摘要：针对现有三维可视化交互系统通用性差、交互能力有限等问题，基于光束逆投影技术以及相对运动坐标系转化原理，设计一套光束逆投影的三维模型可视化交互系统。利用自定义的球坐标系，使旋转功能更完善且可回溯；通过三维光束逆投影实现三维空间点选取功能，并允许存在交互点击误差；实现了模型表面自由绘制空间轨迹的功能。该系统通用性好、交互能力强，可应用于自动控制系统，实现执行机构运动轨迹的自由控制。

Abstract: Aiming at the problems of poor universality and limited interaction capability of existing 3D visualization interaction systems, a 3D model visualization interaction system based on b bundle back projection technology and the principle of relative motion coordinate system transformation is designed. Using a custom spherical coordinate system to make rotation more complete and traceable; Realize the function of selecting three-dimensional spatial points through three-dimensional bundle back projection, and allow for interactive click errors; Implemented the function of freely drawing spatial trajectories on the surface of the model. This system has good universality and strong interaction ability, and can be applied to automatic control systems to achieve free control of the motion trajectory of the executing mechanism.
Keywords: bundle back projection; coordinate system transformation; 3D visualization; spherical coordinate system
