[Bf-committers] GSoC 2017: Camera breathing support

[Tianwei Shen]

Hi Everyone,

Last summer I participated in GSoC 2016 and worked on the multi-view camera reconstruction project. Some of my efforts are summarized in this blog: http://hlzz.github.io/blender3/ <http://hlzz.github.io/blender3/>. And this patch (https://developer.blender.org/D2187 <https://developer.blender.org/D2187>) is now being reviewed and revised. This year I would like to apply again and work on the camera breathing support, which is already requested by some users during the time I worked on the motion tracking project. Now I need clarifications for some specific problems. 

1. should we automatic detect the changes of focal lengths, or is it specified by users as additional inputs (like the focal length for each frame)? I know we can read exif tags to get focal lengths for photos. Do we have a similar approach for videos?

2. Is the current UI able to handle camera breathing, if we need additional inputs from users?

I think this project also has something to do with my revisions done on the motion tracking system last summer. Hopefully I should be able to merge the revisions and move towards the goal of automatic tracking.


Thanks,
Tianwei
