[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] This application uses multi-source data fusion to perform pixel-based allocation of plot biomass and combines different vegetation types to perform carbon storage conversion, thus constructing a complete and more refined method for estimating aboveground carbon storage.

[0027] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] The aboveground vegetation carbon storage inversion method provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, terminal 101 communicates with server 102 via a network. A data storage system can store the data that server 102 needs to process. The data storage system can be set up independently, integrated into server 102, or placed in the cloud or on another server. Terminal 101 can send hyperspectral images of the study area to server 102, and server 102 can retrieve the aboveground vegetation carbon storage of the study area based on the received hyperspectral images. Server 102 can then feed back the aboveground vegetation carbon storage of the study area to terminal 101.

[0029] The terminal 101 can be, but is not limited to, various desktop computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, and smart in-vehicle devices. Portable wearable devices can include smartwatches, smart bracelets, and head-mounted devices. The server 102 can be implemented using a standalone server or a server cluster composed of multiple servers, or it can be a cloud server.

[0030] In one exemplary embodiment, such as Figure 2 As shown, a method for inverting aboveground vegetation carbon storage is provided. This method is executed by computer equipment, specifically by a terminal or server alone, or by both a terminal and a server. In this embodiment, the method is applied to... Figure 1 Taking server 102 as an example, the explanation includes the following steps 201 to 205.

[0031] Step 201: Obtain hyperspectral images of the study area.

[0032] In a specific application example, a high spatial resolution hyperspectral image covering the study area was acquired using a hyperspectral imaging system mounted on a drone, providing rich spectral information for subsequent feature extraction and classification.

[0033] The hyperspectral image is then further subjected to Gaussian filtering and noise band removal processes.

[0034] Step 202: Classify each pixel in the hyperspectral image using a pre-trained classification model to determine the vegetation type of each pixel. The classification model is a random forest model.

[0035] Specifically, a random forest model is used to perform refined vegetation classification on the hyperspectral images of the study area, outputting distribution patches of dominant tree species or vegetation types within the study area (including the vegetation type of each pixel). These distribution patches are used for subsequent determination of carbon storage coefficients, which can improve the ecological significance and accuracy of carbon storage estimation.

[0036] Step 203: Extract features from the hyperspectral image to determine the remote sensing features of each pixel.

[0037] Step 204: Based on the remote sensing characteristics of each pixel, the biomass in the study area is inverted using an inversion model to obtain the biomass of each pixel.

[0038] The inversion model is pre-trained using a training sample set, which includes remote sensing features of each pixel within multiple sample plots and the actual biomass of each pixel. The actual biomass is determined based on hyperspectral imagery and three-dimensional structural parameters of the sample plots.

[0039] In a specific application example, the training process of the inversion model includes the following steps (1) to (6).

[0040] (1) Obtain hyperspectral images, multi-view images and sample plot survey data from multiple sample plots.

[0041] Specifically, hyperspectral images of the sample plots were collected using a hyperspectral imaging system mounted on a drone. At the same time, multi-view images were collected using an oblique photography system on the drone, providing accurate monitoring data for subsequent 3D reconstruction to obtain digital surface models (DSMs) and 3D structural parameters such as canopy surface area.

[0042] In addition, data collected from ground-based sample plot surveys, including tree species type, diameter at breast height (DBH), and height, were used. Individual tree biomass was calculated based on DBH and height, and the total biomass within the sample plots was tallied based on the individual tree biomass, providing necessary real-world sample support for subsequent inversion model construction.

[0043] (2) For any sample site, the hyperspectral image, multi-view image and sample site survey data of the sample site are spatially calibrated.

[0044] First, the hyperspectral images were sequentially processed with Gaussian filtering and noise band removal. Then, the hyperspectral images, multi-view images, and sample plot survey data were spatially calibrated to ensure that data from different sources could be uniformly projected onto the same coordinate system, laying the foundation for subsequent analysis.

[0045] (3) Calculate the vegetation index of each pixel in the plot based on the calibrated hyperspectral image, and calculate the canopy surface area of ​​each pixel in the plot based on the calibrated multi-view image.

[0046] Specifically, a digital surface model is generated based on the calibrated multi-view images. The digital surface model includes an elevation grid for each pixel and the dimensions of each pixel, i.e., three-dimensional structural parameters. The slope of each elevation grid in the digital surface model is calculated and converted into radians to obtain the radian value of each pixel. Calculate the canopy surface area of ​​each pixel based on its curvature and size: .in, For the first in the digital surface model k Line number j The radians of the corresponding pixels in the elevation raster. For the first in the digital surface modelk Line number j The slope of the elevation grid. For the first in the digital surface model k Line number j The canopy surface area of ​​the corresponding pixels in the column elevation raster. The size of the pixel.

[0047] (4) Calculate the actual biomass of each pixel in the sample plot based on the vegetation index, canopy surface area of ​​each pixel and sample plot survey data.

[0048] The following formula is used to calculate the first... i The actual biomass of a single pixel:

[0049] ;

[0050] in, For the first i The true biomass of a single pixel For the first i The canopy surface area of ​​each pixel For the first i The vegetation index of each pixel This represents the total biomass within the sample plot.

[0051] In view of the inconsistency between the plot scale and the image pixel scale in traditional biomass inversion, this application calculates the vegetation index and canopy surface area of ​​each pixel in the plot, and then weights the total biomass of the plot according to the proportion of vegetation index and structural features (canopy surface area) within the pixel. This realizes the mapping of the measured biomass of the plot to the pixel scale, generates pixel-level real biomass, and provides accurate labeled data for subsequent model training.

[0052] (5) Extract features from the calibrated hyperspectral image to obtain the remote sensing features of each pixel in the sample plot.

[0053] Specifically, spectral and textural features of pixels within the sample plots are extracted from hyperspectral imagery. Then, based on the importance of each feature to biomass, all features are selected, and the top 50 features are retained as remote sensing features for model construction to improve computational efficiency and enhance model stability.

[0054] The feature selection process involves training a random forest regression model using all features. The random forest regression model, through an ensemble learning mechanism of multiple decision trees, automatically evaluates the contribution of each feature to the predicted target variable (e.g., biomass) during training. Then, the importance of each feature is calculated. During model training, the random forest quantifies the contribution of each feature to improving predictive performance based on the reduction in the Gini index or the decrease in the mean squared error at node splits. A higher index indicates a stronger explanatory power for the target variable. Finally, all features are sorted from highest to lowest according to their contribution scores, forming a complete list of feature importance. This list reflects the degree of influence of each feature relative to the overall model in predicting biomass.

[0055] (6) Construct a training sample set based on the actual biomass of each pixel in each sample plot and the remote sensing features of each pixel, and use the training sample set to train the inversion model.

[0056] Furthermore, this application can construct various inversion models based on the selected remote sensing features and actual biomass, including multiple linear regression, random forest, XGBoost, LightGBM, support vector regression, and artificial neural networks. The performance of each model is comprehensively evaluated through cross-validation and accuracy metrics, and the optimal model is selected for aboveground biomass inversion in the study area, outputting biomass results. The model ultimately selected in this application is the random forest model.

[0057] To address the challenges of accurately mapping biomass samples from sample plots to remote sensing pixels and the differences in carbon conversion coefficients among different vegetation types, this application utilizes hyperspectral imagery and three-dimensional structural data (such as canopy surface area) acquired by unmanned aerial vehicles (UAVs) to perform refined spatial allocation of biomass within sample plots at the pixel scale, achieving precise mapping of biomass samples to the pixel level. Based on this, an inversion model is constructed by combining multi-source remote sensing features, and carbon conversion coefficients for different vegetation types are determined using vegetation classification patches, ultimately achieving a high-precision estimation of aboveground vegetation carbon storage. Compared to traditional uniform allocation methods based on sample plot mean, this application preserves the structural differences within sample plots, improves the consistency and representativeness of training samples, and thus significantly enhances the reliability and accuracy of remote sensing inversion results.

[0058] Step 205: Determine the aboveground vegetation carbon storage in the study area based on the carbon conversion coefficient of each vegetation type, the vegetation type of each pixel, and the biomass of each pixel.

[0059] In a specific application example, for any given pixel, the carbon conversion coefficient of that pixel is determined based on its vegetation type. The carbon storage of that pixel is calculated based on its carbon conversion coefficient and biomass. The carbon storage is the product of the carbon conversion coefficient and biomass. The aboveground vegetation carbon storage of the study area is determined based on the carbon storage of each pixel. The aboveground vegetation carbon storage of the study area is the sum of the carbon storage of each pixel.

[0060] Specifically, based on the distribution patches of vegetation types obtained in step 202, the biomass inversion results are processed into blocks according to different vegetation types. Subsequently, based on the carbon conversion coefficients of various vegetation types, the aboveground vegetation carbon storage in the study area is calculated to form the final spatial data product of carbon storage, providing a scientific basis for regional ecological monitoring and carbon sink assessment.

[0061] This application significantly improves the accuracy and stability of aboveground biomass inversion by fusing hyperspectral imagery with three-dimensional structural parameters. The proposed plot biomass pixelation method effectively solves the problem of inconsistency between plot scale and pixel scale in traditional methods, making model training more accurate. In addition, the hierarchical inversion method based on vegetation classification makes the final biomass and carbon storage results more consistent with ecological characteristics, achieving high-precision and high-resolution biomass estimation.
