摘要
高分辨率三维轮廓的测量在现代社会有着广泛应用,本文对正弦光栅相位调制的三维测量方法进行了理论研究,用计算机控制数字投影设备产生正弦条纹光栅,利用CCD采样分步移相的图案,通过解包裹的方法获得物体的三维信息,测量精度达到10微米。
The measurement of high-resolution three-dimension contours has been widely used. In this paper,three-dimension measurement method of phase modulation of sinusoidal grating is studied theoretically. The digital projection equipment is used to generate sinusoidal grating. CCD is applied to sample pictures generated by stepwise phase shift method. Three-dimension information of the object is obtained by the method of unwrapping, and the measuring accuracy is up to 10 microns
