Online 3D profile measurement is required for various production lines. Light section method is well-known and easy to apply for getting surface profile. But the light section method does not meet speed requirement for online measurement in steel industry. We developed high speed 3D surface profile measurement system based on light section method. By using Time Delay Integration (TDI) camera and modulated light source, profile information is coded as phase shift of fringe. Phase of fringe image is recovered by quadrature demodulation and phase unwrapping. We apply this method to measure steel strip shape and successfully build online measurement system.
