【摘要】 在测量船上,其主要测量设备如光测设备、雷达等,均需要以惯导平台提供的地平真北地大地坐标作为基准。本文研制一套新型船体变形测量系统,在各主要测量设备之间,建立精密的光学联系,采用先进的电荷耦合器件,先进的通讯与控制模式将各测量端子获得的图像数据集中到中心控制台,利用性能优良的计算机集中处理各测量端子的测量原始图像数据。该测量控制方案,一方面使各测量端子实现了标准化、模块化设计,提高了系统的可靠性;另一方面,由于采用了数据集中处理模式,所有的校准工作均由中心控制台来统一完成,测量点标校可在中央控制台集中操作,降低了因人员及环境因素导致的测量误差。测出由于船体变形引起的它们相对惯导之间的三自由度变化角,其测量精度达到5″之内。更多还原

【Abstract】 In measuring ship, the main equipments such as optical facility and radar are provided the norm by the intertia navigation system which has the really north. We develop a set of ship distortion system, which based on the contact with all systems by optical equipment. The system includes steel tube, incepting optics equipment, beaming optics equipment,torsion optics equipment. It is fixed the optics equipment in inferior equipment. Every incepting optics equipment takes over the parallel light from the beaming equipment. The incepting optics equipment adopts the auto collimation. When the ship has the angle excursion, the CCD image gives out the angle. The collecting platform disposes the date and transfers it to the directing center. The measuring ship diatortion includes the cell error and fixing error and so on. The cell error is the manufacture, assemble, capability complication. The fixing error includes the arithmetic, estimating dynamic complication. It can measure the angle systems for ship distortion. The error is below 5".更多还原
