| Abstract: | Computer data processing of the high speed(50?104fps)moire patterns discribing 3-D shape change cource of thin aluminium plate driven by a detonator has been done by using the digital image processing technique,the least square curve imitation theory and the computer graphics. The 3-D shapes of the defor-ming object have been respectively reconstructed from the 2-D moire patterns. The. precision of the high speed projection moire method has been achieved within ?5 percent. |
