. The hand-tightening handle 26 is located on the outside of the mounting plate 1 and the support plate 21.

[0034] When placing ancient books, the spine of the book needs to be placed on the cover 24, and the pages placed on one side of the support plate 21. The foam pad 22 is used to support and prevent slipping of the ancient book. Then, the four corners of the ancient book are fixed. Then, by turning the handle 26, the threaded rod 25 is rotated, allowing the support plate 21 to move along the direction of the guide rail slider 20. This allows the support plate 21 to move along with the cover 24. The cover 24 is fixed by the clamp 23, and different lengths of the cover 24 can be replaced to adapt to different sizes. The ancient book's cover 24 can be tensioned and relaxed to support it and prevent it from falling. At the same time, by changing the state of the cover 24, the spine of the ancient book is supported. The middle part of the ancient book can be lifted and opened naturally. Manual operation can reduce the damage caused by excessive lifting of the ancient book, allowing the content in the middle part of the ancient book to be better displayed. With the supplementary lighting of the soft light 8, the high-definition shooting lens 14 can obtain clearer images when shooting, greatly improving the practicality of the shooting and recording device.

[0035] The support plate 21 has sliding grooves 27 on both sides, and a sliding rod block 28 is slidably installed on the outer surface of the sliding groove 27, and the sliding rod block 28 engages with the sliding groove 27. A hand screw 33 is threaded on one side of the sliding rod block 28, and one end of the hand screw 33 is in contact with the outer surface of the sliding groove 27. A sleeve 29 is rotatably installed on the outer surface of one end of the sliding rod block 28, and an extension rod 30 is slidably installed inside the sleeve 29. Insertion holes 35 are evenly opened on the outer surface of the extension rod 30. A spring pin 32 is slidably installed on one side of the sleeve 29, and the spring pin 32 engages with the insertion hole 35. A spring head 31 is fixedly installed at one end of the rod 30 outside the sleeve 29. The spring head 31 is cylindrical. An adjusting rod 34 is fixedly installed on the side of the slide block 28 away from the support plate 21. A plug sleeve 36 is slidably installed on the outer surface of the adjusting rod 34. A spring plate 37 is fixedly installed on the outer surface of the plug sleeve 36. The outer surface of the spring plate 37 is in contact with the outer surface of one end of the sleeve 29. The sleeve 29 and the spring plate 37 are engaged. A fixing screw 38 is threaded on the end of the plug sleeve 36 away from the spring plate 37. One end of the fixing screw 38 is in contact with the outer surface of the adjusting rod 34.

[0036] After the ancient book is placed on the support plate 21, the extension rod 30 can be adjusted from the sleeve 29 according to the size of the ancient book and the distance between it and the slide groove 27. Then, the extension rod 30 is fixed by inserting the spring pin 32 into the insertion hole 35. Next, the position of the slide block 28 on the slide groove 27 is adjusted so that the elastic head 31 can press against the four corners of the ancient book where there are no words. The slide block 28 is then fixed by tightening the screws 33. Finally, the insertion sleeve 36 is inserted according to the thickness of the ancient book. Within the adjusting rod 34, the spring plate 37 can compress the sleeve 29, giving the sleeve 29 an appropriate amount of elasticity. Then, tighten the fixing screw 38 to fix the plug sleeve 36, allowing the sleeve 29 and the extension rod 30 to press the four corners of the ancient book's pages with appropriate elasticity. This prevents the pages of the ancient book from moving randomly during the shooting process and from turning the pages due to the adjustment of the support plate 21. This facilitates the fixing of ancient books of different sizes and further improves the image shooting effect of the shooting recording device.

[0037] Working principle: After placing the device on the table, rotating the slide rod 19 drives the jack 18 to adjust the distance between the mounting plate 1 and the base plate 16, allowing the support plate 21 to be adjusted to a suitable and convenient height for the photographer. Then, select a cover 24 of the corresponding length according to the size of the ancient book, and fix the cover 24 with the clamp 23. Next, place the ancient book on the support plate 21, insert the spine between the cover 24, and then adjust the length of the sleeve 29 and the extension rod 30, and adjust the position of the slide block 28 on the slide groove 27 so that the elastic head 31 can be positioned within the ancient book. The four corners of the page are then aligned, and the insert sleeve 36 is pushed into the adjusting rod 34, allowing the spring plate 37 to compress the sleeve 29, giving the sleeve 29 appropriate elasticity. The adjusting rod 34 is then fixed with the fixing screw 38, securing the sleeve 29 and the extension rod 30 to the four corners of the ancient book's pages. The hand-tightening handle 26 is then turned, causing the threaded rod 25 to rotate, moving the support plate 21 along the guide rail slider 20 and adjusting the distance between the support plates 21. This allows the cover 24 to be gradually stretched and tightened, pushing the spine of the ancient book upwards. Through flexible support and stabilization, the ancient book... The middle part of the book can naturally expand under the support and gravity. Then, adjust the position of the sliding frame 4 on the upright frame 3, and adjust the orientation of the soft light 8 by rotating the outer shell 6. Adjust the angle by observing the shadow produced by the light from the soft light 8 on the ancient book. After adjustment, fix the outer shell 6 with the threaded handle 7. Then, adjust and operate the movement direction and trajectory of the Y-axis guide rail 9 and X-axis guide rail 10 through the control box 2 to move the high-definition shooting lens 14 above the ancient book, and cooperate with the drive motor 12 to drive the adapter shaft. 13. Slightly rotate and adjust the orientation of the high-definition shooting lens 14 so that the high-definition shooting lens 14 can shoot and record the ancient book from different positions and angles above it. After shooting two pages of the ancient book, check the image through the control box 2.
