Ship Deformation Measurement Technology Based on Visual Measurement Chain

In the process of ship sailing, due to the influence of temperature, wave, motion and other factors, the ship will undergo dynamic flexible deformation. This deformation is difficult to be calculated by the ordinary structural mechanics method, but affects the accuracy of the ship weapon system and the inertial guidance system. This article in view of the dynamic environment of hull deformation measurement requirements, puts forward a hull deformation measurement technique based on the visual measurement chain, composed of a measuring station with multiple camera to multiple station relay to the way of more than 100 meters wide range of hull key parts form variables measurement, for a ship platform experiment provide important reference data.
