I started this practice with having some Tracking points set on some graffiti and upping the contrast to get a better tracking pattern and an easier track around the graffiti on the wall.
After this i went about making more points and tracking these points on the floor to get an accurate enough 3d space to track in, though these points are not always in frame and sometimes needed to be ended early, they did end up getting me the result that i needed by giving me a better outcome in the end after some tweaking, as the track point 45, being the closest to the camera went out of frame very easily in the first bit of the video and had to be ended early.
Next I went about tracking the back watergate and side block of concrete, which required a lot of zooming in and changing of the viewing options to up the contrast and brightness to get a proper track that would stay locked on and wouldn’t jump around so wildly, as in the original video this area is very dark and doesn’t have a lot of distinct patterns to track and only when upping the brightness can you get things like the corners of where beams meet or where the gate meets the wall.
After struggling to get tracks on that portion, the next portion was fairly easy as with a bit of upping the contrast, there were a lot of creases or crevices in the wall that could be tracked fairly nicely.
After that I went about tracking the back wall which was a bit difficult at first due to a lot of the points consistently going in and out of the frame and having to end and restart the track constantly, but after tracking the front area with things on the ground i was used to this by now.
After this it was a matter of adding the camera distortion to the image and calculating with quartic distortion.
Originally the points on these were way off and the groundplane seemed really off, this was because at some point in my tracking i’d accidentally set my distortion for my viewport at a high setting. After resetting it i could see the difference in where the points were.
After fixing the distortion isssue i recalculated and managed to get a better track by blending or triangulating certain tracking points and even deleting some to get less deviation between points.
After this I decided to test out the 3DE 3d camera and put a simple cube into the scene just by translating the x coordinates of the cube over and fitting it near a point just to make sure it looked fine on the track and wasn’t bouncing around too much.
After this it was a matter of testing it out in Maya just to make sure that if i wanted to put any more complex 3D objects n that it wouldn’t be an issue. I Imported it into Maya and with Maya being itself, it immediately crashed. Though after a second import it was working fine and was imported properly.
This was the final track I managed to get on the video and import into Maya.
