组内是否有从事数字图像处理的朋友？
现在有一个任务，需要获取一张清晰的电路板照片。但是，手头上只有一台像素非常低的傻瓜相机。如果拍摄一张完整的电路板照片，那么画面会非常模糊，电路板上的丝印会看不清楚。所以，我打算拍多张局部的清晰的照片，然后用软件合成一张完整的清晰的照片。目前找到的解决方案是使用Photoshop中的image merge（如果没记错名字的话）功能。
可是Photoshop很贵……
况且我对亲手写一个实现这个功能的算法比较感兴趣。了解下来，GNU Octave的image工具箱可以用作数字图像处理，网上也找到一些简单的入门教程，可是对我有直接帮助的资料还没有找到。
组内的高手可否帮忙推荐一些图像拼贴方面的资料，论文、教程都可以，语言不限。如果是用MATLAB实现的也是可以的。

自己写的话基于OpenCv现成的sample就可以了。这玩意学名叫image stitching，手机上拍全景图经常用到Opencv来实现和加速。

你要的是完成一次图片拼接的工作任务，而不是跳进图像处理的坑里。
确实，PS 很贵，难道你不知道还有个叫 gimp 的免费软件么？ 功能一点不比 PS 差， 对付你当前这种属于鸡毛小菜。
如果你坚持要图像拼接的资料，祝你一切顺利。

你可以随便找一台扫描仪扫一下，效果挺不错的。卙比专业的PCB缺陷检测设备。扫的时候可以把DPI调到最高：）
图像拼接基本上是先找两图的特征点做匹配（SIFT？），然后得到一个旋转平移变换后给其中一图做一下变换再合起来。理论方面，随便搜了个综述，可以参考参考：

谢谢各位！
我很多次提议领导买一台扫描仪——至少买一台牛逼一点的相机，可是领导不愿花这个钱。可把我害惨了。

像素低的话,什么算法都没有用的,,,
建议给 iPhone 配置个支架,再安装个拼图app ,

跟领导商量商量，这玩意现在花不了几个钱，一直在用WF 3530光分2400dpi去年买只花了$一百多。
数据中心见到过有人用Montage做特大图拼接的，看起来不错

呃……主要是用来扫描电路板的。这台扫描仪可以扫描有厚度的物体吗？

是个多功能打印机，扫描可以不盖盖子。商业产品在这里不多讲了，国内似乎也没见到有卖的，就是举个例子现在好用的扫描仪也不值几个钱。
