在运动力学、弹道学等研究的一些动态过程中，瞬态飞行目标的三维面形与其结构、形变、应力和烧蚀等情况有着密切的关系，而对其面形的多视角测量目前还无法实现。针对这一难题，基于结构光技术设计并搭建了一套正六边形的测量系统，利用三套投影摄像装置将正弦光栅多角度、瞬时、同步投影到瞬态飞行目标的表面，采集其条纹图像，再经小波变换处理，最终得到目标的三维面形。实验结果表明，该系统能有效地实现对瞬态飞行目标复杂三维面形的非接触式、多视角、快速测量。

During the dynamic process of sports mechanics, ballistics, etc., the three-dimensional (3D) surface distribution of the transient moving target is closely related to its structure, deformation, stress, erosion, etc. But the non-contact, multi-view and fast measurement for it is still not realized. In response to this problem, a hexagonal configuration of the measurement system which is based on structured light technology is designed and structured. By using three projectors-camera subsystems, the sinusoidal grating is projected onto the surface of the transient moving target instantaneously and simultaneously. The deformation patterns catched by high-speed CCD are then processed by the wavelet transform. Finally, the 3D surface distributions can be obtained. The experimental results indicate that the system is effective to achieve the non-contact, multi-view and fast measurement for the 3D surface distribution of the transient moving target.
