It emphasizes the main modules including laser drawing machine, software and gratingimage processor.
并着重介绍了激光光绘机、软件、光栅图像处理器等主要组件。

The preprocessing methods of gratingimage are studied, and the 3d object surface data is reconstructed.
研究了光栅图象的投影、采集及预处理方法，并对得到的被测物体表面三维数据点进行重构显示。

The Fourier transform profilometry as an active optical 3d shape measurement technology has been widely concerned because it need only one deformed gratingimage to make full-field analysis.
