Embodiment Construction

[0049] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.

[0050] Remote sensing images have the characteristics of timeliness, dynamics, and instability. Timeliness is mainly reflected in the fact that sea targets are constantly changing under the influence of sea wind and waves, and the captured target images usually only have reference value and guiding significance within a certain period of time. Dynamicity refers to the constant cha...

Abstract

The invention relates to the field of image registration, and provides a registering method for dynamic marine remote sensing images. The method comprises the steps: 110, collecting two marine remote sensing images, and respectively marking the two marine remote sensing images as a reference image and a to-be-registered image; 200, constructing a structure invariant descriptor through employing a graph structure construction method, and obtaining the difference of feature points in a graph structure; 300, building a feature matching model for the registration process of the reference image and the to-be-registered image; 400, carrying out the registration of the reference image and the to-be-registered image, and obtaining the optimal feature matching result of the reference image and the to-be-registered image. Compared with the prior art, the method is small in calculation amount, is high in calculation speed, is high in adaptability, and is strong in anti-interference capability.

Description

technical field [0001] The invention relates to the field of image registration, in particular to a dynamic maritime remote sensing image registration method. Background technique [0002] Image registration is a basic problem in image processing applications, which is used to align and superimpose two or more images of the same scene acquired by different sensors, different angles of view, at different times or under different shooting conditions. It has a wide range of applications in many fields, such as remote sensing images, medical image analysis, cartography, computer vision, pattern recognition, etc. Image registration technology can be used in the field of maritime dynamic remote sensing images. Since marine targets such as oil spills and enteromorpha have a great impact on the marine environment, it is necessary to track and monitor the targets in time to facilitate real-time processing by law enforcement agencies. In the monitoring process, it is necessary to est...
