Recently, Google's deep learning team, in collaboration with researchers from several universities, announced a new system called 'MegaSaM.' This system can quickly and accurately estimate camera parameters and depth maps from regular dynamic videos. The advent of this technology will open up more possibilities for the videos we record in our daily lives, particularly in capturing and analyzing dynamic scenes. Traditional Structure from Motion (SfM) and monocular Simultaneous Localization and Mapping (SLAM) techniques.
