| 摘 要： | 将一正弦条纹分别投影到参考物体和待测物体表面,得到参考物体的变形条纹图像和待识别物体的变形条纹图像。以此变形条纹作为联合变化相关的输入图像,通过联合变换相关,得到自相关和互相关输出,最后根据输出的相关峰大小即可判别不同的物体。用Matlab软件编程实现三维物体联合变换相关识别,并且验证了联合变换相关识别物体具有平移不变性。

| Abstract: | Sine fringes are projected to the surface of reference object and target object respectively.Deformed fringe images produced on two surfaces are the input images of joint transformation correlation(JTC),auto-correlation and cross correlation are obtained by JTC.The intensity of correlation peak can be used to recognize the same object.Joint transformation correlation is used in this article to recognize the 3-D object through MATLAB and the translation invariability characters of JTC is also verified. |

| Keywords: | joint transformation correlation Fourier transform auto-correlation cross-correlation translation invariability |
