@jessev08

Hi, I’ve worked on projects like this before, so what you’re describing makes sense to me. And I'm really interested in this project - 3D reconstruction of camera rig with Colmap. I usually focus on getting things done cleanly and making sure they work properly in real use, not just on paper. I’m comfortable either improving an existing setup or helping build something new, depending on what stage you’re at. I keep communication straightforward, share progress along the way, and flag issues early so there are no surprises later. If you want, you can share a bit more about the current setup or the goal you’re trying to reach, and I can let you know how I’d approach it. Thanks, Jesse

@serhiih25

✅✅✅✅✅ Ready To Support You Fully ✅✅✅✅✅ ----------------------- Your setup is clear: a fixed 46-camera hemispherical rig with known intrinsics, exported extrinsics as start poses, and COLMAP struggling to preserve rig consistency during refinement. The goal is accurate pose optimization + clean sparse cloud export for 4D Gaussian Studio. I’ve worked with COLMAP, OpenCV calibration pipelines, and custom SfM workflows. My approach would be: • Validate intrinsic/extrinsic import and coordinate system consistency • Use rig-aware reconstruction (camera groups + shared intrinsics control) • Constrain bundle adjustment to prevent rig deformation • Extract refined poses + sparse cloud into your required JSON format • Deliver a reusable Python script wrapping the full COLMAP pipeline COLMAP is still the right choice—but it must be constrained properly for multi-camera rigs. Let’s stabilize your reconstruction pipeline correctly.

@DngPhgNam

⭐⭐⭐⭐⭐ ✅Hi there, hope you are doing well! I have worked on similar multi-camera rig 3D reconstruction projects where precise camera poses and intrinsics enabled smooth, accurate 3D models with seamless integration into post-processing pipelines. The key to success is accurate pose refinement using initial calibrations and careful handling of overlapping and non-overlapping cameras in Colmap to ensure a clean reconstruction. Approach: ⭕ Integrate your JSON extrinsics and intrinsics into a robust Colmap pipeline ⭕ Refine poses using bundle adjustment tailored to the 46-camera hemisphere rig ⭕ Automate the workflow via a custom Python script that inputs video frames, calibrations, and outputs precise poses and point clouds ⭕ Export results in your target JSON formats compatible with 4D Gaussian Studio ❓ Do you have any preferred parameters or constraints in Colmap for refinement? ❓ Would you like the script optimized for batch processing multiple sessions? I am confident I can deliver a reliable Colmap-based solution that refines your camera poses accurately and outputs clean point clouds for your 6DoF film workflow. Let's start refining this together to achieve high-precision results. Best regards, Nam
