Embodiment Construction

[0039] The technical solutions of the present invention will be described in detail below, but the protection scope of the present invention is not limited to the embodiments.

[0040] Such as figure 1 and figure 2 Shown, a kind of underwater target recognition method based on light vision of the present invention comprises the following steps:

[0041] (1) Acquire underwater images, and collect images of underwater targets under natural light and artificial light environments respectively through the underwater image acquisition system;

[0042] (2) Image preprocessing, that is, image enhancement, noise location, denoising and color cast correction are sequentially performed on the collected underwater images;

[0043] (3) Target feature extraction: sequentially extract the shape features, color features and texture features of the target;

[0044] (4) Target training and recognition. The shape feature matrix, color feature matrix and texture feature matrix obtained in st...

Abstract

The invention discloses an underwater target identification method based on an optical vision. The method comprises the following steps of respectively collecting an underwater target object image innatural illumination and artificial light source environments through an underwater image collection system; sequentially performing image enhancement, noisy point positioning, denoising and color correction on the collected underwater images; sequentially extracting shape characteristics, color characteristics and texture characteristics of the target; forming a training sample set by use of theobtained shape characteristics, color characteristics and texture characteristics; then carrying out target training; classifying test samples in the natural illumination and the artificial light source; and outputting a classification result. With the underwater target identification method based on the optical vision, the underwater target can be reliably identified.

Description

technical field [0001] The invention belongs to the field of marine engineering, and in particular relates to an underwater target recognition method based on light vision. Background technique [0002] Underwater target recognition technology is an important part of underwater engineering. In the process of military industry development and civilian development and utilization of underwater resources, underwater target recognition technology is an indispensable part.
