摘　　要：提出一种新的方法,基于二维坐标内的物理连续性,在相机的拍摄速度很高的时候,前后帧的位移变化很小,寻找一组不变量的基点,利用这些二维地域特征点和基点距离的物理连续性作为参数优化的最小值约束,使用非线性优化方法训练出非刚体运动时的运动结构参数,重建成三维地图区域模型。实验结果表明,该方法优于传统的三维地图重建方法。This paper proposes a new method,the physical continuity of the two-dimensional coordinate based on the camera,at very high speed,displacement changes before and after the frame is very small,point for finding a set of invariants using physical geographical features,these two points and point distance continuity as a minimum constraint parameter optimization,the use of nonlinear optimization method of train movement parameters of non-rigid motion,reconstructed into a three-dimensional map of regional model.The experimental results show that the 3D map reconstruction method,this method is superior to the traditional.
