matchmove流程中修改Maya相机数据的脚本

matchmove组的流程涉及到syntheyes与maya，nuke交接的问题。syntheyes会生成包含去畸变节点的nuke工程和带跟踪信息的maya工程。在nuke工程上渲染得到去畸变的序列，这是第一步。第二步就是进入maya工程替换去畸变的序列，并修改相应相机参数。

在以往流程中，第二步需要人工完成，涉及到的参数也不少，不熟悉流程的员工时常犯错，是一个流程隐患。

要解决这个问题就需要一个脚本自动完成第二步骤，相机之前的数据可以直接获取，之后的数据可以根据去畸变序列的属性进行换算，于是这个节点的思路便清晰了。

脚本如下，直接保存为.py文件拖到maya工具栏上即可
