=Google summer of code: Camera tracking integration =

==General info==

NOTE: Google Summer of Code program was finished and camera tracking project was merged into trunk. Information here might be outdated, more recent information can be found [[Doc:2.6/Manual/Motion_Tracking|here]]

This is homepage of my Google Summer of Code project called "Camera tracking integration into Blender".

Here are some links to pages with more detailed info:
* [[User:Nazg-gul/GSoC-2011/Proposal|Proposal]]
* [[User:Nazg-gul/GSoC-2011/FAQ|Frequently Asked Questions]]
* [[User:Nazg-gul/GSoC-2011/WeeklyProgress|Weekly progress reports]]

==Current workflow state==
* {{done||}} Load image data - video or sequence of images.
* {{done||}} [Optional] Input known camera parameters.
* {{done||}} [Optional] Provide hints to camera lens undistortion solver (identify straight lines in the image) to help with undistorting the image.
* {{todo||}} [Optional] Undistort the camera lens using a distortion solver.
* {{todo||}} [Optional] Create mask for data you don't want tracked.
* {{todo||}} [Optional] adjust color/contrast/etc so that feature points to track have increased contrast and are thus easier for the tracker to find them.
* {{done|}} [Optional] select specific features you want tracked (either by mask or placement of tracking points). (there's feature selection, but no masks)
* {{done||}} If you specified specific features to the tracker you may also want to specify how the points should be tracked (bounding box for the tracker to look for the point in; whether the object being tracked is.
* {{todo||}} «Rigid» or can deform, and knowledge of the types of camera/object motion - object translation; rotation; camera translation; rotation).
* {{done||}}Send image data, specified track data; camera data; and mask data to tracker.
* {{done||}} Tracker library can automatically identify feature points to track and or use user specified features, ignoring areas that are masked (no masks support yet).
* {{done||}} Do a «solve» of the camera motion based on the track points, including statistics on how 'good' the tracks are in contributing to the solve.
* {{done||}} Return track point data and camera solve to software, including the statistical analysis of the track points.
* {{done||}}Based on the statistical analysis pick error thresholds for what track points to automatically delete.
* {{done||}} [Optional] Manually delete any track points.
* {{todo||}} [Optional] Create a mask to 'hide' unwanted track points.
* {{todo||}} [Optional] Mask can be assigned to follow a set of track points to automatically mask a moving object from the tracker/solver.
* {{todo||}} [Optional] mask can be manually keyframed so that it moves and deforms over time to mask a moving object from the tracker/solver.
* {{todo||}} [Optional] Provide a manually created camera curve to 'hint' the tracker/solver what you expect the actual curve to look like.
* {{done||}} Retrack if additional tracker points are now needed.
* {{done||}} Pass the tracker points, camera hints, etc. to the camera solver.
* {{done||}} Return the solved camera track and the 3d location of the track points to the software.
* {{done||}} Visualize the camera motion and track points in the 3d view.
* {{done||}} Define a ground plane reference to the 3d track points and camera.
* {{done||}} Define the scene origin relative to the 3d track points and camera.
* {{done||}} Define the world scale and orientation relative to the 3d track points and data.
* {{done||}} Add a test object into the 3d view and see if it stays in the proper location.
* {{todo||}} [Optional] Stabilize the camera view based on the solved camera track.
* {{todo||}} [Optional] smooth the camera track curve.
