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 making creative efforts are within the scope of protection of the present invention.
[0063] In order to solve the problem that the existing patent data acquisition channels are relatively complex and anomalies in the database cannot be discovered in time, affecting the integrity and reliability of the data, please refer to Figure 1-Figure 2 , this embodiment provides the following technical solutions:
[0064] A method for constructing a monitoring database for ecological restoration includes the following steps:
[0065] Step 1: Collect historical data on mine ecological restoration monitoring and remote sensing images of mine ecological restoration;

[0068] Step 4: Associate the classified real-time monitoring data of mine ecological restoration with the data in the monitoring database and establish a monitoring database update mechanism;
[0069] Step 5: Monitor the data in the monitoring database in real time and monitor the intrusion behavior in the monitoring database in real time, and issue an early warning signal when there is an abnormality in the data in the monitoring database.
[0070] Based on the historical data of ecological restoration in mining areas, multiple sub-databases of different types of data are established, and a monitoring database is obtained based on the sub-databases of different types of data, including:
[0071] Classify historical data on ecological restoration in mining areas and establish multiple sub-databases of different types of monitoring data based on the classification results;
[0072] Assigning index hierarchical identifiers corresponding to different types of monitoring data to sub-databases of different types of data, where the index hierarchical identifiers are obtained by mixing at least two of the spatiotemporal index, inverted index, and multi-level index;
[0073] According to the index hierarchical identification, multiple groups of different types of monitoring data are hierarchically stored to obtain a monitoring database.
[0074] Processing of remote sensing images and ground feature identification for mine ecological restoration, including:

[0077] Input the remote sensing image of the mine ecological restoration area to be identified into the mine ecological restoration area feature identification model to obtain the feature identification result;
[0078] By identifying the features of mine ecological restoration through the mine ecological restoration area feature identification model, we can timely understand the progress and effect of mine restoration, provide a scientific basis for restoration work, help determine the key areas and methods of restoration, thereby optimizing the restoration plan and improving restoration efficiency. It can more accurately assess the difficulty and cost of restoration work, provide a basis for decision-making, analyze the changes in mine features, timely discover and solve problems, and improve management efficiency. At the same time, by directly identifying features on mine ecological restoration remote sensing images, relevant data of mine ecological restoration can be obtained. Remote sensing images can cover a large range of surface areas, realize comprehensive and rapid monitoring of mine environment, and significantly improve monitoring efficiency. Feature identification is based on objective data and information, avoiding interference and errors caused by human factors, and can more accurately evaluate the effect and progress of mine ecological restoration. By comparing remote sensing images of different time periods, dynamic monitoring of mine restoration can be achieved, and changes in mine environment over time can be observed and analyzed, providing scientific guidance for subsequent restoration work. Data acquisition is more efficient and convenient, and the cost is low, which can greatly save manpower, material and time costs.
[0079] Specifically, the image enhancement processing of the remote sensing image of the mine ecological restoration area specifically includes:
[0080] Extracting remote sensing images of the mine ecological restoration area;
[0081] The Canny edge detection algorithm is used to obtain the edge image area of the remote sensing image of the mine ecological restoration area;
[0082] Extracting the grayscale values corresponding to the pixels contained in the edge image area;
[0083] Obtaining a grayscale coefficient using grayscale values corresponding to pixels contained in the edge image area;
[0084] The grayscale coefficient is obtained by the following formula:
[0085]
[0086] Among them, Y represents the grayscale coefficient; n represents the number of pixels contained in the edge image area; S i Indicates the grayscale value corresponding to the i-th pixel in the edge image area; S p Represents the grayscale average value corresponding to n pixels in the edge image area; S max and S min Indicates the maximum and minimum grayscale values corresponding to n pixels in the edge image area; S fz Represents the central grayscale value of the non-edge image area;
[0087] comparing the gamma coefficient with a preset gamma coefficient threshold;
[0088] When the gamma coefficient exceeds a preset gamma coefficient threshold, the brightness of the edge image area is adjusted.
[0089] The technical solution described above achieves the following: By employing the Canny edge detection algorithm, it can accurately extract edge image regions from remote sensing images of mine ecological restoration areas. The Canny algorithm is a multi-stage edge detection algorithm with low false positive and false negative rates. It effectively identifies edge information in images, providing an accurate basis for subsequent processing. Grayscale values of pixels in edge image regions are extracted, and the gamma coefficient is calculated based on these values, enabling quantitative analysis of the image's grayscale characteristics. This step provides a deeper understanding of the image's grayscale distribution characteristics, providing a basis for subsequent judgment and processing. By comparing the calculated gamma coefficient with a preset gamma coefficient threshold, it is determined whether brightness adjustment is required in edge image regions. If the gamma coefficient exceeds the threshold, it indicates that the brightness of the edge region may be too high or too low, requiring adjustment to improve image visualization. This adaptive brightness adjustment method helps maintain overall image brightness and contrast, improving image quality. By adjusting the brightness of edge image regions, the visual quality of the image can be further improved, making the features of the mine ecological restoration area more distinct. This helps improve the accuracy of image recognition and analysis, providing strong support for subsequent mine ecological restoration efforts. By extracting and analyzing edge information and grayscale features from remote sensing images, this technical solution provides more objective and accurate data support for mine ecological restoration. This data can help decision-makers better understand the actual conditions in mine ecological restoration areas, leading to more scientific and reasonable restoration plans.
[0090] In summary, this technical solution improves the recognition and analysis accuracy of remote sensing images in mine ecological restoration areas through precise edge detection, quantitative analysis of grayscale features, and adaptive brightness adjustment, providing strong technical support for mine ecological restoration work.
[0091] Specifically, when the gamma coefficient exceeds a preset gamma coefficient threshold, the brightness of the edge image area is adjusted, which specifically includes:
[0092] When the grayscale coefficient does not exceed a preset grayscale coefficient threshold, retrieving a non-edge image area of a remote sensing image of a mine ecological restoration area;
[0093] Extracting the grayscale values of the pixels contained in the non-edge image area of the remote sensing image of the mine ecological restoration area;
[0094] Obtaining a brightness adjustment coefficient using the grayscale values corresponding to the pixels included in the edge image area and the grayscale values of the pixels included in the non-edge image area;
[0095] The brightness adjustment coefficient is obtained by the following formula:
[0096]
[0097] Where r represents the brightness adjustment coefficient; n represents the number of pixels contained in the edge image area; m represents the number of pixels contained in the non-edge image area; S i Indicates the grayscale value corresponding to the i-th pixel in the edge image area; S j Indicates the grayscale value corresponding to the jth pixel in the non-edge image area; Y represents the grayscale coefficient; S fz Represents the central grayscale value of the non-edge image area; S yz表示 The center gray value of the edge image area; S fmax Indicates the maximum grayscale value of the non-edge image area;
[0098] The brightness of the edge image area is adjusted using the brightness adjustment coefficient, and the brightness value after brightness adjustment is obtained by the following formula:
[0099]
[0100] Wherein, L represents the brightness value after brightness adjustment; L0 represents the brightness value before brightness adjustment; r represents the brightness adjustment coefficient; and Y represents the grayscale coefficient.
[0101] The technical effect of the above-mentioned technical solution is that, when the gamma coefficient does not exceed the preset threshold, the solution not only considers the grayscale characteristics of the edge image area but also incorporates the grayscale information of the non-edge image area. By calculating the brightness adjustment coefficient, adaptive adjustment of the brightness of the edge image area is achieved. This adjustment method can more precisely handle brightness differences in the image, avoiding over-adjustment or under-adjustment. By incorporating the grayscale information of the non-edge image area, the solution can more comprehensively understand the grayscale distribution of the entire remote sensing image. This helps maintain the overall consistency and naturalness of the image when adjusting the brightness of the edge image area. The adjusted image improves brightness, contrast, and clarity, thereby enhancing the visual quality and readability. Edge image areas often contain important feature information, such as terrain changes and vegetation distribution. By adjusting the brightness of edge image areas, their features can be more distinct, thereby enhancing image recognition. This is of great significance for subsequent monitoring, assessment, and planning of mine ecological restoration. The brightness adjustment coefficient calculation formula in the solution comprehensively considers the grayscale information of both edge and non-edge image areas, as well as the influence of the gamma coefficient. This makes the processing process more scientific and rational, and facilitates automation and intelligent implementation. Remote sensing images after brightness adjustment can more accurately reflect the actual conditions in the mine ecological restoration area, providing more reliable data support for decision makers. This helps decision makers develop more scientific and reasonable restoration plans, improving restoration effectiveness and efficiency. Compared to traditional manual brightness adjustment methods, this solution automatically adjusts brightness by calculating a brightness adjustment coefficient. This significantly reduces the need for manual intervention and improves processing efficiency and accuracy.

[0107] The data processing module is used to obtain real-time remote sensing images of mine ecological restoration and historical data of mine ecological restoration monitoring, and preprocess, geometrically correct and enhance the remote sensing images of the mine ecological restoration area. Among them, preprocessing includes: eliminating or reducing periodic noise to ensure image quality, reducing thin clouds that appear on remote sensing images due to weather reasons, improving image clarity, using the ratio method to eliminate mountain shadows caused by the solar altitude angle, and ensuring the accuracy of image information. Geometric correction includes: aligning the geographic coordinates of different data sources for overlay display and mathematical calculations, correcting through image-to-image, image-to-map or image-to-known coordinate points to ensure that remote sensing data is accurately located in a specific geographic coordinate system, using geographic reference data and digital elevation model data to correct the original remote sensing images and eliminate image deformation caused by terrain undulations. Image enhancement includes: using color synthesis methods to process multispectral images to obtain color images, improve the readability of ground feature information, adjust the histogram to a normal distribution, improve image quality, enhance contrast, and classify grayscale images and assign different colors to convert the original grayscale images into pseudo-color images.
[0108] Preprocessing can remove noise and interference information in remote sensing images, improve image clarity and accuracy, and provide a reliable data basis for subsequent analysis and evaluation. Geometric correction can correct the geometric distortion caused by sensor position, angle and other factors during the acquisition of remote sensing images, ensure that the spatial information in the image is consistent with the actual situation, and improve the accuracy of spatial positioning. Image enhancement processing adjusts the image contrast, brightness, color and other parameters to make the key features in the image more prominent, which facilitates the identification and extraction of relevant information in the mine ecological restoration area, such as vegetation recovery and soil quality changes. Remote sensing images that have undergone preprocessing, geometric correction and image enhancement can be analyzed and interpreted more quickly, improving the efficiency and accuracy of mine ecological restoration effect evaluation, and providing strong support for the planning, implementation and monitoring of restoration work.

Remote sensing images can be used to assess the extent of land damage caused by mining, such as land exposure and soil erosion. At the same time, by comparing remote sensing images before and after restoration, the effectiveness of restoration work, including land reclamation and vegetation reconstruction, can be quantitatively evaluated.
