Underwater three-dimensional reconstruction method based on multi-view binocular structured light

The invention discloses an underwater three-dimensional reconstruction method based on multi-view binocular structured light, which belongs to the technical field of computer vision underwater three-dimensional reconstruction, and comprises the following steps: camera parameter calibration: firstly, adjusting the focal length and aperture of a camera until an obtained image is clear; fixing the focal length and the aperture of the camera to keep the camera unchanged in the image acquisition process, shooting a plurality of groups of calibration plate images, calibrating the internal parameters of the camera by using a Zhang Zhengyou calibration method, and completing the whole parameter calibration process in the air; according to the novel three-dimensional reconstruction method for the underwater target object, the step of watertight processing of the camera is omitted, and the equipment manufacturing cost is reduced; according to the invention, an underwater object can be reconstructed to form a complete t
