Embodiment Construction

[0050] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0051] Such as figure 1 As shown, the large-scale AUV collision avoidance obstacle autonomous identification system of the present invention includes a multi-beam forward-looking sonar, a collision avoidance computer and a central control computer, and the multi-beam forward-looking sonar and the collision avoidance computer communicate through a network. After the beam forward-looking sonar is powered on, it waits for the control command of the collision avoidance computer. When receiving the work order, it immediately returns the sonar data to the collision avoidance computer. The collision avoidance computer receives the sonar data for real-time processing, and simultaneously controls the multi-beam forward-looking sound accept. The collision avoidance computer is connected with the central control computer through RS422, and the collision avoidance co...

Abstract

The invention discloses an obstruction automatic recognition system for collision preventing of a large-scale autonomous underwater vehicle (AUV) and belongs to the technical field of digital image processing. The system comprises a multi-beam foresight sonar, a sonar computer and a central control computer. Network communication passes between the foresight sonar and the sonar computer. The sonar computer is connected with the central control computer through RS 422. The multi-beam foresight sonar collects information of an obstruction. The information is converted to an image and is sent to the sonar computer. The sonar computer receives the image and figures out information about distance, location, size of the obstruction in real time and sends the information to the central control computer. The obstruction automatic recognition system for the collision preventing of the large-scale AUV is strong in real-time judging of the obstruction, free of prior knowledge and suitable for the large-scale AUV.

Description

technical field [0001] The invention relates to an autonomous obstacle identification system, in particular to an autonomous obstacle identification system for large-scale AUV collision avoidance, and belongs to the technical field of digital image processing. Background technique [0002] At present, the world is facing three major problems of population, resources and environment. With the rapid economic development of various countries and the continuous increase of population, human beings consume more and more natural resources, and the resources on land are facing exhaustion, while the oceans and the bottom of the oceans, which account for 71% of the earth's surface area, contain extremely rich biological resources. and mineral resources. As one of the undeveloped treasure land and high-tech fields of human beings, the ocean has become an important strategic goal of various countries and the focus of fierce international competition in recent years. Many countries are...
