不安装cygwin而只在windows下运行bundler

时间：2023-02-02 00:18:20

bundler是个挺强大的三维重建库，具体的就不介绍了，上其主页上看去。

这里主要记录一下怎么在windows下运行这东西。网上搜索的都要安装cygwin，但这东西太大了，安装下来1个G以上。空间宝贵，故想不安装它直接在windows下跑。

借助了opencv和Qt，其中opencv是用来将.jpg图像转换成.pgm格式的，因为bunder其中用到的特征检测siftWin32只能用P5开头的.pgm格式的图像；而Qt是用来遍历文件夹下的图像路径的，这个如果熟悉其它如MFC的也可以用其它的代替，反正只要能运行就Ok了是吧。

话不多说，上代码。

换种说法，就是：
 

Windows下调用bundler(有点麻烦，建议写个脚本或程序衔接中间的参数变换什么的)


 bundler.exe list.txt --options_file options.txt


 其中参数2是图像名称列表，参数4是配置信息（主要包括匹配点文件名matches.init.txt[由KeyMatchFull.exe生成]及其路径）


 KeyMatchFull.exe list_keys.txt matches.init.txt


 其中参数1是特征点的文件列表，特征点文件（xx.key）由siftWin32.exe生成，参数2是输出文件


 siftWin32.exe <xx1.pgm >xx1.key
 其中参数2和3是图像名称（貌似涉及到pgm和jpg等的转换）这些.key文件需要在KeyMatchFull.exe的参数1中罗列


 --------------------------------------------------------------------------
 list.txt 文件样例


 ../mytest/test0000.jpg
 ../mytest/test0001.jpg
 ../mytest/test0002.jpg
 ../mytest/test0003.jpg
 ../mytest/test0004.jpg
 ../mytest/test0005.jpg


 --------------------------------------------------------------------------
 options.txt 文件样例（主要修改第一行第二个参数，其它可以不改）


 --match_table ../result/matches.init.txt
 --output bundle.out
 --output_all bundle_
 --output_dir bundle
 --variable_focal_length
 --use_focal_estimate
 --constrain_focal
 --constrain_focal_weight 0.0001
 --estimate_distortion
 --run_bundle




 --------------------------------------------------------------------------
 list_keys.txt 文件样例


 ../mytest/test0000.key
 ../mytest/test0001.key
 ../mytest/test0002.key
 ../mytest/test0003.key
 ../mytest/test0004.key
 ../mytest/test0005.key
