A hyperspectral unknown target detection method based on evm and deep learning

Abstract

The invention belongs to the field of hyperspectral intelligent perception, and discloses a hyperspectral position target detection method based on EVM and deep learning. Known class and unknown class, and divide the data set into training set and test set; S2: Input the preprocessed test sample data into the 3DCNN network for training, save the training model and output the classification feature vector; S3: All training The feature vector of the data and the corresponding category label use the EVM algorithm to establish an EVM model based on the Weibull distribution; S4: Input the preprocessed test sample data into the 3DCNN model and the EVM model, and calculate the probability of belonging to a known class or an unknown class ; The present invention has a clear structure and is easy to implement, and effectively improves the detection accuracy of unknown objects under the premise of ensuring the classification accuracy of known classes.

Description

technical field [0001] The invention mainly relates to the field of hyperspectral intelligent perception, in particular to a hyperspectral unknown target detection method based on EVM and deep learning. Background technique [0002] Hyperspectral image is a three-dimensional spectral image with spectral resolution in the range of 10l order of magnitude, including two-dimensional geometric space and one-dimensional spectral information of ground objects, realizing the integration of atlas. Hyperspectral images have a spectral resolution of nanometers, which can accurately depict the reflection spectrum of different objects, effectively improving the ability to process hyperspectral image classification and recognition. Classification and recognition of ground objects is one of the research focuses of hyperspectral data processing. Hyperspectral image classification is a process of distinguishing and confirming pixels in an image based on the classification of remote sensing ...
