- 摘要运用导数定义求某些不能用基本公式直接计算的函数的导数。
Using definition of the derivative to find the derivatives of some function that can not be caculated directly with the formula. - 算法采用信息熵度量对象之间的相似性,通过数据直接计算相似性阈值。
In this algorithm, similarity between objects was measured by using entropy and similarity threshold was calculated directly by using data. - 首先根据三个标定点对估计旋转矩阵,然后根据相机和一个点对的几何关系直接计算平移向量。
It firstly estimates the rotation matrix according to three point pairs, then directly calculates the translation sector from the geometric relationships between the camera and one pair of the points.
