Abstract

The invention discloses an underwater three-dimensional imaging device and method based on multi-view vision. The underwater three-dimensional imaging device specifically comprises an underwater image acquisition module, an image processing module and a display module. The underwater image acquisition module comprises a lead screw, a left high-definition camera, an LED lighting module and a right high-definition camera. The left high-definition camera, the LED lighting module and the right high-definition camera are installed on the horizontal lead screw, and the left high-definition camera and the right high-definition camera are symmetrically installed relative to the LED lighting module. The image processing module obtains an underwater three-dimensional image from images obtained by the left and right high-definition cameras by sequentially utilizing image preprocessing, camera calibration, stereo matching and three-dimensional reconstruction methods. The display module is used for displaying the underwater three-dimensional image. The underwater three-dimensional imaging device based on multi-view vision can effectively solve the problem of an underwater vision blind area of an underwater laser detector.

Description

technical field [0001] The invention mainly relates to the field of underwater imaging, in particular to an underwater three-dimensional imaging device and method based on multi-eye vision. Background technique [0002] Since the 21st century, countries have gradually shifted their attention from land to underwater environments such as oceans and lakes. Compared with land research and engineering operations, underwater research and engineering operations are greatly restricted. Technicians need to use various instruments to complete underwater environment observation and distance measurement. Underwater imaging technology has gradually been widely used in various underwater operations. [0003] However, due to the strong scattering and absorption of light by water, the attenuation of light under water is very fast, which is far greater than the attenuation of light in the atmosphere. At this stage, underwater laser detection is widely used in underwater imaging technology...
