Fusion imaging device and method for sonar and binocular vision imaging system

Abstract

The invention relates to a fusion imaging device and method for a sonar and binocular vision imaging system. The fusion imaging device for the sonar and binocular vision imaging system comprises a rigid support, a sonar imaging system, a binocular vision imaging system and an image signal fusion imaging processing system which connects and fuses the sonar imaging system and the binocular vision imaging system. The sonar imaging system gives out sonar to detect a target object and the rigid support the close to the target object when the target object is discovered; when the distance between the rigid support and the target object achieves the set distance, the binocular vision imaging system is started, and the sonar imaging system and the binocular vision imaging system respectively collect image signals; the fusion imaging processing system fuses the collected image signals to form into a fusion image. The fusion imaging device for the sonar and binocular vision imaging system can effectively detect specific profiles, surface information and depth information of underwater objects, solves the problem that underwater, especially deep-water object perception is difficult, and a powerful solution is provided for underwater, especially deep-water related work.

Description

technical field [0001] The invention relates to an underwater imaging system, and more specifically, to a fusion imaging device and method of a sonar and binocular vision imaging system. Background technique [0002] Object perception underwater, especially in deep water, has always been a difficult problem to solve. Traditionally, the use of sonar to detect objects can only scan the information of one plane, and can only know the approximate position of the object but cannot know the specific outline and surface information of the object.

[0002] Object perception underwater, especially in deep water, has always been a difficult problem to solve

Traditionally, the use of sonar to detect objects can only scan the information of one plane, and can only know the approximate position of the object but cannot know the specific outline and surface information of the object. Moreover, interference in the depth direction and scanning speed are affected by the height of the scanned object. slow

[0003] However, the pictures captured by ordinary cameras do not have the depth information of the object, and cannot perceive the distance relationship between the object and itself.

Using the pure passive binocular vision system with real-time display effect to detect and because of the imaging principle, it must bring imaging errors
