Title:
UNDERWATER PHOTOGRAMMETRY-BASED METHOD FOR MEASUREMENT DURING DOCKING OF IMMERSED TUBE SEGMENTS
Document Type and Number:
WIPO Patent Application WO/2024/032663
Kind Code:
A1
Abstract:
An underwater photogrammetry-based method for measurement during docking of immersed tube segments, comprising: determining segment coordinates of a plurality of sets of underwater photogrammetry systems in a segment coordinate system (101); in the segment coordinate system, determining a standard included angle between a connecting line of the segment coordinates of an underwater photogrammetry device and the central axis of a segment to be immersed (102); on the basis of the segment coordinates, determining, in a construction coordinate system, actual coordinates of the underwater photogrammetry device, theoretical coordinates of said segment, theoretical coordinates of the underwater photogrammetry device, and theoretical central axis coordinates of said segment (103); on the basis of at least one of the actual coordinates of the underwater photogrammetry device, the theoretical coordinates of said segment, the theoretical coordinates of the underwater photogrammetry device, and the theoretical central axis coordinates of said segment, the standard included angle, and preset precision parameters required for immersion of said segment, determining adjustment parameters for immersion and docking of said segment (104); and according to the adjustment parameters, controlling and adjusting said segment to be docked with a target docking segment (105).
