How to run the CYLINDER mode

[tianboguangding]

hi, thanks for your shared panarama-stitching

when I run the image-stitching as followed:

wqy@wqy-Precision-T3600:~/Desktop/panorama-master/src$ ./image-stitching ../data/apartment/small-01.jpg ../data/apartment/small-02.jpg [init_config@main.cc:271] Run with camera estimation mode. sh: 1: convert: not found sh: 1: gm: not found sh: 1: convert: not found sh: 1: gm: not found sh: 1: convert: not found sh: 1: gm: not found

[CImg] * CImgIOException * [instance(0,0,0,0,(nil),non-shared)] CImg::load(): Failed to recognize format of file '../data/apartment/small-01.jpg'. terminate called after throwing an instance of 'cimg_library::CImgIOException' what(): [instance(0,0,0,0,(nil),non-shared)] CImg::load(): Failed to recognize format of file '../data/apartment/small-01.jpg'. Aborted (core dumped)

So how do I use it? Thanks very much!

To read jpeg file you need to install libjpeg-dev (name may be different on different platforms).

[tianboguangding]

I have installed the libjpeg-dev, bue the same question is occurred

[ppwwyyxx]

It's my fault. The latest commit should fix this. Install imagemagick can also solve your problem.

Thanks !It worked . Sorry,but one more question, How to switch the different mode in the config.cfg? For example :the occurred global playground Image

[ppwwyyxx]

Just set one of 'CYLINDER', 'ESTIMATE_CAMERA', 'TRANS' to 1 in config.cfg and run the program.

Q1:No matter which mode was set to one , the running result of your apartment images is rectangle all the time,but not spherical(circular image)?

Q2:And when I test myself's pictures(only two 490*653 images),error is as followed: error: Result too large. Something must be wrong!

Thanks!

The mode is for different kind of algorithm. The spherical example is not a mode, just something fun. And it's easy to convert the 360 degree rectangle panorama to a spherical one.

It's likely that your images doesn't overlap enough (you can look at the example images to see what kind of overlap is needed). You can also post your log here.

Thanks very much! i Compiled your project successfully in vs 2015y，but could not run it； the error log of running is as followed:

it seems the same error with the linux's. After i installed the window's version of imagemagick (ImageMagick-6.9.3-8-Q8-x64-dll.exe), set the path of include/lib/dll ,but ... the error log of running is below:

Seems like you're not compiling with the latest commit 877327042a8729498188e0d494d17b8546a3f72f? convert or gm will only be used when CImg cannot use libjpeg.

Also it could be easier if you just use png files. png reader/writer are already included in the project.

Thanks for your reply! But After plus the #define cim_use_jpeg in the .c file (imgio.cc), the project even can not to be compilied successfully ! And the errors error of compiling is as followed：

....... 1>jpeg.lib(jerror.obj) : error LNK2001: unresolved external symbol __imp___iob_func 1>D:\github\panorama\1\panorama-master\src\build\Debug\image_stitching.exe : fatal error LNK1120: 1 unresolved externals ========== Build: 0 succeeded, 1 failed, 1 up-to-date, 0 skipped ==========

The used jpeg version is jpeg-9a. Link->Input->Additional Dependencies : D:\jpeg-9a\x64\Debug\jpeg.lib

[ppwwyyxx]

That looks like a problem with your jpeg library. Unfortunately I've no idea where to find a jpeg library for windows.

Some google search suggest the reason is that your jpeg library is probably built with an old version of visual studio: http://stackoverflow.com/questions/30412951/unresolved-external-symbol-imp-fprintf-and-imp-iob-func-sdl2

Thanks for your help! Now it worked!

Have you considered a parallel algorithm(eg:cuda for sift) of stitching img in order to improve the speed?

[ppwwyyxx]

Right now it is parallel across the images in most steps. Cuda will definitely make it faster but I won't have time for that in the near future.

Thanks for your reply :)
