camera_model

相机内参标定和双目标定

支持多种相机模型:

pinhole model
kannala-brandt model
mei model
scaramuzza model

支持多种标定板

chessboard
circles grid
asymmetric circles grid
aruco makers
charuco makrers

编译 & 安装

依赖项

OpenCV (with opencv_contrib)
Ceres Solver
boost

cd camera_model
mkdir build
cd build
cmake ..
make
sudo make install

调用

编译安装之后， camera_model会作为共享库被安装在系统目录, 使用时无需添加源码，只添加依赖关系即可

cmake_minimum_required(VERSION 3.0)
project(camera_model_example)

add_executable(example example.cc)
target_link_libraries(example camera_model)

用法

相机内参标定 intrinsic_calib

Use intrinsic_calib.cc to calibrate your camera.

双目标定 stereo_calib

Use stereo_calib.cc to calibrate your camera.

Undistortion:

See Camera.h for general interface:

liftProjective: Lift points from the image plane to the projective space.
spaceToPlane: Projects 3D points to the image plane (Pi function)

案例

相机内参标定 intrinsic calib

mei model

./intrinsic_calib -w 9 -h 6 -i ../data/fisheye -p left -e jpg --camera-model mei --camera-name fisheye_mei -v

pinhole model

./intrinsic_calib -w 9 -h 6 -i ../data/fisheye -p left -e jpg --camera-model pinhole --camera-name fisheye_pinhole -v

kannala-brandt

./intrinsic_calib -w 9 -h 6 -i ../data/fisheye -p left -e jpg --camera-model kannala-brandt --camera-name fisheye_kannala-brandt -v

scaramuzza

./intrinsic_calib -w 9 -h 6 -i ../data/fisheye -p left -e jpg --camera-model scaramuzza --camera-name fisheye_scaramuzza -v --view-results

asymmetric cirlces grid

./intrinsic_calib -w 4 -h 11 -i ../data/asymmetric_circles_grid -p asymmetric_circles_grid -e jpg --pattern asymmetric_circles_grid --camera-model pinhole --camera-name webcam -v --view-results

注意，这里一定要4x11, 设置为11x4就不行

circles grid

./intrinsic_calib -w 9 -h 6 -i ../data/circles_grid -p circles_grid -e jpg --pattern circles_grid --camera-model pinhole --camera-name circles_grid_cam -v --view-results

charuco marker

./intrinsic_calib -w 4 -h 6 -s 0.04 --marker-size 0.024 -i ../data/charuco -p charuco -e jpg --pattern charuco --dp ../data/pattern/detector_params.yml -d 10 --camera-model pinhole --camera-name charuco_cam -v --view-results

./intrinsic_calib -w 4 -h 6 -s 0.04 --marker-size 0.024 -i ../data/charuco -p charuco -e jpg --pattern charuco --dp ../data/pattern/detector_params.yml -d 10 --camera-model kannala-brandt --camera-name charuco_cam -v --view-results

stereo calibration

./stereo_calib -i ../data/stereo_images/ -e jpg --prefix-l left --prefix-r right --camera-model mei -v --view-results

stereo calibration circles (virtual test with mono image)

./stereo_calib -i ../data/circles_grid --pattern circles_grid -e jpg --prefix-l circles_grid --prefix-r circles_grid --camera-model mei -v --view-results

TODO

add aruco marker
