Mosaic floors of surviving buildings in Ostia have been mainly recorded in photographs. From 2008, Japanese research group carries out a project of 3d measuring of the whole structure of ancient Roman...
无标注册是增强现实技术（AR）领域的研究热点，本文提出并实现了一种对未标定摄像机进行内外参数估计的完整方法。该方法采用单幅图像作为输入，三维物体的SfM重建点云作为数据表，进行匹配并采用RANSAC方法去除误匹配得到单应矩阵，结合Kruppa方程得到焦距估计值，并采用PnP问题的LevenbergMarquardt最优化法得到外参矩阵的非线性最小二乘解。为便于观察结果，另建立基于显卡计算的粒子系...
