A new method of 360° turning 3D shape measurement is presented in which light sectioning and phase shifting techniques are both used. A sine light field is applied in the projected light stripe, meanwhile phase shifting technique is used to calculate phase of the light slit. The wrapped phase distribution of the slit is formed and the unwrapping process will be made by means of the height information based on the light sectioning method. So phase measuring results with better precision can be obtained. The target 3D shape data can be produced according to geometric relationship between phase and the object heights. The principles of this method are discussed in detail and experimental results are shown.
