Introduction

THIS PROJECT IS MOVED TO http://wiki.blender.org/index.php/BlenderDev/ReconstructionAndMotionTracking AND MANAGED BY Keir.

Two options to solve a match-move and a camera track:

  • A motion tracking to animate bodies or faces, set a interested points to track and asign to controls of blender.
  • An estimation of camera parameters and reconstructs a 3D scene. It useful to make postproduction and a model integration.

Project Goals

  • Make a good motion tracking
  • Interact with videos and cameras.
  • Insert/delete keys points.
  • Asign keys points to empties to animate anything.
  • Moving things that can be garbage matted (poly mask). Or detect this point with some optical flow algorithm.
  • More to define...

We have a first simple tracker. I paint over image editor the track points. 

ToDo:
* The points will store in permanent array data with ipo anim.
* Make a hide/show points with sima on drawimage.c
* After we cvCalcOpticalFlowPyrLK we need make a call to cvGoodFeaturesToTrack 
to find new points, we must remove the duplicate points
* more...

  • Look for best software to work
  • Look for doc and papers

2007/01/21

  • We go to use opencv and see the bazar tools
  • Use image editor to make the tracking interface

Personal Notes 

* Revisar Documentacion proyectiva 3d ...
* Find info about EGOMOTION
* don't forget to edit write.c/read.c to set the void* as NULL on fileload (to struct TrackData) Thanks Genscher
