摘要/Abstract

摘要： 针对头盔上弹痕的三维轮廓测量，提出了采用基于双参考面的条纹投影傅里叶变换法．改变一般测量中只选择一个平面作参考面的做法，引入无弹痕时的头盔表面作为测量的第二参考面，克服了单平面参考面测量时的信息丢失，保证了准确性．测得了弹痕的实际三维轮廓．实验证实了其正确性，精度可达0.1mm．

Abstract: Aimed at measuring the bullet mark on the helmet, the fringe projection Fourier Transformation Profilometry (FTP) based on double reference surfaces is proposed. The second reference surface, which is the helmet surface without damage, is introduced. This method is different from the convenient measuring method, which only uses one reference plane, and avoids the loss of information and insures accuracy in measurement. Experiments prove that this method is availd, and that precision is up to 0.1mm.

Key words: Fourier transformation profilometry, 3-D profile measurement, double reference surface, bullet mark
