摘要
根据大型船舶操纵模拟器研制的需要,对模拟器7通道270°宽视场角环幕投影视景的圆柱面环幕透视投影进行分析,建立了圆柱面环幕透视投影变换模型和圆柱面透视投影误差纠正模型。并针对大连海事大学的船舶操纵模拟器进行分析,求出该模拟器环幕透视投影可能产生的最大误差及所需的误差纠正值。分析结果表明,该大型船舶操纵模拟器所作的误差校正满足航海模拟器对视景的误差要求。
In this paper, the authors analyze the cylinder screen projection in the visual system of ship handling simulator, build the model of the cylinder screen perspective projection, and correct the errors of perspective projection. Also a detailed analysis of the biggest error incurred by the perspective projection is presented in this paper. The result of the analysis shows that the error correction made meets the requirements of visual system in ship handling simulator.
