计算三维重建的方法称为SfM（StructurefromMotion）.\假设计算机已经标定，计算重建的部分可以分为下面四个步骤：\（1）、检测特征点，然后在两幅图间进行特征点匹配。
\（2）、有匹配算出基础矩阵。
\（3）、由基础矩阵计算照相机矩阵。
\（4）、三角剖分这些三维点。

NumPy系统是Python的一种开源的数值计算扩展。
这种工具可用来存储和处理大型矩阵，比Python自身的嵌套列表（nestedliststructure)结构要高效的多（该结构也可以用来表示矩阵（matrix））。
据说NumPy将Python相当于变成一种免费的更强大的MatLab系统。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
