Embodiment Construction

[0044] The present invention will be further explained below in conjunction with the accompanying drawings and specific examples.

[0045] Such as figure 1 As shown, a semantic description method of remote sensing images based on multi-level feature fusion includes the following steps:

[0046] Step 1. Constructing a semantic description dataset of remote sensing images, the steps are as follows: obtain the original high-resolution remote sensing images; perform preprocessing on the above-mentioned obtained high-resolution remote sensing images, including image denoising and cropping, and the size obtained in this embodiment is Image data sets between 300-1000; for each image, artificially add semantic description, describe the image content in the form of natural language, each image is described by T sentences, and the image and semantic annotation together form a complete remote sensing image semantic description Dataset; at the same time, download the public remote sensin...

Abstract

The invention provides a remote sensing image semantic description method based on multistage feature fusion, and belongs to the field of remote sensing image processing and computer vision, and the method comprises the following steps: obtaining a high-resolution remote sensing image, and constructing a remote sensing image semantic description data set; training a semantic classification model of the image by using the semantic annotation data set, extracting word description from the image and encoding to obtain semantic features; training a target detection model by using the target detection data set, extracting region-level features of the image and encoding the region-level features to obtain visual features; aggregating the obtained semantic and visual features, namely splicing the two groups of features together; and taking the aggregated multi-level features as the input of Transform, and training an image natural language generation model. The semantic and visual features of the image are utilized, the extracted information comprises the scene information, the regional visual information and the semantic relation of the object, and the generated image semantic description is high in readability and high in accuracy.

Description

technical field [0001] The invention belongs to the field of remote sensing image processing and computer vision, and in particular relates to a natural semantic description method of remote sensing images based on image vision, semantic feature fusion and attention mechanism. Background technique [0002] With the rapid development of sensor technology, human beings' ability to observe the earth is getting higher and higher, and the amount of data obtained has increased significantly. However, the level of information processing seriously lags behind the development of remote sensing data acquisition technology, which makes the massive data not be effectively utilized. It is very important to research and explore the rapid and accurate understanding of remote sensing images with a huge amount of data, extract useful information, and then guide scientific decision-making in agriculture, environment, transportation, military and other fields. [0003] Remote sensing image se...
