Detailed Implementation

[0015] This application provides a virtual reality-based method and system for displaying metrology technology, which solves the technical problem that metrology exhibition hall displays cannot fully demonstrate the development and current state of metrology technology, making it difficult for visitors to understand the history of metrology development. It achieves the technical effect of using metrology culture interpretation to allow visitors to reenact metrology stories, diversifying the display of the development and current state of metrology technology, and enabling visitors to fully understand the history of metrology development.

[0016] Example 1

[0017] like Figure 1 As shown, this application provides a method for displaying metrology technology based on virtual reality, wherein the method is applied to a metrology technology display system, the system being communicatively connected to a virtual reality system, and the method includes:

[0018] S100: Obtain historical metrology development information, wherein the historical metrology development information includes historical development nodes, historical metrology methods, and historical metrology category information;

[0019] S200: Device for acquiring historical characterization metrics;

[0020] S300: By merging the historical development information of metrology with the historical representative measurement device, a metrology culture information chain is obtained;

[0021] Specifically, the aforementioned information on the historical development of measurement includes historical development milestones (ancient measurement - four to five thousand years ago; modern measurement - 1875; contemporary measurement - 1960), historical measurement methods (ancient measurement - often using a part of the human body, other natural objects, or plant fruits as measurement standards, such as using a palm as a ruler, measuring an acre by a step, and measuring time by a drip of water; modern measurement - macroscopic physical standards guided by classical theory, such as the "prototype of the meter" and the "prototype of the kilogram"; contemporary measurement - the International System of Units, macroscopic physical standards based on classical theory). This will be converted into a microscopic natural benchmark based on quantum physics and fundamental physical constants, in order to maintain the long-term stability of the basic units; historical measurement category information (ancient measurement - length, volume, weight, and time; modern measurement - the "prototype meter" made based on the length of one forty-millionth of the length of the Earth's meridian, the "prototype kilogram" made based on the mass of one cubic decimeter of pure water at its maximum density, etc.; contemporary measurement - the unit of time "second", the unit of length "meter", the unit of voltage "volt", and the unit of resistance "ohm"), providing a foundation for subsequent data analysis;

[0022] Historical representative measurement devices are acquired, which may include solar corona, meter prototype, kilogram prototype, balance beam, and other related measurement devices. Based on the historical development nodes, the historical development information of measurement is sorted, and the historical representative measurement devices are used as embedded information. The information is merged to obtain the measurement culture information chain, providing data support for the interpretation of measurement culture.

[0023] Furthermore, such as Figure 2 As shown, by merging the historical development information of metrology with the historical representative measurement device, a metrological culture information chain is obtained. Step S300 further includes:

[0024] S310: Obtain historical typical measurement anecdotes;

[0025] S320: Extract typical measurement quotes from ancient books to obtain typical historical measurement quotes;

[0026] S330: The historical typical metrological anecdotes are used as the first supplementary information, and the historical typical metrological quotes are used as the second supplementary information. The information is merged to obtain the metrological culture information chain.

[0027] Specifically, this involves acquiring typical historical measurement anecdotes, such as using a cloth to measure a foot, taking a step to measure an acre, holding a handful to measure a liter, and Cao Chong weighing an elephant; extracting typical measurement quotes from ancient books, such as "Using a cloth to measure an inch, using a cloth to measure a foot" from the *Kongzi Jiayu* and "A kui is a single step, twice a kui is a step" from the *Xiao Erya*; using these typical historical measurement anecdotes as the first supplementary information and these typical historical measurement quotes as the second supplementary information, and merging the information through embedding to obtain a measurement culture information chain, thus providing a foundation for ensuring the comprehensiveness of the measurement culture information chain.

[0028] S400: Obtain the virtual IoT terminal in the metrology technology exhibition hall;

[0029] S500: By importing the metrological culture information chain through the virtual reality system, the environmental information of the virtual exhibition venue is obtained;

[0030] S600: The virtual IoT terminal carries the environmental information of the virtual exhibition venue;

[0031] S700: Set cultural performance level rules, input visitor information into the virtual Internet of Things terminal, and conduct level-based experiential measurement of cultural performance.

[0032] Specifically, a virtual IoT terminal is acquired in the metrology technology exhibition hall. This virtual IoT terminal utilizes AR technology and can typically be a head-mounted display (employing multimedia, 3D modeling, real-time video display and control, multi-sensor fusion, and other technologies). Through the virtual reality system, the metrology culture information chain is imported to acquire virtual exhibition venue environment information (creating an immersive, computer-generated environment). This virtual IoT terminal carries the virtual exhibition venue environment information. Cultural interpretation level rules are set, and visitor information is input into the virtual IoT terminal. Through the virtual IoT terminal, historical typical metrology anecdotes are presented in a leveled, experiential metrology culture interpretation, providing a foundation for visitors to participate in the cultural interpretation process and deeply understand the metrology culture framework.

[0033] Furthermore, the step S700 of setting cultural interpretation level rules includes:

[0034] S710: Obtain the age limit threshold for cultural performance;

[0035] S720: Obtain the cultural performance level by combining the visitor information with the age limit threshold for cultural performance, and information from educational materials at different stages;

[0036] S730: Generate cultural performance level rules based on the cultural performance level and the visitor information.

[0037] Specifically, the age limit for cultural interpretation can be set to 18 years old (adult). The age limit for cultural interpretation is then obtained. By combining the visitor age information in the visitor information with the age limit for cultural interpretation and the educational textbook information, a cultural interpretation level is obtained. This cultural interpretation level is a quantitative cultural interpretation level that is appropriate for the visitor's understanding. Information association mapping and organization are performed between the cultural interpretation level and the visitor information to generate cultural interpretation level rules, providing a basis for quantitative cultural interpretation within the visitor's comprehension range.

[0038] Furthermore, by combining the visitor information with the age limit threshold for cultural performance and the information from educational materials, the cultural performance level is obtained. Step S720 includes:

[0039] S721: Determine whether the visitor information meets the age limit threshold for the cultural performance;

[0040] S722: If the visitor information does not meet the age limit threshold for cultural performance, obtain the educational stage textbook information, wherein the educational stage textbook information includes educational textbooks of various versions and multiple subjects;

[0041] S723: Using the information from the textbooks at the aforementioned educational stages, assess the student's ability to understand the materials and obtain a level of comprehension ability.

[0042] S724: Obtain the cultural interpretation level based on the material comprehension level.

[0043] Specifically, the process involves determining whether the visitor information meets the age limit for cultural interpretation. If the visitor information does not meet the age limit (i.e., the visitor's age is less than 18), educational textbook information is obtained, including textbooks from various versions and multiple subjects. Using this educational textbook information, the material comprehension ability is assessed using the K-Medoids (center point) algorithm. Simply put, the most central object in the educational textbook information is selected as the center point, and the process iterates until the object distribution in the educational textbook information no longer changes. Once the object distribution no longer changes, the material comprehension ability level is obtained. Based on this material comprehension ability level, the corresponding cultural interpretation level is determined, providing a foundation for ensuring the feasibility of the cultural interpretation scheme.

[0044] Furthermore, such as Figure 3 As shown, the step S721 of determining whether the visitor information meets the age limit threshold for cultural performance includes:

[0045] S721-1: Obtain information about the characters and roles in historical anecdotes;

[0046] S721-2: If the visitor information meets the age limit threshold for the cultural performance, the visitor information is input into the virtual Internet of Things terminal;

[0047] S721-3: Through the virtual IoT terminal, the character information of the historical figures is assigned to conduct a level-based experiential measurement and cultural interpretation.

[0048] Specifically, the process involves identifying historical figures from typical metrological stories and obtaining their character information (such as Cao Chong, Cao Cao, and other officials in the story of Cao Chong Weighing the Elephant). If the visitor information meets the age limit for the cultural interpretation (i.e., the visitor's age is not less than 18 years old), the visitor information is input into a virtual IoT terminal. Through the virtual IoT terminal, the character information is assigned, and a graded experiential metrological cultural interpretation is conducted, providing a foundation for the restoration of historical typical metrological stories.

[0049] Furthermore, through the virtual IoT terminal, the character information of the historical figures is assigned. Step S721-3 includes:

[0050] S721-31: Collect visitor voice timbre information, visitor speech rate information, and visitor tone information through the virtual IoT terminal;

[0051] S721-32: Evaluate the matching degree between the timbre information and the intonation information of the visitors to obtain the performance matching degree;

[0052] S721-33: Determine the performance matching degree with the preset performance matching degree threshold, and generate a set of suitable roles for visitors;

[0053] S721-34: Using the visitor's speech rate information as a limitation, filter the visitor's role set to obtain the visitor role set;

[0054] S721-35: Send the set of visitor roles to the visitor terminal, select the personalized dialogue for role performance, and assign the role information of the characters from the historical allusions.

[0055] Specifically, data is collected through the virtual IoT terminal, acquiring visitor voice timbre, speech rate, and tone information; the TOPSIS method (Technique for Order Preference by Similarity to Ideal) is then employed. The Sulution method (using a distance-based approach) is used to evaluate the matching degree. Specifically, the timbre and intonation information of the visitors are normalized. The best and worst matching features are found using the cosine method. Then, the distance between each evaluation object and the best and worst matching features is calculated to obtain the relative closeness between each evaluation object and the best matching feature. This is used as the basis for evaluation to obtain the deductive matching degree. The deductive matching degree is compared with a preset deductive matching degree threshold (a preset parameter index). If the deductive matching degree is greater than the preset deductive matching degree threshold, the character information of the allusion corresponding to the deductive matching degree is set as an element of the visitor's suitable character set. The allusion character information is traversed to generate the visitor's suitable character set. The visitor's speech rate information is used as limiting information to filter the visitor's suitable character set and obtain the visitor's character set. The visitor's character set is sent to the visitor's terminal, where the visitor selects the character interpretation personality and assigns the allusion character information, providing support for increasing the fun of interpreting metrological culture and improving the display effect of metrological technology.

[0056] In summary, the virtual reality-based metrology technology demonstration method and system provided in this application have the following technical effects:

[0057] By employing the following methods and systems—namely, acquiring historical metrology development information; acquiring historical representative measurement devices; merging historical metrology development information with historical representative measurement devices to obtain a metrology culture information chain; acquiring virtual Internet of Things (IoT) terminals; importing the metrology culture information chain into a virtual reality system to obtain virtual exhibition venue environment information; transporting the virtual exhibition venue environment information through the virtual IoT terminal; and setting cultural interpretation level rules, inputting visitor information into the virtual IoT terminal for level-based experiential metrology culture interpretation—this application provides a metrology technology display method and system based on virtual reality. This achieves the goal of using metrology culture interpretation to allow visitors to recreate metrology anecdotes, diversifying the display of metrology technology development and current metrology technologies, and enabling visitors to fully understand the technological effects of metrology development history.

[0058] By employing an age-limited threshold for cultural interpretation, and combining the visitor information with the age-limited threshold for cultural interpretation, along with information from educational materials, a cultural interpretation level is obtained. Furthermore, by combining this visitor information with rules for generating cultural interpretation levels, a foundation is provided for measuring cultural interpretation within the visitor's comprehension.

[0059] By using the virtual IoT terminal to collect visitor voice timbre, speech rate, and intonation information, and conducting a matching degree assessment to obtain a performance matching degree; judging the performance matching degree against a preset performance matching degree threshold to generate a set of suitable roles for visitors; and using the visitor speech rate information as a limit for filtering to obtain a set of visitor roles, which is then sent to the visitor's terminal for personalized role performance selection and assignment of the historical figures' role information, support is provided to increase the fun of interpreting metrology culture and enhance the display effect of metrology technology.
