摘要

针对大规模电子化考场监控

提出基于Fourier-Mellin变换的宽视场图像合成技术.两摄像机采用具有相同(近似)的光学中心固定方式;利用Fourier-Mellin不变描述子和相位相关技术

计算相邻图像序列之间的映射关系

包括旋转、平移和尺度变换参数;拼接中采用无缝缝合

实现对光照不连续的平滑过渡.实验结果表明

该算法可以获得比较理想的宽视场图像

实现了对大规模电子化考场高分辨率的实时监控.

Abstract

An image mosaic method based on Fourier-Mellin transform is presented for large scale electronic testing surveillance.Both camera were set with the same fixed mode of optical center.Fourier-Mellin invariant descriptor and phase correlation technology were utilized to get projective matrix including rotation

translation and scale parameters.A seamless technology was used to smooth the discontinuous of the luminance transform.The experiments show that it is an available image mosaic method for wide field of view surveillance with height resolution panorama.
