我已经安装了 OpenCV-3.0.0 并配置了 BUILD_EXTRA_MODULES 以启用对 SIFT 和 SURF 算法的访问。我想在两个简单地相互旋转一点点的 jpeg 图像上运行拼接示例。这些图像是我自己的，而不是任何标准图像（我在哪里可以找到这些标准拼接示例图像，如果有的话？）然后我继续执行
./cpp-example-stitching_detailed source_image1.jpg source_image2.jpg
我收到以下错误：
OpenCV Error: Assertion failed (timelapse) in main, file /path/to/opencv-3.0.0/samples/cpp/stitching_detailed.cpp, line 818
terminate called after throwing an instance of 'cv::Exception'
what(): /path/to/opencv-3.0.0/samples/cpp/stitching_detailed.cpp:818:
error: (-215) timelapse in function main
Aborted (core dumped)
当我尝试更简单并执行简单的 ./cpp-example-stitching 可执行文件时，如下所示：
./cpp-example-stitching source_image1.jpg source_image2.jpg
那么输出错误是
pure virtual method called
terminate called without an active exception
Aborted (core dumped)
如果它有任何用途，以下是运行 opencv_test_stitching 和 opencv_perf_stitching 的结果
