动态过程三维面形测量的频闪结构光照明系统设计

A System of Sroboscope Structured Illumination for Dynamic Process Three-Dimensinal Measurement

在动态过程三维面形测量中,将频闪效应与三维面形测量技术相结合,提出了一种采用短脉冲频闪光投影结构光场到动态过程表面的频闪结构光照明系统,完成了该频闪结构光照明系统的核心部件——频闪同步控制单元的设计,建立一个将物体运动、频闪结构光照明和图像采集系统三者之间严格同步工作机理,为动态过程的面形变化研究提供了一个理想使用的照明系统。

Combining 3 - D shape measurement with stroboscopr technology in dynamic process, a system of stroboscope structured illumination is porposed in this paper. The synceontrol unit of stroboscope illumination is designed, which is the core of the illumination system. By synchronizing the flash of strucured illumination and shoot of the camera with the motion of the object,the system can ＂ slow down＂ , or even ＂ freeze＂ the motion of the moving object. This system is suitable for wide use in shape studying of dynamic process.
