[3D_Vision_Tutorial] Ubuntu 20.04 + OpenCV + Ceres Solver install - [1]

- https://github.com/mint-lab/3dv_tutorial : 3dvision tutorial code

- Dependency : OpenCV / Ceres Solver

 

🐱 OpenCV Install

$ pkg-config --modversion opencv # OpenCV 가 이미 깔려있는지 확인하기
$ pkg-config --modversion opencv4 # version 4 부터는 이렇게 확인해야한다.

- Install 참고 https://webnautes.tistory.com/1186

접근 1 ) USE_CUDA 활성

https://github.com/ceres-solver/ceres-solver/blob/master/CMakeLists.txt -> USE_CUDA 설정이 필요하다

접근 2 ) wget으로 다운받아서 설치 (clone으로 한 파일 말고 wget으로 다운받아서 설치하니 된다,,ㅎ,,)

⚠ Ceres-solver install error 2

-- Install configuration: "Release"
CMake Error at cmake_install.cmake:41 (file):
  file cannot create directory: /usr/local/lib/cmake/Ceres.  Maybe need
  administrative privileges.

-> make install 은 sudo를 붙이자 따로 cmake 때 INSTALL_PREFIX 경로를 지정한 것이 아니라면
