Abstract

The invention provides an optical remote sensing image target area detection device and method, which relate to the field of image processing. The device and method for detecting a target area of ​​an optical remote sensing image converts an optical remote sensing image into a three-dimensional image, detects a suspected target area of ​​the optical remote sensing image based on the three-dimensional image, and uses a principal component analysis network and a support vector machine to analyze the target area of ​​the optical remote sensing image. Feature extraction and classification are performed on the suspected target area to determine the target area. The optical remote sensing image target area detection device and method are not easily affected by natural factors such as clouds and sea waves, have high stability, and have low error rate and fast extraction speed for target area extraction.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an optical remote sensing image target area detection device and method. Background technique [0002] The research objects of target area detection in optical remote sensing images mainly include synthetic aperture radar (SAR) images and optical satellite optical remote sensing images. Among them, SAR images have low resolution and high noise, while optical remote sensing images have high spatial resolution, intuitive imaging, rich content, clear target structure, and have advantages that SAR images do not have in target area detection. Therefore, optical remote sensing Image has become a research hotspot in remote sensing image target area detection in recent years. [0003] In the prior art, the target area of ​​the optical remote sensing image is mainly detected by the threshold segmentation method. The threshold segmentation method uses the difference between the gray value...
