Lab 3 - 7 Rules of Matchmove

Q3 : 7 Rules of Matchmove

Rule 1 : There has to be something to track

For rule 1, in order to matchmove there must be something to track.

Rule 2 : We have to track things at different depths

For rule 2, in order to have a good matchmove we must have different depths.

Perspective will become clearer if things are place in different depths.

Rule 3 : We have to get Helper Frames

With rule 3, it will help the computer to see better.

Take at least 10 different pictures in different angles.

Rule 4 : A little bit of foreground makes a better matchmove

For rule 3, in order to have a better matchmove we should add in some foreground.

Things that is place nearer to the cam is 100x bigger.

Foreground reveal cam position more accurately than anything else.

Rule 5 : We cant track anything that moves

Every things must be static. Everything that move need to be mask out.

Rule 6 : You cant have too much foreground

We lose all the markers if there is too much foreground.

Too much foreground will wash out everything we are tracking.

Rule 7 : You have to get a Scale Reference

Measure distance between 2 points that we want it to be track.

With this 7 rules apply, if will contribute to a successful match moving.
