sequence contact

The color coded structure light method is becoming popular because of its advantages which are non-contact, high precision and easy to implement, It contains two kinds of encoding methods: timing sequence encoding method and spatial encoding method.

其中基于彩色编码结构光的三维重构技术由于具有非接触、精度高、易实现等优点日益成为研究热点。彩色编码的方法有两种：时序编码法和空间编码法。

On the basis of the inverse die contact tracking method, the track fit revising method is put forward to establish the criterion of node detaching from die, and the time sequence of boundary node releasing from die is determined.

在反向模具接触跟踪方法的基础上，提出了采用跟踪拟合修正方法来建立有限元反向模拟的脱模准则，并采用该方法确定了叶片精锻三维有限元反向模拟中边界节点脱离模具的时间序列。
