Hello StereoLabs Team and Community,
I am building a 360-degree vision system using four ZED-X cameras with mixed focal lengths: two at 2.2mm and two at 4mm. The key challenge in my setup is that the cameras are mounted facing outwards, resulting in no overlapping fields of view (FOV).
The Challenge with ZED360
I understand that the ZED360 solution requires significant overlap (typically \ge 50%) between cameras to align their body-tracking data effectively. Since my configuration has no overlap, ZED360 is not viable for this project.
My Calibration Goal and Proposed Method
I am seeking an alternative solution to determine the extrinsic poses (position and orientation) of all four cameras.
My specific objectives are:
- Non-Overlapping Calibration: Successfully calibrate a multi-camera system where FOVs do not intersect.
- Mixed-Focal-Length Support: Integrate both 2.2mm and 4mm ZED-X cameras into a single, cohesive coordinate system.
- Manually Defined Origin: Align all camera poses relative to a manually defined origin point at the physical center of the camera rig, which is not visible to any camera.
I plan to use a large A0-sized CharUco board as my calibration target. I am currently exploring external libraries like Calico, which is designed for non-overlapping camera networks using rigidity constraints.
Inquiry for StereoLabs Custom Services
Does StereoLabs offer any Custom Engineering or Professional Services to handle a specialized multi-camera calibration project like this?
If so, could you please direct me to the correct contact or department that handles custom solutions involving non-standard multi-camera configurations, non-overlapping FOV, and user-defined world origins?Thank you for your guidance!
