Planning a 2K stereoscopic surgical capture program

What should be decided before choosing cameras?

Begin with the observation the research team needs. An external view of an operation and an internal scope view provide different information. Define the procedure types, field of view, expected motion, recording duration, and whether additional data streams are needed.

Identify the institutional teams responsible for clinical workflow, privacy, information security, engineering, and contracting. Camera placement, power, cabling, cleaning, and local device policies require site-specific review. Do not treat equipment installation as a purely technical decision independent of the operating room.

The project plan should name the person who can stop recording and the process for handling an interruption. Research collection must fit the approved clinical workflow. A successful program should not depend on a surgeon troubleshooting a recorder during patient care.

Which technical specifications should be written down?

Calibration and image processing choices should be reproducible. OpenCV: camera calibration and 3D reconstruction is a technical reference for stereo calibration and rectification. The capture team should document which operations actually apply to its setup rather than assuming a generic calibration file is sufficient.

Include a change log for configuration updates. If resolution, optics, mounting, or processing changes mid-program, the dataset should preserve that distinction. Otherwise a downstream researcher may interpret a capture change as a change in the procedure.

How can a pilot test the full workflow?

An approved pilot should cover setup, recording, end-of-case handling, secure storage, review, and delivery. Test the transitions as carefully as the recording itself. Failures often become visible when a session restarts, a disk fills, or one file segment ends before another.

• Confirm that both views record and can be paired after export.
• Verify expected image dimensions and timing from the actual files.
• Check representative motion, lighting, occlusion, and long recordings.
• Reconcile recorded sessions against a privacy-appropriate internal manifest.
• Exercise the process for a failed recording and a withheld release.

Keep pilot observations concrete: what failed, how it was detected, who resolved it, and which requirement changed. A short issue log can be more informative than a general statement that the system worked.

What should count as usable footage?

Define acceptance around the research task. The entire case may be needed for sequence understanding, while another project may require selected phases. State how missing views, timing drift, image artifacts, and interrupted recordings are handled. Avoid a single vague “good quality” criterion.

Track both accepted and excluded material at an appropriate aggregate level. Excluding every difficult case can change the collection’s usefulness and the claims a researcher can make from it. Share those limitations in the release documentation.

How should responsibilities and compensation be arranged?

Specify who supplies equipment, installs and supports it, operates the workflow, reviews recordings, and pays for preparation. Separate the contribution of the institution, the recording team, and any individual expert work. Confirm the authorized contracting and payment arrangements.

Operavue provides an optional recording headset for surgeons who want to capture their procedures, alongside opportunities to license existing archives. The capture plan defines the hardware, exact recording specifications, institutional approvals, and workflow. Proposed minimum guarantees and revenue shares depend on the agreed rights, collection scope, quality, and commercial terms. Start with a non-patient description of the setting and intended procedures; the capture protocol comes through a separate project discussion.
