Problems solved by technology

[0003] However, the optical identification method is flawed, because the propagation of light in water is attenuated exponentially, resulting in a limited range of action of the captured image
Light will also attenuate and scatter in water. The low-frequency light (red light, yellow light) has a low scattering rate and the high-frequency light (blue, green) has a high scattering rate, resulting in common color distortion in underwater optical images.
When using sonar to acquire image data, it is easy to be interfered by ocean environment noise, propeller noise, etc. Underwater acoustic images have great noise influence, low definition, and unclear and incomplete edge contours, which will lead to inaccurate features and affect the imaging effect.

Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0027] It should also be...

Abstract

The invention relates to the technical field of image processing, in particular to an underwater visual identification method and system and a computer readable storage medium. The method specifically comprises the following steps: an image acquisition step; a preprocessing step; a noise reduction step; and a fusion step. According to the underwater visual identification method provided by the invention, an obtained optical image is preprocessed and enhanced to obtain a clearer optical image, an obtained acoustic image is subjected to noise reduction processing to obtain a clearer acoustic image, then processed optical image data and acoustic image data are fused to obtain a final composite image, and the obtained composite image can display underwater image information more accurately.

Description

technical field [0001] The invention relates to the technical field of image processing, and relates to an underwater visual recognition method, system and computer-readable storage medium. Background technique [0002] At present, there are mainly two methods of underwater visual recognition: optical recognition or acoustic recognition. Optical imaging mainly relies on cameras to observe the surrounding environment of water bodies, and acoustic imaging mainly relies on sonar to detect objects. [0003] However, the optical identification method is flawed, and the range of the captured image is limited due to the exponential attenuation of light propagating in water. Light will also attenuate and scatter in water. Low-frequency light (red light, yellow light) has a low scattering rate while high-frequency light (blue, green) has a high scattering rate, resulting in common color distortion in underwater optical images. When using sonar to acquire image data, it is easy to be...
