摘要
针对传统力觉交互操作过程复杂、模拟物理场景不真实的问题,提出支持嵌入式Web服务器的多层级力觉交互仿真研究方法。在嵌入式Web服务器的基础上添加离散LOD模型,计算相对交互速度,获得目标多层级的序列号进行碰撞计算,构建速度驱动模型。将碰撞检验离散速度驱动模型与SCP层级映射算法相结合,判定映射约束线段、映射约束包围盒单元,运用GHOST SDK计算二者的正交函数,确认满足模型的限制速度阈值条件,从而获得模型的速度参数值以及切换速度,完成力觉交互研究。仿真结果证明,所提方法可以有效解决力觉交互过程中出现的振动现象,提升场景真实感,并且计算简便,具有较高的稳定性与适用性。
Due to complex process of traditional haptic interaction and unreal simulation of physical scene, this article puts forward a method of simulating multi-level haptic interaction supporting embedded web server. Based on embedded web server, discrete LOD model was added, and relative interaction speed was calculated to obtain the multi-level serial number of targets for collision calculation. Moreover, the speed driven model was built. The discrete speed driving model of collision test was combined with the SCP hierarchical mapping algorithm, so that the mapping constraint line segment and mapping constraint bounding-box unit were determined. Meanwhile, GHOST SDK was used to calculate the orthogonal functions and confirm the threshold condition of limited speed that satisfied the model, and thus to obtain the speed parameter and switching speed of model. Finally, the research on haptic interaction was completed. Simulation results show that the proposed method can effectively solve the vibration phenomenon in the process of haptic interaction, improve the reality of scene, and the calculation is simple with high stability and applicability.
