Abstract

The invention provides underwater laser scanning equipment, which comprises a connection cabin in which an industrial personal computer is mounted; the laser cabin is connected to the connection cabin, and a first distance measuring laser and a line laser are installed in the laser cabin; the camera shooting cabin is connected to the connection cabin, and a second distance measuring laser and a camera are installed in the camera shooting cabin; the industrial personal computer calculates a cabin body deflection angle of the laser cabin and a cabin distance between the laser cabin and the camera shooting cabin according to laser distance measurement data of the first distance measurement laser and the second distance measurement laser based on an auxiliary plate and according to the distance between laser points of the first distance measurement laser and the second distance measurement laser on the auxiliary plate; and the mechanical parameter self-calibration of the underwater laser scanning equipment is completed according to the cabin deflection angle and the inter-cabin distance. The underwater laser scanning device solves the problems that an existing underwater laser scanning device is poor in mechanical compatibility and cannot conduct working mode switching.

Description

technical field [0001] The invention belongs to the technical field of underwater detection, and in particular relates to an underwater laser scanning device applicable to multiple underwater platforms and capable of static and dynamic switching. Background technique [0002] Existing underwater laser scanning equipment is mostly used for a single platform, such as AUV, ROV, or mobile subsea crawler, which cannot be applied to different types of mobile platforms at the same time, and the size of its own equipment is mostly fixed, which is inconvenient Shortcomings of installation; in addition, the existing underwater laser scanning instrument only possesses a single mode of operation, that is, the scanning mode in a static environment (instrument and equipment are fixed at a certain fixed position, and 0-360° is carried out with this position as the axis. Rotary sweep), cannot be carried on the moving underwater platform for scanning of dynamic environment and scanning under...
