【摘要】：為了提高對(duì)運(yùn)動(dòng)目標(biāo)的速度模擬精度,采用三維激光技術(shù)進(jìn)行虛擬現(xiàn)實(shí)VR建模,提出一種基于三維激光掃描網(wǎng)格高分辨率重構(gòu)的運(yùn)動(dòng)目標(biāo)圖像虛擬視景速度模擬方法。首先采用LOD渲染和三維激光掃描技術(shù)進(jìn)行運(yùn)動(dòng)目標(biāo)的高分辨率網(wǎng)格分區(qū),提取運(yùn)動(dòng)目標(biāo)的動(dòng)態(tài)監(jiān)測(cè)視點(diǎn),然后采用三角網(wǎng)約束曲面擬合控制方法進(jìn)行運(yùn)動(dòng)目標(biāo)的高精度速度模擬,得到運(yùn)動(dòng)目標(biāo)在VR視覺中的動(dòng)態(tài)速度變化的分布參數(shù)點(diǎn),實(shí)現(xiàn)對(duì)目標(biāo)的高精度速度模擬VR建模分析,最后進(jìn)行仿真測(cè)試。結(jié)果表明,采用本文方法進(jìn)行VR建模和速度模擬的精度較高,虛擬視景渲染的輸出信噪比較高,性能較好。
[Abstract]:In order to improve the accuracy of velocity simulation for moving targets, 3D laser technology is applied to virtual reality VR modeling. A virtual visual speed simulation method of moving target images based on 3D laser scanning grid high resolution reconstruction is proposed. High resolution grid partition using LOD rendering and 3D laser scanning technology of moving target, the dynamic monitoring of view moving object extraction, and then using high precision speed constraint surface fitting control method of moving target triangle network simulation, get the distribution parameters of the moving target in dynamic speed VR visual changes in the simulation, VR modeling high precision velocity analysis on the target, finally carries on the simulation test. The results show that the precision of VR modeling and speed simulation is high, and the output signal to noise of virtual scene rendering is higher and the performance is better.
