Abstract

The invention relates to an interferometric inverse synthetic aperture radar three-dimensional image classification method and device and a storage medium, and the method comprises the steps: projecting elevation scattering points of a three-dimensional InISAR image to a two-dimensional image, and representing the elevation information through the depth of a color, acquiring a classification result through a convolutional neural network, a region suggestion network, spatial pyramid pooling, a full connection layer and a Softmax classifier; or extracting a plurality of microscopic feature vectors of each point of the three-dimensional InISAR point cloud image by using a plurality of multi-scale multi-layer perceptron; splicing a plurality of microscopic feature vectors, global feature vectors and local feature vectors of each point, performing feature extraction on the spliced image by using a multi-layer perceptron, performing pooling dimension reduction, and obtaining a classification result by using a Softmax classifier. According to the method, a deep network based on a Faster R-CNN algorithm framework and a PointNet algorithm framework is provided, so high-efficiency and high-accuracy classification of the three-dimensional InISAR image is realized.

Description

technical field [0001] The present application relates to the technical field of interferometric inverse synthetic aperture radar image processing, in particular to a three-dimensional image classification method, device and storage medium of interferometric inverse synthetic aperture radar. Background technique [0002] Inverse synthetic aperture radar (Inverse Synthetic Aperture Radar, hereinafter referred to as ISAR) adopts single-antenna technology to only obtain the two-dimensional image of the target in the range-Doppler dimension projection, but cannot obtain the three-dimensional image of the target, which is very important for target recognition, especially Automatic identification causes great trouble. [0003] Interferometric Inverse Synthetic Aperture Radar (Interferometric Inverse Synthetic Aperture Radar, hereinafter referred to as InISAR) combines interferometric technology with ISAR technology to achieve three-dimensional imaging of targets. For example, the...
