摘要
针对稳像中运动矢量的求取,提出了一种基于光学联合变换相关器的像移探测技术.给出了基于光学联合变换相关器的像移探测原理,并给出了仿真结果.为了验证联合变换相关器的探测准确度,进行了实验验证,验证结果表明探测最大误差为0.8个像素.结果表明,光学联合变换相关器能够很好地探测出运动矢量,进而完成图像稳定工作.相比单纯的软件算法求取运动矢量,基于光学联合变换相关器的像移探测技术能够更快更好地达到目的.
In order to detect motion vector in the image stabilization,an image motion detection technology based on optical joint transform correlator was proposed. The principle of motion detection based on the JTC and the simulation result were given out. In order to illustrate the system＇s detection precision, experiments were made. The results show that the max error is 0. 8 pixel and the motion vector can be effectively detected by JTC to accomplish the image stabilization . Compared to other motion vector detection technology by soft algorithm,the JTC has an advantage of high speed and accuracy.
