After that,the mosaic image can be created by a multiresolution method which can wipe off ghosting and exposure difference.对多幅图像进行特定模式投影后,用约束的相位相关度法求取水平垂直偏移量,然后寻找最佳缝合线,实现图像拼接,最后采用多分辨率算法对全图进行拼接处理去除曝光差异和鬼影。
Image mosaics are very important in creating panorama and existing algorithms can not cope with ghosting and exposure difference efficiently To solve these two problems, we present a new algorithm The first step is to find a best seam line to stitch the images based on dynamic programming Then the mosaic image is created by a multiresolution metho图像拼接在制作全景图的过程中具有重要作用 ,但是现有的方法不能很好地处理鬼影和曝光差异 针对存在的问题 ,提出了一种实现图像拼接的算法 首先利用动态规划的方法在要进行拼接的图像中找到一条最佳的缝合线 ,然后利用多分辨率技术进行拼接 ,解决了鬼影和曝光差
Image mosaic has been researched for several years,but still it is hard to realize mosaic without ghosting and exposure difference.虽然图像拼接技术已进行多年研究,但是鬼影和曝光差异仍然难以消除。
A laser generation and optical difference detection method of surface acoustic waves(SAW) is used to study the influence of laser source on SAW.利用激光激发声表面波及光差分技术研究激光源对声表面波的影响。
The surface acoustic waves(SAWs) were excited by employing a Nd:YAG laser on the sample Al plate with artificial surface-breaking defects and detected by a kind of optical difference detection system based on the optical beam deflection technique using a He-Ne laser.利用Nd:YAG脉冲激光器、He-Ne激光器和平衡接收器构建一套基于光束偏转法的光差分检测系统,测量了表面带缺陷Al样品的声表面波(SAWs)。
