Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of geological disaster prevention and control, and in particular to an open-air slope landslide body identification and early warning system and method based on infrared local warming effect. Background Art
[0002] Slope landslide is one of the common geological disasters, which seriously threatens the safety of human life and property and has a huge impact on social and economic activities. Early identification and early warning of landslides are the basis of disaster prevention and mitigation work and the key to effectively reducing the losses caused by landslide disasters. However, traditional landslide identification methods often rely on manual surveys, which are inefficient and easily limited by the experience and knowledge level of staff. The situation at the project site is complex and changeable. In addition to the warming phenomenon of the landslide body itself, pedestrians, buildings, water bodies and forests in the surrounding environment may also show local warming phenomena. The warming interference of these non-landslide bodies often leads to misjudgment and distortion, which greatly affects the accuracy of landslide body identification.
[0003] With the development of science and technology, infrared thermal imaging technology, as a non-contact, real-time monitoring method, has gradually been applied to landslide identification research. By monitoring the slope area with an infrared thermal imager, the signal of local warming can be captured before the landslide occurs, thus providing an important basis for early warning of landslides. Although traditional image processing methods can perform preliminary identification of landslide bodies when processing a large number of thermal images, their efficiency is low and it is difficult to effectively solve the noise and interference problems in the image. Especially in complex natural environments, the similarity between landslide bodies and other warming phenomena has a significant impact on the accuracy and reliability of the identification results.
[0004] During open-pit mining, slopes are often subjected to stress disturbances, which can lead to a decrease in slope stability, increase the risk of landslides, and directly threaten the safety of mine production and the lives and property of workers. Therefore, it is of great practical significance to conduct non-contact accurate identification of open-pit slope landslides. Summary of the invention
[0005] In view of the defects of the prior art, the present invention provides an open-air slope landslide body identification and early warning system and method based on infrared local warming effect.
[0006] In order to achieve the above invention object, the technical solution adopted by the present invention is as follows:

[0019] Furthermore, the local temperature increase area in the infrared thermal image corresponds to the active area of the landslide body. The activity of the landslide body is accompanied by soil friction and pressure changes, which leads to local temperature increase. The local temperature increase area is the area where the landslide body may occur.
[0020] Furthermore, the open-air slope landslide body identification and early warning system can monitor the slope area remotely and contactlessly, and issue landslide early warning signals in advance through real-time data processing and analysis.

[0024] Step 3: Based on the identified local warming areas, combined with geological and meteorological data, analyze and evaluate the potential risks of landslides and issue landslide warning signals.
[0025] Furthermore, the evaluation criteria of the infrared local warming intelligent identification model include:

[0031] Furthermore, the local temperature increase area corresponds to the active area of the landslide body, and the active area may indicate the occurrence of a landslide.
[0032] Furthermore, the landslide warning signal is issued based on the location, scope and risk assessment results of the landslide activity area.

[0050] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and examples.
[0051] 1. Intelligent identification system construction and testing
[0052] (1) Construction of intelligent recognition model dataset
[0053] Infrared monitoring tests of uniaxial loading fracture of marble and granite were carried out in the early stage, and it was found that the infrared thermal images of rocks changed from overall warming to local IRT strengthening, corresponding to the localization of fractures and stress regional concentration. For example, compressive shear stress concentration corresponds to IRT high temperature aggregation, tensile stress concentration corresponds to IRT low temperature differentiation, shear cracks are IRT high temperature strips, tensile cracks are IRT low temperature strips, covering type is IRT high temperature aggregation, and covering-uncovering type is related to the stress state of exposed rocks. During the deformation and destruction of rocks, there are a total of four types of local warming, namely regional high temperature aggregation, point-like high temperature aggregation, strip-like high temperature aggregation and high temperature dust radiation flow.
[0054] 104 thermal images with significant local warming phenomena were selected from the obtained thermal images to construct the data set. In order to improve the generalization ability of the intelligent recognition model, data enhancement techniques (such as rotation, flipping, scaling, etc.) were used to expand the data set size ( Figure 1 ), the total number of enhanced thermal image data sets reached 416. The infrared thermal image change map was segmented using the image segmentation model SAM (SegmentAnything Model) to generate a segmentation mask map containing the local temperature increase area ( Figure 2 ). Store the segmentation mask image in the same (Segmentation) folder to complete the data set creation.
[0055] (2) Model selection
[0056] like Figure 3 As shown in the figure, the deep learning network model selected by the intelligent recognition system is U-Net. U-Net is a deep learning network model designed for image segmentation tasks. Its structure is "U"-shaped and mainly consists of two parts: encoder and decoder. As a variant of the Fully Convolutional Network (FCN), U-Net was first proposed in image segmentation in the biomedical field and has now been extended to multiple application fields such as satellite imaging and autonomous driving. In the encoder part of U-Net, the resolution of the input image is gradually reduced through multi-layer convolution and pooling operations to extract high-level semantic features. The convolution layer is used to capture the high-level features of the image, and the pooling layer implements the downsampling process to reduce the size of the feature map. This process is repeated, allowing the network to gradually focus on more abstract information. The decoder part is the opposite of the encoder, and the low-resolution feature map is gradually upsampled to the resolution of the original image. Upsampling is performed through the deconvolution layer, and the features of the same resolution in the encoder are fused with the features in the decoder with the help of jump connections. This feature fusion strategy not only retains the detail information, but also enhances the accuracy of feature positioning, greatly improving the accuracy of the segmentation results.
[0057] (3) Intelligent identification system test
[0058] 1) Model training
[0059] The dataset was randomly divided into training set, validation set and test set in a ratio of 8:1:1 for model training, validation and testing. The initial learning rate of training was set to 1×10 -4, the training batch size is set to 20, and the total number of training rounds is set to 200 epochs. In order to understand the training progress of the model, the model is evaluated during the training process, and the evaluation frequency is once every 5 epochs. In order to enable the model to dynamically adjust the learning rate according to the historical gradient of each parameter, the Adam optimizer is used. In order to improve the performance of the model, the pre-trained weights of the VGG network are used during the model training process. In order to prevent the imbalance of positive and negative samples, the Focal Loss loss function is used.
[0060] 2) Evaluation parameters
[0061] Mean Pixel Accuracy (mPA) and mean Intersection over Union (mIoU) were selected as the evaluation criteria for the intelligent identification method of infrared local warming of rock damage.
[0062] Pixel Accuracy (PA) refers to the proportion of pixels correctly classified by the model in the segmentation task to the total pixels. Mean pixel accuracy (mPA) is the average value of the pixel accuracy of each category, which can provide a more comprehensive evaluation of the model performance. The calculation formula (Formula 1) is as follows:
[0063]
[0064] Among them, TP (True Positive) is the number of pixels correctly classified as the target category; TN (True Negative) is the number of pixels correctly classified as the non-target category; FP (False Positive) is the number of pixels incorrectly classified as the target category; FN (False Negative) is the number of pixels incorrectly classified as the non-target category; i is a specific category; N is the number of categories.
[0065] The intersection over union (IoU) indicates the degree of overlap between the predicted area and the true area. The mean intersection over union (mIoU) is calculated by averaging the IoU of each category to provide an overall performance evaluation. The calculation formula (Formula 2) is as follows:
[0066]
[0067] 3) Recognition effect
[0068] The trained model is used to identify the local temperature increase areas in the infrared thermal images of rock damage. Some of the recognition results are as follows: Figure 4 As shown in the figure, the model has a good recognition effect on the local warming area of the thermal image.
[0069] Analyzing the training effect from the loss function value, the training set loss function value Train loss and the validation set loss function value Val loss both decrease as the number of epochs increases ( Figure 5 ), and finally flattens out and converges, which indicates the effectiveness of the training.
[0070] The experimental results are analyzed from the two indicators of mPA and mIoU. Both mPA and mIoU increase with the increase of epoch times and finally reach a stable value ( Figure 6 ), which shows the effectiveness of the model.
[0071] The various parameters of the experiment are shown in Table 1. Combined with the above analysis, it can be concluded that the intelligent identification system has excellent effect on the rock infrared local warming data set, with an mPA value of 94.37% and an mIoU value of 89.21%, which shows that the intelligent identification system can effectively identify the rock infrared local warming area.

[0073]
[0074] 2. Landslide Identification and Early Warning System
[0075] like Figure 7 As shown in the figure, the landslide body identification and early warning system is mainly used for remote non-contact identification of slope landslide bodies and landslide early warning. The system includes three modules, namely, IR acquisition warming extraction layer, IR local warming identification layer, and landslide comprehensive analysis and early warning layer.
[0076] IR acquisition warming extraction layer: Use satellite far-field monitoring or drone near-field monitoring of slopes to collect infrared thermal images. The original infrared thermal images may contain a lot of environmental interference information (such as pedestrians, buildings, forests, water bodies, etc.). The heat changes in these non-slope areas will interfere with the identification of landslides. Therefore, it is necessary to clean the collected infrared thermal images and delineate the slope area.
[0077] IR local warming identification layer: The processed data is input into the infrared local warming intelligent identification model. The infrared local warming intelligent identification model is a deep learning image segmentation model built based on U-Net. The trained and optimized intelligent identification model can effectively identify the warming area in the infrared thermal image.
[0078] Landslide comprehensive analysis and early warning layer: The infrared local warming intelligent identification model outputs infrared thermal images of the identified local warming areas. The warming area usually corresponds to the active area of the landslide body, because the landslide process is often accompanied by soil friction and pressure changes, resulting in local temperature increases. Through the infrared local warming intelligent identification model, the system can accurately identify the location and range of the landslide body. Integrate geological, meteorological and other data for risk assessment, and use the early warning system to determine whether there is a potential risk of landslides, and issue landslide warning signals in a timely manner.
[0079] The constructed landslide identification and early warning system is used to identify thermal images of slopes. Figure 8 As shown in the figure. It is not difficult to see from the recognition effect that the infrared warming intelligent identification system based on the U-Net deep learning network model built by the present invention has high recognition accuracy and successfully identifies the local warming area in the infrared thermal image. Combined with high-definition photos, after finding the slope, the slope landslide body can be successfully delineated.
[0080] In summary, by using the rock infrared local warming intelligent identification model based on the U-Net deep learning network, we carried out application research on remote non-contact identification of slope landslides, built a landslide identification and early warning system, and realized remote non-contact identification of landslides with good identification effect.
