FreeGaussian now processes raw DJI Osmo 360 .OSV files natively, building a level, real world scale gaussian splat and 3D mesh from the camera's original fisheye images.
The Osmo 360 joins the native fisheye pipeline that FreeGaussian opened to raw Insta360 .insv files in October for the X5 and X6. The other route for Osmo 360 footage is an equirectangular .mp4 exported from DJI Mimo or DJI Studio, a stitched panorama with a 2 to 1 aspect ratio that carries artifacts along the seam between the lenses and yields a mesh that has to be scaled and leveled by hand.
Each .OSV keeps the two lenses as separate square fisheye videos, along with motion data the camera always records. FreeGaussian reconstructs from the unstitched fisheye views and uses the IMU to recover gravity and true scale, so floors come out flat, walls vertical, and one meter in the scene matches one meter on site. In FreeGaussian's tests against measured markers, scale from 8K 30 fps video came within half a percent. The company still advises checking a known distance in the viewer for survey grade work.
Users select DJI Osmo 360 on the upload page, and FreeGaussian checks the file before upload, flagging exports and ordinary video. FreeGaussian tunes the pipeline on 8K at 30 fps and advises against timelapse, which stores motion data too rarely and produces a scene that is level but not at real world scale. Raw .OSV files run about 1 GB per minute. Because the output is metric, the measuring tool FreeGaussian added to its viewer in October reports meters directly, and the mesh drops into Blender, a game engine, MuJoCo or NVIDIA Isaac Sim without rescaling.
The Antigravity A1 drone joined the same pipeline on October 25 with native support for its raw .insv files. The A1 records two 3840×3840 fisheye streams at 29.97 fps from lenses that point up and down, sit about 67 mm apart and each see about 200°, and FreeGaussian calibrated the rig itself on a target board. The sensor reads its rows over about 21 ms, so the pipeline corrects rolling shutter with the gyroscope, and camera poses come from structure from motion guided by visual odometry, the IMU and loop closure.
Both cameras go through the native pipeline on free and paid plans. Free uploads are shared with FreeGaussian, which may feature them, while paid scenes stay with their owners. Other DJI cameras can still upload a stitched equirectangular .mp4. FreeGaussian is a project of OVER the Reality.
Osmo 360 .OSV processing is available now.
