When problems are discovered, it has become very difficult to investigate and deal with them. Manual inspection methods are backward and cannot timely discover, stop and investigate problems, which will lead to the escalation of the situation and have a significant impact on flood control safety and ecological protection in the basin, increasing the difficulty of water administration law enforcement. How to fully record the spatial characteristics and time series changes of river monitoring objects and the attribute changes throughout the life cycle, timely discover and deal with water-related illegal information in the river, prevent the situation from escalating, and strengthen the dynamic supervision of river law enforcement monitoring object information has become an urgent problem to be solved.

[0026] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined and referenced with each other under the premise of no contradiction.

[0027] An embodiment of the present application proposes a dynamic management system for the entire life cycle of spatiotemporal data of water administrative law enforcement. The implementation details of the dynamic management system for the entire life cycle of spatiotemporal data of water administrative law enforcement proposed in this embodiment are described in detail below. The following content is only the implementation details provided for the convenience of understanding and is not necessary for the implementation of this solution.

[0028] The specific structure of a dynamic management system for the full life cycle of spatiotemporal data of water administration law enforcement proposed in this embodiment can be as follows: Figure 1 As shown, its working principle can be Figure 2 As shown, the present embodiment proposes a dynamic management system for the entire life cycle of spatiotemporal data of water administration law enforcement, including: an warehousing module 101, an identification module 102, a dynamic tracking module 103, an extinction module 104 and a full-cycle tracing module 105.

[0029] The storage module 101 is used to read the input remote sensing image file. The attribute information of the input remote sensing image file needs to include the image number, image name, image shooting date, image type, image location description and storage time.

[0030] The identification module 102 is used to interpret the information of the stored remote sensing image files, identify the water administration law enforcement objects within the management scope, form suspected spots of each water administration law enforcement object, and generate water administration law enforcement spatiotemporal data.

[0031] The dynamic tracking module 103 is used to monitor the changes of various water administrative law enforcement objects through multi-temporal remote sensing image files and on-site data, and record the spatial nodes and time nodes of the changes.

[0032] The extinction module 104 is used to display the rectification status of each water administrative law enforcement object and compare the water administrative law enforcement objects before and after the rectification. When the comparison finds that the water administrative law enforcement object does not exist or disappears after the rectification, the extinction time is recorded.

[0033] The full-cycle tracing module 105 is used to trace the entire life cycle of the first discovered water administration law enforcement object, including its generation, increase, decrease, extinction, and reappearance. At the same time, it updates and records the maximum target spatial range of the water administration law enforcement object during its existence in real time, and continuously tracks the water administration law enforcement objects that are subsequently generated within the said maximum target spatial range.

[0034] In one example, the identification module consists of an interpretation unit, a correction unit, a discrimination execution unit and an interpretation information base. The interpretation information base stores a table of first-discovered objects and a table of suspected object interpretation results. The table of first-discovered objects is used to record the first-discovered objects and their basic data attributes. The basic data attributes include but are not limited to the map object code, name, type, administrative division, regulatory unit, discovery time, spatial range, area and image number, etc. The table of suspected object interpretation results is used to record the basic data attributes, first-discovery mark attributes and historical change attributes of each water administrative law enforcement object. The first-discovery mark attributes include whether it is the first time to be discovered in the range and the number of the object first discovered. The historical change attributes include but are not limited to the change type (addition, expansion, reduction, type change, extinction), generation time, elimination time, elimination type (completely cleared, as expected), creation time and update time, etc.

[0035] Among them, the object code is the ID information in the database, and the identification module will establish a unique code, i.e., a key-value item, for each suspected spot. For the object name, if it is a known object name (such as flood control projects, ecological parks, amusement parks, etc.), the known object name is used directly. If it is not a flood control project, the object type name is used as the name. Specifically, the object name is obtained by associating the object's geographical location with the existing object name and information library table. The object type is one of the 22 types, and the 22 types are river regulation projects, wave breakwaters, water intake (drainage) projects, cross-river bridges, riverside roads, forests, ponds, enclosure farming, ecological parks and amusement parks, sand mining ships, sand mining sites, oil wells, well platforms, waste slag, river enclosure projects, production embankments, river-crossing pipelines, riverside factories (houses), brick kiln factories, docks, photovoltaic power plants, and river dams (rubber dams). The spatial range refers to the vector data of the suspected spot outline. The attribute of the administrative division is obtained by comparing and associating with the administrative division vector map based on the geographical location and spatial scope of the water administrative law enforcement object. The attribute of the supervision unit is obtained by comparing with the supervision scope of the water administrative law enforcement unit based on the geographical location and coverage of the water administrative law enforcement object. The discovery time / first discovery time is the time when the image is taken. The area is obtained by vector calculation based on the spatial scope of the suspected spot. Whether it is the first time to be discovered in this range, the attribute value is yes or no. If the current spot does not overlap with the spatial scope of the object in the first discovery object library, it is considered to be the first time to be discovered in this range, otherwise it is deemed not to be the first time to be discovered in this range. The first discovered object number, the attribute value is an object code in the first discovered object table.

[0036] The interpretation unit is used to interpret the information of the remote sensing image file using a semantic segmentation model based on a hierarchical Transformer, and obtain the interpretation results of the identified water administrative law enforcement objects. The interpretation results include the type and spatial range of the suspected patches of the identified water administrative law enforcement objects.

[0037] The correction unit is used to obtain the correction information of human experts through human-computer interaction, and to correct the interpretation results of the identified water administrative law enforcement objects based on the obtained correction information of the human experts.

[0038] The discrimination execution unit is used to compare the spatial range of the corrected suspected spots with the coverage of each water administrative law enforcement object in the first-found object table; if the spatial range of the corrected suspected spots does not overlap with the coverage of each water administrative law enforcement object in the first-found object table, the identified water administrative law enforcement object is determined as the first-found object and is newly added to the first-found object table and the suspected object interpretation result table; if the spatial range of the corrected suspected spots overlaps with the coverage of each water administrative law enforcement object in the first-found object table, the overlapping water administrative law enforcement object is determined to be the target water administrative law enforcement object, and the interpretation result of the identified water administrative law enforcement object is entered into the historical change attribute of the target water administrative law enforcement object in the suspected object interpretation result table.

[0039] In one example, the semantic segmentation model based on the hierarchical Transformer divides the remote sensing image file into image blocks, retains only the image blocks containing the river range that needs to be monitored, performs model inference operations on these image blocks one by one, and after obtaining the segmentation results, merges the segmentation results according to the previous block principle, and forms the segmentation results of the entire image after certain post-processing. The model structure of the semantic segmentation model based on the hierarchical Transformer can be as follows: Figure 3 shown.

[0040] The semantic segmentation model based on the hierarchical Transformer consists of an encoder and a decoder. The encoder adopts a hierarchical Transformer structure, which consists of an image block embedding layer, four sequentially connected Transformer layers and a feature fusion layer. The input of the first Transformer layer is the output of the image block embedding layer, the input of the second Transformer layer is the output of the first Transformer layer, the input of the third Transformer layer is the output of the second Transformer layer, the input of the fourth Transformer layer is the output of the third Transformer layer, the input of the feature fusion layer is the output of each Transformer layer, each Transformer layer contains N (such as N = 2) Transformer blocks, each Transformer block contains a multi-head self-attention block and a hybrid forward propagation network, and the decoder adopts a multi-layer perceptron.

[0041] The Transformer block uses a window with a width and height of 3, a stride of 2, and an edge padding of 2. The image is divided into blocks by sliding the window, and the local continuity around the image block is retained by overlapping, while achieving a multi-scale effect similar to that of a convolutional neural network. At the same time, a hybrid forward propagation network is used, that is, a 3×3 depth-separable convolution is introduced into the feedforward network to transmit position information. In this way, the traditional position encoding is abandoned, so there is no need to worry about the problem of precision loss caused by interpolation of position encoding when the training resolution and the test resolution are different.

[0042] The image block embedding layer is used to segment the input remote sensing image files into blocks, retaining only the image blocks within the river range that needs to be monitored, and input the retained image blocks into the first Transformer layer.

[0043] Each Transformer layer is used to extract features from its own input to obtain feature maps of different scales.

[0044] Let h and w be the height and width of the input of the first Transformer layer, respectively. The scales of the feature maps of different scales output by the four Transformer layers are: h / 4×w / 4×C1, h / 8×w / 8×C2, h / 16×w / 16×C3, h / 32×w / 32×C4. The values ​​of C1, C2, C3, and C4 can be 64, 128, 256, and 512, respectively.

[0045] The feature fusion layer is used to fuse the feature maps output by each Transformer layer. The feature maps whose resolution needs to be reduced are downsampled through 3×3 convolution operations, and the feature maps whose resolution needs to be increased are upsampled using DUpsampling to obtain fused feature maps. The structure of the feature fusion layer can be as follows: Figure 4 shown.

[0046] DUpsampling uses a learnable method to perform upsampling instead of traditional bilinear interpolation. First, feature map encoding is performed, and N 1×1 convolutions are applied to the input feature map to obtain a new encoded feature map, whose number of channels is N times that of the input feature map. Then, feature map decoding is performed to reshape the encoded feature map into an output feature map with twice the width and height, and the number of channels is reduced to 1 / 4 of the original. Finally, the result is output, and the decoded feature map is used as the output after upsampling.

[0047] The multi-layer perceptron is used to adjust the channels of the fused feature map to obtain the semantic segmentation results of the input remote sensing image file, that is, the interpretation results of the identified water administrative law enforcement objects.

[0048] The feature fusion layer unifies the number of channels of the feature maps of the four scales to C, and then superimposes the channel dimensions to obtain a feature map of scale h / 4×w / 4×C. The multi-layer perceptron adjusts the feature map of scale h / 4×w / 4×C to h / 4×w / 4×N. cls As the semantic segmentation result of the input remote sensing image file. cls is the number of categories to be semantically segmented.

[0049] The multi-layer perceptron consists of a layer of Conv2d and a layer of layer norm.

[0050] In one example, the image blocks can be divided into blocks by overlapping a certain ratio, such as 10%, and the block size is 512px×512px. The merging method of the segmentation result image blocks can be merged according to the position of each sub-block in the image block, and the interpretation result is obtained by weighted averaging the overlapping part. Let the distance between the pixel to be fused and the edge of the image block be m (the value range is [0,50]), and the number of overlapping pixels on a single edge is L (generally set to 51), then the weight alpha = (m+1) / L. Post-processing mainly includes corrosion, expansion and hole filling in image morphological processing.

[0051] In one example, when training a semantic segmentation model based on a hierarchical Transformer, the existing water administration law enforcement background remote sensing monitoring image data (visible light 0.5m resolution) and the background results data of river monitoring objects are annotated to generate training samples. For drone monitoring and interpretation, the manually annotated background data can be directly used as training samples to train the semantic segmentation model. For spectral satellite remote sensing monitoring and interpretation, download spectral satellite remote sensing images of the same period, downsample the background results data according to the resolution of the spectral satellite images, and directly map the interpretation labels of the background results to the spectral satellite images as labels for training the semantic segmentation model.

[0052] In one example, the correction unit visualizes the interpretation results in different colors to human experts through human-computer interaction. The human experts input their correction information based on the visualized interpretation results. The correction unit then corrects the interpretation results of the identified water administrative law enforcement objects based on the correction information obtained from the human experts.

[0053] In one example, the structure of the dynamic tracking module is as follows Figure 5 As shown, it is composed of an object change monitoring unit 1031, a change state analysis unit 1032 and an on-site inspection and tracking unit 1033.

[0054] The object change monitoring unit 1031 is used to compare and analyze the remote sensing images of the previous and next phases of the same geographical location, and input the remote sensing images of the previous and next phases into the change detection model based on the dual-branch Segformer and multi-scale attention, respectively, to obtain the change detection results output by the change detection model based on the dual-branch Segformer and multi-scale attention, and call the recognition module to interpret the remote sensing image in the later phase based on the change detection results, and obtain the interpretation results of the remote sensing image in the later phase. Among them, the change detection result is a binary image, and the point with a pixel value of 0 indicates no change, and the point with a pixel value of 1 indicates a change. The design of the object change monitoring unit effectively saves computing resources.

[0055] The change state analysis unit 1032 is used to perform a change state analysis on the water administrative law enforcement object based on the interpretation results of the remote sensing images of the previous and next phases, obtain and record the change state analysis results, and the attribute information of the change state analysis results includes generation time, change type, change time, creation time and update time.

[0056] The on-site inspection and tracking unit 1033 is used to use satellite positioning technology to capture and record the precise location and inspection path of water administration law enforcement personnel in real time, and provide the suspected spots, change detection feature maps and change state analysis results of the same water administration law enforcement object in the two phases before and after to the water administration law enforcement personnel, so that the water administration law enforcement personnel can conduct on-site investigation and confirm the change state of the water administration law enforcement object to correct the change state analysis results.

[0057] In an example, the model structure of the change detection model based on dual-branch Segformer and multi-scale attention can be as follows Figure 6As shown in the figure, the change detection model based on dual-branch Segformer and multi-scale attention consists of a dual-branch encoder and a decoder. The encoder consists of two Segformer networks with shared weights and a change information extraction module. Each Segformer network consists of an overlapping block merging layer, four sequentially connected Transformer layers and four CCNet attention modules. For each Segformer network, the input of the first Transformer layer is the output of the overlapping block merging layer, the input of the second Transformer layer is the output of the first Transformer layer, the input of the third Transformer layer is the output of the second Transformer layer, and the input of the fourth Transformer layer is the output of the third Transformer layer. The inputs of the four CCNet attention modules are the outputs of the four Transformer layers, respectively. Each Transformer layer contains N (such as N=2) Transformer blocks, and each Transformer block contains a multi-head self-attention block and a hybrid forward propagation network.

[0058] The remote sensing images of the previous and next phases are respectively input into two Segformer networks based on the double-branch Segformer and multi-scale attention change detection models.

[0059] The overlapping block merging layer is used to divide its own input into image blocks, retaining only the image blocks of the river range that needs to be monitored, and input the retained image blocks into the first Transformer layer.

[0060] Each Transformer layer is used to extract features from its own input to obtain semantic feature maps of different scales. The semantic feature maps of different scales output by the four Transformer layers can be recorded as and

[0061] The CCNet attention module is used to perform affinity operations and long-range context information aggregation operations on the input semantic feature map to obtain an enhanced semantic feature map. The enhanced semantic feature maps output by the four CCNet attention modules of the same Segformer network are concatenated and fused to obtain the final semantic feature map and input it into the change information extraction module.

[0062] by For example, After being input into the corresponding CCNet attention module, the CCNet attention module first Perform two 1×1 convolution operations to obtain the query vector Q and the key vector K respectively, and then obtain the attention map A through affinity operation. For each position u in Q, we can get a set Ω u , which comes from the eigenvalues ​​of K corresponding to the vertical and horizontal directions of the position u.

[0063] The affinity operation formula can be expressed as: where d iu It represents the characteristic Q u and By adding a softmax layer on d, we can get the final attention map A.

[0064] Then, in Performing a 1×1 convolution operation on the feature map V can get a vector V for each position u in V. u and a set Φ u , set Φ u is the set of eigenvectors in V that are located in the same row or column at position u.

[0065] Remote context information is collected by the aggregation operation and can be expressed as: It represents the feature vector of the output feature map H′ at position u, A i,u represents the scalar value at channel i, position u in the attention map A. Contextual information is added to the local feature H to enhance the local features and strengthen the pixel-wise representation, effectively extracting features.

[0066] The enhanced semantic feature maps output by the four CCNet attention modules of the same Segformer network are concatenated and fused to obtain the final semantic feature map. The outputs of the two Segformer networks are recorded as and

[0067] The change information extraction module is used to extract the final semantic feature maps output by the two Segformer networks. and Perform absolute difference operation to extract the change feature f cd , and extract the change feature f cd Input to the decoder.

[0068] The decoder is used to transform the input feature f cd Perform binary change detection, pass through a 3×3 convolution layer, and then pass through a 1×1 convolution layer to output the change detection feature map.

[0069] In one example, when iteratively training a change detection model based on dual-branch Segformer and multi-scale attention, the model training epoch is set to 100 and the batch size is set to 4. During the training process, AdamW is used as the optimizer with a weight decay coefficient of 0.0001. A polynomial learning rate schedule is used, with the initial learning rate for the encoder set to 1.5e-4 and the initial learning rate for the decoder set to 1.5e-3, which is 10 times that of the encoder.

[0070] In one example, the image can be divided into blocks by overlapping a certain ratio, such as 10%, and the block size is 512px×512px. The method for merging the interpretation results of the image blocks is to merge them according to the positions of each sub-block in the image block, and the interpretation results are obtained by weighted averaging for the overlapping parts. Let the distance between the pixel to be fused and the edge of the image block be m (the value range is [0,50]), and the number of overlapping pixels on a single edge is L (generally set to 51), then the weight alpha = (m+1) / L. Post-processing mainly includes erosion, expansion and hole filling in image morphological processing.

[0071] In one example, the generation time is the time when the remote sensing image is generated. The change time is the time after the object type change is confirmed. The creation time is the interpretation time of the water administration law enforcement object. The update time is the time when the attribute information of the water administration law enforcement object is filled in, and it is updated in real time as the information is filled in.

[0072] In one example, the change type of the change state analysis result is classified into addition, expansion, reduction, elimination, type change, etc., as follows:

[0073] 1) First, check whether the object discovered this time is within the coverage of the first discovered object. If not, it is a new type (such as Figure 7 As shown in the first row), mark it as the first discovered object, enter the first discovered object table, and supplement the object code, name, type, administrative region, regulatory unit, discovery time, area and other information.

[0074] 2) If yes, it is necessary to subdivide and select the most recently discovered object associated with the first discovered object for spatial range comparison and judgment. Figure 7 If the spatial scope is larger than the last discovered object, it is marked as an expanded type, and after supplementing with monitoring images, discovery time, first discovered object number and other information, it is entered into the suspected object interpretation results table.

[0075] 3) If there is a shrinkage phenomenon (such as Figure 7 If the suspected object is not found, it is marked as a narrowed type and after supplementing the information, it is entered into the suspected object interpretation results table.

[0076] 4) If there is a type change phenomenon, that is, the object types of the two phases are different, such as from pond farming to photovoltaic power plants (such as Figure 7 If the type of the suspected object is changed, it is marked as a type change type, and after supplementing the information, it is entered into the suspected object interpretation result table.

[0077] 5) Detection of objects that are not within the above scope and have not been eliminated recently (such as Figure 7 As shown in the 5th row), this time it is marked as an elimination type in the form of a dot, and after supplementing the information, it is entered into the suspected object interpretation result table.

[0078] In one example, the on-site inspection tracking module uses satellite positioning technology to capture and record the precise location and inspection path of water administration law enforcement personnel in real time, and displays the interpretation results to be determined on the satellite image, such as Figure 8 As shown, it is provided to water administration law enforcement personnel for status determination. The results of water administration law enforcement object change monitoring are combined with on-site inspection tracking. After the change monitoring results are extracted, water administration law enforcement personnel will confirm and mark the object change type based on the actual business object and on-site investigation on the computer or mobile phone. Finally, if the law enforcement object is confirmed to be newly added, expanded, or converted in type, the water administration law enforcement personnel will carry out on-site law enforcement with the mobile phone app until the object is eliminated or it is determined that the expected goal has been achieved, and it will be marked in the form of a point.

[0079] In one example, the extinction module is implemented and used by the superior water administration regulatory department. It is mainly responsible for displaying the rectification status of each water administration law enforcement object, the comparison before and after the rectification, and the historical suspected spots of each water administration law enforcement object. It feedbacks the water administration law enforcement results based on the comparison before and after the rectification, evaluates whether the water administration law enforcement effect has achieved the expected goals, and accepts and confirms the extinction of water administration law enforcement objects that have achieved the expected goals, no longer exist or disappeared after rectification. The extinction time is recorded in the suspected object interpretation results library. Otherwise, it is returned to the grassroots water administration law enforcement unit for further rectification. Fig. 9 A comparison before and after rectification is shown.

[0080] In one example, the full-cycle tracing module supports the retrieval of first-discovered objects for the first-discovered object codes input by users, queries the detailed information of the retrieved first-discovered objects in the interpretation information library, traces the entire life cycle of the retrieved first-discovered objects, including generation, increase, decrease, extinction, and reappearance, sorts all the collected information in chronological order, cleans and formats it, and displays it to users through timelines, maps, status change lists, and interactive charts. In other words, it performs four functions: data retrieval and integration, status change sorting, data preprocessing, and multi-mode display.

[0081] In one example, the timeline display uses a timeline to show the entire life cycle of a water administrative law enforcement object. The timeline marks each key time point, including the first discovery time, change time, extinction time, and reappearance time, and supports users to view the corresponding detailed information by clicking on the key time points on the timeline.

[0082] The map display shows the spatial position changes of water administrative law enforcement objects on the map, uses different colors (such as green for generation, red for disappearance, yellow for reappearance, etc.) or icons to indicate the different states of water administrative law enforcement objects, and dynamically updates the display on the map as the timeline moves. For the maximum spatial range, a transparent polygonal area or circular area is marked on the map, and it is dynamically adjusted as the data is updated.

[0083] The state change list display provides a list view that lists the detailed information of all state change events, and supports users to view and operate by clicking the list items in the list view to expand or collapse the detailed information.

[0084] Interactive chart display uses interactive charts (such as bar charts, line charts, etc.) to display the trend and statistical information of the status changes of water administrative law enforcement objects, including the increase and decrease trends of water administrative law enforcement objects and the distribution of different status types. Users can view more detailed data point information or filter charts through mouse interaction (such as hovering, clicking).

[0085] In this embodiment, a dynamic management system for the full life cycle of water administration law enforcement spatiotemporal data, which is composed of a warehousing module, an identification module, a dynamic tracking module, an extinction module and a full-cycle tracing module, is constructed and operated. This enables full-process, all-round, full-cycle and blind-spot dynamic management of water administration law enforcement objects with multi-temporal, multi-spatial scales, multi-dimensional business attributes and relationships, which effectively solves the current problems of insufficient flexibility and pertinence in the traceability of water administration law enforcement objects, facilitates better correlation analysis of data between different time phases, and provides direct evidence support and disposal suggestions for the decision-making of water administration law enforcement departments.
