| 摘 要： | 提出一种气球快速泄气过程中动态三维面形的测量方法。用正弦光栅投影到处于快速泄气 过程中的气球表面,使用高帧频CCD获取随时间变化的一系列变形条纹,再采用傅里叶变换轮廓术的方法进行处理,能再现气球快速泄气的整个变化过程。该方法为诸如爆轰、膨胀和萎缩等相关领域的动态过程的研究提供了一种新的方法。 |
| 关 键 词： | 傅里叶变换轮廓术 三维面形测量 气球泄气 |

| Abstract: | A dynamic 3-D surface shape measuring method for a balloon in quickly leaking gas is proposed. The sine grating is projected on the balloon surface that is leaking gas and thus a series of deformed stripes varying with time can be acquired with a high frame frequency CCD. The whole variation process of the balloon leaking gas can be reconstructed after the stripes have been processed by Fourier transform profilometry. The method provides a new means for recording the dynamic process such as detonation, expansion and withering in the related fields. |
| Keywords: | Fourier transform profilometry 3-D surface shape measuring Balloon inflation |
