[0029] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0030] Example 1

[0031] like Figure 1As shown, the first embodiment of the present application provides a method for displaying mine holographic data based on naked-eye 3D technology, including:

[0032] Step S10: Filter key information for 3D modeling by calculating similarity coefficients of geological data;

[0033] Screening out key geological data for building an accurate 3D model involves the following sub-steps:

[0034] Step S11, data preprocessing: preprocessing the original geological data, including data cleaning, format unification, etc., to ensure data quality and consistency;

[0035] Step S12, calculate the similarity coefficient: for each pair of geological data points (x i ,y i ,z i ) and (x j ,y j ,z j ), calculate the similarity coefficient S between them ij , Where exp represents the natural exponential function, which is an exponential function with the base of the natural logarithm e (approximately equal to 2.71828). In mathematical expressions, exp(x) usually represents e to the power of x, that is, e x , where the exp function is used to calculate the exponential part The purpose of the exponential function is to increase the similarity coefficient S as the distance between two geological data points increases. ij will gradually decrease, because the negative sign in the exponential function will cause S to decrease as the exponent increases. ij The value of x quickly approaches 0; i ,y i ,z i represents the coordinate value of the i-th geological data point in three-dimensional space; x j ,y j ,z j Represents the coordinate value of the j-th geological data point in three-dimensional space; σ represents the standard deviation, which is used to control the decay rate of the similarity coefficient. A larger σ indicates a wider decay range, and a smaller σ indicates a narrower decay range; when the distance between two geological data points is small (i.e. Small), similarity coefficient S ij Close to 1, it means that the two points are very similar. When the distance between two geological data points is large, the similarity coefficient S ij A rapid decrease close to 0 indicates that the two points are not similar. Through this calculation method, key geological data information can be screened out for subsequent 3D modeling.

[0036] Step S13, screening key information: according to the calculated similarity coefficient S ij , select data points with similarity coefficient higher than a certain threshold T for 3D modeling, that is: if S ij >T, then keep the data point (x i ,y i ,z i ) and (x j ,y j ,z j ).

[0037] Step S20: constructing and optimizing a three-dimensional model of the geological structure using the calculated similarity coefficient;

[0038] Using the calculated similarity coefficient, constructing and optimizing the 3D model of the geological structure includes the following sub-steps:

[0039] Step S21, 3D model initialization: select appropriate 3D modeling software according to project requirements, such as Autodesk Maya, Blender, etc.; import the key geological data screened in step S10 into the modeling software; create a preliminary 3D model basic shape based on the distribution of geological data.

[0040] Step S22, model optimization: using the calculated similarity coefficient S ij , adjust the geometric parameters in the model to ensure the accuracy and realism of the model; reduce the irregularities of the model surface through surface smoothing algorithms to improve the model quality; add necessary details to the model according to the characteristics of geological data, such as rock layers, faults, etc.

[0041] Step S23, texture mapping: prepare texture maps of geological features, such as rock texture, soil texture, etc.; apply the prepared texture maps to the three-dimensional model to improve the realism of the model.

[0042] Step S24, model optimization and verification: check whether the model conforms to the actual characteristics of the geological structure; compare the error between the model and the actual geological structure, and make adjustments if necessary; optimize the rendering performance of the model to ensure smooth display under different hardware conditions.

[0043] Step S25, model interaction function development: design the interactive functions of the model, such as zooming, rotating, etc.; write code to implement the interactive functions to ensure that users can easily manipulate the model.

[0044] Step S26, model export and integration: export the optimized model into a format compatible with naked-eye 3D display technology; import the model file into the display system for system integration.

[0045] Step S30: Analyze user interaction frequency and preferences, optimize the interactive interface design, and ensure user friendliness;

[0046] To optimize the interactive interface, provide a personalized user experience, analyze user interaction frequency and preferences, optimize the interactive interface design, and ensure user friendliness, the following steps are included:

[0047] Step S31, user behavior recording: the system records the user's interactive behavior, including but not limited to click, slide, zoom and other operations; the collected behavior data is stored in the database for subsequent analysis.

[0048] Step S32, data analysis: count the frequency of users' use of specific functions or interface elements; analyze the functions and content that users use most frequently and pay most attention to based on their usage habits and preferences; identify users' typical behavior patterns, such as common operation sequences or browsing paths.

[0049] Step S33, interface optimization: adjust the layout of interface elements according to user preferences to make commonly used functions easier to access; simplify the operation process, reduce unnecessary steps, and improve operation efficiency; provide personalized operation suggestions or content recommendations based on the user's preference history; adjust visual elements such as color and font to improve the overall aesthetics and readability of the interface.

[0050] Step S34, user feedback collection: collect users' opinions and suggestions on interface design through questionnaires; conduct face-to-face or online interviews with users to gain an in-depth understanding of their usage experience and needs; invite users to participate in the testing of new versions of the interface to obtain direct feedback.

[0051] Step S35, continuous iterative improvement: Create a new version of the interface prototype based on user feedback and data analysis results; conduct A / B testing to compare the effects of different design solutions; and continuously optimize the interface design based on test results and user feedback.

[0052] Step S40, calculating and adjusting naked-eye 3D display parameters according to the user's viewing position and angle to achieve the best stereoscopic visual effect, includes the following sub-steps:

[0053] Step S41: Obtain the user's position coordinates: obtain the user's three-dimensional coordinates (x, y, z) in space through sensors installed around the display device (such as depth cameras, infrared sensors, etc.); calculate the distance between the user and the display plane. Assuming that the coordinates of the center point of the display plane are (x0, y0, z0), the distance between the user and the display plane is

[0054] Step S42: Determine the user's viewing angle parameters: Obtain the user's head orientation vector, also using the sensor to obtain the user's head orientation vector Assume that the range of the display plane in the x, y, and z directions is [x min ,x max ]、[y min ,y max ]、[z min ,z max ], then the plane normal vector is displayed in The unit vectors of the three coordinate axes respectively; calculate the user's line of sight vector By user head vector Display plane normal vector To calculate the user's line of sight vector, which is used to represent the direction of the user's line of sight; calculate the angle between the user's line of sight and the display plane in represents the user's sight vector, represents the normal vector of the display plane, and θ represents the angle between the user's line of sight and the display plane.

[0055] Step S43: Calculate the naked eye 3D display parameters. First, calculate the parallax adjustment amount. Assume that the original binocular parallax is p0, and the parallax adjustment amount Δp = g(d, θ). The g function is defined as follows: Here, k1, k2, k3, and k4 are coefficients determined through extensive experiments. i is a summation variable that starts at 1 and increases to n. d is the distance between the user and the display plane. θ is the angle between the user's line of sight and the display plane. ∈ is a very small positive number to prevent the denominator from being zero. n is a positive integer that can be adjusted based on actual conditions. The adjusted binocular parallax p = p0 + Δp. The pixel offset Δx = p·s is calculated based on the binocular parallax p and the pixel spacing s of the display device.

[0056] Step S44: Adjust the naked-eye 3D display. Perform a pixel offset operation on the left and right images of the display device according to the calculated pixel offset Δx to adjust the naked-eye 3D effect. Continuously monitor the user's position and angle changes. When the user's position or angle changes, repeat the above steps and adjust the naked-eye 3D display parameters in real time to ensure that the best stereoscopic visual effect is always maintained.

[0057] Step S50: Integrate the results of the above steps, perform system integration, and evaluate the response time and stability of the system to ensure reliability.

[0058] Integrate the modules developed in steps S10 to S40 into a complete system, define the communication protocols and data exchange formats between the modules, and conduct preliminary system debugging and testing to ensure that the modules can work together; test the system's response time and stability, simulate various failure scenarios, evaluate the system's failure recovery capabilities, and run the system under high load to evaluate its performance limits and stability.
