为了提高对运动目标的速度模拟精度,采用三维激光技术进行虚拟现实VR建模,提出一种基于三维激光扫描网格高分辨率重构的运动目标图像虚拟视景速度模拟方法。首先采用LOD渲染和三维激光扫描技术进行运动目标的高分辨率网格分区,提取运动目标的动态监测视点,然后采用三角网约束曲面拟合控制方法进行运动目标的高精度速度模拟,得到运动目标在VR视觉中的动态速度变化的分布参数点,实现对目标的高精度速度模拟VR建模分析,最后进行仿真测试。结果表明,采用本文方法进行VR建模和速度模拟的精度较高,虚拟视景渲染的输出信噪比较高,性能较好。
In order to improve the speed simulation accuracy of the moving target, a three-dimensional laser technology is used to model the virtual reality VR. A virtual scene velocity simulation method based on three-dimensional laser scanning grid high-resolution reconstruction is proposed. First, LOD rendering and 3D laser scanning are used to segment the high-resolution grids of moving targets, and the dynamic monitoring viewpoints of moving targets are extracted. Then, the triangulation-constrained surface fitting control method is used to simulate the moving targets with high precision, and the moving targets In the VR vision of the dynamic speed distribution of the distribution of parameters to achieve the goal of high-precision speed simulation VR modeling and analysis, and finally simulation test. The results show that the accuracy of VR modeling and speed simulation using this method is high, and the output of the virtual scene rendering has a higher signal-to-noise ratio and better performance.
