Embodiment Construction

[0034] Hereinafter, embodiments of the present invention will be described more fully with further reference to the accompanying drawings, in which embodiments of the invention are shown. Embodiments of the invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure is thorough, and will fully convey the scope of the invention to those skilled in the art.

[0035] First, the local binarization LBP algorithm involved in the present invention is introduced. The earliest LBP algorithm was proposed by Ojala for texture analysis. The original LBP operator is defined as comparing the gray value of the adjacent 8 pixels in a 3*3 window with the center pixel of the window as the threshold. If the surrounding pixel value is greater than the center pixel value, the pixel The position is marked as 1, otherwise it is 0. In this way, 8 poin...

Abstract

The invention discloses a method for extracting targets through a remote sensing image. The method comprises the following steps that region segmentation is conducted on the remote sensing image to obtain local candidate images containing the targets; in the local candidate images, image regions corresponding to the targets are extracted, and local extraction results are obtained; according to position information of the local candidate images, the local extraction results of all the local candidate images are merged to generate a global extraction result. Meanwhile, the invention further discloses a device for extracting the targets through the remote sensing image. Through the method, the targets in the remote sensing image can be automatically identified and extracted, the calculation quantity is reduced, calculation accuracy is improved, and the calculation speed is increased.

Description

technical field [0001] The invention relates to a method and a device for extracting a target in a remote sensing image, in particular to a method and a device for extracting a breeding box by using a remote sensing image. Background technique [0002] my country's aquaculture industry is developing rapidly, especially in coastal areas. The current production assessment, environmental impact, and rational planning of aquaculture have become one of the hot issues in marine ecology and environmental science research. At this stage, when extracting breeding boxes from remote sensing images, manual interpretation is usually used to monitor the breeding area containing the breeding boxes. However, this method is time-consuming and labor-intensive, and may make mistakes due to the fatigue of the interpreters. Therefore, aiming at the deficiencies of existing manual interpretation, a variety of methods for extracting breeding boxes in remote sensing images have been proposed. [0...
