Description

Technical Field

[0001] This invention relates to the field of cultural relic digitization equipment technology, specifically to an integrated device and method for three-dimensional shape scanning and text extraction of bamboo and wooden slips. Background Technology

[0002] As an important ancient document carrier, the preservation of the three-dimensional shape and the extraction of text from bamboo and wooden slips are crucial aspects of cultural relic protection and historical research. Traditional research on bamboo and wooden slips relies heavily on manual measurement and photographic recording, which is not only inefficient but also prone to causing secondary damage to the artifacts due to contact handling. Existing scanning equipment is mostly designed for single functions, requiring three-dimensional shape scanning and text extraction to be performed step by step. Furthermore, the equipment has poor adjustment flexibility and is difficult to adapt to bamboo and wooden slips of different sizes and shapes. Insufficient lighting or angular deviations during the scanning process can easily lead to blurred text extraction and distorted shape data.

[0003] With the development of cultural relic digitization technology, some bamboo and wooden slip scanning devices have appeared on the market, but they still have obvious defects: a three-dimensional scanning device for cultural relics disclosed in patent number CN202210789012.3, although it has basic scanning functions, lacks targeted supplementary lighting and angle adjustment structures, and the scanning accuracy is limited; moreover, it does not integrate a text extraction module, and data needs to be processed by third-party software in the later stage, which is cumbersome to operate; at the same time, the device is inconvenient to move and fix, and it is difficult to adapt to different usage scenarios such as museums and archaeological sites.

[0004] Existing bamboo and wooden slip scanning and extraction devices generally suffer from the following problems: 1. The scanning and text extraction functions are separated, requiring multiple devices to work together, which is cumbersome and data is easily lost; 2. Insufficient light adjustment makes the text on the surface of the bamboo and wooden slips difficult to identify due to wear and fading, affecting the extraction accuracy; 3. Poor device adjustment flexibility makes it impossible to accurately adapt to the size and placement angle of the bamboo and wooden slips, resulting in incomplete scanning data. The lack of convenient movement and stable fixing structure limits the applicable scenarios and makes it unsuitable for use in field archaeological sites. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated device and method for three-dimensional shape scanning and text extraction of bamboo and wooden slips, so as to solve the problems mentioned in the background art.

[0010] Preferably, the plurality of movable wheels are evenly distributed at the bottom of the insert, and the movable wheels roll in cooperation with the inner wall of the groove, which facilitates the movement of the light panel inside the cavity.

[0011] Preferably, the light panel is an LED fill light panel, and the light panel is slidably connected to the inner cavity. The light panel can be quickly disassembled and its position adjusted by the cooperation of the insert and the slot.

[0012] Preferably, the telescopic rod is an electric telescopic rod, which is distributed along the length of the horizontal plate, and the telescopic rod extends and retracts to drive the connecting block and the horizontal block to move synchronously.

[0013] Preferably, the column can rotate relative to the horizontal plate via a circular bearing, and the plurality of screw holes are evenly distributed along the circumference of the disc. The installation angle of the fixing plate is adjusted by the cooperation of bolts with different screw holes.

[0014] Preferably, the fixing plate and the disk are detachably connected, and the L-shaped structure of the fixing plate is adapted to the fixing requirements of the mounting plate to ensure stable installation of the scanner.

[0015] Preferably, the scanning head is a high-precision three-dimensional scanning head, which is electrically connected to the scanner, and the scanning range of the scanning head covers the bamboo and wooden slips placed on the platform.

[0016] Preferably, the camera is a high-definition industrial camera, and the two cameras are located on both sides of the base. The camera's shooting angle is aimed at the bamboo slips on the surface of the platform to assist in text extraction and image recording.

[0017] Preferably, the processor is electrically connected to the scanner and camera. The processor has a built-in 3D modeling and text recognition algorithm, which can process scan data and image information simultaneously.

[0018] A method for using an integrated device for three-dimensional shape scanning and text extraction of bamboo and wooden slips includes the following steps:

[0019] Step 1: Equipment Assembly and Debugging: Install the light panel into the inner cavity of the glass stage using the interlocking blocks and slots, ensuring the moving wheels roll flexibly; install the telescopic rod onto the surface of the horizontal plate, fix the horizontal block with the connecting block, connect the column to the horizontal plate through the round bearing, adjust the disc angle and then fix the fixing plate with bolts; install the scanner and scanning head onto the surface of the mounting plate, connect the processor to the scanner and camera, and ensure that the signals of each component are connected.

[0020] Step 2, Placement and Positioning of Bamboo Slips: Place the bamboo slips to be processed stably on the placement platform on the glass stage, and adjust the position of the placement platform to ensure that the bamboo slips are within the working range of the scanning head and camera; according to the size of the bamboo slips and the placement angle, adjust the height of the scanning head by using the telescopic rod, and rotate the column to adjust the scanning angle to ensure complete scanning coverage;

[0021] Step 3, Lighting Adjustment: Based on the clarity of the characters on the surface of the bamboo slips and the ambient light, move the position of the light panel. Use the moving wheels to slide the light panel in the inner cavity to adjust the lighting angle and brightness, so as to avoid light reflection or shadows affecting the scanning effect.

[0022] Step 4, Scanning and Extraction: Start the scanner and camera. The scanning head performs a three-dimensional shape scan on the bamboo slips, and the camera simultaneously captures images of the surface of the bamboo slips. The scanned data and image information are transmitted to the processor in real time. The processor completes the three-dimensional model construction and text extraction through the built-in algorithm, and generates a visualization data file.

[0023] Step 5: Data verification and saving: Use the processor to view the generated 3D model and extracted text content. If there are any blurry or missing areas, adjust the scanning angle and the position of the supplementary light and then rescan. After confirming that the data is accurate, save and back up the files by category.

[0024] Step Six: Equipment Maintenance and Storage: After scanning is complete, turn off the power to all components and remove the bamboo slips; move the light panel to one end of the inner cavity and clean the dust from the scanning head and camera surface; loosen the bolts, adjust the position of the fixing plate and column, and store the equipment in a dry and ventilated place to avoid damage to the parts. All components are installed inside the housing, and a heat dissipation vent is opened on the top of the housing. The housing surface can be detachably connected to the placement rack.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. Integrated design improves efficiency and protects cultural relics: This device integrates 3D shape scanning, text extraction, and supplementary lighting functions, eliminating the need for multiple devices to work together. Scanning and extraction are performed simultaneously, significantly reducing the digitization time of bamboo and wooden slips and improving efficiency by more than 60% compared to traditional methods. The entire process is non-contact, and the precise positioning with the placement platform avoids secondary damage such as wear and deformation caused by human contact, thus ensuring the protection of precious cultural relics. The scanner and camera work together, combined with the processor's intelligent algorithm, to obtain accurate 3D shape data and efficiently extract blurred or faded text information, improving data integrity and accuracy.

[0027] 2. Flexible adjustment to meet diverse needs and enhance practicality: The adjustment control component uses a telescopic rod to adjust the height of the scanning head, and with the help of a circular bearing to rotate the column, the scanning angle can be adjusted 360° to accommodate bamboo slips, wooden slips, fragments, etc. of different sizes and shapes; In the convenient lamp replacement component, the lamp plate can be flexibly adjusted in position and angle through the insert and the moving wheel, providing targeted supplemental lighting to eliminate shadows and solve the problem of unclear text recognition on the surface of the bamboo slips; The L-shaped fixing plate, with the cooperation of bolts and the multi-screw holes of the disc, can quickly switch the installation angle to meet the scanning needs under different placement methods, greatly improving the equipment's adaptability to complex scenarios.

[0028] 3. Balancing ease of operation and stable performance, lowering the barrier to entry: The modular design of the equipment allows for easy assembly and disassembly of components such as the light panel and scanner, facilitating transportation and maintenance. The combination of casters and slots makes adjusting the supplementary lighting effortless. The base and vertical plate form a stable support structure, and the precise positioning of the camera and scanning head ensures long-term operational stability. The processor incorporates automated algorithms, simplifying the data processing workflow. Operators do not need specialized digitization skills to complete scanning and extraction, lowering the technical threshold for cultural relic research and preservation, and facilitating its widespread application in museums, archaeological sites, and other similar settings.

A method of using the integrated device for three-dimensional shape scanning and text extraction of bamboo and wooden slips as described in claim 9, characterized in that: Includes the following steps: Step 1, Equipment Assembly and Debugging: Install the light panel (204) in the inner cavity (202) of the glass stage (201) through the interlocking block (205) and the slot (203), ensuring that the moving wheel (206) rolls flexibly; install the telescopic rod (401) on the surface of the horizontal plate (3), fix the horizontal block (403) through the connecting block (402), connect the column (405) to the horizontal plate (3) through the round bearing (404), adjust the angle of the disc (406) and fix the fixing plate (409) with the bolt (408); install the scanner (502) and the scanning head (503) on the surface of the mounting plate (501), connect the processor (504) to the scanner (502) and the camera (506), and ensure that the signals of each component are connected; Step 2, Placement and Positioning of Bamboo Slips: Place the bamboo slips to be processed stably on the placement platform (6) on the surface of the glass stage (201), adjust the position of the placement platform (6) to ensure that the bamboo slips are within the working range of the scanning head (503) and the camera (506); adjust the height of the scanning head (503) by means of the telescopic rod (401) according to the size of the bamboo slips and the placement angle, and rotate the column (405) to adjust the scanning angle to ensure complete scanning coverage; Step 3, Lighting adjustment: Based on the clarity of the characters on the surface of the bamboo slips and the ambient light, move the position of the light plate (204), and use the moving wheel (206) to drive the light plate (204) to slide in the inner cavity (202) to adjust the lighting angle and brightness, so as to avoid light reflection or shadows affecting the scanning effect; Step 4, Scanning and Extraction: Start the scanner (502) and camera (506). The scanning head (503) performs a three-dimensional morphological scan on the bamboo and wooden slips, and the camera (506) simultaneously captures images of the surface of the bamboo and wooden slips. The scan data and image information are transmitted to the processor (504) in real time. The processor (504) completes the three-dimensional model construction and text extraction through the built-in algorithm to generate a visualization data file. Step 5: Data verification and saving: Use the processor (504) to check the generated 3D model and extracted text content. If there are any blurry or missing areas, adjust the scanning angle and the position of the supplementary light and then rescan. After confirming that the data is accurate, save the files by category and back them up. Step 6, Equipment Maintenance and Storage: After scanning, turn off the power to each component and remove the bamboo slips; move the light board (204) to one end of the inner cavity (202) and clean the dust on the surface of the scanning head (503) and camera (506); loosen the bolts (408), adjust the position of the fixing plate (409) and the column (405), and store the equipment in a dry and ventilated place to avoid damage to the components. Each component is installed inside the housing (7), and the top of the housing (7) has a heat dissipation vent (9). The surface of the housing (7) can be detachably connected to the upper placement rack (8).
