Surely it could be used as an extra constraint when inferring camera poses - you know the camera can only move in certain ways from one frame to the next?)
Can I ask why you say this? Camera motion models including Kalman filters of various kinds and constraints on derivatives etc, are absolutely used in SLAM and photogrammetry afaik, and have been for a long time.
- andybak 3y agoOK maybe it's my limited experience but last time i tried it, video was treated as "extract frames and then only use every 50th (or so)" This was a couple of years ago probably. Meshroom and Reality Capture. Maybe I was mistaken or maybe they've improved? Can you point me to software that does use video for photogrammetry in the way you describe?
