While the solver runs, examine the following illustration to learn about
the points you just loaded and why they were chosen to improve the
solution.
In general, having a diversity of points, such as points far and near the
camera, is critical to helping the solver.
4 When the solver finishes, solution_rf1 appears in the solution list. Check
the Overall Pixel Slip in the Solve control panel. It reads about 0.322, so
the new points have made an improvement.
If you have a larger Overall Pixel Slip, the problem may be that initial1
was selected when you solved again. Try selecting solution_rf instead and
clicking Solve again. The solution you have selected when you click Solve
can affect the outcome of the solver.
5 Play the animation and watch in the perspective view.
In this case, viewing from below the grid is best because the locators and
camera are below the grid in this solution. You must ignore where Live
has placed the camera and locators relative to the perspective grid.
Only look at the arrangement of the locators and the movement of the
camera. They should resemble the arrangement of points and the camera
motion as seen in the shot. For example, notice the points along the
fence are aligned along a plane, just as they are in the shot.
If you compare frames 80 and 180, youll see that the camera now moves
downward relative to the locators. This movement is what you would
expect the camera to do for this shot.
