摘　　要：现有的场景管理系统由于成像技术的原因,进行人机交互时出现画面卡顿、清晰度下降的现象,因此,设计一种基于三维激光成像技术的场景管理系统设计。系统中的画面显示主要应用的是三维激光成像技术,系统的硬件设计中,根据激光测距的过程,选择测量距离、测量精度等参数合适的激光测距仪;在软件设计中,需要对动态碰撞检测进行优化,采用了八叉树空间剖分法对需要成像的空间进行分割,利用场景管理器完成相交情况查询,优化命名需要碰撞的物体并在后台代码中手动添加判断条件,选择色彩空间以及着色器,实现场景美化,至此完成系统设计。为验证设计系统的有效性,对三种系统进行测试,测试结果表明,设计的系统具有良好的FPS值与图像清晰度,说明设计的系统在实际应用中相对于现有系统具有更好的成像性能。Due to the reason of imaging technology,the existing scene management system appears the phenome-non of picture jam and sharpness decline when human-computer interaction.Therefore,a scene management system design based on 3D laser imaging technology is designed.The main application of the screen display in the system is 3D laser imaging technology.In the hardware design of the system,according to the process of laser ranging,the laser rangefinder with suitable parameters such as measuring distance and measuring accuracy is selected.In the software de-sign,the dynamic collision detection needs to be optimized,the space that needs to be imaged is segmented by octree space division method,and the scene management is used The system completes the intersection query,optimizes the naming of objects to be collided,manually adds judgment conditions in the background code,selects color space and shaders,realizes scene beautification,and thus completes the system design.In order to verify the effectiveness of the design system,three systems are tested.The test results show that the designed system has good FPS value and image clarity,which shows that the designed system has better imaging performance compared with the existing system in practical application.
