摘要
对联合变换相关技术进行了理论分析,采用液晶光阀(LCLV)、CCD 相机等器件设计了一套单光路、光寻址、双空间光调制器联合变换相关实验系统、进行了单目标、多目标、噪声图像识别的实验研究,测试了系统对图像畸变的敏感性,实验研究了液晶光阀(LCLV)的非线性输入——输出特性对相关结果的影响,最后初步探讨了联合变换相关器畸变——不变图像识别的方法。
In this paper,Joint Transform Correlation technique is disc- ussed,and Joint Transform Correlator experimental system with two optically addressed SLMS is designed.A series of experime- ntal results have been obtained,including single target,multiple targets and noisy image recognititon.We have measured the im- age distortion sensitivity of this system,and the effects of LCLV'S nonlinear input-output character on correlation signds. Finally we have concisely discussed the way of ditortion-invariant image recognition by Joint Transform Correlator.
