project #3: MatchMoveAssigned: 2009/04/23Due: 2009/05/13 11:59pm submission, voting, artifacts, winning artifacts Project descriptionMatchmove is a technique of estimating camera parameters from an input video sequence so that computer generated imagery (CGI) could be seamlessly inserted into the sequence. In this project, you will use tools to create visual effects using matchmove. You can either use camera calibration techniques or structure from motion methods. Essentially, for this project, you have to do the following things:
Taking videoWe will provide a camera for the students with no access to video camera. Please sign up here to borrow the camera.MatchMove and renderingIf you prefer to use calibration approaches, you can either Bouget's matlab calibration toolbox or Zhengyoun Zhang's calibration program. However, to use this approach, you have to figure out how to insert CGI by yourself.For structure from motion, there are many excellent commercial software. However, most of them are very expensive (around $5,000) which we can't afford to use in this class. Hence, we will use icarus, the predecessor of PFTrack, for this project. You can download icarus here. Please note that icarus is not distributed online any more. Hence, don't distribute it and only use it for academic usage. The other viable option is Voodoo. This one is free and could be used along with blender as weel. For inserting CGIs, we recommend that you use Blender 3D to add CGI. Here is a wondeful tutorial on using icarus and Blender for the complete MatchMove process. You will need this Python script to import Icarus output to Blender. Here are the slides from TA's help session. SubmissionYou have to turn in two videos, the raw footage before inserting CGI and the final composite video as your artifacts. It is not required but preferred to Write a simple report in html describing what tools you have used and what lessones you have learned. Submit your videos through the submission website. |
