【Abstract】 To improve the velocity simulate precision of moving target,model VR by 3D laser technology and a virtual visual velocity simulation method of moving target based on 3D laser scanning mesh high resolution reconstruction. First,classify high resolution mesh of moving target by using LOD rendering and 3D laser scanning technology.And get the dynamic monitoring point of moving target. Then,do the high precision simulation by using triangle network constraint surface fitting control method. Get the distribution parameters of the object dynamic velocity change in VR visual and realize VR modeling analysis of target high precision velocity simulation. The results show that this method has high precision,high output SNR and good performance.更多还原
