Description
Technical Field
[0001] The present invention relates to the technical field of terrain surveying and mapping, and more particularly, to a terrain surveying and mapping method and system based on artificial intelligence. Background Art
[0002] With the advent of photography technology, photogrammetry began to be used in topographic mapping. Through photos taken from the air or on the ground, three-dimensional models were created and topographic information was extracted. In the process of carrying out engineering construction, topographic mapping is the preliminary preparation work. The measurement and collection of relevant data of geographic space can make the relationship between buildings and nature more harmonious, and make the information of artificial buildings clearer in the process of standardizing the geographic space location. The spatial location is marked with numbers, names and distances, and the information of the construction project is clearly marked. The distance, place names and various attributes are divided so that the geographic space location can be clearly displayed on the topographic map, which is convenient for the implementation of engineering construction. At present, the traditional topographic mapping method has the following technical bottlenecks:
[0003] Low data fusion efficiency: The temporal and spatial benchmarks of multi-source sensor data are inconsistent, and traditional ICP registration is time-consuming and inaccurate.
[0004] Coarse feature extraction granularity: Networks such as U-Net have difficulty identifying sub-meter terrain features (such as ditches and cracks) due to the loss of feature map resolution (1 / 32);
[0005] Lack of dynamic prediction: Existing 3D reconstruction methods (such as oblique photography) lack physical constraints and cannot simulate the geomechanical evolution process;
[0006] Decision support lags: Traditional numerical simulation calculations are time-consuming and cannot meet real-time warning needs. Summary of the Invention
[0007] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a terrain mapping method and system based on artificial intelligence.
[0008] To achieve the above object, the present invention provides the following technical solutions:

In the task branch, semantic segmentation uses DeepLabv3+ to extract information such as water systems, vegetation, and artificial buildings. Instance segmentation uses Mask R-CNN to identify independent terrain units. Key point detection uses SuperPoint to locate feature markers. Slope calculation and curvature analysis are also performed on the data source.

[0016] Furthermore, the specific method for suppressing noise and enhancing data in step (1) includes constructing a noise-aware generative adversarial network, separating terrain signals from sensor noise through a spectral normalization discriminator, using the StyleGAN2-ADA algorithm to perform texture enhancement on low-quality areas, and improving the resolution of weak feature areas by more than 4 times. At the same time, a lightweight edge computing module is developed to fuse multi-source data streams in real time and output a standardized terrain feature tensor to support end-to-end feature transfer for subsequent terrain extraction tasks.
[0017] Furthermore, the HRNet+ high-resolution feature preservation in step (2) adopts an improved high-resolution network to maintain spatial accuracy through multi-resolution parallel processing and enhanced feature fusion.
[0018] Furthermore, the multi-resolution parallel processing constructs a resolution sequence of four branches for the input image size H×W, and the formula Compute the feature exchange performed at each stage, where It is a cross-resolution feature transformation operator, including 1×1 convolution and bilinear interpolation, i=1,2,3,4.
[0019] Furthermore, the enhanced feature fusion introduces the coordinate attention module (CA) to optimize feature selection. The processing result of the feature map by the coordinate attention module is expressed as follows: Calculated, where GAP is global average pooling, GMP is global maximum pooling, and σ is Sigmoid activation.
[0020] Furthermore, the specific method of 3D model reconstruction and optimization in step (3) is to adopt feature-enhanced NeRF modeling, fuse feature encoding with spatial coordinates, predict density and color through MLP, generate predicted images using differentiable rendering, jointly optimize reconstruction and feature consistency, and optimize the image quality based on geometric constraints and multi-viewing. Figure 1 Consistency, iteratively optimize model details, at the same time, prune low-density areas, reduce floating noise, convert the point cloud output by NeRF into an explicit mesh, fill in missing patches, force the optical flow of adjacent perspective rendering results to be consistent with the real offset, and introduce a discriminator network to distinguish high-frequency details between real and rendered images.
[0021] Furthermore, the dynamic terrain evolution modeling in step (4) specifically includes using a spatiotemporal tensor data structure and a Transformer architecture to process historical and real-time data, capturing terrain changes at different time scales, combining numerical simulation and a data-driven dual-branch network, ensuring that the prediction complies with physical laws through a differentiable physical layer, utilizing multi-agent simulation and graph neural networks to process the interaction of factors such as erosion and sedimentation, using GAN for multi-resolution prediction, and updating the model through online learning, and developing a visualization platform to support multiple simulations and real-time adjustments.
[0022] Furthermore, an artificial intelligence-based terrain mapping system is provided for implementing an artificial intelligence-based terrain mapping method, the system comprising:

[0029] In summary, this application includes at least one of the following beneficial technical effects:
[0030] This method breaks through the limitations of traditional single data sources through cross-modal intelligent registration and noise suppression mechanisms. At the same time, the spatial-spectral joint registration framework based on deep features effectively overcomes the temporal and spatial reference differences and sensor noise interference of multi-source data, significantly improving data consistency in complex terrain. The dynamic adaptive enhancement of this method uses spectral domain filtering and texture reconstruction technology of generative adversarial networks to achieve autonomous optimization of data quality. It is particularly suitable for feature recovery in harsh acquisition environments such as cloud obscuration and multiple echoes. The system achieves holographic analysis of terrain elements through a multi-task collaborative deep learning architecture. The advanced HRNet+ backbone network retains sub-meter terrain details (such as water tributaries and engineering structure joints) to the greatest extent through multi-scale parallel convolution and feature reconstruction mechanisms, overcoming the problem of small target information loss caused by downsampling in traditional networks.
[0031] This system implements a physics-data-driven approach, embedding terrain parameter calculations (slope / curvature) into the feature extraction process. This system enhances the model's geoscientific interpretability through physical prior constraints, improving the reliability of identifying steeply changing regions and complex geometric structures. Through the gradient interaction between the numerical simulation branch and the data-driven branch, a deep fusion of physical laws and observational data is achieved, ensuring that predictions are both consistent with geomechanical principles and adaptable to complex environmental evolution. Furthermore, the model update architecture, based on incremental learning, dynamically integrates new sensor data and field monitoring feedback, continuously improving the system's generalization performance in unknown terrain scenarios.
