摘要
为解决传统多视点图像重建算法重建耗时过长、重建后清晰度较差的问题,基于虚拟现实技术设计一种新的多视点图像重建算法,分析摄像机的配置标准与目标图像方位,利用映射法将成像模型投射在二维平面上,再根据映射关系实现信息采集。在确定多视点图像背景后,绘制子区间方向梯度直方图,根据直方图绘制结果描述子情况,与相匹配的图像进行对比分析,对图像进行更精准的细节匹配,实现图像重建。实验结果表明,基于虚拟现实技术的多视点图像重建算法能够有效缩短重建耗时,提高重建后清晰度。
At present,the multi-viewpoint image reconstruction algorithm takes too long to reconstruct,and the definition after reconstruction is poor.Therefore,a new multi-view image reconstruction algorithm based on virtual reality technology was designed Firstly,the configuration standard of the camera and the orientation of the target image were analyzed,the imaging model was projected on the two-dimensional plane by the mapping method,and the information was collected according to the mapping relationship.Secondly,after determining the background of the multi-viewpoint image,the sub-interval direction gradient histogram was drawn,and the sub-situation was described according to the result of the histogram.and then the comparison with the matched image was done,so as to more accurate detail matching on the image was performed to achieve image reconstruction.The experimental results show that the multi-viewpoint image reconstruction algorithm based on virtual reality technology can effectively shorten the reconstruction time and improve the definition after reconstruction.
