Description

Technical Field

[0001] The present invention relates to the technical field of geological radar intelligent data interpretation, and more specifically, to a geological radar intelligent data interpretation method, equipment and medium that fuses multi-source data. Background Art

[0002] As the main engineering geophysical exploration method currently used for urban road disease detection, geological radar has the advantages of high resolution, non-destructive detection, continuous measurement, short data acquisition and processing time, and real-time imaging in the detection of urban road diseases such as underground cavities. In addition, geological radar can also help engineers understand the characteristics and structure of map layers. It has been widely used in the detection of underground cavity diseases in roads.

[0003] Although geological radar has many advantages, it also has certain limitations. Due to the complexity of the underground environment and the propagation mechanism of electromagnetic waves, it is difficult for the target echo profile to intuitively reflect the underground detection object. The interpretation mainly relies on the personal experience of the data interpreter. The data interpretation results are usually very subjective and may lead to erroneous interpretation results. As geological radar is widely used in various fields, the processing, analysis and interpretation of geological radar data and images have become increasingly important. At the same time, when interpreting geological radar data, there is often no data reference and only this single data is interpreted, which also has the problem of low interpretation accuracy. Summary of the invention

[0004] The purpose of the present invention is to provide a geological radar intelligent data interpretation method, device and medium that fuses multi-source data to solve the problems existing in the above-mentioned background technology.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: In the first aspect, the present application provides a method for intelligent data interpretation of geological radar by fusing multi-source data, including the following specific steps: Construct an initial model based on deep learning. The input of the initial model is the a-scan data of the geological radar, and the output of the initial model is the propagation speed of electromagnetic waves. The initial model is trained using preset training samples until the initial model reaches a preset training end condition, and the initial model that reaches the training end condition is determined as the interpretation model; Acquire the detection data of the geological radar in the area to be measured, and input the detection data into the interpretation model for processing to obtain the first velocity data of the electromagnetic wave in the underground medium in the area to be measured, the detection data includes a-scan data; Using the first velocity data and the historical seismic data of the area to be measured, a correlation coefficient between each data in the first velocity data and the historical seismic data is calculated; Based on each correlation coefficient, the first velocity data and each data in the historical seismic data are subjected to multi-source fusion processing, and the multi-source fusion result is determined as the target propagation velocity.

[0006] The beneficial effects of the present invention are as follows: in this scheme, firstly, the initial model based on deep learning is trained using the preset training samples, and when the training is completed, the initial model is determined as the interpretation model, and the interpretation model is mainly used to interpret the propagation speed of electromagnetic waves from the a-scan data of radar data. The propagation speed of electromagnetic waves is the propagation speed of electromagnetic waves in underground structures composed of different media. The propagation speed can be used to analyze the water content and other information in the underground structure, which can better meet the needs of radar in the field of water content detection; secondly, the detection data of the geological radar in the test area is obtained, and the detection data includes a-scan data. an data, and then the a-scan data in the detection data is input into the interpretation model for processing, so as to obtain the first velocity data predicted by the interpretation model, that is, the propagation velocity of electromagnetic waves in the area to be measured; finally, the various data in the seismic data are used with the first velocity data for multi-source fusion processing, and finally the accurate target propagation velocity of electromagnetic waves in the area to be measured is obtained; the seismic data mainly uses the propagation velocity data of longitudinal waves, shear waves and surface waves, that is, the same type of data; the multi-source fusion processing of multiple data can make the final electromagnetic wave propagation velocity more accurate, which can provide a reference for on-site construction, etc.

[0007] Based on the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the above interpretation model is obtained in the following way: Acquire simulation data of geological radar, the simulation data including a-scan data, geological simulation model data and simulation speed data, add preset noise to the a-scan data, and determine the simulation data with preset noise added as training samples; The a-scan data in the training sample is input into the initial model for processing to obtain the predicted speed, and the loss function of the initial model is calculated based on the predicted speed corresponding to the a-scan data and the corresponding simulation speed data; If the loss function does not exceed the threshold or the number of training iterations reaches the maximum number of iterations, the initial model is determined as the interpretation model, and the preset training end condition is that the loss function does not exceed the threshold or the number of training iterations reaches the maximum number of iterations.

[0009] The beneficial effect of adopting the above further scheme is that simulation data can be obtained through simulation experiments, and the corresponding simulation velocity data can be obtained by simulating the propagation of geological radar in the geological simulation model. The geological simulation model data includes the geological structure and component composition in the geological simulation model, and this data can be used as real data to effectively train the initial model.

Therefore, in order to obtain better model performance, the learning rate can be dynamically adjusted during training to avoid problems such as premature convergence of the model or oscillation caused by excessive learning rate; the learning rate can be reduced by the cosine function, which can also avoid parameters such as weight parameters from falling into the local minimum and reduce the time loss of model training.

The exponential weights that reach the iteration end condition are used to perform multi-source fusion of each data in the historical seismic data and the first velocity data to obtain the multi-source fusion result.

[0014] Furthermore, the above correlation coefficient is specifically: ; In the formula, Indicates the historical earthquake data n The correlation coefficient between the data and the first speed data, Indicates the coordinates of the first velocity data in the preset spatial rectangular coordinate system ( x, y, z ), Indicates the historical earthquake data n The coordinates of each data in the preset spatial rectangular coordinate system ( x, y, z ) at .

[0025] In the description of the embodiments of the present invention, "plurality" means at least 2.

[0026] Embodiment 1: In order to solve the problem that the current interpretation of geological radar mainly relies on the personal experience of data interpreters, the data interpretation results are usually highly subjective, which may lead to erroneous interpretation results, and when interpreting geological radar data, there is often no data reference and only this single data is interpreted, which also has the problem of low interpretation accuracy; this embodiment provides a geological radar intelligent data interpretation method that integrates multi-source data, such as Figure 1 As shown, the following specific steps are included: S1, build an initial model based on deep learning. The input of the initial model is the a-scan data of the geological radar, and the output of the initial model is the propagation speed of electromagnetic waves.

[0027] Among them, the initial model based on deep learning can be a U-net model, in which the multi-scale features in the geological radar a-scan data can be fully mined by combining with spatial pyramid pooling, so as to achieve the purpose of accurately predicting the propagation speed of electromagnetic waves from the a-scan data; specifically, the a-scan data of the geological radar is a single-channel waveform diagram.

[0028] S2, using preset training samples to train the initial model until the initial model reaches a preset training end condition, and determining the initial model that reaches the training end condition as the interpretation model.

[0029] Optionally, the above interpretation model is obtained by: S21, obtaining simulation data of geological radar, the simulation data including a-scan data, geological simulation model data and simulation speed data, adding preset noise to the a-scan data, and determining the simulation data with preset noise added as training samples.

[0030] Among them, due to the complexity of the actual detection environment, the data collected by the actual geological radar has a lot of clutter interference compared with the radar simulation data. Therefore, 0.35-0.85 Gaussian noise can be randomly added to the constructed training samples.

[0031] Specifically, simulation data can be obtained through simulation experiments, and the corresponding simulation velocity data can be obtained by simulating the propagation of geological radar in the geological simulation model. The geological simulation model data includes the geological structure and component composition in the geological simulation model. This data can be used as real data to effectively train the initial model.

[0032] S22, input the a-scan data in the training sample into the initial model for processing to obtain the predicted speed, and calculate the loss function of the initial model based on the predicted speed corresponding to the a-scan data and the corresponding simulation speed data. The loss function can be an MSE function.

[0033] Optionally, the weight parameters of the initial model are iteratively updated in the following way: ; In the formula, Indicates t The weight parameters of the initial model at this iteration, Indicates t -1 is the weight parameter of the initial model at this iteration, Indicates t The learning rate of the initial model at this iteration, Indicates t -1 The value of the loss function of the initial model at this iteration.

[0034] Specifically, in deep learning models, static learning rates are often not flexible enough and can easily cause the model to fall into a local minimum. Therefore, in order to obtain better model performance, the learning rate can be adjusted dynamically during training to avoid problems such as premature model convergence or oscillation caused by excessive learning rates; the learning rate can be reduced through a cosine function, which can also prevent parameters such as weight parameters from falling into a local minimum and reduce the time loss of model training.

[0035] S23, if the loss function does not exceed the threshold or the number of training times reaches the maximum number of iterations, the initial model is determined as the interpretation model, and the preset training end condition is that the loss function does not exceed the threshold or the number of training times reaches the maximum number of iterations.

[0037] Among them, when processing the detection data of the geological radar in the measured area, that is, when processing the measured data of the measured area, it can first be processed by removing direct waves, removing background noise, bandpass filtering, etc., and then the a-scan data in the detection data is input into the interpretation model. The output of the interpretation model is the propagation speed of electromagnetic waves in various underground media, that is, the first speed data.

[0038] S4, using the first velocity data and the historical seismic data of the area to be measured, calculate the correlation coefficient between the first velocity data and each data in the historical seismic data.

[0039] Among them, the seismic data mainly uses the data of the propagation speed of longitudinal waves, transverse waves and surface waves, that is, the same type of velocity data; seismic data can be obtained through various detection equipment when an earthquake occurs.

[0040] Optionally, the above correlation coefficient is specifically: ; In the formula, Indicates the historical earthquake data n The correlation coefficient between the data and the first speed data, Indicates the coordinates of the first velocity data in the preset spatial rectangular coordinate system ( x, y, z ), Indicates the historical earthquake data n The coordinates of each data in the preset spatial rectangular coordinate system ( x, y, z ) at .

[0041] Among them, the preset spatial rectangular coordinate system can take the position of the geological radar as the coordinate origin, set the x and y axes in the horizontal direction, and set the z axis in the vertical direction; the first velocity data records the velocity value of each coordinate point in the coordinate system; similarly, the historical seismic data also records the velocity value of each coordinate point in the coordinate system (the velocity values ​​of longitudinal waves, shear waves and surface waves).

[0042] S5, based on each correlation coefficient, performing multi-source fusion processing on each data in the first velocity data and the historical seismic data, and determining the multi-source fusion result as the target propagation velocity.

[0043] Optionally, the multi-source fusion result of the multi-source fusion processing is specifically: ; In the formula, represents the multi-source fusion result of multi-source fusion processing, Indicates the first speed data, Indicates the first data in the historical earthquake data.

[0045] Optionally, the exponential weight of each data in the above historical earthquake data is obtained by: S51, based on the preset initial value of the exponential weight of each data, preliminarily fuse the first velocity data with each data in the historical seismic data to obtain a first result.

[0046] S52, using the first result to calculate the loss values ​​corresponding to the exponential weights of each data in the historical earthquake data, and using the loss values ​​of each data in the historical earthquake data to recalculate the corresponding exponential weights.

[0047] Optionally, the loss values ​​corresponding to the exponential weights of the various data in the above historical earthquake data are specifically: ; In the formula, Indicates the historical earthquake data k The loss value corresponding to the exponential weight of each data point is: Indicates that the index weight is i The fusion result after the iteration update is: represents the simulation speed data corresponding to the first speed data, n Indicates the maximum number of iterations.

[0048] S53, using the recalculated exponential weights of each data to fuse with the first velocity data and iterate until the loss value corresponding to each exponential weight reaches the iteration end condition, using the exponential weights that reach the iteration end condition to perform multi-source fusion of each data in the historical seismic data and the first velocity data and obtain a multi-source fusion result.

[0049] Among them, the above-mentioned iterative process is: 1. presetting the initial value of the exponential weight; 2. fusing with the first speed data to obtain the first result; 3. using the first result to calculate the loss value of each exponential weight. When the loss value does not reach the iteration end condition, repeat 2-3 until the iteration end condition is reached; specifically, the iteration end condition can be reaching the maximum number of iterations.

[0050] Optionally, the corresponding index weights are recalculated using the loss values ​​of each data in the historical earthquake data, specifically: ; In the formula, represents the recalculated exponential weight, represents the exponential weight before updating, represents the learning rate of the interpretation model, Indicates the loss value corresponding to the exponential weight in the current iteration number.

The interpretation model is mainly used to interpret the propagation speed of electromagnetic waves from the a-scan data of radar data. The propagation speed of electromagnetic waves is the propagation speed of electromagnetic waves in underground structures composed of different media. The propagation speed can be used to analyze information such as water content in underground structures, which can better meet the needs of radar in the field of water content detection. Secondly, the detection data of the geological radar in the test area is obtained, and this detection data includes a-scan Data is obtained, and then the a-scan data in the detection data is input into the interpretation model for processing, so as to obtain the first velocity data predicted by the interpretation model, that is, the propagation velocity of electromagnetic waves in the area to be measured; finally, the various data in the seismic data are used with the first velocity data for multi-source fusion processing, and finally the accurate target propagation velocity of electromagnetic waves in the area to be measured is obtained; the seismic data mainly use the propagation velocity data of longitudinal waves, shear waves and surface waves, that is, the same type of data; the multi-source fusion processing of multiple data can make the final electromagnetic wave propagation velocity more accurate, which can provide a reference for on-site construction, etc.
