Compared to previous methods the novelties of the proposed method are two-fold . Firstly the proposed method improves computing efficiency and reconstruction precision by weighted iterative implementing using the coded points being easy to match precisely .

与已有方法比较，该方法有两个主要特点：①利用 编码点进行 加权迭代，由于 编码点易于点对精确匹配，提高了算法的运算效率和重建精度；
