航海模拟器三维视景中双吊杆操作的仿真研究

Simulation of Dual-Boom Operation in Three-Dimensional Visual Scene

现代航海教育已经离不开航海模拟器,船舶双吊杆操作的仿真研究对提高双吊杆实际装卸货物专项操作训练具有重要作用。运用笛卡尔坐标系变换算法,构建双吊杆操作的算法模型;结合OSG三维渲染引擎技术,建立求吊货点空间坐标的算法模型;提出QT槽信号机制与OSG相结合,实现船舶双吊杆操作系统仿真的交互。通过获取各点三维坐标值,拟合出操作中各点轨迹并进行比对,结果表明模型交互具有较高逼真性,操作误差小,能够满足操作训练和模拟系统的需求。

Modern navigation education can not be separated from the navigation simulator,the simulation research on the operation of the Dual-derrick is very important to improve the special operation training of the actual loading and unloading cargo.Based on the Cartesian coordinate system transformation algorithm,the algorithm model of the Dual-derrick operation was constructed;based on OSG three-dimensional rendering engine technology,the algorithm model of finding the space coordinate of the lifting point was established;the combination of QT channel signal mechanism and OSG was proposed to realize the interaction of the simulation of the ship’s Dual-derrick operating system.By obtaining the three-dimensional coordinate value of each point,the trajectory of each point in the operation was fitted and compared,and the results show that the model interaction has high fidelity,small operation error and can meet the needs of operation training and simulation system.
