Abstract

The invention provides a fusion imaging device of two-dimensional sonar and laser distance gating imaging equipment. The fusion imaging device is characterized by comprising a sealed cabin, an image function enhancing camera, two-dimensional multi-beam sonar equipment, a watertight plug, a lithium battery, an embedded computing hardware platform, a short pulse laser, a helmet display and a two-dimensional adjusting frame. The method has the advantages that 1) the influence of underwater backward scattered light is effectively reduced by adopting laser distance gating imaging equipment, and theoptical imaging quality is greatly improved; 2) a two-dimensional adjusting frame is arranged to facilitate adjustment of view field center positions of the image function enhancing camera and the two-dimensional multi-beam sonar equipment, and a diver can manually remotely control the light beam emitting direction of the auxiliary laser light source, so that an optical image can be convenientlyand rapidly obtained after the acoustic image obtains the position of a target; 3) the structure is simple and practical and can be used as a guiding and collision device for underwater divers, and 4)the overall structure is good in bearing performance and water tightness and high in engineering application feasibility.

Description

technical field [0001] The invention belongs to the technical field of fusion imaging equipment, in particular to a fusion imaging device of two-dimensional sonar and laser range gating imaging equipment. Background technique [0002] Underwater acoustic imaging is in the ocean and other water environments, using sound waves as the medium to receive the backscattered echoes of emitted sound waves, and process them through a certain algorithm to form an image of the observed area. The propagation attenuation of sound waves in water is small, and the propagation distance is long. The commonly used multi-beam two-dimensional multi-beam sonar equipment can give the distance and width information of objects in front of the sonar, which is the most effective for large-scale and long-distance detection and positioning in water. Means, yes, but the disadvantages of sonar images are that the resolution is lower than that of optical images, and the ability to express local features of...
