Abstract
In order to improve the virtual reconstruction effect of laser 3D images,a laser 3D image virtual recon-struction method based on visual communication technology is proposed.Obtain texture feature values of laser 3D ima-ges,collect laser 3D images,and extract laser 3D image reconstruction features;Fusing frequency domain features and texture features to obtain a laser 3D image multi feature dataset and bad features within the laser 3D image multi feature dataset,and designing steps for multi feature fusion;Based on the results of multi feature fusion,a three-dimensional specific laser 3D image model is obtained to achieve virtual reconstruction of laser 3D images.The experimental results show that the system can effectively solve the problem of laser 3D image reconstruction.When the occlusion ratio is 18％,the scale invariant depth error value and average angle error value both reach the maximum,and the maximum value does not exceed the set threshold.The structural similarity of the method in this paper is over 90％,and the re-construction accuracy is high,which can achieve high-precision virtual reconstruction of laser 3D images.
