从单幅图片出发,通过简单的方法,根据人体的先验知识,从光学角度预测图片中的光源,并对人体图片进行2.5维恢复,以便以后从视频中恢复三维信息.实验表明,在一定条件下,将光源预测应用于人体表面三维形貌的复原是有成效的.本工作为从二维视频恢复2.5维信息提供了简单、实用、可改进的方法.%3D Recovery of human body from a single image is discussed. The light source for the image is predicted by priori knowledge of human body, and the shape of the human body is 2.5D recovered. The experiments indicate that the method of source forecast is valuable for the 2.5D recovery of human body under certain conditions. The study provides a simple, practical and improvable method for the 2.5D recovery of human body shape from 2D information of video.
