Description

technical field [0001] The invention relates to the technical field of optical instruments, in particular to an intelligent underwater polarization target depth map acquisition system and method thereof based on polarization recognition. Background technique [0002] Traditional machine vision is to project a three-dimensional three-dimensional scene into a flat two-dimensional image. During this imaging process, depth information is lost, making the reconstructed three-dimensional scene not unique, which limits the development of machine vision. Therefore, image-based depth information acquisition has important practical significance and will greatly promote the development of machine vision. [0003] At present, there are roughly two types of depth information acquisition: [0004] One is to obtain depth information through three-dimensional imaging: such as lidar depth imaging and stereo vision technology. The binocular stereo vision in stereo vision has been studied mo...

AI Technical Summary

Problems solved by technology

The above method can realize the acquisition of depth information from a single image, but the solution process is relatively complicated, so the real-time performance is relatively poor

[0006] In underwater scenes, depth information plays an important role in underwater target detection and tracking. However, when the above method is applied underwater, there are serious shortcomings. When light propagates in water, there are serious absorption and scattering. The information cannot reach the acquisition equipment, but the underwater backscattered polarized light contains the distance information of the target
