颜色编码正弦条纹实现孤立动态物体3维测量
3-D measurement of dynamic and isolated objects based on color-encoded sinusoidal fringe
摘要
Abstract
When 3-D shapes of dynamic objects , especially with isolated area and discontinuous distribution , are measured with the traditional fringe projection and phase analysis method , it is difficult to get reliable expansion phase .A technique based on color-encoded sinusoidal fringe projection was proposed to solve the problem .The projected sinusoidal fringes were marked with two-level encoded color .After capturing the deformed fringe pattern , the fringe order was determined according to the color sequence based on the coded characteristics , and the cut-off phase was unwrapped . Finally, the 3-D shape of the dynamic object with isolate area was reconstructed .The results show the decoding method is stable and reliable .3-D shape of the spatially isolated dynamic objects can be exactly reconstructed with only one shot .关键词
