Bundle adjustment python实现

WebBundle Adjustment即光束法平差,它通过将相机的姿态和测量点的三维坐标作为未知参数,将影像上探测到的用于前方交会的特征点坐标作为观测数据从而进行平差得到最优的相机参数和世界点坐标。 如何表达影像和世界点的关系? Web一、Bundle. Bundle主要用于传递数据;它保存的数据,是以key-value (键值对)的形式存在的。. 经常使用Bundle在Activity之间传递数据,传递的数据可以是boolean、byte、int、long、float、double、string等基本类型或它们对应的数组,也可以是对象或对象数组。. 当Bundle传递的是 ...
