Week 4|3D Tracking

We need to recreate the camera and match the camera movement for 3D tracking.

Room Tracking

We denoise the plate firstly and use grade node to make it easier for nuke to track every point in the plate. We may need to roto out some elements which are affected by other factors apart from camera movement.

cameraTracker

Use camera tracker to track the plate. We need to track first and solve next. Adjust some parameters can reject the points with larger errors.

Remember to set ground points beforehand in CameraTracker node.

Use point cloud to accurately position the asset in the 3D scene, for example, the cards.

Point Cloud

Position the cones and cards in the plate. Select particular tracked point in the plate and left click to choose creating the axis, we can link these axis with the suitable geometries such as cones.
