A pan shot 3d camera tracking best method (shot taken from Samsung A52 smartphone with wide angle camera)
Hi i am new to 3d camera tracking world. have spent days trying to understand the technical concepts of camera like focal length, aperture, lens size, optical center etc. so there is a pan shot i shot wih locked focus and locked exposure in 4k 30 fps. then i tried using after effects camera traking, blender camera tracking, using COLMAP photogramettery point cloud AND the animated camera path. each one of them have problems.
at first ae tracker is does track te fooage but with no depth so the solve error remains pto 4 px. pretty ok still camera in ae jitters, lags, slides.
blender tracker is trash loke absolute crap.
then i tried COLMAP photogrammetry sokution. problem is that instead of rotating the camer from the pivot point, it aimated the camers to follow a huge path which has got many orientation problems like coordination scaling issue. because when i place 3d object into the scene, the 3d object slides and PANS more then the real life camera. and because of lack of depth, the colmap actully created a panoramic 2.5 D point cloud instead of properly constructing a whole photogammetry 3d scene. so essentially alignments are imperfect in colmap.
so i need a perfect workflow. i even tried to scale down the point cloud to match the coordinate system perfectly. actually i used real life measurements like the distance form camera to the green belt, road width, distance from gorund to camera. but still the 3d objects seem to be sliding and panning more than the camera even tho the points form the point cloud is exactly sticked to their respective positions throughout the entore scene. can you pelase suggest any better workflow? should i use Nuke 3d camera tracker? i basically need to attach teh car 3d model (park) on the green belt)
