摘　　要：针对在快变化动态过程三维轮廓术中,成像设备拍摄频率不满足抽样定理,对物体表面动态条纹时间采样不足以及物体表面发生破裂的动态过程,提出一种采用标记条纹进行跟踪的动态过程三维轮廓术,能有效地解决因成像设备时间采样不足和条纹断裂对三维相位展开所带来的影响问题,获得物体正确的动态面形分布,计算机模拟证实了此种方法的正确性。The deficiency of CCD＇s sampling time resulted from slow shooting frequency and breaking surface of measured object bring some difficulties to the 3-D surface restoration of dynamic process.Therefore,a novel method of 3-D restoration for high movement process is proposed in this paper,some problems caused by deficiency of sampling and breaking fringes are solved in 3-D phases unwrapping,and the proper 3-D shape of measured object is obtained. Computer simulation have proved the feasibility of this method.
