The invention provides a fusion imaging device based on two-dimensional sonar and auxiliary laser lighting imaging equipment. The fusion imaging device is characterized by comprising an airtight cabin, a camera, two-dimensional multi-beam sonar equipment, a waterproof plug, a lithium battery, an embedded computer hardware platform, an underwater auxiliary laser source, a helmet display and a two-dimensional adjusting bracket. The fusion imaging device has the advantages that regulation of central position of a field of view of the camera and the two-dimensional multi-beam and fusion algorithmprocessing of two types of images are facilitated; divers can remotely control the light beam transmission direction of the auxiliary laser source conveniently while optical images can be acquired rapidly after position of a target is acquired through the acoustic images; the fusion imaging device is simple and practical in structure and can be used as a guide and collision device for divers in water; the overall structure of the fusion imaging device has good bearing capacity, good water tightness and high engineering application feasibility.
Description
Technical field [0001] The invention belongs to the technical field of fusion imaging equipment, and particularly relates to a fusion imaging device of two-dimensional sonar and auxiliary laser illumination imaging equipment. Background technique [0002] Underwater acoustic imaging is to use sound waves as a medium to receive backscattered echoes of emitted sound waves in water environments such as oceans, and process them through certain algorithms 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 sonar can give the distance and width information of the object in front of the sonar. It is the most effective means for large-scale and long-distance detection and positioning in the water. But the disadvantage of sonar images is that the resolution is lower than that of optical images, and the local feature expression ability of the target is poor. ...
