homography

Calculates the 3x3 homography matrix from a given set of corresponding point pairs to transform between two points of view.

Please use clang-tidy if you want to contribute: easy installation

Dependencies:

• Eigen 3.3

Features

• calculate the 3x3 homography matrix useing different solver for linear Ax=b Problems provided by Eigen
• Calculates the ''exact'' homography matrix when given 4 pairs of points
• Estimates the homography matrix if given more than 4 pairs of points e.g. if the points on one plane are measurements with noise.
• example usage is provided in include/homography/homography.hpp

Installation

• Install Eigen
• If you use CMake to build your project place this repro inside 'path' and use add_subdirectory(path/ homography) and target_link_libraries(your_lib homography_lib)
• Or just include the header

Example

• You kan find an simple example in example.cpp.
• build it: ´g++ -std=c++17 example.cpp -o example_executable´
• (if you use a c++ version prior to 17, thats ok, but there will be some warnings.)
