[0030] The following will be combined with the embodiments of the present invention and the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1:

[0032] See also Figure 1-2 , an industrial heritage transformation analysis device based on animation model, comprising a data acquisition module, a three-dimensional modeling module, an animation generation module, a virtual reality display module and an analysis report generation module, wherein the data acquisition module is used to obtain external morphological data and internal structural information of industrial heritage, the three-dimensional modeling module is used to convert the collected data into a high-precision three-dimensional model, the animation generation module is used to create a dynamic scene based on the three-dimensional model, the virtual reality display module is used to allow a user to immersively experience the current status of the heritage and the visual effects after transformation through VR equipment, and the analysis report generation module is used to output specific transformation suggestions and implementation plans.

[0033] In the first embodiment, the drone in the data acquisition module uses the DJI Phantom 4 RTK series drone, which is equipped with a 1-inch 20-megapixel camera and a high-precision RTK positioning system, which can achieve centimeter-level positioning accuracy. The drone has high flight stability and a wind resistance of up to level 5, and can perform aerial photography operations in complex environments;

[0034] Before taking aerial photos of industrial heritage, we use professional drone route planning software to plan the flight route according to the scale and shape of the heritage, and set the flight altitude between 20-80 meters to ensure that we can get the overall picture of the heritage and capture the detailed features. For example, for large industrial plants, we first take a bird's-eye view of the plant at a height of 50 meters, and then take multi-angle photos around the plant at a height of 20 meters. The shooting angles include 0° (horizontal direction), 45° (tilted direction) and 90° (vertical direction), etc. The distance between adjacent shooting points is set to 5-10 meters according to the size of the plant to ensure that there is enough overlap between the images to facilitate subsequent 3D modeling.

[0035] The drone automatically flies and takes images according to the preset route. Ensure sufficient light when shooting, and try to choose to operate between 10 am and 3 pm to avoid direct sunlight causing shadows that affect image quality. The acquired images are in RAW format for more accurate processing later. After the aerial photography is completed, the images are transmitted to the ground control station and preliminary processed using professional image processing software - Adobe Lightroom, including adjusting parameters such as exposure, contrast, and color balance to make the images clearer and more realistic.

[0036] In the first embodiment, the laser scanning unit uses a laser scanner such as the Focus S150 laser scanner, which has a scanning accuracy of up to 1 mm and a scanning distance of up to 150 meters, and can generate high-density point cloud data;

[0037] When performing laser scanning, scanning stations are reasonably arranged around the industrial heritage according to the terrain and architectural layout of the heritage. For complex terrain or large buildings, the scanning station spacing is set to 3-5 meters to ensure that there are no scanning blind spots. Each scanning station is set with multiple scanning angles, with a horizontal angle interval of 30°-45° and a vertical angle coverage range of -45° to 45° to obtain all-round shape and size information of the heritage. During the scanning process, a high-precision total station (such as Leica TS16) is used to coordinate the scanning station to ensure accurate stitching of scanning data from different stations. After the scanning is completed, the scanner's supporting software - FARO Scene is used to perform pre-processing operations such as stitching and denoising on the original point cloud data to remove noise points caused by environmental factors (such as dust, fog, etc.) and improve the quality of point cloud data.

[0038] In the first embodiment, the 3D modeling module imports the point cloud data acquired and preprocessed by the laser scanning unit into the 3D modeling software - Geomagic Wrap, and first simplifies the data. According to the distribution density of the point cloud and the model accuracy requirements, an adaptive sampling algorithm is used to reduce the data volume and improve the processing efficiency while ensuring the model characteristics. Then, outliers are removed. By calculating the statistical characteristics of the distance between each point and its neighboring points, points with a distance mean exceeding 3 times the standard deviation are determined as outliers and deleted;

[0039] The surface reconstruction adopts the surface reconstruction algorithm based on the moving least squares method. For each point P in the point cloud i , select its neighboring point k (the value of k is determined according to the point cloud density and model complexity, generally 10-20), construct a local weighted least squares fitting plane, and minimize the objective function:

[0040]

[0041] where w j is the weight function, according to Pj Click to P i The distance between the points is determined, and the closer the distance, the greater the weight; P j The projection of the point on the fitting plane; thereby solving the parameters of the fitting plane and determining P i The points are adjusted to obtain a continuous and smooth surface model.

[0042] In the first embodiment, the texture image preprocessing is to further process the image acquired and processed by the drone aerial photography unit, separate the main body of the industrial heritage from the background in the image by using an image segmentation algorithm (such as a segmentation algorithm based on region growing), and then perform image enhancement processing on the main part to improve the clarity of texture details;

[0043] The mapping operation is to map the preprocessed texture image to the model surface in the 3D modeling software according to the geometric shape of the 3D model and the posture parameters of the drone during shooting. The texture mapping method based on feature point matching is adopted. First, feature points (such as corner points, edge points, etc.) are extracted on the model surface and the texture image, and the corresponding relationship of the feature points is established through the matching algorithm (such as SIFT algorithm). Then, the mapping transformation matrix is ​​calculated according to the corresponding relationship, and the texture image is accurately mapped to the model surface, so that the model has a realistic appearance.

[0044] In the first embodiment, scene analysis and key frame planning:

[0045] Animation designers conduct in-depth analysis of different stages of industrial heritage transformation and possible dynamic changes. For example, for large-scale mechanical equipment in industrial heritage, their normal operation, start-up, stop and other states are analyzed; for building structures, the deformation process under different loads (such as wind loads, earthquake loads, etc.) is considered. Based on these analysis results, key frames are carefully designed. Taking mechanical equipment as an example, key frames include the static state of the equipment (initial key frame), key positions during the equipment startup process (such as the motor starts to rotate, the transmission parts start to link, etc.), the stable operation state of the equipment (such as the speed reaches the rated value, the various parts move smoothly, etc.) and the key positions during the equipment stop process (such as the brake parts start to work, the equipment gradually stops rotating, etc.). Each key frame records the position, posture, movement speed and other parameters of each part of the equipment in detail to ensure accurate expression of the action or state of the equipment.

[0046] Intermediate frame calculation principle:

[0047] For two adjacent key frames K1 and K2, let the time of K1 be t1, the time of K2 be t2, and the time interval of the intermediate frames be Δt. For any control point P in the model (which can be a model vertex, joint point, etc.), its position in K1 is P1, and its position in K2 is P2. Then the position of the control point in the intermediate frame (n=1,2,…) is calculated by the linear interpolation formula:

[0048]

[0049] It is calculated that for the model's posture (such as rotation angle) and other attributes (such as color change, etc.), a similar linear interpolation method is also used to calculate the intermediate values ​​to ensure the continuity and smoothness of the animation when transitioning between adjacent key frames;

[0050] After calculating the intermediate frames, the generated animation is optimized to check whether there are problems such as model interlacing and unnatural movement during the animation process. For the model interlacing problem, it is solved by adjusting the key frame parameters or adding constraints. For the unnatural movement problem, more advanced interpolation methods such as spline interpolation are used to smooth the animation curve to make the animation effect more realistic.

[0051] In the first embodiment, the VR device is an HTC Vive Pro 2 VR device, which has a 2448x2448 resolution display screen, can provide a clear visual experience, and is equipped with a Steam VR positioning system to achieve sub-millimeter tracking accuracy, ensuring that the user's operations in the virtual environment can be accurately fed back. At the same time, it is equipped with a high-performance computer host (such as an Intel Core i9 processor, an NVIDIA GeForce RTX3090 graphics card, 32GB of memory, etc.) to ensure the smooth operation of VR applications;

[0052] By using the Unity3D game development engine to develop a virtual reality display application, the program provides users with an intuitive interactive interface and operation method. For example, different functions can be switched through the handle buttons, objects can be selected by pressing the trigger button, and the object can be translated, rotated and scaled through the touchpad. For changing the lighting conditions, a special knob or button is set on the handle. Users can adjust the light intensity (in the range of 0-100%), light direction (by changing the azimuth and elevation of the light source, the azimuth range is 0°-360°, and the elevation range is -90°-90°) and light color (adjusted through the RGB color model, and the value range of each color component is 0-255) by rotating or pressing. In the virtual environment, the movement of objects and changes in lighting respond in real time, simulating the actual use of the heritage after transformation. Users can freely explore the scene effects under different transformation schemes.

[0053] In the first embodiment, the ANSYS Workbench structural analysis software is used to import the 3D model of the industrial heritage generated by the 3D modeling module into ANSYS Workbench in a suitable format (such as .STEP format). During the import process, the geometric shape, material properties and other information of the model are ensured to be accurate;

[0054] According to the actual building materials of the industrial heritage (such as the type of steel, the strength grade of concrete, etc.), the corresponding material parameters are set in ANSYS. For steel, the elastic modulus is set to 200GPa (may vary depending on the specific steel type), Poisson's ratio is set to 0.3, and the yield strength is set to 345MPa. For concrete, the compressive strength, elastic modulus and other parameters are set according to the strength grade. Then, according to the meteorological conditions and usage requirements of the area where the industrial heritage is located, the corresponding load is applied. For example, for wind load, the wind load size is calculated according to the local basic wind pressure, building shape coefficient and other parameters, and applied to the corresponding surface of the model; for snow load, the snow load value is calculated and applied according to the specification. Through the finite element analysis method, the model is discretized into a finite number of units (such as tetrahedral units, hexahedral units, etc.), and the stress and strain distribution of each unit under the load is calculated, so as to obtain the bearing capacity and durability indicators of each part of the heritage. The bearing capacity calculation formula is:

[0055] F=k·A

[0056] The material coefficient k in ANSYS is calculated based on the material properties of different materials, and the force area A is calculated based on the geometric dimensions of the model unit.

[0057] In the first embodiment, the economic cost accounting software is built on the basis of a database system. The database contains price information of various building materials, equipment, labor and other resources, and the price information is updated regularly to ensure the accuracy of cost accounting. At the same time, the software has a built-in cost accounting formula:

[0058] C=∑(P i Q i )+T.

[0059] According to the industrial heritage reconstruction plan, the software automatically identifies the various resources required; for example, it extracts the specifications and quantity of the required steel from the reconstruction design drawings, and obtains information such as man-hours from the construction plan. Then it queries the unit price of the corresponding resources from the database and calculates the cost of each resource. i Q iFor the time cost T, it is calculated based on factors such as the estimated project duration, the unit price of the participating personnel's working hours, and the equipment rental time. For example, the estimated project duration is 12 months, the average unit price of the construction personnel's working hours is 200 yuan / hour, they work 22 days a month, 8 hours a day, and the total number of construction personnel is 50. The labor time cost is 12×22×8×50×200 yuan. The equipment rental fee is calculated based on the type, quantity and rental time of the leased equipment. For example, if a crane is leased with a monthly rent of 50,000 yuan and a lease period of 6 months, the equipment rental cost is 50,000×6 yuan. Add up all the costs to get the total cost, which provides a detailed economic cost estimate for the renovation project in order to conduct an economic feasibility analysis.

[0060] During the entire industrial heritage transformation analysis process, each module works together in accordance with the above-mentioned embodiment 1; first, the data acquisition module obtains accurate data to provide a basis for three-dimensional modeling; the three-dimensional modeling module generates high-quality models to provide a carrier for animation generation and structural analysis; the animation generation module creates dynamic scenes to enhance visualization effects; the virtual reality display module allows users to experience immersion and assist in decision-making; the analysis report generation module provides scientific structural and economic analysis, and ultimately outputs comprehensive and feasible transformation suggestions and implementation plans; for example, in the transformation analysis of an abandoned steel plant, the overall appearance and structural data of the plant are obtained through drone aerial photography and laser scanning, a three-dimensional model is constructed, and animations such as equipment dismantling and building transformation are simulated based on the model, and the effects of different transformation plans are displayed in VR, and the structural strength and cost are analyzed to determine the best transformation plan.

[0061] In summary, the industrial heritage transformation analysis device and method based on the animation model significantly improves the efficiency and accuracy of data collection through the collaborative work of the data acquisition module and the three-dimensional modeling module. The data acquisition module includes a drone aerial photography unit and a laser scanning unit. The drone aerial photography unit obtains the appearance image of the industrial heritage from the air. The laser scanning unit accurately measures the size and shape of the heritage and generates point cloud data with a density of not less than 1,000 points per square meter to ensure the fineness of the model. The three-dimensional modeling module adopts point cloud-based surface reconstruction technology, solves the optimal position of each point through the least squares method, forms a continuous surface model, and applies texture mapping technology to map the drone aerial photography image to the three-dimensional model, thereby improving the realism of the model. It can not only quickly generate a high-precision three-dimensional model, but also comprehensively and accurately reflect the current status of the industrial heritage.

[0062] In addition, the industrial heritage transformation analysis device and method based on the animation model significantly enhances the visualization and operability of the transformation plan through the combination of a virtual reality display module and an analysis report generation module. The virtual reality display module supports users to immersively experience the current status of the industrial heritage and the visual effects after the transformation through VR equipment. Users can perform interactive operations in a virtual environment, such as moving objects, changing lighting conditions, and simulating the actual use of the heritage after transformation. This immersive experience enables decision makers and designers to understand the transformation effect more intuitively and discover potential problems in a timely manner. The analysis report generation module integrates structural strength analysis software and economic cost accounting software to calculate the bearing capacity and durability indicators respectively, and estimate the total cost, including direct cost and indirect cost, to provide scientific transformation suggestions and implementation plans, ensure the smooth progress of the project, and solve the problem that the existing evaluation methods mostly rely on manual on-site inspections and two-dimensional drawing analysis, which is not only inefficient, but also difficult to fully and accurately reflect the real situation of industrial heritage and its potential transformation possibilities.
