如果仅仅是简单的拼接，可以采用stitching.cpp就差不多了；但是如果采用stitching_detailed.cpp的话，首先要解决的就是"编译问题",而后解决的是分析不同参数下的拼接结果和匹配效果；最后是能够理解一些原理。

     OK,历经一些调试，编译成功，首先看一下有哪些参数可以调整。其实光靠这个就可以写一个简单的带调整的界面了。

F:\06.项目项目\opencv拼接\imageStitching\imageStitching>imageStitching.exe Rotation model images stitcher. stitching_detailed img1 img2 [...imgN] [flags] Flags:   --preview       Run stitching in the preview mode. Works faster than usual mode,       but output image will have lower resolution.   --try_gpu (yes|no)       Try to use GPU. The default value is 'no'. All default values       are for CPU mode.

Motion Estimation Flags:   --work_megapix <float>       Resolution for image registration step. The default is 0.6 Mpx.   --features (surf|orb)       Type of features used for images matching. The default is surf.   --match_conf <float>       Confidence for feature matching step. The default is 0.65 for surf and 0.3 for orb.  这个我可能会单独配置   --conf_thresh <float>       Threshold for two images are from the same panorama confidence.       The default is 1.0.   --ba (reproj|ray)       Bundle adjustment cost function. The default is ray.   --ba_refine_mask (mask)       Set refinement mask for bundle adjustment. It looks like 'x_xxx',       where 'x' means refine respective parameter and '_' means don't       refine one, and has the following format:       <fx><skew><ppx><aspect><ppy>. The default mask is 'xxxxx'. If bundle       adjustment doesn't support estimation of selected parameter then       the respective flag is ignored.   --wave_correct (no|horiz|vert)       Perform wave effect correction. The default is 'horiz'.   --save_graph <file_name>       Save matches graph represented in DOT language to <file_name> file.       Labels description: Nm is number of matches, Ni is number of inliers,       C is confidence. Compositing Flags:   --warp (plane|cylindrical|spherical|fisheye|stereographic|compressedPlaneA2B1| compressedPlaneA1.5B1|compressedPlanePortraitA2B1|compressedPlanePortraitA1.5B1| paniniA2B1|paniniA1.5B1|paniniPortraitA2B1|paniniPortraitA1.5B1|mercator|transve rseMercator)       Warp surface type. The default is 'spherical'.   --seam_megapix <float>       Resolution for seam estimation step. The default is 0.1 Mpx.   --seam (no|voronoi|gc_color|gc_colorgrad)       Seam estimation method. The default is 'gc_color'.   --compose_megapix <float>       Resolution for compositing step. Use -1 for original resolution.       The default is -1.   --expos_comp (no|gain|gain_blocks)       Exposure compensation method. The default is 'gain_blocks'.   --blend (no|feather|multiband)       Blending method. The default is 'multiband'.   --blend_strength <float>       Blending strength from [0,100] range. The default is 5.   --output <result_img>       The default is 'result.jpg'. 测试图片：

第一组：

--全部默认参数,80秒，结果

--preview 约80秒,这个图片拼接的不错，但是时间太长了。

        --features (surf|orb) 改成orb后速度显著提升

  --match_conf <float>也应该是数值越小匹配越快，但是失败的可能也越大。这个是不断调整参数的过程。

   --ba (reproj|ray)默认是ray，改为reproj后，速度更快！更快

然后，就是   --warp  这一块，参数比较多

plane

cylindrical

fisheye

spherical
