A New Type of Underwater Laser Target Intelligent Recognition System

Abstract

The invention discloses a novel underwater laser target intelligent recognition system, which consists of an underwater laser radar, a three-dimensional sample library, a two-dimensional image database and an underwater laser target recognition host computer system. The computer system consists of sample distributed image generation module, feature extraction module, convolution attention module, feature selection module, feature fusion module, decision-making module, output and display module, etc. And a target recognition algorithm based on underwater three-dimensional samples is proposed. The beneficial effects of the present invention are mainly manifested in the realization of multiple images extracted from three-dimensional samples and effective feature extraction, which can identify moving targets in turbid waters, with high recognition accuracy and high intelligence, and at the same time solve the problem of traditional underwater laser recognition systems. The ubiquitous problems such as loss of features when converting three-dimensional samples into two-dimensional images, large noise in turbid water images, and recognition of moving targets with small number of samples.

Description

technical field [0001] The invention relates to the field of computer vision, the field of intelligent identification algorithms, the field of laser radar, and the field of underwater target identification, and in particular, to a new type of underwater target intelligent identification technology based on laser radar. Background technique [0002] The ocean covers more than 70% of the earth's total area, and has a lot of resources and space. However, the ocean space that has been explored by human beings is only about 5% of the total space of the earth, and the ocean has an important military strategic position and resource exploitation and utilization status. And due to the unpredictable and unknown nature of the marine environment, using humans to explore the marine environment has a high probability of causing casualties. Therefore, exploring the underwater world with modern intelligent technology is on the agenda. At present, the commonly used methods for collecting un...
