The core content of this technical field is to obtain the target information and specific features contained in the image through operations such as decoding, feature extraction, classification, segmentation and enhancement of remote sensing images, so as to achieve comprehensive perception and analysis of surface information. Remote sensing image processing technology as a whole covers aspects such as image data preprocessing, geometric correction, spectral analysis and automatic analysis of image content, involving a complete technical chain from data acquisition, storage, transmission to subsequent in-depth analysis and application development.

[0003] Among them, remote sensing image processing methods refer to the processing and analysis of acquired remote sensing image data through specific image analysis and calculation methods to extract target information from it. This method focuses on technical matters such as geometric distortion correction, spectral feature analysis, and accurate extraction of spatial information of remote sensing images. It mainly uses target recognition technology based on deep learning, regional segmentation algorithm, and image registration method, combined with the unique multi-spectral and high-resolution data characteristics of remote sensing images for feature modeling and data analysis, to ensure that image information is accurately processed at the pixel level or target level.

[0004] Existing technologies often cause information loss and inaccurate feature decoupling due to high complexity when analyzing spectral characteristics. In feature extraction and classification, reliance on a single technology limits the accurate processing of complex areas, affecting accuracy and consistency.

The normalization result is called and the spectral distribution within the wavelength range of each channel is discretized and calculated. The spectral characteristic matrix of each channel is constructed through the discretized spectral distribution array. The spectral characteristic matrix is ​​used as the characteristic expression of the spectral characteristic distribution within the channel, and the coupling degree of the spectral distribution between channels is defined according to the interactive relationship between the data values ​​of each row and each column in the matrix. Specifically, the distribution characteristic value of each channel data is calculated after segmenting, and finally the spectral characteristic matrix of the multispectral channel is formed.

[0021] S112: Calculate the inter-channel fitting matrix according to the spectral characteristic matrix of the multi-spectral channels, perform standardization on the matrix, combine the explicit and implicit parameters of the multi-channels, adjust the weights of the matrix component values ​​according to the weight distribution rule of the characteristic parameters, and generate an explicit and implicit weighted characteristic matrix; First, the row vector and column vector data in the matrix are extracted, and these data vectors are converted into points in the multidimensional vector space. The Euclidean distance matrix is ​​calculated for the relative distribution relationship between the points, and the similarity between the channels is calculated based on the normalized distance matrix. The spectral characteristic values ​​in the characteristic matrix are called and used as the basis for the explicit and implicit parameters. At the same time, the weighting rules for each parameter are set, and the explicit and implicit weighted matrix is ​​generated for each vector data through matrix weighting. Specifically, the weight of each channel data is multiplied by its spectral distribution characteristic value to finally form an explicit and implicit weighted characteristic matrix.

[0022] S113: By performing singular value decomposition on the explicit and implicit weighted characteristic matrix, the judgment relationship between the proportion of multiple characteristic values ​​and the threshold is screened by combining the decomposed characteristic value matrix, and the formula is used: ; Calculate and generate spectral sparse matrix eigenvalues; in, Representative The sparse eigenvalues ​​of the channel, Represents the channel in the explicit and implicit weighted characteristic matrix With channel The component value of Represents the channel in the explicit and implicit weighted characteristic matrix Corresponding to The square of the characteristic value, represents the explicit and implicit weight components, Represents the number of channels, Represents the total number of characteristic values.

[0024] Detailed explanation of the formula and the process of formula calculation and derivation: According to the component data of the explicit and implicit weighted characteristic matrix, the channel sparse characteristic value of the first characteristic matrix is ​​calculated. The explicit and implicit weighted value of each channel is calculated by absolutizing each row value of the explicit and implicit matrix and summing it in the column direction. Perform explicit and implicit distribution ratio allocation, introduce each weight value into the absolute value and calculate , by calculating the sum of the squares of the components in the denominator Take the square root to complete the calculation of the sparse feature value. The example calculation is as follows: Assumptions , in the explicit and implicit characteristic matrix For the following data: ; The weight value is , then the sparse feature value is calculated as: ; Repeat the above calculation steps to obtain the sparse feature values ​​of the remaining channels: ; The results show that the sparse characteristic value reflects the sparsity of the explicit and implicit distribution coupling characteristics between channels. The higher the value, the more significant the sparsity. It is directly related to the eigenvalue of the spectral sparse matrix, providing a basis for subsequent partitioning or classification.

The sparse characteristic components of the spectral channel are obtained through the preceding operations, specifically including normalization and singular value decomposition of the matrix according to the spectral intensity distribution, and classifying the sparse spectral channels after eliminating the components whose singular value contribution is lower than a certain set threshold. The spatial position matrix is ​​further combined, and the position information of the partition is used as the weight factor of the matrix operation. The spatial distribution characteristics of each spectral channel are obtained through weighted calculation, and then the mean and variance are calculated to reflect the overall distribution trend, and the spectral space cross-distribution matrix is ​​generated; S212: according to the partition characteristic values ​​of the spectral space cross-distribution matrix, the components with redundant characteristics in the distribution matrix are eliminated, and according to the frequency distribution characteristics of the characteristic values ​​and the normalization standard, the normalization proportion is determined and adjusted to generate a characteristic normalized distribution matrix; Firstly, the high-frequency and low-frequency component characteristics are extracted from the partition characteristic values ​​of the matrix, and the component characteristic values ​​are classified according to the frequency distribution range. The classification standard of the frequency distribution is calculated based on the standard deviation and mean of the spectral signals of each partition. The significant low-frequency components below the lower limit of the characteristic value frequency distribution range are eliminated, and the normalization operation is completed by adjusting the component frequency distribution weight coefficient. The normalization operation is specifically to normalize the absolute value of each characteristic component by weight so that its distribution range falls within a specific numerical interval, and further calculate the contribution rate of the cross-contribution value of the spectral and spatial components in the normalized distribution matrix. The significant component is judged by the contribution rate and the redundant component is eliminated to generate a characteristic normalized distribution matrix.
