Our main course content this week is to learn 3D tracking. I used the basement footage as an practice.
In this process, I did a lot of tests. Because the results obtained at the beginning are always bad. The camera always deflects or slides when checking through the card and anchor point at the end.

After the calculation is completed, we need to try to stabilize the error value at about 0.5. This is more conducive to help us get an accurate camera movement trajectory.
