Digital multimedia dynamic image reconstruction based on 3D laser virtual imaging

针对传统动态图像重建方法存在的三维配准性能低,误差大等问题,提出基于三维激光虚拟成像的数字多媒体动态图像重建方法。采用表面网格检测方法,检测数字多媒体动态图像的边缘轮廓。根据三维激光虚拟成像的中心像素点,对动态特征点进行定位。在主方向生成三维激光虚拟成像包围盒,计算动态图像主成分特征点的位置及所在尺度值,采用激光射线体绘制技术,结合纹理配准法,对数字多媒体动态图像的重建模型进行构建,通过重建模型实现数字多媒体动态图像的重建。实验结果表明,该方法构建的重建模型逼真度高,特征点配准误差低,重建效果好。

Aiming at the problem of low registration performance and large error caused by the traditional dynamic image reconstruction method,a digital multimedia dynamic image reconstruction method based on 3 D laser virtual imaging is proposed. The surface grid detection method is used to detect the edge contour of the digital multimedia dynamic image. The dynamic feature points are located on the basis of the center pixels of the 3 D laser virtual imaging. 3 D laser imaging virtual bounding box in the main direction is generated to calculate the feature position and the scale value of dynamic image principal components. Using laser radiation rendering technology combined with texture registration method,the reconstruction model of digital multimedia dynamic image building is established. And realize the reconstruction of digital multimedia dynamic image by modeling. The experimental results show that the reconstruction model constructed by this method has high fidelity,low registration error of feature points and good effect.
