This book provides step-by-step instructions on performing specific tasks using boujou. This book describes the features and functionality available in boujou . When it worked, it worked well, and when it didn’t, it was often easier to move to a manual solution. As the versions have progressed, boujou. Throughout this boujou tutorial, we’ll take our first steps into the program. Software required: Boujou 5, Maya , NUKE 7.

So I’ll give it a crack and see what I can do. This is the starting point for creating your own camera views. If you have the Optimize Focal Length button in the model tracking sidebar pressed then boujou will adjust the focal length value as you add springs.

No manual tracking required, saving you time and resources. Initialize solve — set the focal length to 23mm Once the model has been imported you can initialize the solve key schedule.

You can also use the solve key schedule to tell you the best frames for adding locator keyframes on, which takes a lot of the guesswork out of using survey data. Become a Redditor and subscribe to one of thousands of communities. The Pattern Matching Tracker in boujou has been completely rewritten so it provides a faster workflow. Boujou A simple Object Tracking shot turns into a nightmare self. For example, cameras can now be generated in a large variety of ways including?

If you have the optimize focal length option switched on then the focal length will also be adjusted to match the model alignment. Even a very simple model can be used for face-based tracking.

With each version of boujou I’m finding fewer reasons to have to go to external tools, and boujou 5 is no exception. Face-based tracking Face-based tracking links the feature tracks and the polygon faces in the model to calculate the camera amnual. Notice that the text under the frame counter in the main image window says User Solve [Aligned] and the model still appears to be in the right position. This will calculate the solve key schedule.

Skip bouhou main content. The Advanced solve refinement section allows you to optimize the camera path smoothness or correct for radial lens distortion as part of the solving process. Now it still has that basic functionality, but it’s been expanded with a lot more depth. Auto- Dense point cloud to get a better track, using the user track to kill non-consistent tracks. Optimize View — optimizes the camera position and orientation in the current frame by minimising the error between the measured features and the 3D predictions.

These breaks are called solve keyframes and their distribution is called the key schedule. Solve from Existing Cameras will take this camera path as a starting point and then refine it.

The 3D points used can either be from manual tracks locators and target tracks or from those automatic tracks that have had 3D points generated. Typing in the coordinates and linking them to locators was a time-consuming process and it was easy to make mistakes.

Masks with holes Orthographic views. I know this isn’t exactly what you asked for but it is possible I can’t just guide you, button by button, but lead you with ideas You have the option of deleting all existing solves when you run complete camera solving, or you can keep them in your project for reference or backup.

The end result is not perfect but it is very close and you can continue making refinements in the usual way.

Align the model so that it matches the car in the sequence as closely as possible. A lot of what has been added into boujou 5, such as the Graph Editor and improved Target Tracker, are features that some of the more target track-driven software already had. In boujou three you were able to input survey data and use it to improve the 3D structure of your camera solve. Vertex alignment manuaal a method of approximating the position of the camera.

The Graph Editor bojou the user to manually tweak the camera data and, if necessary, manuall. Create the second mask which boujuo be the hole 3. When boujou calculated the key schedule it made sure that there would be enough feature tracks linking each pair of keyframes to allow it to work out how the camera moved between them.

Create User Solve — this will create a solve that contains no camera views or structure. As the versions have progressed, boujou has added more and more functionality, giving users the means for increased refinements.

Default View from Known 3D — creates a new camera view goujou on the coordinate frame of the imported model. VICON uses cookies to make the site simpler.

However, you can now link the locators to the model vertices, which makes setting up your scene far more straightforward. Matchmoving Enters its Maturity David Sudd takes us through Vicon’s latest version of boujou to see how it tracks. When it worked, it worked well, and when it didn’t, it was often easier to move to a manual solution. Correct the alignment of the model and then continue the tracking. The reprojection error for a point in a frame is the distance between the position of the track in that frame and the position of the tracks 3D point projected into the frame using the cameras parameters on that frame.

mwnual If the key schedule is very sparse then certain sections of the shot may have very few 3D predictions, even though they seem to lots of feature tracks. Advanced users can do a lot more with it and take shots further than ever before without moving to a separate package. Just a quick question to get the best track I can It is now possible to bring in your survey data as an OBJ model and then connect the vertices interactively. Feature tracks that span less than 3 keyframes will be discarded.
