System and method for observing underwater organisms

Abstract

The invention relates to a system and a method for observing underwater organisms. The system comprises a light curtain scanning array, an image acquisition system, a central area channel, a control module, a data processing module and an output module. The method comprises the steps of: obtaining lateral and vertical continuous width data of fish, calculating the swimming speed of the fish, obtaining lateral and vertical contour information of the fish, collecting image information of the fish, identifying the types and quality data of the fish, obtaining shape and form feature information ofthe fish, and forming three-dimensional images of the fish. According to the invention, the influence on the normal activity of the fish can be avoided, the visual blind area is eliminated, and the observation result has integrity, objectivity and scientificity.

Description

technical field [0001] The invention relates to biological observation technology, in particular to an underwater biological observation system and method based on light curtain scanning and image acquisition technology. Background technique [0002] Currently, underwater observation is usually based on the image acquisition of a single camera or video camera. When this image acquisition technology is used to observe underwater organisms, part of it does not use supplementary lighting. Due to the lack of natural underwater lighting conditions, in order to obtain clear underwater biological observation images, it is often necessary to use artificial light source lighting, and most artificial light sources Illumination is a visible light source. Visible light can stimulate underwater organisms such as underwater organisms, making them tend to or stay away from the light source. Therefore, using visible light as an illumination source will interfere with the observed underwater...

Problems solved by technology

[0005] In order to solve the problem that the existing image acquisition technology is not enough to obtain the complete morphological feature information of the observed creature when observing the morphological feature information of underwater creatures, resulting in the lack of objectivity of the observation results, this invention adopts two groups of vertically arranged A light curtain scanning array composed of a light curtain sensing system with infrared or near ultraviolet light as a light source, and an image acquisition system composed of two near ultraviolet cameras and their corresponding near ultraviolet supplementary light lamps. The biomorphic characteristics of underwater organisms are observed, and the observation results are complete, objective and scientific.
