Abstract
A real-time monitoring system for float-over installation in ocean engineering, which relates to real-time monitoring for the relative position between the leg mating unit and the stabbing cone of upper module, mainly includes: a shooting collection system and a real-time processing and displaying system, the shooting collection system mainly including a CCD camera and a high light-reflecting landmark, the high-precision CCD camera being a graphic information collecting device, and the high light-reflecting landmark being a mark made of high light-reflecting and light-absorbing materials; a real-time processing and collecting system, which receives and displays in real time, analyzes and stores the graphic information, capable of calculating the coordinates of relative position between the stabbing cone and the leg mating unit in real time. The system achieves real-time close-range photogrammetry for the position of the leg mating unit, characterized by clear positioning, explicit functions, being easy to realize the structures, thus solving the difficult problem that the relative position between the leg mating unit (LMU) and the stabbing cone of the module is difficult to be measured accurately in real time during the float-over installation.
