# Birds Eye View / Homography using OpenCV

C & C++ Jul 18, 2015

When I looked for a small example for a homography transformation using  OpenCV in order to provide a birds eye projection of an image. I did not  find an appropriate ones, hence, I combined a number of motivating  introductions and code fragments in an illustrative small program. It  can be adapted for your actual purpose or just use to determine the  parameters of a perspective manually (for fast hacks :-), otherwise you  should prefer one of the traditional calibration methods).

Compile with:

\$ g++ example.cpp -o Example pkg-config --libs --cflags opencv -ldl
