    • We tested four state-of-the-art methods and ours on 42 sets of images in same setting (grid size, feature points and parameters).

Usage

  1. Download code and compile.

    • You need Eigen, VLFeat, OpenCV 3.0.0 and OpenMP (if you don't need to use omp.h, you can ignore it.)
    • My GCCVRSION is Apple LLVM 6.0 ``` GCCCLANGUAGESTANDARD = GNU99 [-std=gnu99] CLANGCXXLANGUAGESTANDARD = GNU++14 [-std=gnu++14] CLANGCXX_LIBRARY = libc++ (LLVM C++ standard library with C++11 support) ```
    • My Eigen version is 3.2.7 (development branch). You need to make sure you can use "LeastSquaresConjugateGradient" class.
  2. Download input-42-data.

    • 42 sets of images: 6 from [1], 3 from [2], 3 from [3], 7 from [4], 4 from [5] and 19 collected by ourselves.
  3. Move [input-42-data] folder to your working directory.

  4. Run the command:

    ./exe folder_name_in_[input-42-data]_folder
    

    The results can be found in [0_results] folder under [input-42-data] folder.

  5. Optional:

    • You can control the parameters in Configure.h or xxx-STITCH-GRAPH.txt

Results

More natural:

AutoStitch Ours Ours(border)
AutoStitch AANAP Ours
AutoStitch AANAP
Ours(2D) Ours(3D)

Stitching of 20 images:

AANAP Ours

Stitching of 35 images:

AANAP Ours(2D) Ours(3D)

Our method can be used to empower other methods with APAP’s alignment capability:

AutoStitch AutoStitch + Ours Ours

Debug mode

You can disable debug mode by adding NDEBUG macro. Otherwise you will see the intermediate which is located in the [1_debugs] folder under [input-42-data]. You can download all intermediate data. The intermediate example:

Border Mesh
Initial Features After sRANSAC
Line Data 1 Line Data 2

Speed

If you want to speed up, MATLAB solver is significantly faster than Eigen.
