OC-GS: Gaussian Splatting for Irregular Turntable Capture
OC-GS refines per-image angles in a shared orbit model to reconstruct objects from sparse, irregular turntable views.
OC-GS is an object-centric Gaussian splatting method that jointly refines each image's rotation angle while sharing the camera, rotation axis, and pivot. On rendered objects with 12, 8, and 6 irregular views, mean foreground PSNR was 21.26, 19.36, and 15.83 dB, beating four pose-free Gaussian splatting baselines. Refining image-estimated angles improved mean foreground PSNR by 7.88 dB versus fixed estimates, and real captures gained 0.70 dB.
- Mean foreground PSNR is 21.26, 19.36, and 15.83 dB at 12, 8, and 6 views.
- Refining estimated angles gains 7.88 dB versus keeping those angles fixed.
- Image-derived initialization and the shared motion model both help.
- Real turntable captures gain 0.70 dB mean foreground PSNR.

1 min read at arxiv.orgUneven rotation and dropped frames make equal-angle assumptions unreliable for turntable reconstruction. We present OC-GS, an object-centric Gaussian splatting that refines each image's angle while maintaining a shared camera, rotation axis, and pivot. This orbit-consistent refinement jointly optimizes image-derived geometry and angles to reconstruct objects from sparse, irregular captures.
