摘要
根据船舶操纵模拟器研制的需要,依据视景的圆柱面环幕透视投影模型、透视投影误差校正模型和船舶在海上用罗经进行测向的基本原理,建立了大型船舶操纵模拟器罗经测向的方位角误差纠正模型,并根据误差角度的不同范围要求,给出罗经离视点位置的选择范围,为罗经位置的设置提供参考。
For the needs of ship handling simultor manufacture, the authors build a model of correcting errors of object bearing measured by the compass in ship handling simulator, based on the model of cylinder screen perspective projection, the correcting model of errors incurred by the perspective projection and the basic principles of bearing finding by compass. By using the model, the reference can be provided for the position setting of compass by giving the range of distance from viewpoint to compass according to the range of bearing error.
