结构(openCV)：“重构”未在此范围内声明

Question

我是opencv库的初学者。我在Ubuntu17.04上安装了它，安装过程中的一切都很完美，完全没有错误。我已经安装了opencv-母版，构建了它，然后我下载了opencv_cont排版-母版，一切都很完美。

我正在尝试使用SFM (用于运动的结构)构建scene_reconstruction。我已经安装了所有依赖项：

sudo apt-get install libeigen3-dev libgflags-dev libgoogle-glog-dev

然后我安装了Ceres Solver：

git clone https://ceres-solver.googlesource.com/ceres-solver
cd ceres-solver
mkdir build && cd build
cmake ..
make -j4
make test
sudo make install

一切都很好，一点错误也没有。我试着按照这里的正式文档( Reconstruct.cpp. ) (场景重建)编写example_sfm_scene_reconstruction.cpp

我编写了CMakeLists.txt文件：

cmake_minimum_required(VERSION 2.6 FATAL_ERROR)

project( Reconstruct )

include_directories( /usr/local/include/eigen3 )

find_package( OpenCV REQUIRED )
find_package( Eigen3 REQUIRED )
add_executable( Reconstruct Reconstruct.cpp )
target_link_libraries( Reconstruct ${OpenCV_LIBS})

我已经创建了构建目录并使用mkdir build && cd build打开了它。然后是cmake ..

但是，当我尝试执行make时，我有以下错误：

error: ‘reconstruct’ was not declared in this scope
 econstruct(images_paths, Rs_est, ts_est, K,
points3d_estimated,is_projective);

我试着跟踪这个论坛第476期，但是任何事情都对我有帮助。
