Usage
General overview
If you want to track 3D position of real object using this addon, you need:
- Capture video of this object from 2 static cameras. Cameras have too be located in different positions, with angle 30-60 degree, be close as posible to object and contain object for all moving time.
- Measure real position and rotation of cameras
- Process vide footage, increase contrast and sharpness
- Track 2D motion of object on 2 videos using Blender Movie tracking
- Recreate 3D scene with 2 cameras using measured data
- Setup addons parameters, Field of View cameras, Frames Per Second
- Process addon tracking. Position animation will be applied to object
