I need some help tracking a scene that looks like it should be really easy. My son and I took a DJI Phantom 3 and flew around an old train bridge. I wanted to import the footage into Blender, track it, put in a blender train and send it down the tracks. I thought this would be easy since the scene seems to have a lot of tracking points, good slow movement, lots of parallax movement, etc. After working for hours and hours on it though I’m starting to lose hope.
Can anyone offer some advice on how this type of scene can be tracked? I’ve uploaded the original movie to my google drive here: https://drive.google.com/open?id=0ByMMbmA9cIVvRlB6Ynk3bG9sN1U. It is a mp4 file around 50 MB, ~500 frames or so. The intial display of the movie is very low quality but if you download it is is full quality.
I looked around for the camera specs on a DJI Phantom and put those into Blender and the solution actually got worse. It has a 1/2.3" sensor and 20mm focal length with a 94 degree FOV (info gathered from here). When I try and track it, Blender can’t find the perspective at all and when I try and set up the scene in the solution everything is all flipped around. I’ve tried setting the floor plane by selecting three points on the track, that didn’t work. I picked three points on the water below, that didn’t work. I tried setting the X-axis by picking a point along the track, that didn’t work. Obviously I don’t know what I’m doing.
Can anyone offer any advice in this situation? Thanks!
