This is a quick and easy implementation of a head pose estimator based on geometric model fitting via 2D-3D points correspondence. Results aren't that good, but for a 5 min work and practically no theoretical knowledge - they're pretty nice.

See the blogpost for more details and the code

  • If you consider the narrow range of your samples - having pitch yaw and roll pretty much constrained within 10 degrees - your error is pretty big.

  • can you explain the 3x3 rotation matrix?

    e.g. how do 9 discrete values translate into 3 values- pitch roll and yaw?

  • Looks like the results are just ok, especially in yaw (looking left to right) estimation
