AnyCalib — Full-Resolution Camera Calibration

Single-image camera calibration and lens distortion correction.

No quantization, no resolution limits — full FP32 inference with the complete AnyCalib pipeline. Automatically uses GPU when available (ZeroGPU / dedicated), falls back to CPU.

What it does

1. Upload any image (phone photo, action cam, drone, dashcam, etc.)
2. DINOv2 ViT-L/14 backbone predicts per-pixel ray directions
3. RANSAC + Gauss-Newton calibrator fits camera intrinsics
4. Image is undistorted at original resolution using the fitted parameters

Output

• Corrected image at full input resolution
• Camera intrinsics: focal length, principal point, distortion k1
• FOV (horizontal and vertical)
• Distortion type (barrel, pincushion, or negligible)
• Raw JSON with all parameters, timing, and metadata

Model

• Architecture: DINOv2 ViT-L/14 (304M) + LightDPT (15.2M) + ConvexTangentDecoder (0.6M)
• Total: ~320M parameters, full FP32
• Weights: SebRincon/anycalib
• ONNX: SebRincon/anycalib-onnx
