摘要
采用傅立叶变换轮廓术,针对基频提取的关键技术采用逐行傅立叶变换,准确提取基频信息的方法恢复相位信息。在此基础上,以未畸变条纹为基准,得出被测物体的真实位相值。该方法只需一幅条纹图,节约了测量时间。实验证明可实现无接触面型的自动传感。
Fundamental of Fourier Transform Profilometry is adopted, the essential technology to extract base frequency information line by line is adopted through fourier transform of the stripe image, which can enhancement measuring accuracy and phase value of the object is obtained on base of undeformed strip, so a piece of stripe image is needed, and The result show that FTP suits a non - contact 3 - D object shape measurement.
