Embodiment approach

[0111] According to an embodiment of the present invention, the CFAR target detection module performs CFAR target detection on the segmented image, including: (1) using the distribution statistical model to establish a statistical model of the ocean background; (2) setting the virtual alert rate;

[0112] Among them, distribution statistical models include Rayleigh distribution, K distribution, Gaussian distribution, GO distribution, Gamma distribution, generalized Gamma distribution, lognormal distribution and Alpha steady-state distribution, etc.

[0113]Setting the false alarm rate based on empirical values ​​is based on optical remote sensing images of different scales and the sparse distribution of ship targets on the sea, and an adaptive sliding window ship target detection algorithm is designed. It mainly includes: fitting the sea clutter distribution model in different sea conditions , Adaptive sliding window construction and object candidate region acquisition.

Abstract

The invention relates to a method, a system, an electronic device and a computer-readable storage medium for detecting a ship target by a space-borne visible light detector, wherein the method includes: performing image preprocessing on an optical remote sensing image to enhance image details; performing image preprocessing on the preprocessed image Sea and land segmentation; perform constant false alarm target detection on the segmented image; after detection, perform target feature extraction on the image; perform target detection based on auxiliary features such as gray-level co-occurrence matrix on the extracted target features, and output the target detection results. According to the method for detecting a ship target by a spaceborne visible light detector of the present invention, the relevant image features of the optical remote sensing image are fully utilized, and more accurate detection of the ship target in the optical remote sensing image is realized.

Description

technical field [0001] The invention relates to the field of intelligent processing of satellite remote sensing information, in particular to a method, system, electronic equipment and computer-readable storage medium for detecting a ship target by a space-borne visible light detector. Background technique [0002] The realization form of constant false alarm rate detection is constant false alarm rate detector. According to the sensitivity of constant false alarm rate detector to clutter, constant false alarm rate detector can be divided into non-parametric constant false alarm rate detector and parametric type constant false alarm rate detector, and the non-parametric detector has no strict requirements on the type of clutter, but the constant false alarm rate effect of this kind of detector is poor. The parametric constant false alarm rate detector needs to predict the type of clutter. This kind of detector has a better constant false alarm rate effect and is currently wi...
