摘要
采用当前方法构建的多模数字平台重现目标时,出现重建结果与目标之间的差距较大,重现所用的时间较长,重现结果还原度低和重现速率低的问题。提出基于全息激光打印3D图像的多模数字重现平台构建方法,主要通过三维点云数据的计算、3D计算全息和3D全息显示3大部分构建多模数字重现平台。在分析目标物体结构的基础上采用运动恢复结构算法获取重建目标结构的三维信息;在目标结构三维信息的基础上利用迂回相位编码方法,通过计算机模拟物理干涉全息成像的过程,得到全息图;将全息图传送到空间调制器中采用发光二极管和线性激光源照亮全息图,完成多模数字的重现。实验结果表明,所提方法得到的重现结果与目标之间的差距较小,重现所用的时间较短,验证所提方法的重现结果还原度高、重现速率高。
When the multi-mode digital platform constructed by the current method reproduces the target,there is a large gap between the reconstruction result and the target,the time taken for reproduction is long,and the reproduction result is low in reproduction degree and the reproduction rate is low.A multimode digital reproduction platform construction method based on holographic laser printing 3D image is proposed,which mainly constructs multi-mode digital reproduction platform through three-dimensional point cloud data calculation,3D computational holography and 3D holographic display.Based on the analysis of the structure of the target object,the motion recovery structure algorithm is used to obtain the three-dimensional information of the reconstructed target structure.Based on the three-dimensional information of the target structure,the hologram is obtained by computer simulation of the physical interference holographic imaging process.The hologram is transmitted to the spatial modulator,and the hologram is illuminated by a light-emitting diode and a linear laser source to complete the reproduction of the multi-mode digital.The experimental results show that the difference between the reproducible result and the target is small,and the time used for reproduction is shorter.The re-success of the proposed method is high and the reproduction rate is high.
